UNIT 2 DECLARED AN UNUSUAL EVENT BASED ON IDENTIFIED REACTOR COOLANT SYSTEM (RCS) LEAKAGE > 10 GPM
At 1145EST on 1/19/01, Unit 2 declared an Unusual Event based on RCS leakage of 10.0015 gpm. The location of the leakage is the "C" loop unit bypass valve 2-RC-MOV-2587. The leakage is through the packing leakoff line to the primary drain tank. There are minor elevated rad levels in the stripper cubicle where the drain tank is located. HP personnel are monitoring this area. The licensee expects to have Unit 2 offline by 1600EST today. Tech Spec 3.4.6.2 requires that identified RCS leakage be less than 10 gpm or that the unit be placed in cold shutdown by 0300EST on 1/21/01. The licensee anticipates completing repairs while in mode 3 at which time they will exit the Unusual Event.
The licensee informed both state/local agencies and the NRC resident inspector.
* * * UPDATE AT 2314 on 1/19/01, BY BROWN, RECEIVED BY WEAVER * * *
2-RC-MOV-2587 was opened electrically and manually backseated. This reduced RCS leakage below 10 gpm and the unusual event was terminated at 2323EST. The plant is stable in mode 3 and the licensee is developing a plan to repair the valve. Repairs may be done with the plant in mode 3. The licensee will notify the NRC resident inspector.
The operations center notified the RDO (Rodgers); EO (Leeds); FEMA (Steindurf)
