CONTAINMENT SYSTEMS BASES 3/4.6.4 VACUUM RELIEF Vacuum relief breakers are provided to equalize the pressure between the drywell and suppression pool and the suppression pool and reactor building..
This system will maintain the structural integrity of the containment under conditions of-large differential pressures.
1 The vacuum breakers between the drywell and the suppression pool must not be j
inoperable in the open position since this would allow bypassing of the I
i suppression pool in case of'an accident. There are an adequate number of valves to provide some redundancy so that operation may continue with no more than 2 vacuum breakers inoperable and secured in the closed position.
Each set of vacuum relief valves between the suppression chamber and reactor building provides 100% relief, which may by required in the unlikely event that* negative pressures develop in the primary containment.
The Nitrogen Backup System provides backup motive power for these suppression pool-reactor building vacuum breakers on a loss of instrument air.
The normal non-interruptible instrument air system for these vacuum breakers is designed as s'Setemic Class I system supplied by air compressors powered from the emergency buses. The Nitrogen System serves as a backup to that air system and thus the loss of the Nitrogen System, or portions thereof, does'not make the vacuum breakers inoperable. The design allows for the out of service times in Actions b and c.
The Nitrogen Backup System is added to the Suppression Pool-Reactor-Building Vacuum Breaker specification to satisfy NRC concerns relative to 10 CFR 50.44(c)(3) as addressed in the Brunswick. Safety Evaluation Report dated October 30, 1986 concerning Generic Letter 84-09.
Pressurization to 1130 psig assures sufficient system capacity to provide 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of operation with design valve actuation.and' system leakage.
3/4.6.5 SECONDARY CONTAINMENT Secondary containment is designed to minimize any ground level rett h e of radioactive-material which may result from an accident. The reactu building rprovi-des secondary containment during. normal operation when the drywell is sealed and.in service. When the reactor is shut down, or during refueling, the.drywell may be open and the reactar building then becomes the primary containment.
Establishing and maintaining a vacuum in the building with the standby gas treatment system, once per 18 months, along wit.h the surveillance of the valves, is adequate to ensure that there are no violations of the integrity of the secondary containment.
3/4.6.6 CONTAINMENT ATMOSPHERE CONTROL The OPERABILITY of the containment iodine filter trains ensures that sufficient icdine removal capability will be available in the event of a LOCA. The reduction in containment iodinn inventory reduces the resulting l
