GUIDE 5.29 NUCLEAR MATERIAL CONTROL SYSTEMS FOR NUCLEAR POWER PLANTS  


==A. INTRODUCTION==
==A. INTRODUCTION==
Purpose  This guide describes a method that the staff of the U.S. Nuclear Regulatory Commission (NRC) considers acceptable to implement special nuclear material control and accounting system requirements for nuclear power plants.  This guide applies to all nuclear power plants.
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 that 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 con trol systems for fuel cycle plants, such detailed require ments are not included for nuclear power reactors.
Applicable Rules and Regulations Title 10, of the Code of Federal Regulations, Part 74, "Material Control and Accounting of Special Nuclear Material" (10 CFR Part 74) (Ref. 1), Subpart B, "General Reporting and Recordkeeping Requirements," establishes the material control and accounting performance requirements for special nuclear material at nuclear power plants.  The regulations at 10 CFR 74.11, "Reports of loss or theft or attempted theft or unauthorized production of special nuclear material," require, in part, that nuclear power reactor licensees notify the NRC of any such events within one hour of discovery.  The regulations at 10 CFR 74.13, "Material status reports," require nuclear power reactor licensees to submit material status reports for certain quantities of special nuclear material.  The regulations at 10 CFR 74.15, "Nuclear material transaction reports," require nuclear power reactor licensees to complete transaction reports when transferring, receiving, or making adjustments to specified quantities of special nuclear material.  The regulations at 10 CFR 74.19, "Recordkeeping," require, in part, that nuclear power reactor licensees keep records that show the receipt, i nventory (including locati on and unique identity), acquisition, transfer, and disposal of all special nuclear material in their possession. Additionally, 10 CFR 74.19 requires, in part, that licensees establish, maintain, and follow written material control and accounting procedures, and that they conduct physical inventories of special nuclear material at intervals not to exceed once every 12 months.
 
Purpose of Regulatory Guides


The NRC issues regulatory guides to describe met hods that the staff considers acceptable for use in implementing specific parts of the agency's regulat ions, to explain techniques that the staff uses in evaluating specific problems or postulated accidents, and to provide guidance to applicants.  Regulatory Rev. 2 of RG 5.29, Page 2 guides are not substitutes for regulations and compliance with them is not required. Methods and solutions that differ from those set forth in regulator y guides will be deemed acceptable if they provide a basis for the findings required for the issuance or continuance of a permit or license by the Commission.
This guide identifies elements acceptable to the NRC staff for a nuclear material control system for nuclear power reactors.
 
This regulatory guide provides ANSI N15.8-2009 as an acceptable approach to the NRC staff for complying with the NRC's regulations regarding material control and accounting requirements in Subpart B of 10 CFR Part 74 at nuclear power plants.
 
Paperwork Reduction Act This regulatory guide contains information collection requirements covered by 10 CFR Part 74 that the Office of Management and Budget (OMB) approved under OMB control number 3150-0123.  The NRC may neither conduct nor sponsor, and a person is not required to respond to, an information collection request or requirement unless the requesting document displays a currently valid OMB control number.


==B. DISCUSSION==
==B. DISCUSSION==
Reason for Revision
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 that 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-l on Material Control Systems of the Nuclear Standards Committee
"*Lines indicate substanlivc changes from previous issue.NI5 on Methods of Nuclear Material Control has developed a standard.


Revision 1 to Regulatory Guide 5.29, "Nuclear Material Control Systems for Nuclear Power Plants," issued June 1975, (Ref. 2) found American National Standards Institute (ANSI) N15.8-1974, "Methods of Nuclear Material Control-Material Control Systems-Special Nuclear Material Control and Accounting Systems for Nuclear Power Plants" as an acceptable method for implementing NRC's requirements for material control and accounting of special nuclear material at nuclear power plants.  However, this standard primarily addressed control and accounting of fuel assemblies and did not address fuel rods that are separated from the parent assembly.  Additionally, ANSI N15.8-1974 did not provide specific guidance on control and accounting of pieces resulting from fuel damage.  The NRC, therefore, withdrew Regulatory Guide 5.29 in January 1998 (63 FR 2426).  In the absence of endorsed guidance, licensees relied on site-specific procedures and processes to implement material control and accounting requirements, and licensee programs and procedures were reviewed by the NRC on a case-by-case basis.
ANSI N15.8, which provides guidelines on nuclear material control systems for nuclear power plants.  C. REGULATORY
POSITION The guidelines set forth in ANSI N]5.8-1974,l "Nuclear Material Control Systems for Nuclear Power Plants,"'
are generally acceptable to the NRC staff andi provide an adequate basis for systems for the control and accounting for special nuclear material at a nuclear power plant.


