N Palo Verde Unit 1 1ad n unscheduled shutdown on September 12, 1985. During the staff's review, it was determined that the pressurizer auxiliary spray system was not safety grade as understood by the staff when the operating license was issued. The licensee agreed not to restart from a shutdown on September 16, 1985 until the design criteria for the auxiliary spray system was resolved to the satis-faction of the NRC staff. Region V issued a Confirmatory Action Letter on September 20, 1985 stating this comitment.
On September 20; 1985 the licensee met with the staff to provide more inform-ation including an indepth description of the sequence of events, design characteristics of the auxiliary spray system and proposed short term compensatory measures for continued operation. -
On the basis of the commitments made, Region V issued a Confirmatory Action Letter
, dated September 20, 1985, releasing the licensee from its commitment not to return Unit I to power. NRR concurred in this action. The plant went critical Saturday, September 21, 1985 and is currently at 30% power level.

Docket M . .. ??? Alert Site Area Emergency General Energency Not Applicable SU1 JECT: LOSS OF OFFSITE 70WER AT FAID YERDE UNIT 1 On October 3.1985, the licensee declared an Unusust Event at 4:45 pm (MST) as a result of a reactor trip following a losa of normal electric power. At the time of the event, the plant was operating at 501 full power. All systems appeared to have functioned properly in response to the power loss including the two amargency diesel generators which started and ,
anpplied power to the essential busses. Plant cooldown by natural circulation was normal following the loss of the four reactor coolant pumps. Power was restored to the distribution system at 5:03 pm.
Initial attearpts to restart the reactor ecolant pus:ps were unsuccessful at about 5:50 pm. Three reactor coolant pumps were restarted by 8:26 pu by resetting the pump circuit breaker lockout relays. This reestablished forced circulation flow. The Unusual Event was terminated at 8:3$ pin af ter plant conditions had stabilised. The cause of the loss of electric power which inttiated the event is under investigation by the licensee.
The resident inspector was casite at the tir.e of the event. l This information is current as of 7:00 as (HST). October 4.1985.
