Fire suppression water syst s inoperable.

This event is considered to be reportable as defined in the Technical Specificatiana, paragraph 3.12.B.J(2) .

Conditions Prior to Occurrence Routine Shtitdown Operation Power: 0 Mht 0 bMe FlcN: Rocirculation: 5 x 410 p Feed: 0 lbs/hr.

Description of Occurrence On Sunday, January 17, 1982, the fire suppression water systen at Oyster Creek was declared inoperable. 1-2 fire diesel had started for no apparent reason and in the process overheated and was shutdown for maintenance. An operability.

Lest was perfprmed on 1-1 fire diesel to assure its availability. 1-1 fire diesel was subequently declared inoperable in light of the fact that it could not maintain proper engine speed and discharge pressure. A check of the electrically operated redtni?.nt fire suppression water systen revealed it too i was inoperable due to freezi:q of various instrumentation lines.

s Special N port No. 82-1 Page 2 Apparent Cause of Occurrence Extremely low ambient taperature.

The cause of failure of the diesel fire pxps is attributed to extreely it.w ambient tmperatures. he low tenperatures caused frozen cooling water lines, one of which broke. In aMition, the fuel oil cooled below the cloud point which caused partial clogging of the fuel filters. Initiation of the 1-2 fire diesel pump was esased by ci frozen pressure sensing line. W e low ta peratures in the Fire Pmp livuse were the result of the malfunction of two of four installed:-

space heaters. The cause of failure of the electrically operated redundant fire protection systm was loss of pressure control due to frozen sensing lines.

Corrective Action l

me space heaters were repaired and returned to service. The cooling water line to 1-2 Diesel Fire Ptmp was repaired and operability tests on both diesels were .;

performed. Both diesel fire pumps were declared operable at 1310 hours0.0152 days <br />0.364 hours <br />0.00217 weeks <br />4.98455e-4 months <br /> on January 12, 1982. The redundant fire protection syste remains out of service at this tune.
