PCN-485 ATTACflMENT "G" PROPOSED BASES UNIT 2

CRIS B 3.3.9 BASES SURVEILLANCE SR 3.3.9.5 REQUIREMENTS (continued)

Every 18 months, a CHANNEL FUNCTIONAL TEST is performed on the manual CRIS actuation circuitry.

This test verifies that the trip push buttons are capable of opening contacts in the Actuation Logic as designed, de-energizing the initiation relays and providing Manual Trip of the function.

The 18 month Frequency is based on the need to perform this Surveillance under the conditions that apply during a plant outage and the potential for an unplanned transient if the Surveillance were performed with the reactor at power. Operating experience has shown these components usually pass the Surveillance when performed at a Frequency of once every 18 months.

~

This Surveillance ensures that the train actuation response times.are less than or eaual to the maximum times assumed in the analyses. A time limit to isolate the control room is needed to ensure compliance with 10 CFR 50 Appendix A General Desian Criterion 19.

The 18 month freauency is based upon plant operatina experience, which shows that random failures of instrumentation components causina serious response time dearadation, but not channel failure, are infreauent occurrences. The response time is tested from the module input:

i.e., the radiation detector response is not measured.

Testina of the final actuatina devices is included in the Surveillance.

Response time testing accepthnce criteria are included in Reference 4.
