SUMMARY
OF OPERATING EXPERIENCE UNIT TWO MAY, 1980 5-1 to 5-12 Unit Two started the month operating at a power level of 720 MWe.
On May 12, at 1011, a spurious signal developed on the main steam high radiation monitors, resulting in a Group I isolation and subsequent reactor scram.
5-12 to 5-18 Unit Two commenced its scheduled main-tenance outage at 2011 on May 12, 1980 to replace "B" recire. pump seals.
5 to 5-22 The Unit was placed back on line at 2047 l
on May 18 and reached a power level of 630 MWe when the inadvertent jarring of an instrument rack by Mechanical Main-4 l
tenance resulted in the Unit scramming on reactor low level at 1137 on May 22.
1 5-22 to 5-31 The Unit was again placed on line at 2226 and operated the remainder of the month at an average power level of 621 MRe, with a capacity factor of 64% for the entire month.
