INTRODUCTION
The Atomic Energy Act of 1954, as amended, directs the U.S. Atomic Energy Commission (AEC) to regulate the receipt, manufacture, production, transfer, possession, use, import, and export of special nuclear material in order to protect the public health and safety and to provide for the common defense and security. The principal requirements with respect to special nuclear material licensing are found in Title 10, Code of Federal Regulations, Part 70 (10 CFR Part 70), "Special Nuclear Material." Paragraph (b) of §70.22 of 10 CFR Part 70 specifies that special nuclear material control and accounting information must be provided in a license application to show how compliance with the fundamental nuclear material control requirements of
§70.58 of 10 CFR Part 70 will be accomplished. A special nuclear material control and accounting section must be prepared for the license application, which must be submitted prior to the beginning of construction. In addition to the requirements of 10 CFR Part 70, certain special requirements for material control and accounting would be included in a proposed Part 52 that is currently being prepared specifically for license applications for uranium enrichment plants.
Purpose and Applicability This Standard Format has been prepared to provide uniformity and complete ness in the preparation and review of the special nuclear material control and accounting section of license applications, to minimize lost time attributable to incomplete applications, and to standardize the licensing review process.
Chapter 12 of this document applies to applications for construction and operation of uranium enrichment plants and the additional material control and accounting information required for such plants. In order to facilitate presentation of Chapter 12, it has been written as though the proposed Part 52 currently in preparation were in effect.
This document is applicable to applications for licenses to possess at any one time and location more than one effective kilogram of special nuclear material and to use such material as sealed sources and for activities other than those involved in the operation of a nuclear reactor licensed pursuant to
10 CFR Part 50 and those involved in a waste disposal operation.
The applicant is encouraged to prepare his application in accordance with the Standard Format and to provide information in each section to support the conclusion that he will be able to operate in accordance with the pertinent regulations. The information specified in the Standard Format is the minimum for a license application. Although strict conformance with the Standard Format is not mandatory, presentation of an equivalent level of information is necessary. Additional information may be required for completion of the staff review of a particular application. The applicant should include additional information, as appropriate. In this regard, it is the applicant's responsi bility to be aware of new and revised AEC regulations. The information provided should be up to date with respect to the state of technology for the control of, measurement of, and accounting for special nuclear material.
5.45-12
The applicant is advised to discuss his plans and programs with the Regulatory staff in advance of preparing his license application. This will allow pertinent information to be discussed with respect to the depth of information required for the proposed license.
Upon receipt of an application, the Regulatory staff will perform a preliminary review to determine if the application provides a reasonably complete presentation of the information needed to form a basis for the findings required before issuance of a license. The Standard Format will be used by the staff as a guideline to identify the information needed. If the applica tion does not provide a reasonably complete presentation of the necessary information, further review will be suspended until needed information is provided.
As developments and changes in the nuclear industry occur, the Commission's requirements for information may need modification; revisions to the Standard Format will be made as necessary to accommodate these changes.
Use of the Standard Format The applicant should follow the numbering system of the Standard Format at least down to the level of sections such as Section 2.4.2. Under some circumstances, certain sections may not be applicable to a specific application.
This should be stated clearly, and sufficient information should be provided to support that conclusion.
The applicant may wish to submit information in support of his appli cation which is not required by regulations and is not essential to the description of the applicant's special nuclear material control and accounting program. This could include, for example, historical data submitted in demon stration of certain criteria, discussion of alternatives considered by the applicant, supplementary information regarding assumed models such as the LEMUF Models called for in Chapter 7, or data calculations. This information should be provided as an appendix to the application.
In addition, the information called for in Appendix A, "Site Description,"
to this Standard Format should be submitted as an appendix to the application.
This information is necessary for the assessment of the acceptability of the applicant's material control and accounting plan but should not be incorporated in the special nuclear material license as technical specifications or license conditions.
Upon completion of the application, the applicant should use the table of contents of the Standard Format as a checklist to ensure that each subject has been addressed.
Style and Composition A table of contents should be included in each submittal.
