SUPPLEMENTARY INFORMATION:

Background

The Nuclear Regulatory Commission amended its rule, 10 CFR 50.59, “Changes, Tests, and Experiments” on October 4, 1999 (64 FR 53582). This amendment clarified the rule requirements, and also provided licensees greater flexibility to make certain changes without NRC approval that involve only minimal increases in likelihood or consequences of events. The implementation date of this amendment was made dependent upon guidance being issued to nuclear reactor licensees on implementing the revised requirements.

Regulatory Guide 1.187 endorses a document prepared by the Nuclear Energy Institute (NEI), NEI 96-07, Revision 1, dated November 2000. Regulatory Guide 1.187 was published for public comment (65 FR 24231) as DG-1095, “Guidance for Implementation of 10 CFR 50.59, Changes, Tests, and Experiments”. The comments submitted by licensees and other commenters were addressed by revisions made by NEI to NEI 96-07, Revision 1, as submitted in November 2000; the NRC staff concurs in these revisions.

Therefore, the effective date of the October 4, 1999, amendment to 10 CFR 50.59 is March 13, 2001.
