Subject:
ONSITE GROUND WATER MONITORING PROGRAM UPDATE 3
The licensee verbally reported that water samples taken from wel
?
d' February 11, 1981, contained increased concentrations of Cesium-137 (Cs-137)
(371 pci/1) and Cs-134 (134 pci/1) and Cobalt-60 (Co-60) (14.3 pci/1).
Well No. 2 is an onsite well, which is located a few yards east of the Borated Water Storage Tank (BWST) (see attached diagram). These results represent an increase (approximately, an order of magnitude) in these quantities from previous results. This is being investigated by the licensee.
The positive indication of Co-60 tends to support the licensee's conclusion that the source of radioactive material identified in the wells is the BWST, not the water inside the Containment Building.
tiedia interest is expected because of licensee issuance of a press release.
Tne Commonwealth of Pennsylvania has been informed. The NRC does not plan to issue a press release.
This preliminary notification is issued for information only.
The onsite NRC staff will continue investigating the contamination levels in the onsite wells and possible causes and sources of this contamination.
The NRC TMI Program Office received notification of this event from the Director, TMI-2 today at 11:00 a.m.