The application should strive for clear presentations of the information provided. Confusing or ambiguous statements and general statements of intent should be avoided. Definitions and abbreviations should be consistent through out the submittal and consistent with generally accepted usage.
5.45-13
The applicant should direct his response to the subject matter of each section. Wherever possible, duplication of information should be avoided.
Thus, information already included in other sections of the application may be covered by specific reference to those sections.
Where numerical values are stated, the number of significant figures should reflect the accuracy or precision to which the number is known. The use of relative values should be indicated clearly.
Drawings, diagrams, and tables should be used where the information may be presented more understandably or more concisely by such means. These should be located with the section in which they are primarily referenced. Due concern should be taken to ensure that all information presented in drawings is legible, symbols are defined, and drawings are not reduced to the extent that they cannot be read by unaided normal eyes.
Physical Specifications of Submittals All material submitted as part of the license application should conform to the following physical dimensions of page size, quality of paper and inks, and numbering of pages:
1. Paper size Text pages: 8-1/2 x 11 inches.
Drawings and graphics: 8-1/2 x 11 inches preferred; however, a larger size is acceptable provided the finished copy, when folded, does not exceed 8-1/2 x 11 inches.
2. Paper stock and ink Suitable quality in substance, paper color, and ink density for handling and for reproduction by microfilming.
3. Page margins No less than one inch on the top, bottom, and binding side of all pages submitted.
4. Printing Composition: text pages should be single spaced.
Type face and style: suitable for microfilming.
Reproduction: may be mechanically or photographically reproduced. All pages of the text may be printed on both sides with the image printed head to head.
5. Binding Pages should be punched for looseleaf ring binding.
5.45-14
6. Page numbering Pages should be numbered by chapter and sequentially within the chapter, e.g., the first page of Chapter 3 would be 3-1, etc. Do not number the entire report sequentially.
7. Format references References in the application to this Standard Format should be by chapter, section number, and subsection number.
Procedures for Updating or Revising Pages The updating or revising of data and text should be on a replacement page basis.
Each changed or revised portion of a page should be highlighted by a vertical line. The line should be on the margin opposite the binding margin opposite each line changed or added. All pages submitted to update, revise, or add pages to the report should show the date of change. The transmittal letter should include an index page that lists the pages to be inserted and the pages to be removed. Where major changes or additions are made, pages for a revised Table of Contents should be provided.
Number of Copies The licensee should submit the number of copies of each required sub mittal specified in §70.21 of 10 CFR Part 70 or which would be required in a new 10 CFR Part 52.
Public Disclosure The AEC has determined that public disclosure of the details of special nuclear material control and accounting programs is not in the public interest, and withholds such details pursuant to paragraph 2.790(d) of 10 CFR Part 2.
Thus the special nuclear material control and accounting section of each license application should be submitted as a separate enclosure. Other propri etary and classified information should be identified clearly and submitted in separate enclosures. Each submission of proprietary information should be accompanied with the applicant's detailed reason and justification for request ing exemption from public disclosure as required in paragraph 2.790(b) of 10 CFR Part 2.
Compatibility The applicant should ensure that the special nuclear material control and accounting plan is compatible with the other sections of his application.

STANDARD FORMAT AND CONTENT FOR THE SPECIAL NUCLEAR MATERIAL CONTROL
AND ACCOUNTING SECTION OF A SPECIAL NUCLEAR MATERIAL LICENSE APPLICATION
(Including that for a Uranium Enrichment Facility)
CHAPTER 1 DESIGN OF STRUCTURES, COMPONENTS,
EQUIPMENT, AND SYSTEMS
This chapter of the application should identify, describe, and discuss the principal design characteristics of those structures, components, equipment, and systems important to special nuclear material control and accountin
g. A
special nuclear material control and accounting section must be prepared for the license application. Pursuant to paragraph (f) of §70.21 of 10 CFR Part 70, this section is required to be submitted prior to the beginning of construc tion and it also would be required pursuant to provisions of a new 10 CFR Part 52. In general, the application submitted prior to construction should describe the preliminary design of the plant in sufficient detail to allow a definitive evaluation by the Regulatory staff as to whether the plant can be constructed with adequate provisions for the control and accounting of special nuclear material.
