U.S. NUCLEAR REGULATORY COMMISSION
INSTRUCTIONS FOR THE PREPARATION AND DISTRIBUTION OF
MATERIAL STATUS REPORTS
DOE/NRC FORMS 742, "MATERIAL BALANCE REPORT," AND
742C, "PHYSICAL INVENTORY LISTING"
1 INTRODUCTION
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 certain 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 the NRC and DOE. Compliance with specific reporting
requirements is monitored by the agency that requires the specific data. NRC regulations
require that licensees submit the reports 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 the NMMSS all receipts, transfers, and inventories
of U.S. Government-owned, loaned, or leased material in their possession. Licensees must file
a DOE/NRC Form 742, "Material Balance Report," and a DOE/NRC Form 742C, "Physical
Inventory Listing," to report quantities of 0.5 or greater of the reporting unit specified in DOE
Orders Series 470 (DOE Order 470.4, "Safeguards and Security Program," and DOE M 470.4-6,
"Nuclear Material Control and Accountability").
1.1 Material Status Reports
DOE/NRC Forms 742 and 742C are the means for submitting material balance and inventory
data to the NMMSS. The information 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 appear in NMMSS Report D-24, "Personal Computer Data Input for
NRC Licensees."
Licensees use DOE/NRC Form 742 to report a summary of activity for a specified material within
a given time period. The report conveys activities such as the beginning balance, shipments
and receipts involving other facilities, how much material has decayed, how material has been
downblended, and the ending balance. This information is useful to validate a facility's ending
inventory.
Licensees use DOE/NRC Form 742C to report a facility's inventory as of a specified date. The
report lists, for each material type category, the amount of material in the facility's possession or
in transit to the facility at the time of the inventory process. The form can show each individual
1

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

NUREG/BR-0007, Rev. 6

batch or summarize totals of "like" batches. The totals for each material type category must
match the ending balance in the corresponding material balance report (DOE/NRC Form 742).
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
States. The NMMSS accepts the data after they are verified as acceptable within the restrictions
of the system.
1.2 Regulatorv Authority
NRC regulations require each licensee who possessed during a reporting period special nuclear
material (SNM) in a quantity totaling 1 gram or more of contained uranium (U)235, U233, or
plutonium to prepare and submit in computer-readable format reports concerning SNM received,
produced, possessed, transferred, consumed, disposed of, or lost. The reporting periods for
facilities subject to Title 10, Section 74.51, "Nuclear Material Control and Accounting for
Strategic Special Nuclear Material," of the Code of FederalRegulations (10 CFR 74.51) are
October 1 to March 31 and April 1 to September 30 of each year. These reports must be filed
within 30 days of the end of the period covered by the report, unless the NRC authorizes an
alternate date. Reports for facilities subject to 10 CFR 74.19(c), 10 CFR 74.31(c)(5),
10 CFR 74.33(c)(4), or 10 CFR 74.33(c)(6) are to be made and filed within 60 days of beginning*
the physical inventory, unless the NRC authorizes an alternate date. If licensees are reporting
pursuant to 10 CFR Part 75, "Safeguards on Nuclear Material-Implementation of U.S./IAEA
Agreement," they are to dispatch reports as soon as possible but no later than 30 days from the
start of the physical inventory taken as part of the licensee's material control and accounting
procedures. All other licensees, including those subject to 10 CFR 150.17, "Submission to
Commission of Source Material Reports," shall submit a report no later than March 31 of each
year.
Licensees must complete a separate DOE/NRC Form 742 and 742C for each material type (El,
E2, E3, E4, 50, 70, 83, and 89) of SNM for which a reportable quantity is possessed or a
reportable inventory change has occurred during the period. For SNM, reportable quantities are
defined as 1 gram or more; for source material, the reportable quantity is 1 kilogram or more.
For reporting purposes, quantities of 0.5 or more are to be rounded up to the next whole unit.
Each Federal or State licensee that possessed during a reporting period 1 kilogram or more of
foreign obligated source material (material types 10, 81, and 88) must submit a statement of
foreign obligated source material inventory. DOE/NRC Form 742 may be used. The reporting
period is October 1 to September 30 of each year (unless the NRC authorizes an alternate
period). The reports must be filed as specified in facility attachments (FAs) if the licensee is
reporting pursuant to 10 CFR Part 75 for all source material and SNM.
In addition, each licensee that possesses, or that had possessed in the previous reporting
period, 1 kilogram or more of uranium or thorium source material pursuant to the operation of
enrichment services, downblending uranium that has an initial enrichment of the U235 isotope of
10 percent or more, or the fabrication of mixed-oxide fuels shall complete and submit DOE/NRC
Forms 742 and 742C for all source material that the licensee has received, produced,
possessed, transferred, consumed, disposed of, or lost. These reports are to be submitted
within 30 days of September 30 of each year or with the licensee's annual material balance
reports required under 10 CFR Part 72, "Licensing Requirements for the Independent Storage of
NUREG/BR-0007, Rev. 6

