IlAR 2 0 WOS Docket No. 50-440 Mr. Murray R. Edelman Vice President - Nuclear Group The Clevland Electric Illuminating Company P.O. Box 5000 Clevland, Ohio 44101
Dear Mr. Edelman:
SUBJECT:
ACRS REPORT ON THE PERRY NUCLEAR POWER PLANT, UNIT 1 Enclosed for your comments is the ACRS March 17, 1986 report to the Chairman of the Nuclear Regulatory Commission regarding the earthquake event which occurred near the Perry Nuclear Power Plant site on January 31, 1986. We particularly would like input on your plans and schedule with respect to the recommandation made in that report regarding the use of sensitive seismological instruments over the next few years for the assessment of any connection between the chemical waste injection wells and the January 31, 1986 earthquake event.
It is requested that you advise the Perry Project Manager (John J. Stefano),
within one week after receipt of this letter, of your comments on the enclosed report, and of your plans and schedule for the seismological monitoring of the injection wells.
Sincerely, Orfdantmen.e3,-

Dear Dr. Palladino:
SUBJECT:
ACRS REPORT ON THE PERRY NUCLEAR POWER PLANT, UNIT 1 During its 311th meeting, March 13-15, 1986, the Advisory Comittee on Reactor Safeguards discussed the Ohio earthquake which occurred on January 31, 1986 and reviewed its implications with respect to the Perry Nuclear Power Plant, Unit 1.
A meeting of the Subcommittee on Extreme External Phenomena was held on March 12, 1986 to consider this matter.
The Reactor Operations Subcommittee discussed this matter during a meeting on February 12, 1986 and the full Comittee was briefed during the 310th ACR5 meeting, February 13-15, 1986. During our review, we had the benefit of discussions with representatives of The Cleveland Elec-tric Illuminating (Company (Applicant), the NRC Staff, and the Geological Survey USGS) Staff.
We also had the benefit of the docu-We com-ments referenced and coments from several ACR5 consultants.

13, 1982.
This earthquake occurred near tercy Ohio, and was characterized by relatively low energy, low velocities, small displacements, a short duration, and a response spectrum rich in high frequencies.
Except at the relatively less significant high frequencies,ithe excitation of the plant structures and equipment was much less than that considered in the seismic design basis.
No significant damage was observed at the Perry plant in the inspections which were performed by the Applicant and the NRC Staff." The Cieveland Electric Illuminating Company, by using analysis and comparisons with prior qualification testing, has found that all the structures and l
equiment analyzed thus far have substantial margins of safety relative l
to tie loads and stresses induced by the earthquate. The NRC Staff and our consultants concur in that conclusion.
The NRC Staff has several confirmatory actions that it will require of These con-the Applicant prior to operation above 5 percent power.
firmatory actions include the analyses of a large sample of equipment.
We support the NRC Staff's proposed confirmatory actions.
There currently exists some possibility that the January 31, 1986 earthquake is related to deep well injection activities that took place between the Perry plant site and the town of Leroy or to solution mining 2-d/-W -.
