SECTION 1: INTRODUCTION
`

Background
The United States signed an Additional Protocol (AP) to the Agreement Between the United
States of America and the International Atomic Energy Agency (IAEA) for the Application of
Safeguards in the United States, which requires reporting of certain aspects of the U.S. nuclear
fuel cycle, including: buildings on the sites of certain nuclear facilities; mining and
concentration of nuclear ores; nuclear-related equipment manufacturing, assembly, or
construction; imports and exports of specified nuclear equipment and non-nuclear material;
imports, exports, and other activities involving certain source material (i.e., source material that
has not reached the composition and purity suitable for fuel fabrication or for being isotopically
enriched); certain nuclear fuel cycle-related research and development activities not involving
nuclear material; and other activities involving nuclear material not currently subject to the U.S.IAEA Safeguards Agreement. The requirements of the AP are promulgated in the Department of
Commerce (DOC) Additional Protocol Regulations (APR) – Title 15 of the U.S. Code of Federal
Regulations (15 CFR) Parts 781 – 799 and Nuclear Regulatory Commission (NRC) US-IAEA
Safeguards Agreement Regulations -- 10 CFR Parts 75 and 110. The DOC Bureau of Industry
and Security (BIS) operates the national database and will collect reports from NRC- and DOCregulated persons.

Handbook Overview
This Report Handbook for Sites should be used in conjunction with 10 CFR Parts 75 and 110 to
complete DOC/NRC Forms AP-A through AP-Q. Sites of IAEA-Selected Facilities are required
(by the NRC) to complete these forms and submit them to BIS. IAEA-Selected Facilities are
nuclear facilities which the IAEA has selected from the U.S. Eligible Facilities List and for
which the U.S. government has submitted a Design Information Questionnaire (DIQ) to the
IAEA under the U.S.-IAEA Safeguards Agreement (INFCIRC/288). These facilities will
complete the report forms in this Handbook rather than the report forms included in the Report
Handbook for Locations.
Section 2 of this Handbook provides a brief overview of anticipated reporting requirements for
sites of IAEA-Selected Facilities. A flow chart is provided to assist in understanding the
requirements for the different types of reports. Table 1, “Deadlines for Submission of Reports
and Amendments,” lists the different types of reports, the forms to be included in each report,
and the deadlines for submission of these reports to BIS.
Section 3 of the Handbook provides all of the report forms with detailed instructions for
completing each form on the reverse side of the form. The number of forms each site submits
will depend on the type of report being submitted and the activities that are relevant to the
reporting site. Based on the type of report being submitted, each site of an IAEA-Selected
Facility will be required to submit Forms AP-A and AP-B, and a separate Form AP-C for each
building on the site, and the relevant activity-based forms that are applicable for the site. For
example, a site with a building that manufactures zirconium tubes would submit Forms AP-A,
AP-B, a separate Form AP-C for the building, and Form AP-F).
2

There are also three supplements to this Handbook.
Supplement 1 is a Glossary of Definitions and Terms and serves to define key words that
are used in the Handbook as well as in the report forms.
Supplement 2 provides a list of the Nuclear Fuel Cycle-Related Manufacturing,
Assembly and Construction Activities that are reported on Form AP-F. These activities
and related definitions are defined in further detail in Supplement 2 of this Handbook.
Supplement 3 provides a detailed List of Specified Equipment and Non-Nuclear Material,
for the reporting of Exports (AP-M) and Imports (AP-N).

Paperwork Reduction Act
Notwithstanding any other provision of law, no person is required to, nor shall any person be
subject to a penalty for failure to comply with a collection of information, subject to the
Paperwork Reduction Act (PRA), unless that collection of information displays a currently valid
OMB Control Number. This rule proposes a collection of information subject to the
requirements of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). The
information collection contained in this rule is part of a joint information collection by the
Bureau of Industry and Security (BIS), in accordance with the Additional Protocol Regulations
(APR) (15 CFR Parts 781-799), and the Nuclear Regulatory Commission (NRC), in accordance
with amendments to its regulations in 10 CFR Part 75 and 10 CFR Part 110. BIS has submitted
this proposed collection to the Office of Management and Budget for approval. A total of
approximately 549 respondents are expected to be subject to the information collection
requirements set forth in these BIS and NRC rules. These information collection requirements
are expected to involve an estimated 920 total burden hours per annum at a total estimated cost
of $5,865 per annum.
BIS will use the information contained in reports submitted by U.S. persons to compile the U.S.
Declaration as required by the Additional Protocol.

