ESFAS Instrumentation 3.3.2 SURVEILLANCE FREQUENCY SR 3.3.2.5 -------------------NOTE--------------------

Not required to be performed for SLAVE RELAYS if testing would:

1. Result in an inadvertent Reactor Trip System or ESFAS Actuation if accompanied by a single failure in the Safeguard Test Cabinet;

2. Adversely affect two or more components in one or more ESFAS system(s); or

3. Create a reactivity, thermal, or hydraulic transient condition in the Reactor Coolant System.

Perform SLAVE RELAY TEST. 92 days SR 3.3.2.6 ------------------- NOTE--------------------

Verification of relay setpoints not required.

Perform TADOT. 92 days SR 3.3.2.7 -------------------NOTE--------------------

Verification of setpoint not required for manual initiation or interlock functions. I Perform TADOT. 18 months SR 3.3.2.8 ------------------- NOTE-------------------

This Surveillahce shall include verification that the time constants are adjusted to the prescribed values.

Perform CHANNEL CALIBRATION. 18 months North Anna Units 1 and 2 3.3.2-6 Amendment Nos. 244/225
