022 791120 F 219 A 3 N/A ED El. ECON The reactor scrammed as a result of

, the loss of power to emergency husses El and E2. Offsite power was inter-rupted to El and E2 due to degraded switchyard voltage. The degraded switchyard voltage condition occurred when the generator exciter was placed

. In manual voltage control to clear an over-excitation annunciator in accord-ance with the Annunciator procedure.

Apparently an unstable system voltage condition caused a further deterio-ration of switchyard voltage when the ,

. exciter was taken out of automat ic voltage control. The outage was extended as a result of the repairs to t'he uninterruptible power supply (UpS) system which failed when power was lost to buses El and E2.

SUMMARY

BRUNSWICK NO. 2 Brunswick Unit No. 2 operated at a 80.8% capacity factor for the month of November. The following power changes and shutdowns occurred during the month:

November 9: Power was reduced to repair condenser waterboxes A-South, B-North.

November 19: Reactor scra=med because of an instrument rack being jarred by janitorial personnel.

For = ore information on individual outages, see the Unit Shutdowns and Power Reductions Logs (Appendix D) for the month of November.

Availability factor for the month was 92.8%.

There are 132 BWR spent fuel assemblies and 98 PWR spent fuel assemblies stored in the BSEP 42 spent fuel pool.

Due to a transcribing error, the number of PWR spent fuel assemblies stored in BSEP 42 should have read 91 instead of 84 spent fuel assemblies for the month October 1979.