The design information provided should reflect the most advanced state of design at the time of submission. If certain information identified in the Standard Format is not yet available at the time of submission because the design has not progressed sufficiently at the time of writing, the application should include the bases and criteria being used to develop the required information, the concepts and alternatives under consideration, and the schedule for completion of the design and submission of the missing information.
The application should be modified prior to operation to describe in detail the final design of the plant, as well as operating procedures signifi cant to the control and accounting of special nuclear material. Modifications of the design bases, criteria, or features included in the application submitted prior to construction, as well as any new or modified design bases, criteria, or features, should be identified in the application modifications submitted prior to operation. The safeguards significance of each such change should be addressed. The relation of the design bases to the design criteria should be described.
1.1 Design Bases, Criteria, and Features In this section, discuss briefly the design bases, criteria, and features for the plant structures, systems, equipment, and components important to special nuclear material control and accounting. Identify and discuss, where appropriate, the relationships of special nuclear material control and accounting design characteristics with other design characteristics such as process control and health and safety. The design base should provide information which identifies the function to be performed by a structure, system, component, or pieces of equipment. Design criteria should establish design, fabrication, construction, testing, and performance requirements associated with the respec tive design bases. For each criterion, a summary should be provided to show how the principal design features meet the criterion. Any exceptions to the
5.45-16
criteria should be identified, and the justification for each exception should be discussed. In the discussion of each criterion, reference the sections of this report where more detailed information is presented. The discussion in this section should include at least the following:
1.1.1 Material Control Areas Identify and explain the design characteristics that were used to establish the plant and internal control areas identified in Section 4.1.
1.1.1.1 Design Criteria for Subdivision of a Site to Improve Control.
Present and discuss the design criteria related to special nuclear material control and accounting that were used to establish the plant and internal control areas, including such criteria as assurance of identifiable physical areas, capability to control special nuclear material by area, and capability to assign a measured value to special nuclear material entering or leaving an area.
1.1.1.2 Design Features. Identify and describe the plant and process design features that provide for establishment of internal control areas identified in compliance with the design criteria discussed in Section 1.1.1.1, including, for example, site and plant layout, building structures, and equipment arrangement.
1.1.2 Automated Special Nuclear Material Control and Accounting Capability Identify those design characteristics that provide for the capability, if any, for automated special nuclear material control and accounting, including process design and layout to permit automated process control, automated measurement systems, and automated access controls.
1.1.2.1 Design Criteria. Present and discuss the design criteria that were used to establish the capability for automated special nuclear material control and accounting, if any, including such criteria as timely calculation of material balances for plants and control areas, maintenance of current knowledge of the identity, location, and quantity of special nuclear material in the areas, and limitation of personnel access to the material and material accounting data.
1.1.2.2 Design Features. Identify and describe the plant and process design features that provide for automated special nuclear material control, if any, in compliance with the criteria discussed in Section 1.1.2.1, including, for example, process layout, mechanization, and automation; storage and handling mechanization and automation; and in-line measurement systems.
1.1.3 Measurement Capability Identify those design characteristics that provide: (1) the capability to measure the special nuclear material content of all receipts, shipments, and inventories and (2) systems to assure continued validity of previous measurements. Such characteristics could include capabilities for mixing, sampling, weighing, volume determination, and chemical and nondestructive analyses (see also Chapter 5, Section 5.2.2.3).
5.45-17
1.1.3.1 Design Bases. Design bases for a measurement system should show the function of the system to provide for measurement of special nuclear to make to material and the limiting contribution that the system is permitted the total material balance uncertainty. The design base for any specific measurement, i.e., the total measurement at a specific point or the individual components of such a measurement, e.g., weighing, sampling, or analyzing, contribution should show the function the measurement performs and the limiting system which that measurement is permitted to make to the total measurement uncertainty.
1.1.3.2 Design Criteria. Design criteria for a measurement system and the limits of or any of its parts should show how measurements will be made to meet the precision and accuracy that will permit the system and its parts design bases.
1.1.3.3 Design Features. Design features should describe those character the system to istics of the measurement system and its parts that will permit meet the design criteria.
