Time elements on the ground relays were extended from .25 seconds to .5 seconds I

Nand other corrective actions are to be implemented as conditions permit.

(see LER 85-002) 1/17/85 58.33 3 85-006 EB CKTBRK A Scram occured at 100% power due to an accidental h5-03 F G trip of a feeder breaker and the resultant loss of "A" RPS Bus while a h Scram existed on the opposite

. RPS channel due to troubleshooting an APRM down ..

scale alarm.

~~~

gave signal that generator breaker was open when in actuality, it remained closed. The signal was subsequently shifted to a more

\ reliable microwave channel. (seeLER85-005) 15-05 1/31/85 F 16.02 A 3 LATER EB RELAYX F Generator tripped from 100% power as a result of inadvertant operati6n of a unit lockout relay with the resultant tripping scheme causing a partial loss of off site power. The cause of-trip was investigated, transformers were tested and modifications to relays were implemented to prevent similar future occurances.
