The leakage is several drops per minute; attempts to isolate the leak have been unsuccessful. The associated piping communicates with the reactor coolant system (through the CRD mechanism).</br>Technical Specification 3.4.4 (RCS Operational Leakage), Condition C, was entered at 1302 hours. Condition C requires the unit to be placed in Mode 3 (Hot Shutdown) in 12 hours. At 1616 hours, a Technical Specification required shutdown was initiated on Unit 2.</br>The cause and resolution of the leakage are being pursued.</br>This condition is being reported under 50.72(b)(3)(ii)(A) given the defect is associated with the primary coolant system pressure boundary. This notification is also being made in accordance with 10 CPR 50.72(b)(2)(i) given the initiation of a plant shutdown required by the plant Technical Specifications.</br>The licensee has notified the NRC Resident Inspector.e has notified the NRC Resident Inspector. +
