II. Monthly Report for Byron Unit 2 for the month of' November 1987 J A. Sununary of Operating Experience for' Unit 2 jr v (

The unit began this reporting period in Mode 1 at 94% power.. The unit operated,at power levels of up.to 94% until 11/20/87 when power was deceased dui to high steam generato: cation conductivity. On 11/21/87 at 0328 the load reduction was completed at 26% reactor power. The condition was corrected and poweri4as at 88% by 0700 on.

11/24/87. At 1740 on 11/25/87 a power reducti'on - for a s'cheduled .

surveillance outage was begun. 'On 11/26/87 at 0200 the generator was taken off line. At 2025 on 11/26/87 Mode 5 (Cold Shutdown) was .

entered. The unit remained in mode 5 for the rest of the;r'eporting. . -(
