the initial phase of shutdown cooling, before the intiation oC RHR cooliny. In either case, the steam pipinq to the ISSS equip- mcnt an? the equipment itself is in a warmed up anddrained condition. Stcam generator secondary side pressure exists up to the ISSS stop valve and steam dump valves. Orificed bypass flows maintain the operating cylinders of these valves hot. Similarly, a small bypass flow around the ISSS stop valve keeps the down- strea,m piping hot. A pc~rtjon of this steam flow is also used to maintain the temperature of the bnrated water storage tank (if requirca). Condensate whi,.'- is formed from the w,3rm up steam collects in the condens~tc dr~in t~1.1,. From hcrc it is purn?.-, hack to the main con dens at.^ and fcedwatl?r system. Floor drainaqe is collected in a flour dr~ln ?jump from which it is pumped to thc liquid radwaste systom. The wstcr lcvcls in t.hc condensate drain tanks and floor drain sumps are intentionally maintained low whcn the ISS system is in the :;tanclt)y mc:dr: so that sufEicient volume is a'jailablc to collect the anticipated drSlinaqca dur inq ISSS operat ion. This is because n pumps and floor drain pumps do not operate on. hu:; (480 V AC) i: r i d in each ISSS bunker.
standby mode. For example, the bus for ISSS train A would be energized from thc A bus of the class IE 4KV pouer distribution '. syst.em. Thc ISSS 480 V bus su~pl'ies power to the ISSS battery charger, maintaining the ISSS batteries fully charged, and also to thc condcneate drain pumps and floor d:ain sump pumps. The power supplies to the ISSS 400 V busscs are tripped when the ISS is actuated. Lighting loads and valvc solenoids are supplied from thc ISSS battery. Actuation of thc ISSS system is manual from either the main control room or at a Ioc~l station in the ISSS bunkers. Manual actuation has been selcctcd since it 1s intended that the ISSS only operate in response to a sabotagc or other gross emergency. It is believed that plant opcratorc can best make the judgement that such an emerqcncy docs or does not exist. Relyinq on the sensing of plant parameters such as voltage or flow to actuate the system automatically is bol icved to bc undesirable since conditions : othcr th~n snbotagc could cause actuation. The actuation logic i , could bccome quite complex if it had to determine, from sevcral paramctcrs, that a sabotage evcnt was in progrcso. Elimination of plant paramctc!r sensing for aut.omatic actuation also reduccs the numhcr of intcrlacc!s hctwcen :b,c ISSS arid the rcmaindcr of the? plant an(i tb,cir .2:;:;aci~t1?d ::~bot;lqc vu1ncr;lCil icier,. Sufficient i time (on the ord~?r oS one hour) is avail;lt?!e to 3s:iez.s thc need , . . for thr LSSS and to actuatc it manually.