Forms
Report forms required by the APR may be downloaded from the Internet at www.ap.gov. You
also may obtain these forms by contacting: Treaty Compliance Division, Bureau of Industry and
Security, U.S. Department of Commerce, Attn: Forms Request, 14th Street and
Pennsylvania Avenue, N.W., Room 2705, Washington, DC 20230, Telephone: (202)
482-1001.

Report Types
The following types of reports may be required:
INITIAL REPORT:
You must submit an Initial Report to BIS by January 31st, if you commenced nuclear fuel cyclerelated activities during the previous calendar year, and have not previously reported activities to
BIS.
ANNUAL REPORTING:
You must submit either an ANNUAL UPDATE REPORT or a NO CHANGES REPORT by
January 31st, if, at any time during the previous calendar year, you continued to engage in
nuclear fuel cycle-related activities at a site for which you submitted an Initial Report.
ANNUAL UPDATE REPORT:
You must submit an Annual Update Report (DOC/NRC Forms AP-A, AP-B, AP-C and
required activity forms) by January 31st if you have updates or changes to report
concerning your site or your site’s activities during the previous calendar year. When
preparing the Annual Update Report, you must complete the same report forms that you
used for submitting your Initial Report on these activities. Additional report forms will
be required if your site engaged in any new reportable activities
NO CHANGES REPORT:
If all of the information, including contact information and other administrative
information on AP-A and AP-B, provided in your most recently submitted report has not
changed, you may submit a No Changes Report (Form AP-Q) in lieu of an Annual
Update Report.
AMENDED REPORT:
Changes to previously submitted information must be submitted on an Amended Report.
Corrections to information regarding a reportable activity and corrections or changes to
company information (e.g., corrections to address, changes in contact information, etc.)
must be submitted using the same AP Forms used previously and the corrections must be
submitted within 30 calendar days after the information has changed or the error
identified. Amendments to previously reported information resulting from an IAEA
complementary access must be submitted using the same AP Forms used previously and
the corrections must be submitted within 30 calendar days after the date of the
complementary access. Any amended AP Forms should be accompanied with a cover
letter addressing the specific change made. If additional information is requested during
a complementary access, beyond what is submitted as part of the annual update, Form
AP-O should be used unless a preferred alternative is agree upon by either the
Department of Commerce or the Nuclear Regulatory Commission.

SUPPLEMENT 3: LIST OF SPECIFIED EQUIPMENT AND NON-NUCLEAR MATERIAL FOR THE
REPORTING OF EXPORTS AND IMPORTS
1.

Reactors and equipment therefor

1.1

Complete nuclear reactors
Nuclear reactors capable of operation so as to maintain a controlled self-sustaining fission chain reaction,
excluding zero energy reactors, the latter being defines as reactors with a designed maximum rate of
production of plutonium not exceeding 100 grams per year.
EXPLANATORY NOTE
A “nuclear reactor” basically includes the items within or attached directly to the reactor vessel, the
equipment which controls the level of power in the core, and the components which normally contain or
come in direct contact with or control the primary coolant of the reactor core. It is not intended to exclude
reactors which could reasonably be capable of modification to produce significantly more than 100 grams
of plutonium per year. Reactors designed for sustained operation at significant power levels, regardless of
their capacity for plutonium production, are not considered as “zero energy reactors”.

1.2

Reactor pressure vessels
Metal vessels, as complete units or as major shop-fabricated parts therefor, which are especially designed
or prepared to contain the core of a nuclear reactor as defined in paragraph 1.1 above and are capable of
withstanding the operating pressure of the primary coolant.
EXPLANATORY NOTE
A tope plate for a reactor pressure vessel is covered by item 1.2 as a major shop-fabricated part of a
pressure vessel. Reactor internals (e.g. support columns and plates for the core and other vessel internals,
control rod guide tubes, thermal shields, baffles, core grid plates, diffuser plates, etc.) are normally supplied
by the reactor supplier. In some cases, certain internal support components are included in the fabrication
of the pressure vessel. These items are sufficiently critical to the safety and reliability of the operation of
the reactor (and, therefore, to the guarantees and liability of the reactor supplier), so that their supply,
outside the basic supply arrangement for the reactor itself, would not be common practice. Therefore,
although the separate supply of these unique, especially designed and prepared, critical, large, and
expensive items would not necessarily be considered as falling outside the area of concern, such a mode of
supply is considered unlikely.