Subsequently, ANSI revised its standards for special nuclear material control and accounting and published ANSI N15.8-2009, "Methods of Nuclear Material Control-Material Control Systems-Special Nuclear Material Control and Accounting Systems for Nuclear Power Plants" (Ref. 3).  ANSI N15.8-2009 provides guidance on the control and accounting of 1) fuel rods that are separated from their parent assemblies; and 2) pieces of irradiated material that are separated as a result of fuel damage.
==D. IMPLEMENTATION==
The purpose of this section is to provide information to licensees regarding the NRC staffs plans for utilizing this regulatory guide.  This guide reflects current regulatory practice.


Revision 2 is also consistent with the recommendations in U.S. Government Accountability Office 05-339, "NRC Needs To Do More To Ensure That Power Plants Are Effectively Controlling Spent Nuclear Fuel" (Ref 4).
Therefore, except in those cases in which the licensee proposes an altefnative method for complying with specified portions of the Commission's regulations, the method described herein will be used in the evaluation of a licensee's performance in connection with nuclear material control systems for nuclear power plants after this guide is issued.  Copies may be obtained from the American National Standards Institute.
Background Control and accounting for special nuclear material at a nuclear power plant are considerably less complex than at other facilities, such as fuel cycle facilities, because the material is usually maintained in the form of readily identifiable fuel assemblies that can be managed on a per-item basis.  However, problems in control and accounting can arise when fuel rods become separated from the parent assembly.  Maintaining proper control is necessary to ensure that licensed material is properly accounted for in a manner that provides continuity of control throughout the total fuel cycle.
 
Rev. 2 of RG 5.29, Page 3  The material control and accounting process is designed to use control and monitoring measures to prevent or detect loss when it occurs or soon thereafter.  Additionally, statistical and accounting measures are used to maintain knowledge of the quantities of special nuclear material present in each area of a facility.  Physical inventories and material balances are used to veri fy the presence of licensed material or to detect the loss of such material after it occurs, in particular, through theft by an insider.
 
Harmonization with International Standards The International Atomic Energy Agency (IAEA) has established a series of safety guides and standards constituting a high level of safety for protecting people and the environment.  IAEA safety guides present international good practices and increasingly reflects best practices to help users striving to achieve high levels of safety.  Pertinent to this regulatory guide, "IAEA Nuclear Security Series No. 13, Nuclear Security Recommendations on Physical Protection of Nuclear Material and Nuclear Facilities," issued January 2011, (Ref. 5) et. al. , address considerations necessary for a nuclear material security program.  While the NRC has an interest in facilitating the harmonization of standards used domestically and internationally and because security requirements typically follow requirements identified in the CFR, the NRC does not specifically accept the IAEA document for use, and is only acknowledging that it may be valuable as a reference for general programmatic information.  The NRC could consider the use of the international standard in a licensing action follo wing adequate justification and technical review.
 
Documents Discussed in the Staff Regulatory Guidance This regulatory guide endorses the use of a voluntary consensus standard developed by an external organization.  This standard may contain references to other codes or standards ("secondary references").  If a secondary reference has itself been incorporated by reference into NRC regulations as a requirement, then licensees and applicants must comply with that standard as set forth in the regulation.  If the secondary reference has been accepted for use in a regulatory guide as an acceptable approach for meeting an NRC requirement, then the standard constitutes a method acceptable to the NRC staff for meeting that regulatory requirement as described in the specific regulatory guide.  If the secondary reference has neither been incorporated by reference into NRC regulations nor endorsed in a regulatory guide, then the secondary reference is neither a legally-binding requirement nor a "generic" NRC approval as an acceptable approach for meeting an NRC requirement.  However, licensees and applicants may consider and use the information in the secondary reference, if appropriately justified and consistent with current regulatory practice, consistent with applicable NRC requirements such as 10 CFR 50.59.
 
C.  STAFF REGULATORY GUIDANCE
  The staff considers conformance with the provisions of ANSI N15.8-2009 an acceptable approach to meet the material control and accounting requirements in Subpart B of 10 CFR Part 74 at nuclear power plants.
