1 of 1 MONTHLY OPERATING ACTIVITIES - FEBRUARY 1987 HIGHLIGHTS

~

The Unit operated the entire month at the nominal 80% power limit,.

(administratively imposed to minimize steam generator tube degradation).

Gross electrical' generation for the month of February was 604,680 MWH.

SUMMARY

1 2-19-87 At 0425 the South Boric Acid Storage Tank was below the Technical Specification Concentration requirement of 20,000 PPM (actual concentration was 19,127 PPM) due to inadvertent dilution caused while isolating the #4 Boric Acid Transfer Pump for repairs to the

' leaking shaft seal. The Action Statement for the boric acid flow path was entered 3 times to correct the concentration, on the following dates and times.

2-21-87 1930-2250 Boric Acid Flowpath inoperable--south storage tank aligned to north hold-up tank.

2-21 1442-1514 Boric Acid Flowpath inoperable--transferred. acid from batch tank to south storage tank increasing level from 71% to 79%.

2-23-87 1824-:900 Boric Acid Flowpath inoperable--transferred batch tank to south storage tank, level remained at 79%.

j 2-23-87._

At 2200, the South Boric Acid Storage Tank Concentration was 21,300 PPM.
