- Unit One was operating in coastdown condliion. I t

On the first the NPDES perrait allowed cooling tower blowdown to in-crease to-300 cfr. 1

t. l On the ninth the norina l and redundant channels of heat iracing for the 1 boric acid storage tank to SI purnp suction failed. This put the Unit in a )

l six hour acilon staternent. Repa i rs were cornp le t ed before the Unit would i have had to s1 art an orderty shutdown.

On the fourteenth an NUE was declared at 0958 due to the failure of the ERCS cornputer in conjunction with a inajor portion of ihe BOP annuriclators 1 being out of service. The ERCS cornputer was returned to service at 0932 which ended the NUE.

l. During the second half of the anonth a stearn generator-tube leak was L detected.- Ii-increased to about 0.0059 pin and then becarne steady. It

! will be repaired-during the outage.

p'

,. Cyc le. fi f teen ref ueling_and snaintenance outage started at 2iOB of the-l' thirty-fi*st when the generator was taken off line. The reactor was non-l . critical at 2307. The outage is scheduled to last 26 to 29 days.