1.3

Reactor fuel charging and discharging machines
Manipulative equipment especially designed or prepared for inserting or removing fuel in a nuclear reactor
as defined in paragraph 1.1 above capable of on-load operation or employing technically sophisticated
positioning or alignment features to allow complex off-load fueling operations such as those in which direct
viewing of or access to the fuel is not normally available.

1.4

Reactor control rods
Rods especially designed or prepared for the control of the reaction rate in a nuclear reactor as defined in
paragraph 1.1 above.
EXPLANATORY NOTE
This item includes, in addition to the neutron absorbing part, the support or suspension structures therefor if
supplied separately.

1.5

Reactor pressure tubes
Tubes which are especially designed or prepared to contain fuel elements and the primary coolant in a
reactor as defined in paragraph 1.1 above at an operating pressure in excess of 5.1 MPa (740 psi).

1.6

Zirconium tubes
Zirconium metal and alloys in the form of tubes or assemblies of tubes, and in quantities exceeding 500 kg
in any period of 12 months, especially designed or prepare for use in a reactor as defined in paragraph 1.1
above, and in which the relation of hafnium to zirconium is less than 1:500 parts by weight.

1.7

Primary coolant pumps
Pumps especially designed or prepared for circulating the primary coolant for nuclear reactors as defined in
paragraph 1.1 above.
EXPLANATORY NOTE
Especially designed or prepared pumps may include elaborate sealed or multi-sealed systems to prevent
leakage of primary coolant, canned-driven pumps, and pumps with inertial mass systems. This definition
encompasses pumps certified to NC-1 or equivalent standards.

2.

Non-nuclear materials for reactors

2.1

Deuterium and heavy water
Deuterium, heavy water (deuterium oxide) and any other deuterium compound in which the ratio of
deuterium to hydrogen atoms exceeds 1:5000 for use in a nuclear reactor as defined in paragraph 1.1 above
in quantities exceeding 200 kg of deuterium atoms for any one recipient country in any period of 12
months.

2.2

Nuclear grade graphite
Graphite having a purity level better than 5 parts per million boron equivalent and with a density greater
than 1.50 g/cm3 for use in a nuclear reactor as defined in paragraph 1.1 above in quantities exceeding 3 x
104 kg (30 metric tons) for any one recipient country in any period of 12 months.
NOTE
For the purpose of reporting, the Government will determine whether or not the exports of graphite meeting
the above specifications are for nuclear reactor use.

3.

Plants for the reprocessing of irradiated fuel elements, and equipment especially designed or
prepared therefor
INTRODUCTORY NOTE
Reprocessing irradiated nuclear fuel separates plutonium and uranium from intensely radioactive fission
products and other transuranic elements. Different technical processes can accomplish this separation.
However, over the years Purex has become the most commonly used and accepted process. Purex involves
the dissolution of irradiated nuclear fuel in nitric acid, followed by separation of the uranium, plutonium,
and fission products by solvent extraction using a mixture of tributyl phosphate in an organic diluent.
Purex facilities have process functions similar to each other, including: irradiated fuel element chopping,
fuel dissolution, solvent extraction, and process liquor storage. There may also be equipment for thermal
denitration of uranium nitrate, conversion of plutonium nitrate to oxide or metal, and treatment of fission
product waste liquor to a form suitable for long term storage or disposal. However the specific type and
configuration of the equipment performing these functions may differ between Purex facilities for several
reasons, including the type and quantity of irradiated nuclear fuel to be reprocessed and the intended
disposition of the recovered materials, and the safety and maintenance philosophy incorporated into the
design of the facility. A “plant for the reprocessing of irradiated fuel elements” includes the equipment and
components which normally come in direct contact with and directly control the irradiated fuel and the
major nuclear material and fission product processing streams. These processes, including the complete
systems for plutonium conversion and plutonium metal production, may be identified by the measures
taken to avoid criticality (e.g. by geometry), radiation exposure (e.g. by shielding), and toxicity hazards
(e.g. by containment). Items of equipment that are considered to fall within the meaning of the phrase “and
equipment especially designed or prepared” for the reprocessing of irradiated fuel elements include:

3.1

Irradiated fuel element chopping machines
INTRODUCTORY NOTE
This equipment breaches the cladding of the fuel to expose the irradiated nuclear material to dissolution.
Especially designed metal cutting shears are the most commonly employed, although advanced equipment,
such as lasers, may be used. Remotely operated equipment especially designed or prepared for use in a
reprocessing plant as identified above and intended to cut, chop or shear irradiated nuclear fuel assemblies,
bundles or rods.

