U.S. NUCLEAR REGULATORY COMMISSION INSTRUCTIONS FOR COMPLETING
NUCLEAR MATERIAL TRANSACTION REPORTS
DOE/NRC Form 741, “Nuclear Material Transaction Report,” and
DOE/NRC Form 740M, “Concise Note”
1 PURPOSE AND SCOPE
The U.S. Nuclear Regulatory Commission (NRC) and the U.S. Department of Energy (DOE)
jointly use a Nuclear Materials Management and Safeguards System (NMMSS). This system is
the U.S. national database used by DOE and NRC for tracking nuclear material.
Common reporting forms and formats are used to minimize the reporting burden on licensees 1
required to provide nuclear material data to one or both agencies in accordance with current
regulations or contractual obligations. In this manner, licensees can file one report to meet the
reporting requirements of both NRC and DOE. Compliance with specific reporting requirements
is monitored by the agency that requires the specific data. NRC regulations require that the
reports be submitted in computer-readable form. A licensee may use any blank blocks on the
paper DOE/NRC forms for other business purposes.
DOE requires all NRC licensees to report to NMMSS all receipts, transfers, and inventories of
U.S. GOVT-owned, loaned, or leased material in their possession. A DOE/NRC Form 742,
“Material Balance Report,” and a DOE/NRC Form 742C, “Physical Inventory Listing,” must be
filed to report quantities of 0.5 or greater of the reporting unit specified in the DOE Manual M
474.1-2. Reports to NMMSS for all U.S. GOVT-owned, -loaned, or -leased material are required
to follow the U.S. GOVT’s reporting requirements as specified in DOE Manual M 474.1-2,
“Nuclear Materials Management and Safeguards System Reporting and Data Submission.”

1.1 Transaction Data
The DOE/NRC Form 741, “Nuclear Material Transaction Report,” is the means for entering
transaction data into the NMMSS. DOE/NRC Form 741 must be completed in accordance with
the instructions in this NUREG and must be submitted in computer-readable format.
Instructions for creating the computer-readable submittal are found in NMMSS Report D-24,
“Personal Computer Data Input for NRC Licensees.”
DOE/NRC Form 741 is used to report physical transfers of nuclear materials between facilities.
The report is also used to convey information on transactions such as inventory corrections that
otherwise increase or decrease obligation balances or nuclear material categories within a
facility.
The NMMSS relies heavily on the quality of the data reported by the facilities involved in nuclear
activities. The data submitted to the NMMSS are subject to evaluation according to the
restrictions placed on nuclear activity by the policies of various governing agencies of the United

The term “licensee” here denotes an NRC or Agreement State licensee or an NRC certificate
holder.

NUREG/BR–0006, Rev. 6

States. After being verified as acceptable within the restrictions of the system, the data are
entered into the NMMSS database.
NRC licensees must provide a DOE/NRC Form 741 to NMMSS in a computer-readable format
following the instructions in this NUREG and NMMSS Report D-24. Both the shipper and the
receiver are required to submit DOE/NRC Form 741. The receiver should confirm that the
quantity received is consistent with the shipper's report. When significant shipper-receiver
differences (SRDs) are identified, they must be resolved and their root causes corrected. The
regulatory intent is to require material control and accounting (MC&A) systems to promptly
detect and resolve all significant SRDs. Comparisons of shippers’ and receivers’ reports are
necessary both to confirm the acceptability of shippers’ and receivers’ values for establishing
the book accounting amounts for received material and to detect unacceptable shippers’ or
receivers’ values. Comparisons typically involve item verification, seal integrity, gross weights,
nondestructive assay (NDA) measurements (if appropriate), and destructive measurements (if
appropriate).

1.2 Regulatory Authority
Title 10 of the U.S. Code of Federal Regulations (10 CFR) sets forth reporting requirements for
specified activities as follows.
Reporting transactions for special nuclear material (SNM):
NRC regulations 10 CFR 70.54, 72.78, 74.15, 75.34, 76.113, 76.115, 76.117, and 150.16 require,
in part, that each licensee who transfers or receives SNM of any origin must complete, in
computer-readable format, a DOE/NRC Form 741. This should be done in accordance with
instructions in this NUREG document whenever the licensee or certificate holder transfers or
receives a quantity of special nuclear material of 1 gram or more contained U235, U233, or
plutonium.
Reporting transactions for source material:
NRC regulation 10 CFR 40.64(a) states, in part, that except as specified in paragraphs (d) and
(e) of that section and 10 CFR 150.17, each licensee must complete and distribute a DOE/NRC
Form 741 when the licensee in any manner transfers, receives or adjusts the inventory, of
source material of foreign obligations by 1 kilogram or more or imports or exports 1 kilogram of
source material. The DOE/NRC Form 741 must be completed in computer-readable format in
accordance with instructions in this NUREG and in NMMSS Report D-24.
Reporting transactions for source material or SNM in accordance with an agreement with the
International Atomic Energy Agency (IAEA):
NRC regulation 10 CFR 75.31 requires licensees to complete and distribute DOE/NRC Form
741 for all source or SNM inventory changes, including shipments, receipts, onsite gains and
losses, and any other inventory adjustments. These reports must be in computer-readable
format and must be based on the records kept in accordance with 10 CFR 75.22, 75.31, 75.32,
75.33, 75.34, and 75.35.

