APPLICABILITY: MODES 1 and 2.
ACT.10N:
With one Hydroger. Recomb 4er System inoperable, restore the inoperable system to OPERABLE status within 30 days or be in at least H0T STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

CONTAINMENT SYSTEMS BASES
.C@TAINMENT VENTILATION SYSTEM (Continued) fore, the SITE B0UNDARY doso guidelines of 10 CFR 400 would not be exceeded in the event of an accident durie containment PURGING operation.
Leakage integrity tests with a maximum allowable leakage rate for contain-ment-purge supply and exhaust supply valves will provide early indication of resilient material seal degradation and will allow opportunity for repair before gross leakage failures could develop.
The 0.60 L leakage limit of Specification 3.6.1.2b. shall not be exceeded when tne l,akage rates determined e
by the leakage integrity tests of these valves are added to the previously determined total for all valves and penetrations subject to Type B and C tests.
3/4.6.2 DEPRESSURIZATION AND COOLING SYSTEMS 3/4.6.2.1 CONTAINMENT SPRAY SYSTEM The OPERABILITY of the Containment Spray System ensures that containment depressurization and cooling capability will be available in the event of a LOCA or steam line break.
The pressure reduction and resultant lower contain-ment leakage rate are consistent with the assumptions used in the safety analyses ~.
The Containment Spray System and the Containment Cooling System both provide post-accident cooling of the containment atmosphere.
However, the Containment Spray System also provides a mechanism for removing iodine from the containment atmosphere and therefore the time requirements for restoring an inoperable Spray System to OPERABLE status have been maintained consistent with that assigned other inoperable ESF equipment.
-3/4.6.2.2 RECIRCULATION FLUID-PH CONTROL SYSTEM The operability of the recirculation fluid pH control system ensures that there is sufficient trisodium phosphate available in containment to-guarantee a sump pH of 27.0 during the recirculation phase of a postulated LOCA. This pH level is required to reduce the potential for chloride induced stress corrosion of austenitic stainless steel and assure the retention of iodine in the recirculating fluid. The specified amounts of TSP will result in a recircula-tion fluid pH between 7.0 and. 9.5.
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.
STPEGS has three groups of Reactor Containment Fan Coolers with two fans I
in each group (total-of six fans).
Five fans ere adequate to satisfy the safety requirements including single failure.
