The OPERABILITY of these systems is required to provide the overall reliability, redundancy, and diversity assumed available in the facility design for the protection and mitigation of accident and transient conditions.
The Integrated vperation of each of these systems is consistent with the assumptions used in the safr / analyses. The Surveillance Requirements specified for these systems ensure that the overall system functional capability is maintained comparable to the original design standards. The ;eciodic m surveillance tests performed at the minimum frequencies are sufficient to demonstrate this capability, and Supplement 1 The Engineered Safety Features Actuation System Instrumentation Trip e peints specified in Table 3.3 4 are the ncminal values at which the bistables are set for each functional unit. A Setpoint is considered to be adjusted consistent with the nominal value when the "as measured" Setpoint is within the band allowed for calibration accuracy. Specified surveillanc.e intervals and surveillance and maintenance outage times have been determined in accordance withWCAP-10271?"EvaluationofSurveillanceFrequenciesandOutofService times for the Reactor Protection Instrumentation System," supplements to that report, and the NRC's Safety Evaluation dated February 21, 1965. Surveillance intervals and out of service times were determined based on mainta' ing and an appropriate level of reliability of the Reactor Protection Safety features instrumentation, 7 tem 105e % a 4 Engineered tion of the RWST and VCT valves (Notes 3 and 4) are based o the non LOCA safety analysis. These analyses take credit for injection of borated water from the RWST. Injection of borated water is assumed not to of the RWST charging pump suction valves. occur until the VCT charging pum When the sequential operation of the RWST and VCT valves is not includeo in the response times (Note 7), the values specified are based on the LOCA anal);es. The LOCA analyses take credit for injection flow regardless of the source. Verification of the response times +