NUREG/BR–0006, Rev. 6

2

Compliance with these reporting requirements is achieved by completing a DOE/NRC Form 741
and transmitting it in computer-readable format following the guidance in this NUREG and in
NMMSS Report D-24.
In addition, the submission of DOE/NRC Form 741 is normally required as a matter of contract
or lease administration for all Government-owned nuclear material transferred (see DOE Order,
Series 5600, and DOE Manual M 474.1-2, “Nuclear Materials Management and Safeguards
System Reporting and Data Submission”).

1.3 Reporting/Distribution Requirements
Reports are required whenever nuclear material in the types and amounts stated in the
preceding section moves between locations or operations that have been assigned different
reporting identification symbols (RISs) and whenever SNM and source material inventories
change. The nuclear material change data (including burnup, production, measured discards,
and decay) should be documented and reported to NMMSS before or at the same time as the
physical inventory taking, unless another arrangement is authorized by the NRC.
The shipper initiates a DOE/NRC Form 741. If the licensee is involved in a transfer of material
with a party that is not required to prepare a DOE/NRC Form 741, the licensee must prepare
and submit both the shipper’s and the receiver’s section of the Form 741. The most common
situation is when a domestic facility is involved in export/import activities. The domestic facility
must obtain the information necessary to complete the Form 741.
Reports of physical shipments between RISs must show the actual movement of material. In
addition, any information on the material must also be reported. In particular, the obligation of
material by a foreign entity must follow the physical movement of material between RISs. The
exchange of obligations between RISs with no physical movement of material is reported by
using action codes X and Y.
DOE/NRC Form 741 must be submitted to NMMSS in the prescribed computer-readable format.
It was formerly submitted in paper.

1.4 Automated Methods for Submitting Data to the NMMSS
There are several automated methods:
(1)

Telephonic Transfers
A licensee may submit the DOE/NRC Form 741 electronically by using a modem.
To establish an electronic connection with the NMMSS, licensees must contact the
NMMSS security officer to request establishment of a connection with the direct link. If the
facility is a valid facility for the type of link requested (classified or unclassified), the security
officer provides the requester with the appropriate forms to complete.
Upon receipt of the completed forms, the security officer creates a user ID and password
and establishes an account for the facility. The user ID and password are then forwarded
to the user facility along with a password acknowledgment form. The licensee signs the

3

NUREG/BR–0006, Rev. 6

acknowledgment form and returns it to the security officer who, then activates the user ID
and password.
(2)

Data submittals on diskettes
DOE/NRC Form 741 must be submitted in computer-readable format. NMMSS Report D24 provides instructions on handling techniques, format requirements, and data submittals
using diskettes.

(3)

Safeguards Management Software (SAMS)
The SAMS is a miniature version of the Nuclear Materials Management and Safeguards
System (NMMSS). This software allows the user to make edit checks, generate various
reports, perform import and export transactions, and complete material balance and
inventory data. The SAMS program with the appropriate formats and user prompts may be
obtained from the NMMSS operator free of charge.

(4)

New and Modified Methods of Transferring Electronic Data
New and modified methods of transferring electronic DOE/NRC Form 741 data to NMMSS
may be authorized by the NRC. Confirmation of additional methods for the transfer of this
data may be obtained by contacting the NMMSS operator.

1.5 Documentation and Distribution
The completed DOE/NRC Form 741, in computer-readable format, should be submitted to the
NMMSS operator. Confirm the address and mechanism of providing data to NMMSS by calling
the NMMSS operator. Note that specific submission instructions depend upon whether the Form
741 is classified or unclassified information. Additional distribution information is contained in
Sections 2.2, 3.2, and 4.4 of this NUREG.
Any DOE/NRC Form 741 which is classified must be documented and handled in accordance
with all pertinent security requirements. The same goes for any DOE/NRC Form 741 which is
unclassified. Each person who is to receive a copy of the report must be verified as a qualified
recipient prior to distribution. Please confirm the address prior to sending documents to NMMSS
or other recipients. Also please formally provide classification guidance to NMMSS after a
decision to classify, declassify, or make any change in previously submitted guidance.

GENERAL INSTRUCTIONS

2.1 Instructions for Completing DOE/NRC Form 741
If the DOE/NRC Form 741 is reporting an onsite gain or loss, review the instructions for block 6,
(ACTION CODE), and the special instructions for the M action code in Section 3 of this NUREG
before completing the form.
The numbered instructions below correspond to the numbered blocks on the DOE/NRC Form
741. Each shipper of reportable quantities of SNM or source material (refer to blocks 26n and
26q) must send a DOE/NRC Form 741 to the NMMSS operator and a copy to the receiver’s
NUREG/BR–0006, Rev. 6

business address preferably on the same day the material is shipped and, in any case, no later
than the close of business the next working day. In the case of spent fuel shipments, in
accordance with 10 CFR 73.37, the date of shipment is “Safeguards Information” until 10 days
after the shipment or the last shipment in a series of shipments is received. Therefore, the
DOE/NRC Form 741 should be stamped “Safeguards Information” and handled according to 10
CFR 73.21.
Burials are reported when shipped. The burial site operator must prepare and transmit
DOE/NRC Form 741 to NMMSS to document receipt and disposal. The electronic formats for
the DOE/NRC Form 741 are given in NMMSS Report D-24.

date the correction is recorded or the acknowledgment made, as appropriate.

