Jpouse of Representatibeg IBastington, D.C. 20515 February 4,1986 Htnorable Nunzio J. Palladino Chainnan Nuclear Regulatory Comission 1717 H Stmet. N.W.

Washington, D.C. 20555

Dear Mr. Chainnan:

On Monday morning, February 3, we were briefed by several members of the NRC staff concerning the impact of last Friday's earthquake on the Perry Nuclear Power Plant in Perry, Ohio. Although we malize information currently avail-able is still preliminary, we appreciate the Comissicn taking the time to keep us up to date. Mr. Carl Papereillo Director of the Division of Reactor Safety at NRC's Region III, and leader of the NRC investigation team sent to Perry after the incident, was particularly informative.

During the course of the briefing, we learned, among other things, that the data recorded by the seismic indicators at the Perry facility during the event

~

will be evaluated by the vendor companies who provided those devices to the licensee.

Obviously, the analysis of the data, uncertainties implicit in any such analysis, and the relationship of the results of the analysis vis-a-vis compliance with the Comission's seismic criteria and regulations is of cri-tical importance. Of additional concern is the fact that a seismic event of this magnitude has apparently never before occurmd at a nuclear power plant in the United States, giving the actions we take now a special significance for the future.

Therefore, we are requesting that the Comission seek a review of the data and its implications by the Advisory Comittee.on Reactor Safeguards (ACRS) and its seismic consultants, including those seismologists and earthquake engi-neers who have assisted the ACRS in its evaluation of 'Diablo Canyon, San Onofre, and other plants where earthquake considerations were important.

Mr. Paperiello indicated during yesterday's briefing that the vendor compan-ies' analysis should be complete by the end of this week. Accordingly, we would appreciate hearing from you on Monday, February 10 regarding the initial results of that analysis, as well as a target date for completion of the independent review.

k you in agce for your continued cooperation.
