CONTADMENT SYSTIUS BASES 3/4.6.3 CDNTAINMENT ISOIATION VALVES The OPERABILTIY of the containment isolation valves ensures that the containment atmosE ere will be isolated frm the outside enviroment in the h
event of a mlease of radioactive material to the containment atmosphere or pressurization of the containment. Containment isolation within the time limits specified ensures that the release of radioactive material to the environment will be consistent with the assunptions used in the analyses for a LOCA. Containment Isolation Valves arri their required isolation times are addressed in the FSAR.
3/6.6.4 COME0STIBLE GAS CONIROL The OPERABIIIIY of the equipment and systems required for the detection and control of hydrogen gas ensures that this equipment will be available to raintain the hydrogen concentration within containment below its flammable limit durinJ pcst-IDCA conditions. The purge system is capable of controlling the expected hydrogen generation associatal with 1) zirconium-water reactions, 2) radiolytic decmposition of water and 3) corrosion of metals within containment. These hydrogen control systems are consistent with the r-ndations of Regulatory Guide 1.7, "Control of Ombustible Gas Concentrations in Containment Following a IDCA", March 1971.