22c.

RECEIPT (entry required by receiver) - Enter the date the nuclear material is received.

22d.

RECEIVER’S MEASUREMENT (entry required by receiver) - Enter the date the nuclear
material is measured by the receiver. This entry is required only if receiver’s action code
is E.

22e.

RECEIVER’S CORRECTION (entry required by receiver) - If the document is an
acknowledgment or a correction to a previously issued transaction report, enter the date
the correction is recorded or the acknowledgment made, as appropriate.
In the case of imports or exports, licensees must complete a separate DOE/NRC Form
741 to document the foreign party action, including action dates in blocks 22a and 22c,
as applicable.

23a.

MISCELLANEOUS - Leave blank.

23b.

CONCISE NOTE ATTACHED - Enter an X if a Concise Note is attached.

23c.

UK REPORTABLE - Facilities reporting material transfers involving facilities in the United
Kingdom (UK) must indicate in this block whether the shipment is reportable or nonreportable to the IAEA. Check YES for reportable or NO for non-reportable.

24.

TOTAL GROSS WEIGHT - Enter the total gross weight of the shipment rounded to the
nearest kilogram. An approximate or estimated gross weight rounded to the nearest
kilogram is acceptable. Make no entry for M action code transactions, receipts, and
correction documents.

25.

TOTAL VOLUME (Waste Transfers Only) - For transfers of nuclear material to or from
nuclear waste sites (i.e., if the shipper or receiver RIS begins with the letter V), enter the
volume of the material to be buried, stated in cubic feet rounded to the nearest cubic foot.
An entry in block 25 is not required for transfers to nuclear laundry services.

26.

SHIPPER’S DATA - Shipper’s data are entered in block 26. Receiver’s data are entered
in block 27. Receivers should review the instructions for block 27 before completing the
block.
Shipper and receiver measurement data are entered on DOE/NRC Form 741 for each
batch of material. For licensees reporting pursuant to 10 CFR Part 75 requirements or if
the transfer is an import or an export, a batch is a portion of nuclear material that is
handled as a unit for accounting purposes at a key measurement point (KMP) and whose
composition and quantity are defined by a single set of specifications or measurements.
The batch may be in bulk form or contained in a number of separate items. If the
shipment is an export or is being reported pursuant to 10 CFR Part 75, fuel assemblies
or loose rods or fuel pins must be listed separately with the identifying label serving as a

NUREG/BR–0006, Rev. 6

8

unique batch name. Fuel assemblies can be reported as “average” enrichment as long
as the appropriate accounts (material types 10, 20, 81, etc.) are properly adjusted.
Material being transferred may be listed on one line of DOE/NRC Form 741 if the material
is all of the same material type, composition, ownership, and weight percent isotope
(except as noted in the next paragraph). Material differing in any of these data elements
must be listed on separate lines.
Two or more lines may be necessary to describe a single batch (e.g., spent fuel
assemblies, mixed oxide fuel). If a batch consists of several types of nuclear material,
several consecutive lines should be used to describe the batch. The batch name should
be repeated on all lines used to describe a single batch. In block 26e the number of
items is also repeated on all lines with the same batch name.
The above general rules for grouping or batching material for reporting purposes are also
applicable to licensees reporting imports or exports pursuant to 10 CFR Part 40 or 74.
Batch names are optional for other transactions reported pursuant to 10 CFR Part 40 or
74.
26a.

BACK REFERENCE NUMBER - Enter the appropriate back reference number
adjustments to previously completed DOE/NRC Form 741 documents.
Licensees must change the back reference numbers for action codes C and D and for
action code M when reporting adjustments. Both the back reference change digit and the
back reference line number must be reported.
The back reference change digit represents the change digit of the document being
corrected for a nullifying entry and the change digit of the document now being completed
for a correcting entry. For example, if the DOE/NRC Form 741 being corrected is the
original, or if the line being entered represents an addition only, enter 0 (zero).
The back reference line number represents the line number of the line being corrected
for a nullifying entry and the line number of the corresponding nullifying line for a
correction entry. If the line being entered represents an addition only or represents a net
change, enter 000000 (zeros).

26b.

LINE NUMBER - In providing detailed measurement data, enter a line number.
Beginning with 01 for the first line of detailed shipper’s data, and increase the line number
by one for each additional line of detailed shipper’s data entered on the form (up to 99).
When two or more lines of measurement data refer to a single batch, repeat the unique
batch name for each line of the batch data. For example, repeat the batch name when
different material types of multi-enrichment fuel rods are entered on separate lines or
when UF 6 product material and UF 6 heel material in a cylinder are reported on separate
lines.

