Dear Mr. Davidson:
s,,
Subject:
Request for Additional Infomation - Geology
' Perry Nuclear Power Plart, Units 1 & 2 In the performance of the Perry licensing review, the staff has identified concerns in regard to geology._ The information that we require is identified in the enclosure.
A draft of this request was provided in July 1981 and discussed in detail in -
i a telecon on August 26, 1981. Based on the previoos communications, we feel that responses to these requests should be fairly well formulated. Therefore, we request that finished responses be provided 'as they become available and that all infomation be provided no later than Decenber 1,1981. If you require any clarification of this request, pleasa contact M. D. Houston, Project Manager, at (301) 492-8430.
