Replaced the valve diaphragm.

M-2 Air operated containment isolation valve for No. 2 S/G blowdown, DCR-320 was leaking.

Replaced the gaskets and had valve tested.

M-3 Air operated containment isolation valve for No. 4 S/G blowdown, DCR-340 valve stem was improperly connected to the operator.

Repaired valve stem threads, replaced the stem to operator coupling, repacked the valve and had it tested.

C&I-l Radiation Monitoring System Channel R-12, containment radio gas monitor would alarm during periods and displayed several spikes in the indication.

The detector tube and the electronics enclosure were replaced with spares.

A calibration was performed and surveillance test was performed to verify operability.

C&I-2 Shutdown Bank A of the control rods would not move when the control system required the rod movement. The cause of the trouble was found to be the failure of the supervisory buffer memory card. The card was replaced with a spare and the system was returned to service and functioned as required.

C&I-3 Radiation Monitoring System Channel R-15, steam jet air ejector monitor would periodically produce high alarms.

During the testing of the drawer assembly it was determined the problem resulted from the electronics en-closure at the detector location. The electronics enclosure was replaced with a spare and a channel calibration was performed.