Spent Nuclear Fuel and High-Level Radioactive Waste, and Reactor-Related Greater than
Class C Waste"; 10 CFR Part 74, "Material Control and Accounting of Special Nuclear Material";
and 10 CFR Part 150, "Exemptions and Continued Regulatory Authority in Agreement States
and in Offshore Waters under Section 274."
SNM and source reports shall be submitted for each reporting identification symbol (RIS)
account, including all holding accounts.
Refer to DOE Orders 470.4 and DOE M 470.4-6 for U.S. Government-owned material holdings.
1.3 Preparation and Submission of DOE/NRC Forms 742 and 742C in ComputerReadable Format
NMMSS Report D-24 provides instructions for preparing DOE/NRC Forms 742 and 742C in
computer-readable format as required for submittal. The Safeguards Management Software
(SAMS) is a miniature version of the NMMSS. This software allows the user to import and
export data; make edit checks; generate various reports; and create material balance, inventory
data, and transaction data. It has the capability to export data into the required NMMSS
predefined computer-readable format outlined in NMMSS Report D-24. The SAMS program
may be obtained from the NMMSS operator free of charge.
All reporting forms must include proprietary information when necessary to provide an adequate
response. An application to withhold such information from public disclosure may be made, and
will be disposed of, in accordance with the provisions of 10 CFR 2.390, "Public Inspections,
Exemptions, Requests for Withholding." If any of this information is of particular sensitivity, the
licensee may request that the information not be physically transmitted to the International
Atomic Energy Agency (IAEA). Such a request must refer to, and conform with, 10 CFR 75.12,
"Communication of Information to IAEA."
Licensees can submit data to the NMMSS via the following three methods:
(1)

Telephonic Transfers to the NMMSS
A licensee may submit DOE/NRC Forms 742 and 742C electronically by using a modem.
To establish an electronic connection with the NMMSS, licensees must contact the
NMMSS security officer to request the 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 will provide the requester with the appropriate forms to complete.
Upon receipt of the completed forms, the security officer will create a user identification
and password and establish an account for the facility. The user identification and
password will then be forwarded to the user facility along with a password
acknowledgment form. The licensee will sign the acknowledgment form and return it to
the security officer, who will then activate the user identification and password.

(2)

Data Submittals on Computer Media
Licensees should submit DOE/NRC Forms 742 and 742C in computer-readable format
unless reporting under 10 CFR 40.64(b). NMMSS Report D-24 provides instructions on
3

NUREG/BR-0007, Rev. 6

packaging, data format requirements, acceptable media types, and the mailing address
for the submittal of data on computer media.
(3)

New or Modified Methods of Transferring Electronic Data
The NRC may authorize new or modified methods of transferring electronic DOE/NRC
Form 742 and 742C data to the NMMSS. Licensees may confirm authorization to use
additional methods for the transfer of these data by contacting the NMMSS operator's
program administrator.

