Sjogren TELEPHONE (617) 366-9011 X2281 REPORT MONTH July 1979 SU3D!ARY OF OPERATING EXPERIENCES At the beginning of the conth the plant was operating at 497% reactor power limited by the 864 MWe maximum load permitted on the low pres-sure turbine blading.
On July 5 a load reduction to 75% was performed to allow surveillance testing of the turbine valves and also to perform mussel control opera-tions of the Service Water headers. Load was back to N97% on July 7 and remained there for the rest of the month.
