While in Mode 6 with the Reactor Head in p … While in Mode 6 with the Reactor Head in place and fuel in the Reactor Vessel, weld overlay was in progress on the common Decay Heat Suction line from the Reactor Coolant System. The Reactor Coolant System is in a drained condition with RCS level approximately 24 inches above the Hot Leg Centerline. During the first weld pass on the suction line weld located in Containment, the welding operator noticed water seeping from the weld. Visual inspection revealed a small leak. The leakage is too small to quantify the leakrate. Surface examinations prior to welding revealed no abnormal conditions or leakage. Welding operations on this weld have been suspended. Planned Refueling activities continue to defuel the reactor vessel.</br>One train of Decay Heat Removal remains in service providing core cooling. The second train is aligned in standby for Decay Heat Removal. Both Trains of Decay Heat Removal have been declared inoperable due to this leak, however both trains of Decay Heat Removal remain functional.</br>The licensee notified the NRC Resident Inspector.ensee notified the NRC Resident Inspector. +
