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.