3.2

Dissolvers
INTRODUCTORY NOTE
Dissolvers normally receive the chopped-up spent fuel. In these critically safe vessels, the irradiated
nuclear material is dissolved in nitric acid and the remaining hulls removed from the process stream.
Critically safe tanks (e.g. small diameter, annular or slab tanks) especially designed or prepared for use in a
reprocessing plant as identified above, intended for dissolution of irradiated nuclear fuel and which are
capable of withstanding hot, highly corrosive liquid, and which can be remotely loaded and maintained.

3.3

Solvent extractors and solvent extraction equipment
INTRODUCTORY NOTE
Solvent extractors both receive the solution of irradiated fuel from the dissolvers and the organic solution
which separates the uranium, plutonium, and fission products. Solvent extraction equipment is normally
designed to meet strict operating parameters, such as long operating lifetimes with no maintenance
requirements or adaptability to easy replacement, simplicity of operation and control, and flexibility for
variations in process conditions. Especially designed or prepared solvent extractors such as packed or
pulse columns, mixer settlers or centrifugal contactors for use in a plant for the reprocessing of irradiated
fuel. Solvent extractors must be resistant to the corrosive effect of nitric acid. Solvent extractors are
normally fabricated to extremely high standards (including special welding and inspection and quality
assurance and quality control techniques) out of low carbon stainless steels, titanium, zirconium, or other
high quality materials.

3.4

Chemical holding or storage vessels
INTRODUCTORY NOTE
Three main process liquor streams result from the solvent extraction step. Holding or storage vessels are
used in the further processing of all three streams, as follows:
(a)

The pure uranium nitrate solution is concentrated by evaporation and passed to a denitration
process where it is converted to uranium oxide. This oxide is re-used in the nuclear fuel cycle.

(b)

The intensely radioactive fission products solution is normally concentrated by evaporation and
stored as a liquor concentrate. This concentrate may be subsequently evaporated and converted to
a form suitable for storage or disposal.

(c)

The pure plutonium nitrate solution is concentrated and stored pending its transfer to further
process steps. In particular, holding or storage vessels for plutonium solutions are designed to
avoid criticality problems resulting from changes in concentration and form of this stream.

Especially designed or prepared holding or storage vessels for use in a plant for the reprocessing of
irradiated fuel. The holding or storage vessels must be resistant to the corrosive effect of nitric acid. The
holding or storage vessels are normally fabricated of materials such as low carbon stainless steels, titanium
or zirconium, or other high quality materials. Holding or storage vessels may be designed for remote
operation and maintenance and may have the following features for control of nuclear criticality:
(1)
walls or internal structures with a boron equivalent of at least two percent, or
(2)
a maximum diameter of 175 mm (7 in) for cylindrical vessels, or

(3)
3.5

a maximum width of 75 mm (3 in) for either a slab or annular vessel.

Plutonium nitrate to oxide conversion system
INTRODUCTORY NOTE
In most reprocessing facilities, this final process involves the conversion of the plutonium nitrate solution
to plutonium dioxide. The main functions involved in this process are: process feed storage and
adjustment, precipitation and solid-liquor separation, calcination, product handling, ventilation, waste
management, and process control. Complete systems especially designed or prepared for the conversion of
plutonium nitrate to plutonium oxide, in particular adapted so as to avoid criticality and radiation effects
and to minimize toxicity hazards.

3.6

Plutonium oxide to metal production system
INTRODUCTORY NOTE
This process, which could be related to a reprocessing facility, involves the fluorination of plutonium
dioxide, normally with highly corrosive hydrogen fluoride, to produce plutonium fluoride which is
subsequently reduced using high purity calcium metal to produce metallic plutonium and a calcium fluoride
slag. The main functions involved in this process are: fluorination (e.g. involving equipment fabricated or
lined with a precious metal), metal reduction (e.g. employing ceramic crucibles), slag recover, product
handling, ventilation, waste management and process control. Complete systems especially designed or
prepared for the production of plutonium metal, in particular adapted so as to avoid criticality and radiation
effects and to minimize toxicity hazards.

4.

Plants for the fabrication of fuel elements
A “plant for the fabrication of fuel elements” includes the equipment:
(a)

Which normally comes in direct contact with, or directly processes, or controls, the production
flow of nuclear material, or

(b)

Which seals the nuclear material within the cladding.

5.

