BOSTON EDISON COMPANY PILGRIM NUCLEAR POWER STATION DOCKET N0. 50-293 Operational Surmary for August 1983 The month started with a continuation of the outage to repair the M0-1301-16 RCIC valve (Ref. LER 83-44/03L-0. The unit was started up on 8/2/83 with a return to full power on 8/3. On the same day, the reactor building and turbine building closed cooling water heat exchanger were backwashed.
On 8/4 power was reduced for a rod pattern change with a return to full power on the morning of 8/5. Also on 8/5, control rod 10-31 was electrically disarmed because of continuing direction control problems (Ref.: LER 83-046/03L-0).
The unit remained at 100% power until 8/10 when the unit scrammed during a high risk surveillance test because of a false low water level signal.
During the startup, salt buildup on the switchyard insulators was washed off and condenser backwashing was required because of an ocean storm.
On 8/13 full power was attained and remained at that level until 8/26 when power was reduced to approximately 50% for condenser backwash and scheduled maintenance. On 8/27 the unit was returned to full power and remained at full load thru the end of the month.