26c.

TYPE OF INVENTORY CHANGE - All changes to inventory that meet the reporting
criteria must be reported on DOE/NRC Form 741. There are 29 inventory change type
(ICT) codes listed in Appendix B. Many of these 29 codes are used by NMMSS for
internal reporting activities. And need not be entered by the licensee in this block. Other
codes, such as the codes for de-exemption use, de-exemption quantity, exemption use,
exemption quantity, and termination of non-nuclear use are seldom used. These codes

9

NUREG/BR–0006, Rev. 6

are occasionally used for the facilities identified in the instructions for block 26h and are
addressed as they occur through direct contact between the licensee and the NRC.
There is a third group for which entry in this block is mandatory.
Appendix B explains the ICT codes and indicates whether they are to be entered in block
26c.
When the ICT code for a normal operational loss (LD), measured discard (TW), or (LA)
accidental loss is used, additional information is required. There are four dispositions of
measured discards for which are to be reported:
A
G
L
H

when material is discarded into the atmosphere
when material is discarded through ground effluents
when material is discarded into a pond or lagoon
when material is transferred to a holding area at the facility pending possible
shipment offsite for disposal

When any of the above activities occurs, a DOE/NRC Form 741 should be prepared.
The shipper should enter its RIS in the SHIPPER’S RIS block (block 1) and the same RIS
in the RECEIVER’S RIS block (block 2), but append an A, G, L, or H, to the receiver’s RIS
as appropriate. For example, if a facility with RIS XYZ discards material to a lagoon, the
transaction on the DOE/NRC Form 741 would be from XYZ to XYZL.
26d.

IDENTIFICATION (ITEM/BATCH NAME) - Enter a name or number, or a combination of
both, that identifies the reporting facility and the batch of material being shipped. If the
licensee is reporting pursuant to 10 CFR Part 75, or if the transfer is an import or export,
the shipper or receiver enters a name which identifies a unique portion of nuclear
material handled as a unit for accounting purposes. For fuel assemblies pins and rods,
the batch name should be the identification numbers of the fuel assembly pin or rod.
In the case of an import, the receiver must use the same batch name as the shipper
provided the shipper’s batch name conforms to the above specifications. If it does not,
see the Concise Note instructions (Section 5).

26e.

NUMBER OF ITEMS - Enter the number of similar items of which the line entry consists
(e.g., cylinders, packs, drums, bird cages, bottles, tank vessels). When reporting fuel
pins, rods, or plates, report the number of separate fuel pins, rods, or plates involved.
When reporting fuel assemblies, report the number of complete assemblies represented
on the line entry. In the case of transfer of bulk material, enter a 1. Leave blank if an M
action code is used.

If the quantity to be entered is equal to or greater than 0.5 of the reporting unit, the
quantity should be rounded up to the next whole reporting unit. If the quantity to be
entered is less than 0.5 of the reporting unit, the quantity should be rounded down to the
next whole reporting unit.
26o.

ELEMENT LIMIT OF ERROR - Limits of error need only be reported by licensees who
are authorized to possess at any time and location SNM in a quantity exceeding one
effective kilogram and authorized to use SNM for activities other than those involved in
the operation of a nuclear reactor licensed pursuant to 10 CFR Part 50; are involved in a
waste disposal operation; or are authorized to possess sealed sources (under 10 CFR
70.58(e)).
Complete when the total shipment contains more than 50 grams of U235, U233, or
plutonium, or any combination of these. Enter the limit of error for each element entry
using the same weight units as in block 26n, except where the line entry represents a
sealed plutonium-beryllium source (composition code 481); samples each of which has
been determined by other means to contain less than 10 grams U235, U233, or plutonium
(composition code 771); and reactor-irradiated fuels (composition code 375) involved in
research, development, and evaluation programs in facilities other than irradiated-fuel
reprocessing plants.
Limits of error are to be at the 95% confidence level, propagated by the uncertainties of
the weight measurement, the chemical analysis, and the sampling method. Limits of
error are not applicable to source material. Licensees making onsite transfers between
two different RISs or within the same RIS are exempt from supplying limits of error data
for the transfers. (Transfers between a license-exempt operation and a licensed
operation at the same location are not considered onsite transfers, and limits of error are
required.)

26p.

WEIGHT % ISOTOPE - Enter the weight percent of the isotope U235 if the uranium is
enriched or depleted in U235. If plutonium, enter the weight percent of the isotope Pu240. If
Pu238, enter the weight percent of the isotope Pu238. Report weight percent to at least
two, but not more than four, decimal places, depending upon the accuracy of the
measurement method employed (for example, XX.XXXX%). For U233, enter the parts per
million of U232. This block does not apply to natural uranium and thorium.
Use
235
separate lines to report material of different enrichments. The Pu and U content of
irradiated fuel must be determined and reported upon removal of the spent fuel from the
reactor core. Reactor operators may report the total nonfissile isotope instead of Pu240 in
this block for spent fuel if the computer codes the operator uses have this limitation.

26q.

