'MOWMM. C 0F) pREL1MINARY HOTIF1 CATION OF EVENT OR UNUSUAL OCCURREffCE--PNO-Tal- 82-02 January 14, 1982 This preliminary notification constitutes EARLY notice of events of POSS!BLE safety or public interest signi ficance. The information is as initially received without verifi-on or evaluation and is basically all that is known by NRC staff on this date, ility: Metropolitan Edison Company Licensee Emergency Classification:
Three Mile Island, Unit 2 X Not Applicable Docket No. 50-320
Subject:
LEAK FROM B0 RATED WATER STORAGE TANK (BWST)
At 4 :00 PM on January 13, 1982, an NRC Resident Radiaticn Specialist noted, through routine review of licensee's logs, that valve DHIV 28 (instrument pipe and valve to
)
BWST sample point) of the BWST had leaked. The leak rate was estimated to have been approximately 1 liter / minute; as much as 180 liters could have spilled to the ground .
at one side of the tank. Initial sample of the liquid indicated the following activity:
137C s - 3.7 E-4 uC1/ml 134C s - 1.1 E-4 uCi/ml 60C o - 1.3 E-5 uCi/ml >
The leak is believed to have been caused by the recent extreme cold weather which froze a small pipe (3/8 inch) and subsequently cracked a pipe fitting. The leak began after a backup heat tracing line was put in service at about 10:00 AM'on 1/13/82.
Upon detection, the licensee immediately isolated the leak.
, ' licensee contained the area and plans to rentve the contaminated soil from the spill
. . Future results of the licensee's ground water monitoring program will be audited ,
y the TMIPO, as historically Test Boring 2 (East of BWST) has shown periodic positive -
indications believed attributed to past leakage from the BWST.
Media interest may occur because of public sensitivity to TMI related events and the (9 licensee issued a press release. The NRC does not plan to issue a press release at \
this time. The Commonwealth of Pennsylvania was informed.
This preliminary notification is issued for information only u:id the NRC plans to continue monitoring events as they occur.
p\ l l
The NRC TMI Program Office received notification of this occurrence by inspector review
' of licensee's logs at 3:45 PM on January 13, 1982, and this information was current as of 5 :30 PM, Januar 14, 1982.
