SUMMARY

RE?0RT OF THE EARTHQUAKE MEETING AT THE PERRY PLANT SITE ON FEBRUARY 11, 1986 -

The meeting was held to discuss CEI's preliminary findings from its

' assessment of the impact of the January 31, 1986 earthquake on the as-built Perry plant design, and to discuss the operational readines.5 of Perry Unit 1 i

for licensing. This report briefly summarizes discussions held in the morning of February 11, 1986, which were limited solely to the earthquake event and its aftermath. The NRC regional staff will report separately on discussions held in the afternoon of February 11, 1986, relative to the Perry Unit I readiness for licensing.

Enclosure (1) lists the NRC, USGS and principal CEI representatives who par-ticipated in the meeting. Other CEI personnel and members from the press, U.S.

Congressional staff, the intervenors and other interested parties were also in attendance, but are not listed in Enclosure (1). Enclosure (2) contains the meeting notice (issued by the NRC Region III Office) and the slide presentation handout prepared by CEI and distributed to the meeting attendees.

In summary, CEI presented its independent investigative findings of plant status prior to, during, and after the earthquake event, including a listing of the safety and non-safety systems that were undergoing operational readiness tests when the event occurred; characterized the earthquake event and its geographical location relative to the plant site; described the geologic structure upon which the plant was built; and discussed the analytical results obtained from the seismic data recorded by instruments positioned at various

' locations within the Perry plant buildings. On the basis of CEI's analysis _i of the data recorded, CEI and its consultants have concluded that: (1)the tectonic province considered in defining soil-structure interactions for the l Perry site-specific safe shutdown earthquake (SSE) intensity remains valid a as described in the FSAR and as evaluated by the NRC staff in the Perry SER; and (2) that the exceedance of SSE limits recorded at the higher frequencies (greater than 16 Hz) was of such a short duration (less than 1 second), low velocity and small displacement as to not have imparted any significant energy to the plant structure and the components, systems, and equipment installed therein; although a spore detailed assessment of the impact, if any, on the qualification of safety-related equipment in the plant has not yet been fully G603060118 860225 PDR A

I completed. In view of these conclusions, CEI maintained that the SSE design basis for the Perry plant remains valid. These conclusions appear to be borne out by the fact that little or no damage had been observed during an intense ,

walkdown of the plant conducted by the CEI staff. l The NRC staff advised CEI that it still needed to conduct its own independent i evaluation of the earthquake and that this effort would consider CEI's findings  ;

(a detailed report was filed by CEI with the Commission on February 12,1986). '

The NRC staff also informed CEI that the issue would be discussed with the ACRS, and that meetings with the ACRS Subcommittee and the ACRS Full Consnittee were scheduled for February 12 and 13,1986, respectively. (NRC and CEI briefed the ACRS on those dates). Lastly, the NRC staff advised CEI that its independent

' evaluation would not be completed before March 1,1986, and that completion of its evaluation by that date assumed receipt of all outstanding data promised by CEI before February 17, 1986.

The morning session of the February 11, 1986 meeting was completed at 11:30 am after which time the NRC staff answered questions posed by the press and public representatives in attendance. The NRC staff also met with its respective CEI technical counterparts to go over in more detail the information presented by CEI during the formal meeting.
