PWR/W-4-LP
Subject: SMALL UNMONITORED RELEASE OF RADIOACTIVITY INTO NIANTIC BAY
Reportable Event Number: 35219
Discussion:
On January 4, 1999, a 1 - 2 gallon per minute leak in the Unit 3 "A"
waste test tank (WTT) was discovered. However, by the time the leak was
found and isolated, approximately 1,050 gallons of water containing low
levels of tritium and trace amounts of other radionuclides had leaked
into the yard drain system. Heavy rain at that time carried the slightly
contaminated water to Niantic Bay. A berm, which was constructed around
the WTT about a month ago, failed to contain the leak.
The 21,000 gallon WTT is located outside of the waste disposal building
on the Northwest side of the Unit 3 yard. A total of 0.0217 curies of
radionuclides (predominately tritium) eventually reached Niantic Bay.
This amount represents a whole body dose of 2.2E-07 millirem to the
maximum exposed member of the public. Later that day, the remaining
contents of the tank (over 15,000 gallons) were released to Niantic Bay
through the normal release path. The licensee is investigating why the
berm did not contain the leak, and is preparing to line the berm with an
impermeable membrane.
Regional Action:
The resident inspectors are following the licensee's actions.

for Millstone Unit 2 to restart; the licensee is currently limited to

(Independent Corrective Action Verification Program ICAVP and Employee
Concerns), and one open Confirmatory Action Letter (Operator Licensing)
at Millstone. Additionally, a 40500 Team Inspection and a Readiness
Assessment Team Inspection will occur prior to the Commission vote on
restart.
