ENCLOSURE RESPONSE TO BULLETIN 88-03 SALEM GENERATING STATION UNIT NO. 1 DOCKET NO. 50-272 The purpose of this bulletin was to request licensees to perform inspections to ensure that all GE latching-type HFA relays installed in safety-related applications have adequate latch engagement and that those relays which fail to meet acceptance criteria be repaired or replaced.

The bulletin requested a letter of confirmation that the inspection had been completed and a summary of the number of relays inspected and any corrective actions taken. This information is presented below as it relates to_ Salem Unit 1.

RESPONSE

The NRC Bulletin 88-03 GE HFA latching-type relay inspection for Salem Unit 1 was performed in May 1989 during the Eighth _

Refueling Outage. Documentation reviews and field examination revealed twent:y-one (21) HFA latching-type relays, seven in each of the three emergency diesel generator control cabinets. The relays all have the Model No. 12HFA54H187H.

All of these relays were checked in accordance with a special test procedure (T-246) written to address those criteria noted in the Actions Requested portion of the NRC Bulletin 88-03. The results of the examinations of all the relays were found to be satisfactory. The Procedure T-246 data sheets are available onsite for inspection, if requested.

Until alternatively designed relays are made available which remedy the problem noted in NRC Bulletin 88-03, spare GE HFA latching-type relays of the model noted above have been ordered for replacement-in-kind applications, if replacement should be necessary in the future. These spare relays will be inspected in accordance with the criteria of NRC Bulletin 88-03 upon receipt.
