NRC hionthly Operations Summary c-

Peach Bottom Atomic Power Station October 1990 -
Unit 2 The unit began the month at 80% power in support of maintenance work on the 2C condensate pump, and dropped to 60% the same day for wrk on the 'A2* and *B2' waterboxes. Repairs were made and the Unit was returned to nominal 100% power on October 4.
During the month, minor repairs were maic with no significant problems, On October 20, a load drop began for c antrol rod adjustment which was competed by October 24. The unit was again returned to 100% power whe c it remained for the rest of the month.
J'oltl The unit began the month at 100% power, During the week of October 15, acceptance testing was completed for the new process computer. Preparations for th'c mid-cycle outage began on October 26, and the unit was manually shut down for the outage at 1:30 A.ht, on October 27.
The Offgas system experienced a recombination of hydrogen and oxygen in the aftercondenser rather than the recombiner. When operators attempted to swap steam jet air ejectors, recombination was forced back into the recombiner and the process stabilized. The cause remains the subject of investigation. This condition is not uncommon for a two unit BWR, it appears that the flame or combustion flashes back on pressure wave during low pressure condition. G.E. S.I.L 246 references this condition almost exactly as experienced.