ISOTOPE WEIGHT - Enter the isotope weight. If enriched uranium or U233, enter weight
to the nearest gram of U235 or U233 as appropriate. If plutonium, enter the sum of Pu239
and Pu241 to the nearest gram. If Pu238, enter the weight of the isotope Pu238 to the
nearest 1/10 of a gram. For depleted uranium, enter the isotope weight to the nearest
kilogram. Make no entry for other source material.

13

NUREG/BR–0006, Rev. 6

If the quantity to be entered is equal to or greater than 0.5 of the reporting unit, the
quantity should be rounded up to the next whole reporting unit. If the quantity to be
entered is less than 0.5 of the reporting unit, the quantity should be rounded down to the
next whole reporting unit.
26r.

ISOTOPE LIMIT OF ERROR - Limits of error need only be reported by licensees who
are authorized to possess at any one time and location SNM in a quantity exceeding 1
effective kilogram and authorized to use such SNM for activities other than those involved
in the operation of a nuclear reactor licensed pursuant to 10 CFR Part 50; who are
involved in a waste disposal operation; or who are authorized to possess sealed sources
(10 CFR 70.58(e)).
Complete this block when the total shipment contains more than 50 grams of U235, U233,
or plutonium or any combination of U235 and plutonium. Enter the limit of error for each
isotope entry using the same weight units as in block 26n, except where the line entry
represents a sealed plutonium-beryllium source (composition code 481); samples each
of which has been determined by other means to contain less than 10 grams U235, U233,
or plutonium (composition code 771); or reactor-irradiated fuels involved in research,
development, and evaluation programs in facilities other than irradiated-fuel reprocessing
plants.
Limits of error are to be at the 95% confidence level, propagated by the uncertainties of
the weight measurement, the chemical analysis, the isotopic analysis, and the sampling
method.
Limits of error are not applicable to source material.

26s.

SIGNATURE OF AUTHORIZED OFFICIAL AND DATE SIGNED - If submitted on paper,
the report must be signed by an authorized representative of the licensee. Otherwise,
enter the date submitted. Each licensee must establish internal procedures to ensure
that the information provided in the report is accurate and that the report has been
prepared and issued only by the authorized licensee personnel.
Proprietary information must be included when necessary to provide an adequate
response. An application to withhold such information from public disclosure may be
made and will be dispositioned in accordance with the provisions of 10 CFR 2.790. If any
of this information is of particular sensitivity, a request may be made that such
information not be transmitted to the IAEA. Such a request must refer to, and must
conform with 10 CFR 75.12.

2.1.2

Reporting Receiver’s Data

Each receiver of reportable quantities of special nuclear material or source material must
acknowledge receipt of shipments in accordance with the following instructions:

NUREG/BR–0006, Rev. 6

14

•

If the receiver plans to accept the shipper's measurement data without making independent
measurements (B action code), the receiver must, within 10 days of receipt of the material,
submit a DOE/NRC Form 741. There are two options for filling out the form:
(1) complete blocks 1 through 25 and put a zero (0) in block 10, or
(2) complete blocks 1 through 25, enter the shipper’s values in block 26, and repeat the
shipper’s values in block 27.
Facilities reporting pursuant to 10 CFR Part 75 must use the second option. Dispatch the
form in accordance with the instructions in Section 2.3.2.

•

If the receiver makes independent measurements (E action code), the receiver must, within
10 days of receipt of the material:
(1) complete blocks 1 through 25, enter the shipper’s values in block 26, and complete
blocks 27a through 27s of the DOE/NRC Form 741.
(2) dispatch the form in accordance with the instructions in Section 2.3.2.

•

If the receiver intends to make independent measurements within 60 days for source
material or LEU, or 45 days for HEU (N action code), unless an exemption is authorized by
NRC, the receiver shall, within 10 days of receipt of the material:
(1) complete blocks 1 through 25, enter the shipper’s values in block 26, and complete
blocks 27a through 27s of the DOE/NRC Form 741.
(2) dispatch the form in accordance with the instructions in Section 2.3.2; and
(3) after independent measurements are made, follow the instructions for reporting a B or E
action code. If measurements are delayed, they must be completed and reported on
DOE/NRC Form 741 within 60 days for source material and LEU and within 45 days for
HEU after the receipt of each shipment, except in the case of receipts of scrap and
irradiated material.
In the case of a scrap processor receiving several shipments of scrap which are
accumulated and processed together, the recovered quantity of material must be prorated to
the specific transmittal documents and line entries to maintain the one-to-one
correspondence between shipper’s and receiver’s data.

2.3 Distribution of DOE/NRC Form 741
2.3.1

Shipper

Each shipper of reportable quantities of special nuclear material (SNM) or source material must
dispatch a DOE/NRC Form 741, as described below, no later than the close of business the
next working day after the shipment. In the case of spent fuel shipments, in accordance with 10
CFR 73.37, the date of shipment is “Safeguards Information” until 10 days after the shipment or
the last shipment in a series of shipments is received. Therefore, the DOE/NRC Form 741
should be stamped “Safeguards Information” and handled according to 10 CFR 73.21.

