4.4.1.3 Isolation Valve Functional Tests Quarterly, remotely-operated Reactor Building isolation valves shall be stroked to the position required to fulfill their safety function unless such operation is not practical during unit operation. The latter valves shall be tested during each refueling shutdown.

4.4.1.4 Refueling Outage Inspection A visual examination of the accessible interior and exterior surfaces of the containment structure and its components shall be performed each refueling out age and prior to any integrated leak rate test, to uncover any evidence of deteri oration which may affect either the containment's structural integrity or leak tightness. The discovery of any significant deterioration shall be accompanied by corrective actions in accord with acceptable procedures, non-destructive tests and inspections, and local testing where practical, prior to the conduct of any integrated leak rate test. Results of the inspection shall be reported to the Commission within 90 days of completion.

4.4.1.5 Reactor Building Modifications Any major modification or replacement of components affecting the Reactor Building integrity shall be followed by either an integratedleak rate test or a local leak rate test, as appropriate,.and shall meet the acceptance criteria of 4.4.1.1.4 and 4.4.1.2.3, respectively.

Bases The Reactor Building is designed for an internal pressure of 59 psig and a steam-air mixture temperature of 2860 F. Prior to initial operation, the con tainment is strength tested at 115 percent of design pressure and leak rate tested at the design pressure; The containment is also leak tested prior to initial operation at approximately 50 percent of the design pressure. These tests verify that the leak rate 'from Reactor Building pressurization satisfies the relationships given in the specification.

The performance of a periodic integrated leak rate test during unit life provides a current assessment of potential leakage from the containment, in case of an accident that would pressurize the interior of the containment.

In order to provide a realistic appraisal of the integrity of the containment under accident conditions, this periodic test is to be performed without pre liminary leak detection surveys or leak repairs, and containment isolation valves are to be.closed in the normal manner. The test pressure of 29.5 psig for the periodic integrated leak rate test is sufficiently high to provide an accurate measurement of the leak rate and it duplicates the preoperational leak rate test at 29.5 psig. The specification provides a relationship for relating the measured leakage of air at 29.5 psig to the potential leakage at 59 psig. The frequency of the periodic integrated leak rate testis normally keyed to the refueling schedule for the reactor, because these tests can best be performed during refueling shutdowns.

The specified frequency of periodic integrated leak rate tests is based on three major considerations. First is the low probability of leaks in the Amendments Nos.

91, 91, & 88 4.4-4

4.8 MAIN STEAM STOP VALVES Applicability Applies to the main steam stop valves.

Objective To verify the ability of the main steam stop valves to close upon signal and to verify the leak tightness of the main steam stop valves.

Specification 4.8.1 Using Channels A and B, the operation of each of the main steam stop valves shall be tested during each refueling outage to demon strate a closure time of one second or less in Channel A and a clo sure time of 15 seconds or less for Channel B.

4.8.2 The leak rate through the main steam stop valves shall not exceed 25 cubic feet per hour at a pressure of 59 psig and shall be tested during each refueling outage.

Bases The main steam stop valves limit the Reactor Coolant System cooldown rate and resultant reactivity insertion following a main steam line break accident.

Their ability to promptly close upon redundant signals will be verified during each refueling outage. Channel A solenoid valves are designed to close all four turbine stop valves in 240 milliseconds. The backup Channel B solenoid valves are designed to close the turbine stop valves in approximately 12 seconds.

Using the maximum 15 second stop valve closing time, the fouled steam generator inventories and the minimum tripped rod worth with the maximum stuck rod worth, an analysis similar to that presented in FSAR Section.14.1.2.9, (but con sidering. a blowdown of both steam generators) shows that the reactor will remain subcritical after reactor trip following a double-ended steam line break.

The main stop valves would become isolation valves in the unlikely event that there should be a rupture of a reactor coolant line concurrent with rupture of the steam generator feedwater header. The allowable leak rate of 25 cubic feet per hour is approximately 25 percent of total allowable containment leakage from all penetrations and isolation valves.
