February 19, 1986 MEMORANDUM FOR: Those on Attached List FROM:
James G. Partlow, Director Division of Inspection Programs Office of Inspection and Enforcement
SUBJECT:
SEISMIC INSTRUMENTATION FAILURES Enclosed for your information -is a July 9,1985 memorandum from K. R. Goller, RES, to J. M. Taylor, IE, that highlights a problem of failures with seismic instrumentation. We evaluated this memorandum and available information on failures of seismic instrumentation. Our review disclosed that since the issuance of IE Circular 81-03, which covered this subject, there has only been one incident involving seismic instrumentation failures. We also noted that power reactors which do not have standard technical specifications (TS) normally do not have TS surveillance requirements for demonstrating the operability of seismic instrumentation, and that all previous failures of seismic instrumentation occurred at these reactors.
Although our review of recent failures of seismic instrumentation did not indicate a broad problem, the operational readiness of seismic instrumentation is an item that we believe warrants periodic inspection coverage. The January 31, 1986 earthquake near Clevelarid,~0hfo affected several nuclear plants, and the importance of having operable, seismic instrumentation was clearly demonstrated. At the Perry Nuclear Power Plant, the seismic instrumentation was activated and provided important data which the licensee and the NRC are using to analyze the event. Therefore, we recommend tha_t maintenance _and_ testing associated.with s_eismic..instrumen_tation be factored into_your_Ioutine_ inspection planni_ng.
If there are any questions on this matter, please contact G. Barber, FTS 492-7473.