Plants for the separation of isotopes of uranium and equipment, other than analytical instruments,
especially designed or prepared therefor
Items of equipment that are considered to fall within the meaning of the phrase “equipment, other than
analytical instruments, especially designed or prepared” for the separation of isotopes of uranium include:

5.1

Gas centrifuges and assemblies and components especially designed or prepared for use in gas
centrifuges
INTRODUCTORY NOTE
The gas centrifuge normally consists of a thin-walled cylinder(s) of between 75 mm (3 in.) and 400 mm
(16.in.) diameter contained in a vacuum environment and spun at high peripheral speed of the order of 300
m/s or more with its central axis vertical. In order to achieve high speed the materials of construction for
the rotating components have to be of a high strength to density ratio and the rotor assembly, and hence its
individual components, have to be manufactured to very close tolerances in order to minimize the
unbalance. In contrast to other centrifuges, the gas centrifuge for uranium enrichment is characterized by
having within the rotor chamber a rotating disc-shaped baffle(s) and a stationary tube arrangement for
feeding and extracting the UF6 gas and featuring at least 3 separate channels, of which 2 are connected to
scoops extending from the rotor axis towards the periphery of the rotor chamber. Also contained within the
vacuum environment are a number of critical items which do not rotate and which although they are
especially designed are not difficult to fabricate nor are they fabricated out of unique materials. A
centrifuge facility however requires a large number of these components, so that quantities can provide an
important indication of end use.

5.1.1

Rotating components

(a)

Complete rotor assemblies:

Thin-walled cylinders, or a number of interconnected thin-walled cylinders, manufactured from one or
more of the high strength to density ratio materials described in the EXPLANATORY NOTE to this

(see EXPLANATORY NOTE to Section 5.2). The magnet couples with a pole piece or a second magnet

fitted to the top cap described in Section 5.1.1(e). The magnet may be ring-shaped with a relation between
outer and inner diameter smaller or equal to 1.6:1. The magnet may be in a form having an initial
permeability of 0.15H/m (120,000 in CGS units) or more, or a remanence of 98.5% or more, or an energy
product of greater than 80kJ/m3 (107 gauss-oersteds). In addition to the usual material properties, it is a
prerequisite that the deviation of the magnetic axes from the geometrical axes is limited to very small

called for.
(b)

Bearings/Dampers:

Especially designed or prepared bearing comprising a pivot/cup assembly mounted on a damper. The pivot
is normally a hardened steel shaft with a hemisphere at one end with a means of attachment to the bottom

comprised of thin layers typically 2.0 mm (0.08 in.) thick or less.
(e)

being fixed to the central gas extraction system. The tubes are made of or protected by materials resistant
to corrosion by UF6.
5.2

Especially designed or prepared auxiliary systems, equipment and components for gas centrifuge
enrichment plants
INTRODUCTORY NOTE
The auxiliary systems, equipment and components for a gas centrifuge enrichment plant are the systems of
plant needed to feed UF6 to the centrifuges, to link the individual centrifuges to each other to form cascades
(or stages) to allow for progressively higher enrichments and to extract the ‘product’ and ‘tails’ UF 6 from
the centrifuges, together with the equipment required to drive the centrifuges or to control the plant.
Normally UF6 is evaporated from the solid using heated autoclaves and is distributed in gaseous form to the

centrifuges by way of cascade header pipework. The ‘product’ and ‘tails’ UF 6 gaseous streams flowing
from the centrifuges are also passed by way of cascade header pipework to cold traps (operating at about
203 K 9-70NC)) where they are condensed prior to onward transfer into suitable containers for
transportation or storage. Because an enrichment plant consists of many thousands of centrifuges arranged
in cascades there are many kilometers of cascade header pipework, incorporating thousands of welds with a
substantial amount of repetition of layout. The equipment, components and piping systems are fabricated
to very high vacuum and cleanliness standards.
5.2.1

Feed systems/product and tails withdrawal systems
Especially designed or prepared process systems including:
Feed autoclaves (or stations), used for passing UF6 to the centrifuge cascades at up to 100 kPa
(15 psi) and at a rate of 1 kg/h or more;
Desublimers (or cold traps) used to remove UF 6 from the cascades at up to 3 kPa (0.5 psi)
pressure. The desublimers are capable of being chilled to 203 K (-70NC) and heated to 343 K
(70NC);
‘Product’ and ‘Tails’ stations used for trapping UF6 into containers.
This plant, equipment and pipework is wholly made of or lined with UF6-resistant materials (see
EXPLANATORY NOTE to this section) and is fabricated to very high vacuum and cleanliness standards.

