This regulatory guide describes a method acceptable to the NRC staff for complying with the Commissions regulation

The Advisory Committee on Reactor Safeguards has been consulted concerning this guide and has concurred in the regulatory position.B. DiscussionSubcommittee ANS-3, Reactor Operations, of
4、the American Nuclear Society Standards Committee developed ANSI N18.7-l972, which contained criteria for administrative controls for nuclear power plants during operation. This standard, along with ANSI N45.2. 1971, Quality Assurance Program Requirements for Nuclear Power Plants, was endorsed by Reg
5、ulatory Guide 1.33. The dual endorsement was necessary in order for the guidance contained in the regulatory guide to be consistent with the requirements of Appendix B to 10 CFR Part 50; however, this dual endorsement caused some confusion among users. To clarify this situation, ANSI NI 8.7-1972 was
6、 revised so that a single standard would define the general quality assurance program requirements for the operation phase This revised standard was approved by the American National Standards Committee N IS, Nuclear Design Criteria It was subsequently approved and designated N18.7-1976/ANS-3.2, Adm
7、inistrative Controls and Quality Assurance for the Operational Phase of Nuclear Power Plants,(1) by the American National Standards Institute on February 19, 1976.There had been some uncertainty with regard to the NRC staffs position when a regulatory guide endorses, as an acceptable method, the gui
8、delines as well as the requirements included in a standard. The NRC staff has evaluated the guidelines contained in N18.7-1976/ANS-3.2 with respect to importance to safety. Revision I of this regulatory guide clarified the NRC staffs position on the requirements and guidelines included in ANSI N 18.

10、 guide.Section I, Scope, of ANSI N18.7-1976/ANS-3.2 states that this standard contains criteria for administrative controls and quality assurance for nuclear power plants during the operational phase of plant life and that (his phase is generally considered to commence with initial fuel loading, exc

Other regulatory guides may be issued or this regulatory guide may be revised, if necessary, to amplify the general requirement
12、s contained in this standard.Appendix A to this guide has been further revised as a result of additional comments received on the guide and additional staff review.C.

Typical Procedures for Pressurized Water Reactors and Boiling Water Reactors, to this regulatory guide should be used as guidance to ensure minimum procedural coverage for plant operating activities, including related maintenance activities. Appendix A lists typical safety-r

Many other activities carried out during the operation phase of a nuclear power plant require written procedures not included in Appendix A. Appendix A may also contain proced

The procedures listed in Appendix A may be combined, separated, or deleted to conform to the applicants procedures plan.2.Throughout ANSI N1S.7-1976/ANS-3.2, other documents required to be included as a part of this standard are identified at the point 0f reference.
