L PLANT SYSTEMS BASES l

3/4.7.5 ULTIMATE HEAT SINK (UHS)

The limitations on UHS water level and temperature ensure that suf;_elent ecoling capacity is available to either 1) provide normal cooldown of the R$3 f acility, or 2), to mitigate the ef fects of accident conditions within acceptable limits.

The limitations on the maximum temperature are based on providing a 30 R12

,.ay cooling water supply to safety related equipment wichout exceeding their design basis temperature and is consistent with the recommendations of Regulatory Guide 1.27, " Ultimate Heat Sink for Nuclear Plants", March 1974..

The limitations on minimum water level are based on providing sufficient flow to the ERCW serviced heat loads af ter a postulated svent assuming a time-dependent drawdown of reservoir level.

Flow to the r,as sr transient heat loads (CCS and CS heat exchangers) is balance assuming a re ervoir level of R83 elevation 670.

The time-independent he loads (ESF com coolers, etc.) are balanced assuming a reservoir level of..evation 639.

lBR-10 3/4.7.6 FLOOD PROTECTION This specification is deleted.

l 3/4.7.7 CONTROL ROOM FMERGENCY VENTILATION S_YSTEM The OPERABILITY of the control room 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 operations personnel during and following all credible accident conditions. The OPERABILITY of this system in conjunction with control room design provisions is based on limiting the radiation exposure to personnel occupying the control room to 5 rem or less whole body, or

'.ts equivalent. This limitation is consistent with the requirements et General Design Criteria 19 of Appendix "A",

10 CFh 50.

ANSI H510-1975 will be used as a procedural guide for surveillance testing.
