uni, ABNORMAL OPERATING PROCEDURES l

l OPERATION FROM REMOTE SHUTDOWN PANELS PURPOSE l

Thisprocedure$rovidesoperatorinstructionsinevacuating the Main Contro Room, maintaining hot standby, and attaining cold shutdown from the remote shutdown panels.

This procedure is applicable with or without the availability of offsite power.

This procedure also i

addresses potential or actual component failures which may be induced by Control Room fire events.

SYMPTOMS The Main Control Room is or is about to become inaccessible due to fire, toxic gas, or any other unforeseen reasons.
