NARRATIVE

SUMMARY

OF OPERATING EXPERIENCES i

1 l

j LAt the beginning of the month the unit was at 100% power.

d power was reduced to 75% for turbine valve and excess flow 4

On July 8th, and mussel control.

The unit was returned to 91%

check' valve testing, 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

.tiens: increasing thermal power rating from 2630 MWth to 2700 MWth.

{

On July 10th, 1

On July 20th, M.Y. began its power escalation from 2630 to 2700 MWth.

M.Y. reached a steady state power level of 2640 MWth which On July;21st, rspresents 98% of the new rated power level.

Tho unit was maintained at'98% power for the remainder of the month.