5.2.2

Machine header piping systems
Especially designed or prepared piping systems and header systems for handling UF 6 within the centrifuge
cascades. The piping network is normally of the ‘triple’ header system with each centrifuge connected to
each of the headers. There is thus a substantial amount of repetition in its form. It is wholly made of UF 6resistant materials (see EXPLANATORY NOTE to this section) and is fabricated to very high vacuum and
cleanliness standards.

5.2.3

UF6 mass spectrometers/ion sources
Especially designed or prepared magnetic or quadrupole mass spectrometers capable of taking ‘on-line’
samples of feed, product or tails, from UF6 gas streams and having all of the following characteristics:

5.3

Especially designed or prepared assemblies and components for use in gaseous diffusion enrichment
INTRODUCTORY NOTE
In the gaseous diffusion method of uranium isotope separation, the main technological assembly is a
special porous gaseous diffusion barrier, heat exchanger for cooling the gas (which is heated by the process
of compression), seal valves and control valves, and pipelines. Inasmuch as gaseous diffusion technology
uses uranium hexafluoride (UF6), all equipment, pipeline and instrumentation surfaces (that come in
contact with the gas) must be made of materials that remain stable in contact with UF6. A gaseous
diffusion facility requires a number of these assemblies, so that quantities can provide an important
indication of end use.

5.4

Especially designed or prepared auxiliary systems, equipment and components for use in gaseous
diffusion enrichment

INTRODUCTORY NOTE
The auxiliary systems, equipment and components for gaseous diffusion enrichment plants are the systems
of plant needed to feed UF6 to the gaseous diffusion assembly, to link the individual assemblies to each
other to form cascades (or stages) to allow for progressively higher enrichments and to extract the ‘product’
and ‘tails’ UF6 from the diffusion cascades. Because of the high inertial properties of diffusion cascades,
any interruption in their operation, and especially their shut-down, leads to serious consequences.
Therefore, a strict and constant maintenance of vacuum in all technological systems, automatic protection
from accidents, and precise automated regulation of the gas flow is of importance in a gaseous diffusion
plant. All this leads to a need to equip the plant with a large number of special measuring, regulating and
controlling systems. Normally UF6 is evaporated from cylinders placed within autoclave and is distributed
in gaseous form to the entry point by way of cascade header pipework. The ‘product’ and ‘tails’ UF 6
gaseous streams flowing from exit points are passed by way of cascade header pipework to either cold traps
or to compression stations where the UF6 gas is liquefied prior to onward transfer into suitable containers
for transportation or storage. Because a gaseous diffusion enrichment plant consists of a large number of
gaseous diffusion assemblies arranged in cascades, there are many kilometers of cascade header pipework,
incorporating thousands of welds with substantial amounts of repetition layout. The equipment,
components and piping systems are fabricated to very high vacuum and cleanliness standards.

Especially designed or prepared systems, equipment and components for use in aerodynamic

INTRODUCTORY NOTE
In aerodynamic enrichment processes, a mixture of gaseous UF 6 and light gas (hydrogen or helium) is
compressed and then passed through separating elements wherein isotopic separation is accomplished by
the generation of high centrifugal forces over a curved-wall geometry. Two processes of this type have
been successfully developed: the separation nozzle process and the vortex tube process. For both processes
the main components of a separation stage include cylindrical vessels housing the special separation
elements (nozzles or vortex tubes), gas compressors and heat exchangers to remove the heat of
compression. An aerodynamic plant requires a number of these stages, so that quantities can provide an
important indication of end use. Since aerodynamic processes use UF 6, all equipment, pipeline and
instrumentation surfaces (that come in contact with the gas) must be made of materials that remain stable in
contact with UF6.
EXPLANATORY NOTE