1.4 Documentation and Distribution
The completed DOE/NRC Forms 742 and 742C must be submitted to the NMMSS operator.
Before submitting data, licensees should confirm the address of the NMMSS and the method of
providing data by calling the NMMSS operator. Note that the specific documentation and
distribution instructions depend on whether the completed DOE/NRC Form 742 or 742C
contains classified or unclassified information.
Any DOE/NRC Form 742 or 742C that is classified must be documented and handled in
accordance with all pertinent security requirements. All other submissions that are not classified
are considered to be proprietary material control and accounting information, and licensees may
request that it be withheld as defined by 10 CFR 2.390. Each person who is to receive a copy of
the report must be verified as a qualified recipient before distribution. Licensees should confirm
the address before sending documents to the NMMSS or other recipients. In addition, they
should formally provide classification guidance to the NMMSS after a decision to classify,
declassify, or make any change in previously submitted guidance. When submitting Safeguards
Information, licensees should also submit a Concise Note Form 740M stating that the
submission is Safeguards Information and should be handled in accordance with 10 CFR 73.21,
"Requirements for the Protection of Safeguards Information."
Licensees should distribute the completed report as follows:
Submit one copy of the completed report and all supporting subschedules and lists to the
NMMSS. All RIS holders are encouraged to review their RIS information yearly and
notify the NMMSS that the data are correct or make changes.
Retain one copy for licensee files.
1.5 Reconciliation
Every reporting period, a reconciliation shall be performed between the data the licensee has
reported to the NMMSS and the projected balances that.the NMMSS has developed. The
NMMSS operator provides reports of generated balances. This process shall be considered
complete when the licensee resolves any differences between the reported and the generated
balances, including those listed for foreign obligated materials. The reconciliation should be
completed within 30 calendar days of when the licensee was notified of the discrepancy, and it
should include all accounts held by the licensee, including holding accounts.
Facilities should ensure that their weight totals in DOE/NRC Form 742C equal the weight totals
NUREG/BR-0007, Rev. 6

in DOE/NRC Form 742 for each material type. The totals in DOE/NRC Form 742C should be an
arithmetic sum of the weights listed on the batch data lines of DOE/NRC Form 742C. Generally,
the totals on DOE/NRC Forms 742 and 742C should agree with the values maintained and used
at the site. However, if reported DOE/NRC Form 742 and 742C values differ from sitemaintained values because of such issues as rounding because of different units of
measurement/reporting, then the site should submit a concise note explaining the difference.

NUREG/BR-0007, Rev. 6

2 INSTRUCTIONS FOR COMPLETING DOE/NRC FORM 742,
"MATERIAL BALANCE REPORT"
Licensees should complete DOE/NRC Form 742 in accordance with the instructions in this

NUREG/BR-0007, Rev. 6

2.1 Section A, "Material Accountability"
PROCESS CODE-Enter process code A, C, or D; use process codes C and D to modify report
data for only the current processing period:
A refers to the initial entry of data.
C refers to the replacement of data. Data may be replaced at any time before the close
of the processing period in which the initial entry was made.
D refers to the deletion of data. Data may be deleted at any time before the close of the
processing period in which the initial entry was made.
Reported material balance reports may be modified for the current processing periods. Use
process code C for replacement and D for deletion:
Submit a form with the RIS, report period, material type, sequence number, and process
code C with the unique identifier for the line to be replaced.
Submit a form with the RIS, report period, material type, sequence number, and process
code D with the unique identifier for the line to be deleted.
Submit a form with the RIS, report period, material type with no sequence number, and
process code D to delete all matching records.
Submit a form with the RIS, report period, and process code D to delete the entire

the nearest kilogram.
Optionally, if using XML format, source material may be reported to three decimal places;
however, both shipper and receiver must report to the same decimal place. If reporting to three
decimal places, the reporting unit is to the nearest thousandth of a kilogram. For example, both
the shipper and receiver may report 1655 grams as 1.655 kilograms. However, for consistency,
the licensee must continue to report to the same decimal place for that material type. If at any
time during the stated material balance period, source material has been reported to the third
decimal on a transaction, the corresponding material balance report must be reported to the
Round up fractions of 0.5 or greater. If the quantity to be entered is less than 0.5 of the reporting unit,
round down to the next whole reporting unit.

73.

FISSION AND TRANSMUTATION-Enter the calculated quantities of SNM lost by
fission and transmutation in a reactor.

74.