4 INSTRUCTIONS FOR CORRECTING A DOE/NRC FORM 741 (C, D, AND M
ACTION CODES or Z PROCESS CODE)
Adjustments are independent actions. Either the shipper or the receiver may initiate an

19

NUREG/BR–0006, Rev. 6

adjustment to a DOE/NRC Form 741 reporting the original shipment or receipt of material or an
adjustment to any previous adjustment to the original. The other party is required to
acknowledge that an adjustment was made, but not required to make the same adjustment to its
records.

4.1 Originator
The originator of the “corrected copy” must:
•

Complete blocks 1 through 25, as appropriate, referring to the copy of DOE/NRC Form 741
being corrected.

•

Insert in block 26a or 27a of the “did-read” line, as appropriate, a three-digit back reference
code. If the line of data has not been previously corrected, a zero (0) should be used.
If
previously corrected, the first digit is the correction number (block 4) from the DOE/NRC
Form 741 being corrected. (If the line of data has been corrected several times, the most
recent correction number should be used.) The next two digits are the line number (block
26b or 27b) on the DOE/NRC Form 741 being corrected.

•

Complete the did-read line, blocks 26b through j and n through r or 27b through j and n
through r, as appropriate, by duplicating the entire line being corrected from the DOE/NRC
Form 741 being corrected and indicating the opposite sign (positive or negative) from the
original one used in reporting the number of items (block e), element weight (block n),
element limit of error (block o), isotope weight (block q), and isotope limit of error (block r).

•

Insert in block 26a or 27a of the “should-read” line, as appropriate, a three-digit back
reference code that references the corresponding did-read line. The first digit is the
correction number of the document being completed; the next two digits are the line number
of the corresponding did-read line.

Repeat this procedure until all lines requiring adjustment have been “backed out” and resupplied
with the correct information.
The did-read and should-read for each line being adjusted should be paired (i.e., consecutive).
One or more changes can be made to each line. Only incorrect lines should be included in a
correction report.
If adding a line to the original document, the back reference should be (000) (block 26a or 27a)
and pairing is not done.
If a line previously reported is split into two or more lines, one of the should-be lines should backreference the did-read line and all others should be considered new additions (000).
If a line is to be voided, only a did-read line should be used (no pairing). Examples of an initial
report and subsequent correction reports are provided in Appendix C.

4.2 Receiver
Within 10 days, the facility receiving the corrected DOE/NRC Form 741 must either:
•

submit a DOE/NRC Form 741 acknowledging the adjustment (which will close a transaction
but will not affect the acknowledging party’s values),

•

submit a DOE/NRC Form 741accepting the adjustment. This closes a transaction and
applies the other party’s adjustment to the acknowledging party’s values.

There is no requirement for both parties to make the same quantity adjustments. However, if
both parties choose to adjust on the same corrected DOE/NRC Form 741, they must both
report the same number of entries and the material types must agree line for line.

4.3 Use of the Z Process Code
If the receiving party agrees to all changes for an action code C document, the receiving party
may utilize process code Z and action code D. Submit a DOE/NRC Form 741 to report data in
blocks 1, 2, 3, 4, 20, 22. The Z code should be entered in block 5b and action code D in block
6b, and block 22 should be completed. The Z process code may not be used by a licensee
reporting per 10 CFR Part 75.

4.4 Distribution of Corrections to DOE/NRC Form 741
The originator should:
•

Submit one copy, in a mutually agreeable format, to the other party in the transaction.

•

Submit one copy to NMMSS. (See Section 1.5 for documentation and distribution of
classified and unclassified reports.)

•

Retain one copy for your file.

Upon receipt of a correction, distribute the completed DOE/NRC Form 741 as follows:
•

Submit one copy to NMMSS. (See Section 1.5 for documentation and distribution of
classified and unclassified reports.)

•

Return one copy to the originator.

•

Retain one copy for your file.

IAEA INVENTORY CHANGE TYPE CODES FOR COMPLETING BLOCKS 26c AND
27c OF DOE/NRC FORM 741

IAEA INVENTORY CHANGE TYPE CODES
All inventory change type (ICT) codes on transaction reports consist of two alphabetic or
numeric characters. The accounting entry type codes used on Material Balance Reports
(MBRs) consist of two digits. In the following pages the number(s) in parentheses following the
alphabetic code represent the MBR line for which the transaction entries correspond. The
standard inventory changes and other entry type are listed below. In transaction reports, all
transactions and operations are understood to be related to individual batches. In MBRs,
corresponding the same codes denote consolidated entries; i.e., the sums of all individual
operations with the same code over the material balance period. In addition, MBRs include
entries related to inventory data and adjustments not reported on transaction reports.
Gains or losses of material which occur based on the total inventory or in which individual effects
to inventories by country of obligation code cannot be determined, should be reported as a loss
to all country obligation balances by applying a one to one ratio by percent of the country of
obligation to the amount of inventory affected to the amount of inventory change. For example, if
decay is reported for plutonium within a reactor and the plutonium balance represents several
different country of obligation balances the following calculations would determine the amount of
decay to apply to each country of obligation code balance.

