- "5,4 Because of the importance of SW System, prompt return of pumps to service is paramount. Turbine Building and Reactor Building Closed CoolingWater Systems are dependent upon the SW System to remove heat from equipment they serve. If Service Water SYstem pressure is indicating < 38 psig in the Control Building Basement, there is inadequate system pressure to provide adequate cooling to the REC heat :exchangers, Diesel Generators, or SW backup cooling to REC. ýFor this reason. the reactor is shut down,.
depresgurized. and reactor rtcirculation pumps tripped. This procedure outlines actions to be taken by i$.at ion persdnniel to maintain reactor safety._
15.5 Depending upon the actual rate ofrAver Uevel decrea*te. the plant will be in process of shutting down or will be ihuti down pnoru'.eiAching 865'. In any event., it is'desiramle to inantain the condenser as heatcooled sink for downcooldown.,

5.8 Signific6antdifferenca.; betwtq-n river level and E Bay level may exist at low river levels due to flow losSes over and around the.end of the guide wall. These flow losses are much higher when C(W1pumps brt, operatmgnbecause of their high capacity compared t-o'SW pumps. Thertifume. stopping CW pumps may restore low E Buy level.

I._r*7 L6 _1.7 .z*LL-."* -- :.:z S-5.1'TAie guidance at river water levels below 863' is beyond design basis. In certain situations, getting flow past the guide wall and into E Bay may not be a Aroblem. If providing water to E Bay atxriver levels down to 861' is not a problem, then running two throttled SW pumps may be better than r'uning one unthrottled since cavitation is worse as individual pump flow .increases.
This is demonstrated by the ch'at on Atachment 3.
5.11 As 860.5' level is approached. SW pump capacit, (without cavitation) is reduced due to less than design submergence. SW pumps will pump at doecreasing capacity down to 860.5" (ippwximat elevation of impeller centerline)'but will have to be. brotiled to minimize cavitation. Additionally, individual SW pump flows h1stthan minimum rated flow of.1000 gpra may catuse excesaeve vibration.
5.1'2 Prior to losing tje SWpump submergeuc-. temportary submersible river water pumpI must be placed in service to maintain E Bay water level. Therefore.
when E Bay level drops to 863' or is forecast io d&up t 863', the temporary submeiriible river water pumps should he. place.d in standby (power connected and pumps nstahied).