Especially designed or prepared systems, equipment and components for use in chemical exchange or
ion exchange enrichment plants
INTRODUCTORY NOTE
The slight difference in mass between the isotopes of uranium causes small changes in chemical reaction
equilibria that can be used as a basis for separation of the isotopes. Two processes have been successfully
developed: liquid-liquid chemical exchange and solid-liquid ion exchange. In the liquid-liquid chemical
exchange process, immiscible liquid phases (aqueous and organic) are countercurrently contacted to give
the cascading effect of thousands of separation stages. The aqueous phase consists of uranium chloride in
hydrochloric acid solution; the organic phase consists of an extractant containing uranium chloride in an
organic solvent. The contactors employed in the separation cascade can be liquid-liquid exchange columns
(such as pulsed columns with sieve plates) or liquid centrifugal contactors. Chemical conversions
(oxidation and reduction) are required at both ends of the separation cascade in order to provide for the
reflux requirements at each end. A major design concern is to avoid contamination of the process streams
with certain metal ions. Plastic, plastic-lined (including use of fluorocarbon polymers) and/or glass-lined
columns and piping are therefore used. In the solid-liquid ion-exchange process, enrichment is
accomplished by uranium adsorption/desorption on a special, very fast-acting, ion-exchange resin or
adsorbent. A solution of uranium in hydrochloric acid and other chemical agents is passed through
cylindrical enrichment columns containing packed beds of the adsorbent. For a continuous process, a
reflux system is necessary to release the uranium from the adsorbent back into the liquid flow so that
‘product’ and ‘tails’ can be collected. This is accomplished with the use of suitable reduction/oxidation
chemical agents that are fully regenerated in separate external circuits and that may be partially regenerated
within the isotopic separation columns themselves. The presence of hot concentrated hydrochloric acid
solutions in the process requires that the equipment be made of or protected by special corrosion-resistant
materials.

5.6.1

Liquid-liquid exchange columns (Chemical exchange)
Countercurrent liquid-liquid exchange columns having mechanical power input (i.e., pulsed columns with
sieve plates, reciprocating plate columns, and columns with internal turbine mixers), especially designed or

concentrated hydrochloric acid solutions, these columns and their internals are made of or protected by
suitable plastic materials (such as fluorocarbon polymers) or glass. The stage residence time of the
columns is designed to be short (30 seconds or less).
5.6.2

Liquid-liquid centrifugal contactors (Chemical exchange)
Liquid-liquid centrifugal contactors especially designed or prepared for uranium enrichment using the
chemical exchange process. Such contactors use rotation to achieve dispersion of the organic and aqueous
streams and the centrifugal force to separate the phases. Fro corrosion resistance to concentrated
hydrochloric acid solutions, the contactors are made of or are lined with suitable plastic materials (such as
fluorocarbon polymers) or are lined with glass. The stage residence time of the centrifugal contactors is
designed to be short (30 seconds or less).

5.6.3

Uranium reduction systems and equipment (Chemical exchange)

aqueous solution, evaporation and/or other equipment to accomplish solution pH adjustment and control,
and pumps or other transfer devices for feeding to the electrochemical reduction cells. A major design
concern is to avoid contamination of the aqueous stream with certain metal ions. Consequently, for those
parts in contact with the process stream, the system is constructed of equipment made of or protected by
suitable materials (such as glass, fluorocarbon polymers, polyphenyl sulfate, polyether sulfone, and resinimpregnated graphite).

INTRODUCTORY NOTE
In the electromagnetic process, uranium metal ions produced by ionization of a salt feed material (typically
UCL4) are accelerated and passed through a magnetic field that has the effect of causing the ions of

different isotopes to follow different paths. The major components of an electromagnetic isotope separator
include: a magnetic field for ion-beam diversion/separation of the isotopes, an ion source with its
acceleration system, and a collection system for the separated ions. Auxiliary systems for the process
include the magnet power supply system, the ion source high-voltage power supply system, the vacuum
system, and extensive chemical handling systems for recovery of product and cleaning/recycling of
components.

Plants for the production of heavy water, deuterium and deuterium compounds and equipment
especially designed or prepared therefor
INTRODUCTORY NOTE
Heavy water can be produced by a variety of processes. However, the two processes that have proven to be
commercially viable are the water-hydrogen sulfphide exchange process (GS process) and the ammoniahydrogen exchange process.

