1 OPERATING SUMUJtY ,

I The Unit was in a cold shutdown the entire month by order of the NRC. The i pri=ary system was par.;ially drained and open to the containment atmosphere te per=it OTSG tube inspection / repair work. Core cooling was provided by the decay heat re= oval syste=.  ;

L I t MMOR SAFETY REl.ATED MAINTENANCE i

The following =ajor =aintenance ite=s were perfor=ed during the month:

Refueling surveillance program for testing of hydraulic snubber started. Snubbers (10) were re=cved and transported to the test stand. Nine (9) snubbers were tested satisfactorily, and the re=aining one (1) vill be tested in March af ter an adapter is =ade for testing the snubber.

! Work progressed on the OTSGs. The B&W portion of tube plugging to plug tube sheet formations fro = which the sa=ples have been removed was performed. This included identifying tubes to be plugged, weld plugging the upper tube section, and explosively plugging the lower

{ section of the tubes. Four sa=ples in OTSG-B and fifteen sa=ples in OTSG-A were removed and plugged. The cause of the proble=s continue to be under investigation. LER 81-013 will provide further infor=ation. PTeparations are in progress for Westinghouse tube plagging of 46 tubes in OTSG B and 91 in OTSG A in March.

SUMMARY

The Unit was in a cold shutdown the entire month by order of the NRC. The

primary system was partially drained and open to the containment atmosphere i to permit OTSG tube inspection / repair work. Core cooling was provided by tne decay heat removal system.

MAJOR SAFETY RELATED MAINTENANCE The following major maintenance items were performed during the month:

Refueling surveillance program for testing of hydraulic snubber

-started. Snubbers (10) were removed and transported to the test stand. Nine (9) snubbers were tested satisfactorily, and the remaining one (1) vill be tested in March af ter an adapter is made for testing the snubber.

Work progressed on the OTSGs. The B&'.? portion of tube plugging to I.

plug tube sheet formations from which the samples have been removed was performed. This included identifying tubes to be plugged, weld plugging the uppet tube section, and explosively plugging the lower

section of the tubes. Four samples in OTSG-B and fifteen samples in OTSG-A were removed and plugged. The cause of the problems continue to be under investigation. LER 81-013 will provide further information. Preparations are in progress for Westinghouse tube plugging of 46 tubes in OTSG B and 91 in OTSG A in March.
