POWER AUTHORITY OF THE STATE OF NEW YORK JAMES A. FITZPATRICK NUCLEAR POWER PLANT DOCKET NO. 50-333 ATTACHMENT TO LER 79-064/03L-0 Page 1 of 1 During normal startup operations, while ccnducting Operations Surveillance Test F-ST-4E titled "HPCI Sub-sys tem Logic Funct ional Tes t," which was being conducted to satisfy the requirements of Technical Speci fications Appendix A, Table 3.2-2, the motor on the systems Condensate Storaga Tank suction valve failed. At this time reactor pressure was between 100-1f0 psig.

After extensive review by the Plant Operating Revier Commi ttee (PORC), i t was determined that the failed motor should be replaced by an identical motor f rom the system's torus suction valve (23-MOV-57) . This latter suction valve provides an alternate and secondary source of water to the HPCI system. It was further directed by the PORC that 23-MOV-57 be p! aced in the open position in orcer to allow the HPCI system to take suction from the torus if required.

In addition, the other torus suction valve (23-MOV-58) was to be veri fied closed to satisfy primary containment isolation requirements contained in Technical Specifications Aopendix A, Paragraph 3.7.1. Subsequently, the motor was removed from 23-M0V-57 as directed by the PORC, however, the valve was not placed in the open position. This condition was discovered approximately five hours af ter reactor pressure was increased above 150 psig, thus, the torus wa, not automat ically available to the HPCI system for a five-hour period during which systuu operability was required Sy Technical Specifications. Since the condensate storage tank suction valve to the HPCI system we in its normal open position, and both condensate storage tanks were nearly full, some 30C,000 gallons of water was available to the HPCI system in the event its operation was requi red. In view of this large reserve of water in the condensate storage tanks, the HPCI system would have operated normally. Minimal safety sign

• f i cance occurred from this event since the system would have operated automatically for a period of more than one hour before manual opening of the torus suction valve would have been requi red.

As soon as the condition was discovered, 23-MOV-57 was pla'ed in the open position and the position was logged oa a daily basis until 1.ie motor was re-placed and proper operation was demonstrated. The motor was replaced on S eptembe r 14, 1979 and found acceptable by completion of Operations Surveillance Test F-ST-4D ti tled "HPCI MOV Operabili ty Test."

Investigation into the cause of not opening the valve at the proper time revealed the plant's management did not adequately communicate to the plant's Operations and Maintenance personnel the importance of placing the valve in the open posi tion prior to the commencement of the repai r. This point was brought to the attention of the Shift Supervisor and the significance of this event has been discussed with the Operations Department.
