ANSI NI8.7-1976/ANS-3.2 requires the preparation of many procedures to carry out an effec-tive quality assurance program. Appendix A,"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, in-cluding related maintenance activities.

This standard, along with ANSI ministrative controls and quality assurance for nu N45.2-1971, "Quality Assurance Program Require clear power plants during the operational phase of ments for Nuclear Power Plants," was endorsed by plant life and that this phase is generally considered Regulatory Guide 1.33. The dual endorsement was to commence with initial fuel loading, except for cer necessary in order for the guidance contained in the tain preoperational activities. In this regard, a sepa regulatory guide to be consistent with the require rate regulatory guide addressing the quality assurance ments of Appendix B to 10 CFR Part 50; however, program for the preoperational phase will be issued.
