CONTAINMENT SYSTEMS BASES I 3/4.6.2.3 CONTAINMENT COOLING SYSTEM The OPERABILITY of the Containment Cooling System ensures that: (1) the containment air temperature will be maintained within limits during normal operation, and (2) adequate heat removal capacity is available when operated in conjunction with the Containment Spray Systems during post-LOCA conditions.

3/4.6.3 CONTAINMENT ISOLATION VALVES The OPERABILITY of the containment isolation valves ensures that the con-tainment atmosphere will be isolated from the outside environment in the event of a release of radioactive material to the containment atmosphere or pressuri- l zation of the containment and is consistent with the requirements of General Design Criteria 54 through 57 of Appendix A to 10 CFR Part 50. Containment isolation within the time limits specified for those isolation valves designed to close automatically ensures that the release of radioactive material to the environment will be consistent with the assumptions used in the analyses for a LOCA. The containment isolation valves associated with the containment hydrogen monitors may be opened on an :ntermittent basis under administrative co-trol. Since the controls for these valves are located in the main control room, which is continuously manned an operator will be available to ensure rapid isolation if necessary. AlIstofcontainmentisolationvalvesisprovidad in Table 16.3-4 of the VEGP FSAR.

k 3/4.6.4 COMBUSTIBLE GAS CONTROL l The OPERABILITY of the equipment and systems required for the detesteen l and control of hydrogen gas ensures that this equipment will be available to <

maintain the hydrogen concentration within containment below its flammable j limit during post-LOCA conditions. Either recombiner unit is capable of con- (

trolling the expected hydrogen generation associated with: (1) zirconium-water i reactions, (2) radiolytic decomposition of water, and (3) corrosion of metals {

within containment. These Hydrogen Control Systems are consistent with the I recommendations of Regulatory Guide 1.7, " Control of Combustible Gas Concen-trations in Containment Following a LOCA," Revision 2, November 1978.

The Hydrogen Mixing Systems are provided to ensure vaquate mixing of the containment atmosphere following a LOCA. This mixing I s on will prevent l

localized accumulations of hydrogen from exceeding the #! wtable limit.
