April 23,1979 PRELIMINARY NOTIFICATION OF EVENT OR UNUSUAL OCCURRENCE--PNO-79-91
- i This preliminary notification constitutes EARLY notice of event of [
POSSIBLE safety or public interest significance. The information presented is as initially received without verification or evaluation '
and is basically all that is known by IE staff on this date.
Facility: Northeast Nuclear Energy Company -
Millstone Point Unit 2 (DN 50-336) /
Waterford, Connecticut *
Subject:
VAPOR BINDING 0F SHUTDOWN COOLING SYSTEM PUMP
" ' ' ' Reportable Occurrence 79-08, Loss of Shutdown Cooling (SDC) and subsequent RCS heatup to Mode 4, describes operation of the SDC system in a degraded mode on March 14, 1979 (30 Day LER). While in the SDC mode the LPSI ;
pump.became air bound resulting in a loss of SDC flow. Subsequent RCS i heatup up to 208 degrees F resulted in entry into Mode 4 (Hot Shutdown). l Compliance with Mode 4 LCO's was verified. To restore LPSI suction the -
licensee took safety measures including establishing containment integrity and having all personnel leave the containment. Suction to the LPSI pump was then shif ted to the RWST and SDC was restored by RCS floodup. Full suction was restored by vacuum priming' the SDC suction lo'o p seal. These -
f planned restoration actions. resulted in the spillover of appro,ximately W2 15,000 gallons of water through an open Steam Generator Manway to the cg containment. There was no release of r Jioactive material to the environs.
This PN is issued for information only due to media interest. The Stat'e '
of Connecticut has been informed. A press release is not planned by the licensee nor NRC. ,
l 8 i NRC, Region 1, (Philadelphia) received notification of this occurrence l by telephone from the Resident Inspector at 2:15 PM on March 14, 1979. >
