A. Surrunary of Operating Experience for Unit 2 The unit began this reporting period in Mode 5 (Cold Shutdown).

Mode 4 (Hot Shutdown) was entered at 1305 on 12/15/87. On 12/19/87 at 1658 Mode 3 (Hot Standby) was entered. The reactor was taken critical at 1354 on 12/21/87. The unit was synchronized to the grid at 0233 on 12/22/87. The unit operated at power levels of up to 88%

until 12/30/87 when a power reduction to 28% was begun because of steam generator chemistry concerns. The unit operated at approximately 28% for the rest of the reporting period.
