0 PLANT SYSTEHS BASES 3/4. 7. 1. 6 STANOB FEEOWATER SYSTEH The purpose of this specification a the supporting surv i llance require-ments is to assure o erabi lit of the n-safety grade Standby<Feedwater System.

The Standb ee wa er ys em cons>s s of commercial grade components designed and constructed to industry and FPL standards of this ciass of equipment located in the outdoor plant environment typical of FPL facilities system wide. The system is expected to perform with high reliability, i.e., comparable to that typically achieved with this class of equipment. FPL intends to maintain the system in good operating condition with regard to appearance, structures, supports, component maintenance calibrations etc.

The function of the Stand y~ ee wa er s em or OPERABILITY determinations is that it can be used as a backup to the Auxiliary Feedwater (AFM) System in the event the AFW System does not function properly. The system would manuall started, ali ned and controlled by the o erator when needed ~e

~~Sr+

A supply of 60,000 gallons from the Demineralized Mater Storage Tank for Reve the Standby Feedwater Pumps is sufficient water to remove decay heat from the reactor for six (6) hours for a single unit or two (2) hours for two units.

This was th basis used for requiring 60,000 gallons of water in the non-safety grade Demine lized Mater Storage Tank and is judged to provide sufficient time for restoring Storage Tank.

( i~ sea~.l d<<ve< s The OPERABILITY of the Component Cooling Mater System ensures that suf-ficient cooling capacity is available for continued operation of safety-related equipment during normal and accident conditions. The redundant cooling capacity of this system, assuming a single active failure, is consistent with the assumptions used in the safety analyses. One pump and two heat exchangers provide the heat removal capability for accidents that have been analyzed.

3/4. 7. 3 INTAKE COOLING MATER SYSTEM The OPERABILITY of the Intake Cooling Mater System ensures that sufficient cooling capacity is available for continued operation of safety-related equip-ment during normal and accident conditions. The design and operation of this system, assuming a single active failure, ensures cooling capacity consistent with the assumptions used in the safety analyses.

3/4.7.4 ULTIMATE HEAT SINK The limitations on the ultimate heat sink temperature ensure that sufficient cooling capacity is available either: (1) to provide normal cooldown of the facility or (2) to mitigate the effects of accident conditions within acceptable 1 imi ts.

In addition, an inspection will be performed on the diesel at'least once every 18 months in accordance with procedures prepared in conjunction with its manufacture's recommendations for the diesel's class of service. This inspection will ensure that the diesel driver is maintained in good operating condition consistent with FPL's ovezall objectives for system reliability.