NORMAL OPERATIONAL LOSSES/MEASURED DISCARDS-Normal operational
losses and measured discards are material that has been discarded, whether in the form
of solids, liquids, or gases, as determined by measurement or by estimate on the basis of
measurement.
All material that leaves the inventory through the process of normal operational
losses/measured discards must be accounted for on a DOE/NRC Form 741 (if not
previously reported in the period covered by this report). To account for these discards,
use the established RIS types described below.
If the discard is to a lagoon or pond, append an L to the receiver's RIS. Measured
discards to the atmosphere or ground should be documented as an onsite transfer with
the licensee RIS as shipper and receiver. If the material goes off the inventory into a
holding area (refer to the term "holding account" in the glossary in Appendix D) for later
removal to a burial site, append an H to the receiver's RIS. When the material is
eventually shipped to a burial site, the transfer series on the DOE/NRC Form 741 will
show the shipper's RIS with an H appended and the appropriate V-series RIS in the
receiver's block. Alternatively, the licensee may return the material from the holding
account to the primary RIS and then ship the material from the primary RIS. Such
activities must also be documented on DOE/NRC Form 741. Remove discards from
inventory only when the material has been disposed of (a) by transfer to an authorized
recipient or holding area as provided in the regulations in 10 CFR Part 40, "Domestic
Licensing of Source Material," or 10 CFR Part 74, (b) as authorized pursuant to
10 CFR 20.2002, "Method for Obtaining Approval of Proposed Disposal Procedures,"
(c) as provided in 10 CFR 20.2003, "Disposal by Release into Sanitary Sewerage,"
10 CFR 20.2004, "Treatment or Disposal by Incineration," or 10 CFR 20.1302,
"Compliance with Dose Limits for Individual Members of the Public" (related to
concentrations in effluents to unrestricted areas), or (d) as provided in corresponding
Agreement State regulations. Note that the establishment of L or H accounts requires
prior NRC approval.

75.

ACCIDENTAL LOSSES-Accidental loss is the irretrievable and inadvertent loss of a
known quantity of SNM or source material as the result of an operational accident, as
determined by measurement or by estimate on the basis of measurement.

76.

APPROVED WRITE-OFFS-Leave blank.

77.

INVENTORY DIFFERENCE-Inventory difference (ID) is the difference between
physical inventory and book inventory after the book has been adjusted for all receipts
and removals. A negative entry reports a gain. A positive entry reports a loss.

NUREG/BR-0007, Rev. 6

Reactors should not report an ID to the NMMSS. At the time of physical inventory, the
value assigned to an SNM item (e.g., assembly, rod, fragment, sealed container) should
be recorded identically on both the book inventory and the physical inventory. At a
reactor, unlike at facilities that process SNM for some end use, adjustments to the values
assigned to items (representing factors such as nuclear loss, decay, and production
rounding) are explainable and should be reported as such.
80.

ENDING INVENTORY-U.S. GOVT-OWNED-Enter the ending inventory that is owned
by the U.S. Government as of the end of the last day of the period covered by this report.

81.

ENDING INVENTORY-NOT U.S. GOVT-OWNED-Enter the ending inventory that is
not owned by the U.S. Government as of the last day of the period covered by this report.

82.

TOTAL-Enter the sums of lines 41 through 81. The totals reported on this line must
agree with those on line 40.

83.

BIAS ADJUSTMENT-The ID bias adjustment is that quantity of material that should be
added to or subtracted from the ID quantity on line 77 to produce the best estimate of an
unbiased ID. The adjustment represents the algebraic summation of the impact of
measurement system biases on each component of the measured plant material
balance. Include on this line the sum of the bias adjustments for the ID for the current
period. This line should also include any prior period adjustments. Do not include bias
adjustments that have already been applied to the source data in the material balance
equation.
Note that the total ending inventories must match the total inventory reported on
DOE/NRC Form 742C for a material type.

2.2 Section B, "Foreign Obligations"
The total amount of obligated nuclear material on hand as of the end of the reporting period
must be accounted for by material type. It may not exceed the physical inventory.
The following column entries are required:
1.

COUNTRY OF OBLIGATION-Enter the unique obligated code for each category of
nuclear material. Appendix C lists the codes. The NMMSS operator can provide an
updated listing.

exceed the total element and isotope weight reported on line 82.

2.3 Section C. "Certification"
SIGNATURE, TITLE, AND DATE-An authorized representative of the licensee shall sign the
report, if submitted as a hard copy. If submitted electronically, each licensee must establish
internal procedures to ensure that the information provided in the report is accurate and that only
the authorized licensee personnel have prepared and issued the report.

NUREG/BR-0007, Rev. 6

3 INSTRUCTIONS FOR COMPLETING DOE/NRC FORM 742C,
"PHYSICAL INVENTORY LISTING"
DOE/NRC Form 742C describes the status of the nuclear material reported on lines 80 and 81
of DOE/NRC Form 742, as of the end of the reporting period. There are two separate sets of
procedures for filing DOE/NRC Form 742C, one for licensees required to report pursuant to
10 CFR 74.13, "Material Status Reports," or 10 CFR 150.17 and the other for licensees required
to report under 10 CFR Part 75.
The instructions for completing the form are presented separately for the two categories of
licensees.
3.1

