July 18th 23:30 reduced load in order to perform rod , _.

pattern adjustment. Unit resumed rated flow and rated thermal at 14:30 on 7-10-80.

July 26th 02:18 generator off line 01:10 Rx manually scrammed per IEB 80-17 scram discharge volume analysis proved satisfactory v

July 31th Rx critical at 11:10. Rx auto sertam at 19:37 per IEB 80-17. APRM A and APRM E upscale tripped turbine. Scram discharge volume analysis proved satisfactory. .

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.
