RG&E is pleased that the NRC has acknowledged the significant reduction in seismic hazard to the majority of U.S. 'nuclear power plants, including Ginna Station, due to the revised LLNL mean seismic hazard curves. This information was published in Information Notice 94-32, ERI/NRC 94-502, ERI/NRC 94-504, and comments to this effect were made at the public workshop held on October 21, 1994.

We are disappointed, however, by the apparent lack of meaningful response by the NRC to this significant new information. Simply removing the review of soil-structure interaction and reactor vessel internals from the scope of IPEEE, while an important improvement, does not do justice to the comprehensive insights developed in this area by industry and seismic experts.

RG&E agrees with the comments, made by NEI at the October 21, 1994 workshop that, in order to resolve the seismic issue for the majority of plants, emphasis should be placed on a comprehensive seismic walkdown and review by a team of seismic and systems experts. Insight gained from this experience will be factored into utility decision-making inBecause resultant plant changes.

defining the extent, the generic letter does not if any, of establish any legally binding requirements to go beyond the regulations, and because we feel that no important additional insights will be gained from a seismic review above SSE asserts that this walkdown/review should be performed at the levels,'G&E design basis SSE 'for the site (0.2 g for Ginna), thus also resulting in the resolution of USI A-46 in an efficient manner.
