NARRATIVE
SUMMARY
OF OPERATING EXPERIENCES i 1 l !
j LAt the beginning of the month the unit was at 100% power. :
d On July 8th, power was reduced to 75% for turbine valve and excess flow 4 check' valve testing, and mussel control. The unit was returned to 91% ;
power pending repair of the'govenor valve control circuitry. f
'On July 9th, the unit was returned to 100% power.
M.Y.. received an amendment to plant Technical Specifica , l On July 10th, {
.tiens: increasing thermal power rating from 2630 MWth to 2700 MWth. 1 On July 20th, M.Y. began its power escalation from 2630 to 2700 MWth.
On July;21st, M.Y. reached a steady state power level of 2640 MWth which rspresents 98% of the new rated power level.
Tho unit was maintained at'98% power for the remainder of the month.
