ULTIMATE HEAT SINK (Continued) i The limitations on minimum water level and maximum temperature are based on providing a 30-day cooling water supply to safety-related equipment without exceeding its design basis temperature and are consistent with the i
recommendations of Regulatory Guide 1.27, " Ultimate Heat Sink for Nuclear j
Plants," March 1974.

3/4.7.6 CONTROL ROOM EMERGENCY VENTILATION SYSTEM 1
The OPERABILITY of the Control Room Emergency Ventilation System ensures that:
(1) the ambient air temperature does not exceed the allowable temperature for continuous-duty rating for the equipment and instrumentation cooled by this system, and (2) the control room will remain habitable for j
operations personnel during and following all credible accident conditions.
j Operation of the system with the heaters operating to maintain low humidity using automatic control for at least 10 continuous hours in a 31-day period is sufficient to reduce the buildup of moisture on the charcoal adsorbers and HEPA i
filters. The OPERABILITY of this system in conjunction with Control Room design provisions is based on limiting the radiation exposure to personnel j
occupying the control room to 5 rems or less whole body, or its equivalent.
This limitation is consistent with the requirements of General Design 1
Criterion 19 of Appendix A,10 CFR Part 50. ANSI N510-1975 will be used as a l
procedural guide for in-place surveillance testing. ASTM D-3803-1989 will be l
used as a procedural guide for the laboratory testing of carbon samples, i
1 3/4.7.7 EMERGENCY EXHAUST SYSTEM i
The OPERABILITY of the Emergency Exhaust System assures that radioactive i
materials leaking from the ECCS equipment within the pump room following a LOCA are filtered prior to reaching the environment. Operation of the system l
with the heaters operating to maintain low humidity using automatic control for i
at least 10 continuous hours in a 31-day period is sufficient to reduce the buildup of moisture on the charcoal adsorbers and HEPA filters. The operation of this system and the resultant effect on offsite dosage calculations was assumed in the safety analyses. ANSI N510-1975 will be used as a procedural 4
guide for surveillance testing. ASTM D-3803-1989 will be used as a procedural l
guide for the laboratory testing of carbon samples.

BASES removal capability. With the reactor vessel heat removed and at least 23 feet of water above the reactor vessel flange, a large heat sink is available for core cooling. Thus, in the event of a failure of the operating RHR loop, adequate time is provided to initiate emergency procedures to cool the core.
3/4.9.9 CONTAINMENT VENTILATION SYSTEM The OPERABILITY of this system ensures that the containment purge penetrations will be automatically isolated upon detection of high radiation
)
levels within the containment. The OPERABILITY of this system is required to restrict the release of radioactive material from the containment atmosphere to the environment.
I f
3/4.9.10 and 3/4.9.11 WATER LEVEL - REACTOR VESSEL and STORAGE POOL l
The restrictions on minimum water level ensure that sufficient water i
depth is available to remove 99% of the assumed 10% iodine gap activity j
released from the rupture of an irradiated fuel assembly. The minimum water l
depth is consistent with the assumptions of the safety analysis.
i 3/4.9.12 SPENT FUEL ASSEMBLY STORAGE I
The restrictions placed on spent fuel assemblies stored in Region 2 of the spent fuel pool ensure inadvertent criticality will not occur.
3/4.9.13 EMERGENCY EXHAUST SYSTEM The limitations on the Emergency Exhaust System ensure that all radioactive materials released from an irradiated fuel assembly will be filtered through the HEPA filters and charcoal adsorber prior to discharge to the atmosphere. Operation of the system with the heaters operating to maintain low humidity using automatic control for at least 10 continuous hours in a 31-day period is sufficient to reduce the buildup of moisture on the adsorbers and HEPA filters. The OPERABILITY of this system and the resulting iodine removal capacity are consistent with the assumptions of the safety analyses. ANSI N510-1975 will be used as a procedural guide for surveillance testing. ASTM D-3803-1989 will be used as a procedural guide for the laboratory testing of charcoal samples.
