SUBJECT:

BOARD NOTIFICATION 86-03 NRC STAFF PRELIMINARY INVESTIGATION OF AN EARTHQUA';E WHICH OCCURRED IN THE VICINITY OF THE PERRY NUCLEAR POWER PLANT SITE This Notification is being provided to the Comission in accordance with the

current Board Notification policy. Parties to the Perry OL-Proceeding are being notified by copy of this memorandum.'

At 11:48 a.m. (EST) on Friday, January 31, 1986, an earthquake was experienced at the Perry plant having a magnitude of 5.0, as reported by the U.S. Geological

• Survey. The epicenter of the earthquake appears to be located at a point

approximately 10 miles south of the plant site.

i. The earthquake activated alarms in the Perry, Unit I control room which prompted the licensee to declare a site ~ area emergency, although not required to do so l

L since the plant has not yet been licensed to operate. A NRC investigation team visited the plant site on February 1-2, 1986, to inspect the plant for any damage b

and to obtain data recorded by earthquake sensing equipment. installed in the plant (the first such data obtained from a nuclear plant outside of California).

I Preliminary findings determined from the investigation team's site visit are as y follows:

?-

!i 1. Plant walkdowns revealed little or no damage to the plant. A pipe flange

! on the hot water heater in the radwaste treatment building developed a small water leak and some hairline cracks were observed in concrete walls below grade in the auxiliary, intermediate and radwaste treatment buildings.

Several of the cracks are known to.have existed' prior to the earthquake.

(

p 2. Two systems electrically tripped as designed when vibration monitors were activated by the earthquake. The auxiliary boiler used for plant space

heating tripped due to a change in water level. A significant number of

~

safety and non-safety systems were in operation and being tested in pre-paration for plant licensing at the time of the event. These systems did l< not appear to be affected by the earthquake.

3. The first load of nuclear fuel for Perry Unit 1, currently stored at the plant, was not' damaged and there were no radiological consequences on-site or off-site.

4. Evaluation of data recorded by the seismic motion sensors in various parts of the plant have not been completed. However, based on a preliminary assessment of the data, it appears that the seismic motion data mainly fall within the OBE/SSE design spectrum, except possibly in the relatively high frequency range, i.e. , greater than 15 Hz. An analysis by the licensee is underway to determine whether or not (and if so to what extent and at what frequency) the design spectrum was exceeded. A meeting with the licensee is scheduled for February 11, 1986, at the plant site, during which time the

licensee will advise NRC of his$reliminary findings on this event, and his plan of action.

The NRC staff's evaluation of this earthquake event will be factored into the

~

decision to issue ar. operating license for Perry Unit 1.

We will keep the Commission and the parties in the Perry 0L-Proceeding advised of significant developments on this issue as they occur.
