v OPERATICNS SGNARY Septmoer 1980 At the beginning~of the reporting period, the plant was operating at 504 MNe. On Septemoer 18 tne reactor was shut dcwn as a result of increasing drywell unidentified leak rate. 'Ihe leak rate was e anciad by a leaking drain line on a feedwater check valve. After empletion of minor maintenance the plant was restarted on September
- 23. 'Ihe generator was placed on line at 2011 on September 23. 'Ihroughout the rest of the reporting period the plant power level was raised to rated 1 cad ard operated at this level.
During the nonth, tw DmLn.gency Conditions occurred. Ch Septaber 8, a temporary Class I amLn.gency occurred when an air pt.ge valve in the distribution Pandar caused a chlorine leak. On September 29, a Class II Emergency occurred when a discharge hose frcm the Floor Drain Sample Tank Processing Unit in the truck bay of the Old Radwaste Anilaing ruptured. About 5 gallons of water ran under the roll-up door and across the loading dock to the grourd.
Five Reportable Occurrences and tw Non-Ibutine Envi-ental Operating Reports were identified during September.
RC# 80-40 occurrec on September 4 when a Hydraulic Shock and Sway failed functional testing.
rot 80-41 occurred on September 5 when Core Spray System II was renoved frcm service for corrective maintenance to repair a leak arourd a thraadad fitting.
R04 80-42 occurred on September 11 wran, during surveillance testing, Drywell High Pressure Switch IP15 for the Contairmant Spray System was found to have a setting less conservative than Technical Specification requmanents.
RO# 80-43 occurred on September 25 when, during surveillance testing, Reactor Triple Icw Sensor RE 18D was found to have a setting less conservative than W hni< 1 Specification requirements.
rot 80-44 occurred on Sept aber 30 when the h a.nt initiation of the fire protection system caused Core Spray System I to be considered inoperable.
NRECR# 80-7 occurred on Septeber 1, 2, and '4 when~ Dilution Pumps 1-1 and 1-3 tripped and two reserve puxps could not be placed in service within the required fifteen minute period. In each instance, tPa temperature at the U.S. Route 9 bridge exceeded 87"F.
