                                 CHAPTER IV

                        NUCLEAR MATERIALS ALLOTMENTS

1.  GENERAL.  One element of the nuclear materials management program is the
    distribution of nuclear materials to user programs.  A key component of
    that activity is the nuclear materials allotment control system.

2.  ALLOTMENTS.

    a.   Terminology.  An allotment is the quantity of a nuclear material
         allocated annually to a field office for a user project for which
         the field office has been assigned program management
         responsibility by a Headquarters program.  The terms that describe
         an allotment are "withdrawals" and "returns".  Categorization of
         material transactions depends on the type of project involved in
         the transaction and whether the transaction is considered by the
         shipper or receiver of the nuclear material.

         (1)  Types of projects are: /4

              (a)  User Projects.  Projects that use nuclear materials for
                   research and development, production and nonproduction
                   reactors, and weapon production activities.

              (b)  Supply Projects.  Nonuser projects that produce, process,
                   or store nuclear materials for distribution to user
                   projects.  "E" and "M" projects are considered supply
                   projects.

              (c)  Special Projects.  Projects under the program management
                   control of the Office of Environmental Restoration and
                   Waste Management, but do not include user projects.
                   Special project materials are identified with an "I"
                   project number or other project numbers established by
                   the Office of Nuclear Weapons Management.

         (2)  Allotments are categorized as follows:

              (a)  Withdrawals.  Receipt of nuclear material by a user
                   project from a supply project.

              (b)  Returns.  Removal of nuclear material from a user project
                   to a supply project.

"Project Number-Title Index by Programmatic Field Office" identifies user,
supply, and special projects.


    b.   Issuing Allotments.  The Office of Nuclear Weapons Management will
         issue nuclear materials allotments (for materials identified in
         Figure VIII-2), by project, to each field office before the
         beginning of the fiscal year.  Allotments will cover one fiscal
         year without carryover to the subsequent fiscal year.  The Oak
         Ridge Operations Office allotments will include foreign and
         domestic withdrawals of enriched uranium to be provided by DOE,
         rather than the United States Enrichment Corporation.  The field
         office receiving the allotment should contact the field office that
         is to supply the material to arrange for delivery.

    c.   Allotment Control.  Each field office is responsible for
         monitoring, controlling, and reporting the status of its
         allotments, and for approving all transfers of materials between
         projects.  (See additional requirement in paragraph d, below.)

    d.   Transfer Approvals.  All withdrawals and transfers of very highly
         enriched uranium (94.00% and above U-235) and very low tritium
         content heavy water (<0.00005 microcuries tritium/milliliter)
         require prior approval by the Office of Nuclear Weapons Management.
         Other transfers will be controlled at the project level by the
         field offices.  From time to time, additional material types or
         projects may be added that require approval by the Office of
         Nuclear Weapons Management for transfer of materials between
         projects.  This guidance will be identified in the transmittal of
         the annual allotments.

    e.   Reporting.  Each field office shall provide the Office of Nuclear
         Weapons Management with semiannual allotment status reports that
         compare actual withdrawal and return quantities with quantities
         allotted by project.  The original allotments and all revisions
         issued by the Office of Nuclear Weapons Management for the year
         should be shown.  The first report, covering the first two quarters
         of the fiscal year, is due to the Office of Nuclear Weapons
         Management by 6-1.  Brief explanations should be provided if
         differences of greater than 10 percent are expected for the full
         year between allotted quantities and those currently projected for
         the year.  The full fiscal year report, due to the Office of
         Nuclear Weapons Management by 12-1, should explain differences of
         greater than 10 percent between actual transactions and allotted
         quantities.  Attachment IV-1 shows the format to be used for the
         allotment status reports.

    f.   Allotment Revisions.

         (1)  Withdrawals.  Actual withdrawals of nuclear material that
              exceed allotted quantities must first be approved by the
              Office of Nuclear Weapons Management.  Requests for increases
              are to be sent to the Office of Nuclear Weapons Management
              with a copy to the cognizant Headquarters program.  The
              requests should contain sufficient details to allow a thorough
              evaluation of the proposed change.  If the request is approved
              by the Office of Nuclear Weapons Management and the
              Headquarters program, the Office of Nuclear Weapons Management
              will issue a revised allotment to the requesting field office
              and provide a copy to the field office supplying the material.
              For a decrease to an allotment, notification shall be provided
              to the Office of Nuclear Weapons Management, with a copy to
              the cognizant Headquarters program.  The Office of Nuclear
              Weapons Management will issue a revised allotment and notify
              the applicable field offices of the change.

         (2)  Returns.  The Office of Nuclear Weapons Management and the
              appropriate Headquarters program organization should be
              notified if projected returns for the year are expected to
              vary from allotted quantities.  Explanations of changes should
              accompany the notification.  The Office of Nuclear Weapons
              Management will issue a revised returns allotment and notify
              the field office responsible for receiving and/or processing
              the return.

         (3)  Excepted Quantities.  If total changes in project withdrawals
              or returns allotments for the year are within the following
              quantities, allotment revision approval by the Office of
              Nuclear Weapons Management is not required.
