NARRATIVE REPORT UNIT 1 June 1st Unit I remained shutdown due to inop RHR valve E11-F017. Shutdown was continued from 5-24.

Valve repaired and returned to service on 6-12.

June 8th Mechanical snubbers, having been locked up, were replaced on 6-8.

June 14th Loas of condense vacuum at 9:06. SJAE was not ejecting non-condensables. Load was reduced and normal vacuum was resumed.

June 15th Reduced load due to condensate demin problems.

Low dP on suction valves ceased. Load brought back up after valve checks.

June 15th Dropped load at 12:20 on 6-16 for control rod pattern adjustment.

June 17th toss of condenser vacuum at 8:00 on 6-17 due to SJAE proportional band being off. Bands adjusted ad SJAE returned to service 17:27 on 6-18.

June 21st Load reduced at 20:50 on 6-21 for weekly turbine testing. Extensive bypass valve checks and CIV checks proved satisfactory.

June 26 Rx scram at 6:49 on 6-26 due to a spike on the PRT relay, falsely indicating high reactor water level. However, startup Jas halted by HPCI failure. The problems were found in HPCI's electrical and hydraulic systems. The high pressure coolant injaction system remains down as o f 6-3 0-80.

There was no single release of radioactivity or single radiation exposure which accounts for more than 10% of the allowable annual values during June of 1980.
