INTRODUCTION Paragraph 70.51(c) of 10 CFR Part 70 requires each licensee who is authorized to possess at any one time special nuclear material in a quantity exceeding one effective kilogram to establish, maintain, and follow written material control and accounting procedures which are sufficient to enable the licensee to account for the special nuclear material in his possession under license. While other paragraphs and sections of Part 70 provide specific requirements for nuclear material control systems for fuel cycle plants, such detailed requirements are not included for nuclear power reactors. This guide identifies elements acceptable to this Regulatory Staff for a nuclear material control system for nuclear power reactors. B. DISCUSSION Control and accounting for special nuclear material at a nuclear power reactor is considerably less complex than at other fuel cycle facilities because the material is in the form of identifiable fuel assemblies which can be controlled on an item basis. Nevertheless, control is necessary to ensure that the material is properly accounted for and to provide continuity of control for the total fuel cycle. Subcommittee INMM-1 on Material Control Systems of the Nuclear Standards Committee N15 on Methods of Nuclear Material Control has developed a standard, ANSI N15.8, which provides guidelines on nuclear material control systems for nuclear power plants. C. REGULATORY POSITION The guidelines set forth in the final draft of ANSI N15.8, "Nuclear Material Control Systems for Nuclear Power Plants,"(1) are generally acceptable to the Regulatory staff and provide an adequate basis for systems for the control and accounting for special nuclear material at a nuclear power plant. ---------- (1) Copies may be obtained from the Institute of Nuclear Materials Management, 505 King Avenue, Columbus, Ohio 43201, Attn: Mr. H.
