UNIT 1 July 1st Reactor remained shutdown due.to failure of high pressure coolant injection system from 6-26-80
'I to 7-7-80
.. ~
July'7th Crack was discovered in RWCU return line-to feedwater.
Crack was repaired and reactor went
-I critical at 09:20 on 7-10-80 July 10th 11:04 Rx scram on APRM A and APRM E upscale trip.
Rx went critical. at 23:40 on 7-10-80 July 12th At 07:27 reduced load in order to perform rod pattern adjustment July 19th 21:25 reduced load in order to perform control valve tests y '
July 20th Unit off line at 15:18; Rx manual scram at 19:27 per IEB #80-17.
Scram discharge volume analysis (pressure,
- temp, and valve testing) proved satisfactory.
Unit remained down while performing drywell fan maintenance.
Rx went critical at 14:52 on 7-25-80 July 26th Unit on line at 14:06, Rx auto scram at 18:38 turbine tripped on low Rx water level, loss of feedpump.
HPCI test performed, HPCI performance found satisfactory July 27th 00:05 Rx critical, generator on line at 05:35 July '2 8th 19:30 reduced load in order to per ferm rod pattern adjustment There was no single release of radioactivity or single radiation exposure which accounts for more than 10% of the allowable annual value's during July of 1980.