Licensees Reporting Under 10 CFR 74.13 or 10 CFR 150.17

The following numbered instructions correspond to the numbered blocks or lines to be
completed by licensees on DOE/NRC Form 742C. Source material with no foreign obligation
and that is not used in enrichment services, downblending of uranium that has an initial

APPENDIX D
GLOSSARY

NUREG/BR-0007, Rev. 6

GLOSSARY
Accountability-The determination of, and current record maintenance of, special nuclear
material 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-A State that has signed an agreement with the U.S. Nuclear Regulatory
Commission under which the State regulates the use of byproduct, source, and small quantities
of special nuclear material in that State.
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, in free text format, by facilities engaged in the import and/or export of nuclear
materials, by facilities selected under the provisions of the agreement between the United States
and the International Atomic Energy Agency (IAEA) for the application of safeguards in the
U.S./IAEA Safeguards Agreement, any facility that would like to transmit any additional
explanatory nuclear material information.
EURA TOM-As of January 2008, an organization consisting of member countries Austria,
Belgium, Bulgaria, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany,
Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Poland,
Portugal, Romania, the Slovak Republic, Slovenia, Spain, Sweden, and the United Kingdom.
Foreign obligatednuclear material-Source material or special nuclear material that 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 enricheduranium (HEU)-Uranium enriched to 20 percent or greater in the isotope
uranium-235.
Holding account-Typically identified by four-character reporting identification symbols (RISs)
ending in the letter H assigned by the U.S. Nuclear Regulatory Commission. Some enrichment
facilities have holding accounts identified by three-character RISs beginning with the letter V.
Regardless of the RIS, these accounts usually acquired inventory from the shipment of licensed
material from the primary RIS in use at the licensee. Typically, a small number of licensees
have used these accounts for nuclear materials not expected to be immediately processed,
reprocessed, or disposed. However the licensed nuclear materials in holding accounts are still
in the licensee's possession and must be included in inventories reported to the Nuclear
Materials Management and Safeguards System.
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 (El) 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:
D-1

NUREG/BR-0007, Rev. 6

ID = (BI + A - R) - El
where (BI + A - R) is the book inventory.
Inventory reconciliation-Theadjustment 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 inventory difference (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.
Materialbalanceperiod-The time span to which a material or physical inventory pertains.
Nuclear MaterialsManagement 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 the U.S. Department of Energy and the
U.S. Nuclear Regulatory Commission and those licensees they regulate. The system is used to
satisfy the nuclear materials information requirements of agreements between the United States
and foreign entities. In addition, the system provides the reporting interface between facilities
selected under the provisions of the U.S./International Atomic Energy Agency 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 special nuclear material.
Report Period-Period inclusive of defined dates (e.g., October 1, 2005, through September 30,
2006). Reports for a reporting period, such as inventory, material balance, and related
transactions reports, must assure that no dates are undocumented between the previous and
current submittals.
Reporting identificationsymbol (RIS)-A unique combination of three or four letters that is
assigned to each reporting organization by the U.S. Nuclear Regulatory Commission for the
purpose of identification in the Nuclear Materials Management and Safeguards System
database.
Shipper-receiverdifference-The difference between what a shipper claims a shipment of
special nuclear material contained and what the receiver claims it received, where both the
shipper's and receiver's values are based on measurement.
NUREG/BR-0007, Rev. 6

D-2

Source material-Uranium or thorium, or any combination thereof, in any physical or chemical
form; or ores that contain by weight 0.05 percent or more of uranium, thorium, or any
combination thereof. Source material does not include special nuclear material.
Special nuclearmaterial (SNM)-Plutonium, uranium-233, and uranium enriched in the
isotope 233 or 235.
U.S. Government owned-Nuclear material that, while used by a licensee as part of its activities,
is actually an asset owned by a Federal government agency such as the U.S. Department of
Energy (DOE). These materials may be bulk materials, discrete radiation sources, or finished
products. Such materials may represent a lease or loan arrangement with a Government
agency. U.S. Government-owned materials are typically represented by an owner code of G on
shipping information (i.e., DOE/U.S. Nuclear Regulatory Commission (NRC) Form 741) and
inventory documentation (i.e., DOE/NRC Forms 742 and 742C). One way a licensee determine
whether nuclear material in its possession is U.S. Government owned is to review the licensee's
DOE/NRC Form 741 documentation listing the original receipt of the material. If such material is
U.S. Government owned, it will have an owner code of G entered on the licensee's portion of the
form.