blending, enrichment, depletion, or burnup.
The first letter denotes the original, the
second letter the resulting category
(E=enriched, N=natural (or “normal”),
D=depleted uranium, EE=change of
enrichment). The material type codes should
be those for both the original and the resulting
material. The weight data should be provided
both for the originating and for the resulting

REQUIREMENT FOR
BLOCKS 26c AND 27c

EXPLANATION

Applicable to licensees subject to the 10 CFR
Part 75 only - The quantity that has to be
added to the rounded sum to make it equal to
the sum of the rounded terms. A rounding
adjustment is made to an entry in the MBR of
which the IAEA has been informed differently
through Inventory Change Reports (ICRs)
and Physical Inventory Lists (PILs), in order
to bring the MBR entry into agreement with
the corresponding figures established on the
basis of ICRs and PILs. In the case of the
book inventory and the inventory
difference(ID) or material unaccounted for
(MUF), the following formulae should be used
respectively.
RABA = PB + ICRMBR – DI – BA, and
RAMF = BA – PE – MF
where ICRMBR is the sum of the consolidated
inventory changes as reported in the MBR,
taken with the appropriate sign if they
represent decreases. All other notations are
as defined for this data element.
No rounding adjustment is needed for the
beginning physical inventory.
The rounding adjustment should be coded
RAXX where XX stands for the code of the
entry to which the rounding adjustment
pertains, e.g., RALN means a rounding
adjustment to the consolidated entry on the
nuclear loss.

GLOSSARY

GLOSSARY
Accountability—The determination of, and current record maintenance of, special nuclear material
(SNM) and source material quantities associated with transfers, measured discards, inventories,
and inventory differences that might result from theft, diversion, or other unidentified loss
mechanisms.
Agreement State—Any State of the U.S. with which NRC, or its predecessor, the Atomic Energy
Commission, has entered into an agreement under Section 274b of the Atomic Energy Act of
1954, as amended.
Book Inventory—The algebraic sum of the most recent physical inventory of the material balance
area and of all inventory changes that have occurred since the physical inventory was taken.
Concise Note—Additional nuclear material transaction, material balance, or inventory data
supplied to the IAEA, in free text format, by facilities engaged in the import and/or export of nuclear
materials and by facilities selected under the provisions of the Agreement between the United
States of America and the IAEA for the application of safeguards in the U.S./IAEA Safeguards
Agreement.
EURATOM—As of January 2002, an organization consisting of the following member countries:
Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the
Netherlands, Portugal, Spain, Sweden, and the United Kingdom.
Foreign obligated nuclear material—Source material or special nuclear material which is subject
to the terms and conditions of an Agreement that the U.S. Government has entered into with
another government or group of governments.
Highly enriched uranium (HEU)—Uranium enriched to 20 percent or greater in the isotope
uranium-235.
International Nuclear Materials Tracking System (INMTS)—A database and information support
system used to manage information on the quantity and location of U.S.-supplied nuclear
materials in foreign countries.
Inventory difference (ID)—The arithmetic difference between a book inventory and the
corresponding physical inventory that closes the material balance period. It is calculated by
subtracting the ending inventory (EI) and removals from inventory (R) from the beginning inventory
(BI) and additions to inventory (A) during the period between physical inventories. Mathematically
ID can be expressed as:
ID = (BI + A - R) - EI

where (BI + A - R) is the book inventory.
Inventory reconciliation—The adjustment of the book record quantity of both elements and fissile
isotopes to reflect the results of a physical inventory. In a broad sense, inventory reconciliation
involves the activities of calculating (1) the ID for the material balance period in question, (2) the
uncertainty value associated with the ID, (3) the active inventory for the period, and (4) any bias
adjustment and/or prior period adjustment associated with the ID value.
Low-enriched uranium (LEU)—Uranium enriched below 20 percent in the isotope uranium-235.
Material balance period—The time span to which a material or physical inventory pertains.

D-1

NUREG/BR–0006, Rev. 6

Nuclear Materials Management and Safeguards System (NMMSS)—The national database and
information system for select nuclear materials controlled by the U.S. Government. This system
was created to support national safeguards and management objectives in domestic and
international programs. The system stores data on nuclear material transactions and inventories,
and produces a wide range of printed reports for use by DOE and NRC and those the licensees
they regulate. The system is used to satisfy the nuclear materials information requirements of
agreements between the U.S. and foreign entities. In addition, the system provides the reporting
interface between facilities selected under the provisions of the U.S./IAEA Safeguards Agreement.
Physical inventory—A physical determination of the quantity of nuclear material on hand at a given
time. The methods of physical inventory and the associated measurements vary, depending on
the material to be inventoried and the process involved. A book inventory between physical
inventory takings can be determined based on the physical inventory quantity from the prior period
together with all subsequent inventory changes associated with the determination of that book
inventory. The primary purpose of a physical inventory is to confirm the absence of (or to detect) a
loss, theft, or diversion of SNM.
Reporting identification symbol (RIS)—A unique combination of three or four letters which is
assigned to each reporting organization by the Department of Energy or the NRC for the purpose
of identification in the NMMSS database.
Shipper-receiver difference (SRD)—The difference between what a shipper claims was contained
in a shipment of SNM and what the receiver claims was received, where both the shipper’s and
receiver’s values are based on measurement.
Source material—Uranium or thorium, or any combination thereof, in any physical or chemical
form; or ores that contain by weight one-twentieth of 1 percent (0.05%) or more of uranium,
thorium, or any combination thereof. Source material includes depleted uranium and natural
uranium, but not special nuclear material.
Special nuclear material (SNM)—Plutonium, uranium-233, and uranium enriched in the isotope
233 or 235; any other material that the NRC, pursuant to the provisions of Section 51 of the Atomic
Energy Act of 1954 (as amended) determines to be SNM; and any material artificially enriched with
any of the foregoing materials, but not source material.

