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.
