TABLE 4.3-2 (Continued)

TABLE NOTATION (1) Functional testing of the manual actuation circuitry shall include all circuitry necessary to overlap with other functional testing but need not include operation of actuated equipment.

(2) The CHANNEL FUNCTIONAL TEST shall include exercising the transmitter by applying pressure to the appropriate side of the transmitter.

(3) Each logic channel shall be tested at least every other 31 days. Channel Functional

Testing need not include operation of actuated equipment where such operation could adversely affect the safety or operability of the plant or where equipment is normally in its post accident configuration.

(4) Reactor Building Pressure High-High signal only, i

3/4.3 INSTRUMENTATION BASES 3/4.3.1 and 3/4.3.2 R_EACTOR PROTECTION SYSTEM (RPS) AND ENGINEERED SAFETY FEATURES ACTUATION SYSTEM (ESFAS) INSTRUMENTATION The OPERABILITY of the RPS and ESFAS instrumentation systems ensure that 1) the associated ESFAS action and/or RPS trip will be initiated when the parameter monitored by each channel or combination thereof exceeds its setpoint,2) the specified coincidence logic is maintained, of service for testing or 3) sufficient redundancy maintenance, and 4 )is maintained to permit a channel to available for RPS and ESFAS purposes from diverse parameters.

The OPERABILITY of these systems is required to provide the overall reliability, f redundance and diversity assumed available in the facility design for the protection and mitigation of accident and transient conditions. The integrated operation of each of these

! systems is consistent with the assumptions used in the accident analyses.

The surveillance requirements specified for these systems ensure that the overal system functional capability is maintained comparable to the original design standards. The i periodic surveillance test? performed at the minimum frequencies are sufficient to j

demonstrate this capability. The ESFAS Functional Unit CHANNEL FUNCTIONAL TESTS

' shall be performed in accordance with Regulatory Guide 1.22 (Revision 0,1972).

The measurement of response time at the specified frequencies pro'vides assurance that the RPS and ESFAS action function associated with each channel is completed within the time limit assumed in the safety analyses. No credit was taken in the analyses for those channels with reponse times indicated as not applicable.

f Response time may be demonstrated by any series of sequential, overlapping or total channel test measurements provided that such test demonstrate the total channel response time as defined. Sensor response time verification may be demonstrated by either 1) in place, onsite or offsite test measurements or 2) utilizing replacement sensors with certified response times.
