Exhibit I - Same Source (9/77) 11-01her (Explain)
OPERATICtG SLFNARY August 1980 At the beginning of the reporting period, the plant was placed in cold shutdown for a maintenance outage. Pepairs were ccupleted and a reactor startup was initiated on 8/4. During startup high flux in Range 9 of the IBM's caused a reactor scram. The reactor was restarted on 8/5 and the generator was put on the line at 1128. Ch 8/6 a reactor shutdown was initiated due to Tbrus Oxygen concentration greater than 5%.
The situation was renedied and the shutdown terminated after 30 minutes.
Later on 8/6, load was temporarily reduced 100 me due to high drain tank levels. On 8/12 load was again temporarily reduced due to flash tank problems. On 8/15, another plant shutdown was initiated due to a loss of the stack gas sample pump. The shutdown was tendnated after 19 minutes.
Throughout the reporting period, load was limited by condensate denineralizer differential pressure limitations.
Six Reportable Ctcurrences and twa Non-Routine Environwntal Operating Reports were identified during the month:
RO# 80-33 occurred on August 6 when the oxygen concentration in the Primary Cbntamnent exceeded 5%.
RO# 80-35 was identified on August 14 when IM Pressure Switches IP15 A&D were found to have settings less conservative than Technical Specification requirenents.
RO# 80-36 occurred on August 15 when the Stack Gas Sanple Pung; failed due to a clogged filter.
RO# 80-37 occurred on August 19 when SBGTS II failed to operate properly during mrveillance testing.
RO# 80-38 was iden'.ified on August 26 when Reactor Triple Iow Water Ievel Sensor RE18B was found to have a setting less conservative than Technical Spec.i.fication requ2renents.
RO# 80-39 was identified on August 29 when MSL Iow Pressure Sensors RE23B&D were found to have settings less conservative than Ibchnical Specification requirenents.
NREDR# 80-5 occurred on August 8, 9, 10, 11, 12 when, on ten separate occasions, a dilution pump tripped and could not be restarted within the requiral 15 minutes. During each occurrence discharge water temperature exceeded 87.0 F at the U.S. Ibute 9 bridge.
NREOR# 80-6 occurred on August 11 when condenser discharge temperature exceeded 106 F on tm occasions.
