January 6, 1981 Occurrence Date:

12/7/80 Facility:

Salem Generating Station, Unit 1 Public Service Electric and Gas Company Hancocks Bridge, New Jersey 08038 IDENTIFICATION OF OCCURRENCE:

Containment Spray System Failed to Meet Surveillance Requirements CONDITIONS PRIOR TO OCCURRENCE:

Operational Mode 5 Cold Shutdown DESCRIPTION OF OCCURRENCE:

During performance of SP(O) 4.6.2.2(d) Containment Spray-Spray Additive, a spray additive tank eductor flow rate of 35 + 3.5 gpm IAW surveillance requirement 4.6.2.lc.2 was not achieved.

An indicated flow rate of 57 gpm was obtained using the No. 12 Con-tainment Spray Pump.

A sodium hydroxide solution flow rate of 7.3 + 0.7 gpm with the Spray Additive Tank pressure at 2.5 + 0.5 psig IAW surveillance requirement 4.6.2.2d was not achieved either.

A flow rate of 11.9 gpm with a tank pressure of 2.8 psig was obtained.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

The cause of this occurrence is the differences that exist between startup procedure 18.1 and the surveillance procedure SP (O) 4.6.2.2(d).

During startup, flow was directed to the 8" test connection discharging via temporary piping through the equipment hatch to the yard drains.

Both Containment Spray Pumps were used concurrently to pump demin-eralized water.

During the surveillance test, flow was returned to the RWST via the mini-flow line.

The Containment Spray Pumps were used individually.

A 30% sodium hydroxide solution was in the Spray Additive Tank and, therefore, borated water was recirculated.

The size of the orifice of the flowmeter in the line from the Spray Additive Tank to the eductors was reduced in the interim between the two tests to accommodate a more sensitive flowmeter.

ANALYSIS OF OCCURRENCE:

The flow rates obtained during this test were greater than those required by the Technical Specifications.

PSE&G safety evaluation SGS/M-074, revision 1, concludes that with the current surveillance procedure, the flow rates are acceptable.

If the original startup procedure had been used, SGS/M-074, Revision 1, concludes that the Technical Specification requirements would have been met.

CORRECTIVE ACTION

The PSE&G safety evaluation, SGS/M-SE-074, revision 1, determined that the Spray Additive Tank eductor flow rate of 57 gpm water flow is equivalent to 35 gpm sodium hydroxide flow.

The flow rate required by Technical Specification 4.6.2.2d has been changed to 12.0 + 3.0 gpm.