INTRODUCTION

Special procedures must be used to implement some of the reporting requirements of the U.S.
Bilateral Agreements for Peaceful Nuclear Cooperation. These Agreements for Cooperation are
one means to satisfy Section 123 of the Atomic Energy Act of 1954 and allow the U.S. nuclear
industry to trade with foreign countries/entities. The Agreements require that the U.S. track and
report foreign-obligated nuclear materials and nuclear material produced from obligated material
from these countries/entities. A foreign obligation is a commitment by one government to another
to treat nuclear materials, nonnuclear materials, and equipment and components in a manner
consistent with the Agreement signed between the two governments.
In addition to these Agreements for Cooperation, the U.S. is also required (pursuant to the
U.S./Russian Agreement concerning the disposition of HEU extracted from nuclear weapons), to
track and report to Russia the imports, exports, and use of Former Soviet Union down-blended
highly enriched uranium. Although not a U.S. Bilateral Agreement for Peaceful Nuclear
Cooperation, this Agreement contains similar reporting requirements and will be tracked as such.
Facilities that are importers and/or exporters of nuclear material should also comply with the
Agreement.
2.

IMPORTS

For U.S. facilities importing nuclear material with foreign obligations, the relevant obligation
information will be supplied by the appropriate Government agency [DOE, Department of State
(DOS) or NRC] in advance of the receipt. DOE, DOS, or NRC will notify U.S. facilities exporting
nuclear material with foreign obligations of the relevant obligation information in advance of the
nuclear materials receipt at the facility. The notification will provide the information necessary to
complete blocks 17 through 21, if applicable.
a.

For imports, the foreign obligation information can be (1) the country/entity from which the
nuclear material was shipped and/or (2) the country/entity attaching “third-party
obligations.” In most cases, for imports from a country that has made the entire shipment
subject to the Agreement, the total import quantity will be obligated. If only a portion of the
shipment is subject to an Agreement (third-party obligation), that amount will be clearly
specified on the documentation.

b.

The Government notification will supply the following information for the completion of
blocks 17- 21: (1) the country/entity of obligation, (2) the material type, and (3) the amount
obligated. See Table 1 below for country/entity codes. See Table 2 below for reportable
obligated material types and quantities.

Completion of Obligation Information
Block 17: LINE NUMBER - The shipper will enter a sequential number (01 through 99) for
each obligated country or material. If there is more than one separate obligation or more
than one obligated material type, enter the appropriate numbers in the subsequent lines.
Block 18: COUNTRY OF OBLIGATION - For each line enter the code in Table 1 that
represents the country/entity of obligation.
Block 19: MATERIAL TYPE - For each line enter the domestic code in Table 2 that
represents the material obligated.
Block 20: OBLIGATED ELEMENT WEIGHT - For each line enter the weight obligated in
the reportable quantity specified in Table 2.
Block 21: OBLIGATED ISOTOPE WEIGHT (For Enriched Uranium Only) - For each line
of enriched uranium, enter the obligated isotope weight in grams. (Obligated U235 is
restricted to uranium enriched to 5 percent or less, unless higher enrichment is authorized
or approved by the U.S. GOVT.)

DOMESTIC TRANSFERS, INTERNAL TRANSACTIONS, AND EXPORTS

For U.S. facilities shipping or exporting material with foreign obligations, or for the reporting of
onsite gains and losses, the obligations on the material must be stated as such in blocks 17-21.
a.

For domestic transfers, blocks 17 through 21are filled out as for imports (Section 2 above).
However, the obligation information will not be supplied by a government notification. The
U.S. shipper will assign the appropriate obligations on the material, if any, and complete the
line number, country/entity of obligation, material type, and obligated weight, if applicable.
The U.S. receiver will complete the matching obligation information as assigned by the
shipper.

b.

For internal transactions (i.e., burnup, decay, production, measured discards, accidental
losses or gains, category changes, fission and transmutation, inventory differences, etc.),
enter the line number, country/entity of obligation, material type, and obligated weights, if
applicable, for the material.

c.

For exports, the U.S. shipper will complete both the shipper’s and receiver’s DOE/NRC
Form 741. If the U.S. shipper is exporting foreign obligated material, the U.S. shipper will
complete blocks 17 through 21 for each obligated country/entity or material exported.
NOTE: If the export requires an NRC export license, the license must specifically permit
the export of that obligated material on the face of the license.
