Proposed Generic Communication; Degradation of Steam Generator Internals

On December 31, 1996 (61 FR 69116), the NRC published for public comment a proposed generic letter concerning the importance of performing comprehensive examinations of steam generator internals to ensure steam generator tube structural integrity is maintained in accordance with the requirements of Appendix B to 10 CFR part 50. The generic letter will enable the NRC to verify whether or not the condition of addressees' steam generator internals comply and conform with the current licensing basis for their respective facilities. The comment period for this proposed generic letter was originally scheduled to expire on January 30, 1997. In a letter dated January 27, 1997, the Nuclear Energy Institute requested a 45-day extension of the comment period to permit sufficient time to reach consensus on a coordinated industry response. In response to this request, the NRC has decided to extend the comment period.