The GS process is based upon the exchange of hydrogen and deuterium between water and hydrogen
sulphide within a series of towers which are operated with the top section cold and the bottom section hot.
Water flows down the towers while the hydrogen sulphide gas circulates from the bottom to the top of the
towers. A series of perforated trays are used to promote mixing between the gas and the water. Deuterium
migrates to the water at low temperatures and to the hydrogen sulphide at high temperatures. Gas or water,
enriched in deuterium, is removed from the first stage towers at the junction of the hot and cold sections
and the process is repeated in subsequent stage towers. The product of the last stage, water enriched up to
30% in deuterium, is sent to a distillation unit to produce reactor grade heavy water, i.e., 99.75% deuterium
oxide.
The ammonia-hydrogen exchange process can extract deuterium from synthesis gas through contact with
liquid ammonia in the presence of a catalyst. The synthesis gas is fed into exchange towers and to an
ammonia converter. Inside the towers the gas flows from the bottom to the top while the liquid ammonia
flows form the top to the bottom. The deuterium is stripped from the hydrogen in the synthesis gas and
concentrated in the ammonia. The ammonia then flows in to an ammonia cracker at the bottom of the
tower while the gas flows into an ammonia converter at the top. Further enrichment takes place in
subsequent stages and reactor grade heavy water is produced through final distillation. The synthesis gas
feed can be provided by an ammonia plant that, in turn , can be constructed in association with a heavy
water ammonia-hydrogen exchange plant. The ammonia-hydrogen exchange process can also use ordinary
water as a feed source of deuterium.
Many of the key equipment items for heavy water production plants using GS or the ammonia-hydrogen
exchange processes are common to several segments of the chemical and petroleum industries. This is
particularly so for small plants using the GS process. However, few of the items are available “off-theshelf”. The GS and ammonia-hydrogen processes require the handling of large quantities of flammable,
corrosive and toxic fluids at elevated pressures. Accordingly, in establishing design and operating
standards for plants and equipment using these processes, careful attention to the materials selection and
specifications is required to ensure long service life with high safety and reliability factors. The choice of
scale is primarily a function of economics and need. Thus, most of the equipment items would be prepared
according to the requirements of the customer.
Finally, it should be noted that, in both the GS and the ammonia-hydrogen exchange processes, items of
equipment which individually are not especially designed or prepared for heavy water production an be
assembled into systems which are especially designed or prepared for producing heavy water. The catalyst
production system used in the ammonia-hydrogen exchange process and water distillation systems used for
the final concentration of heavy water to reactor-grade in either process are examples of such systems.
The items of equipment which are especially designed or prepared for the production of heavy water

Plants for the conversion of uranium and equipment especially designed or prepared therefor
INTRODUCTORY NOTE
Uranium conversion plants and systems may perform one or more transformations from one uranium
chemical species to another, including: conversion of uranium ore concentrates to UO 3, conversion of UO3
to UO2, conversion of uranium oxides to UF4 or UF6, conversion of UF4 to UF6, conversion of UF6 to UF4,
conversion of UF4 to uranium metal, and conversion of uranium fluorides to UO2. Many of the key
equipment items for uranium conversion plants are common to several segments of the chemical process
industry. For example, the types of equipment employed in these processes may include: furnaces, rotary
kilns, fluidized bed reactors, flame tower reactors, liquid centrifuges, distillation columns and liquid-liquid
extraction columns. However, few o t the items are available “off-the-shelf”; most would be prepared
according to the requirements and specification of the customer. In some instances, special design and
construction considerations are required to address the corrosive properties of some of the chemicals
handled (HF, F2, ClF3, and uranium fluorides). Finally, it should be noted that, in all of the uranium
conversion processes, items of equipment which individually are not especially designed or prepared for
uranium conversion can be assembled into systems which are especially designed or prepared for use in
uranium conversion.

7.1

Especially designed or prepared systems for the conversion of uranium ore concentrates to UO 3

Conversion of uranium ore concentrates to UO3 can be performed by first dissolving the ore in nitric acid
and extracting purified uranyl nitrate using a solvent such as tributyl phosphate. Next, the uranyl nitrate is
converted to UO3 either by concentration and denitration or by neutralization with gaseous ammonia to
produce ammonium diuranate with subsequent filtering, drying, and calcining.

7.2

Especially designed or prepared systems for the conversion of UO 3 to UF6
EXPLANATORY NOTE
Conversion of UO3 to UF6 can be performed directly by fluorination. The process requires a source of
fluorine gas or chlorine trifluoride.

7.3

Especially designed or prepared systems for the conversion of UO3 to UO2
EXPLANATORY NOTE
Conversion of UO3 to UO2 can be performed through reduction of UO3 with cracked ammonia gas or
hydrogen.

EXPLANATORY NOTE
Conversion of UF4 to UF6 is performed by exothermic reaction with fluorine in a tower reactor. UF 6 is
condensed from the hot effluent gases by passing the effluent stream through a cold trap cooled to -10C.
The process requires a source of fluorine gas.

7.6

ammonia is added to precipitate ammonium diuranate, and the diuranate is reduced to UO 2 with hydrogen
at 820C. In the third process, gaseous UF6, CO2, and NH3 are combined with water, precipitating
ammonium uranyl carbonate. The ammonium uranyl carbonate is combined with steam and hydrogen at
