SURVEILLANCE RE UIREMENTS 4.8.4.1 The above noted primary and backup containment penetration conductor overcurrent protective devices (except fuses) shall be demonstrated OPERABLE:

'a ~

At least once per 18 months:

1.

By verifying that the medium voltage (4-15 kV) circuit breakers are OPERABLE by selecting, on a rotating basis, at least 10X of the circuit breakers of each voltage level, and performing the following:

(a)

A CHANNEL CALIBRATION of the associated protection

relays, and (b)

An integrated system functional test which includes simulated automatic actuation of the system and verifying that each relay and associated circuit breakers and control circuits function as designed.
