MID-CYCLE OUTAGE MAJOR WORK SCOPE - Completed Emergency Diesel Generator A teardown and inspection. - Inspection of the Iso-Phase Bus was performed following an extended period i of elevated temperatures. No major damage was discovered, but some minor repairs were performed. j - Main Turbine Control Valve was slow in opening. Disassembled and discovered there was some galling. Repaired and reassembled. l - Train A Integrated Test Sequence (ITS) and Emergency Diesel Generator A load run. - Replaced Circulating Water intake expansion joints. i 05/22 0000 Ended planned Mid Cycle Outage, began forced outage due to repairs to both i trains of the Containment Spray System. Pump vibration caused welds in some small bore piping branch connections to experience fatigue cracking. Repairs to welds, additional pipe supports and extensive vibration testing is being a j done. 05/31 2400 Unit ended month in MODE 5. f 4 e i 4 W 4 1 4
