STARTUP FEEDWA'IER SYSTEM FWS, WATER HAMMER) Westinghouse should address the issue of plant damage due to water hammer during startup.
Response: DSER OI 10.4.9 2 Information contained in SSAR, section 10.4, Revision 6, and in SSAR Appendix 3B, Revision 7, addresses the potential for water hammer in feedwater lines. The " Main Feedwater Line" portion of SSAR subsection 3B.2.3 addresses a number of design features included in the main and startup feedwater system, piping, components and control that minimize the potential for water hammer. De potential for water hammer during startup is minimized by having a startup feedwater system separate from the main feedwater system. His startup system can not add cold water to the hot main feedwater system, is sized appropriately for startup, has control valves and other features designed for stanup service, is routed to minimize geometric sources of water harnmer, and feeds a steam generator nozzle and feed spmy system separate from the main feed ring. His item is closed.

i PREllMINARY NRC REQUEST FOR ADDmONAl. INFORMATION Question 410.287 Section 9.2.10 3 of the SSAR (Revision 3) states that the hot water heating system (VYS) is a high energy system and has no safety-related function. Provide information regarding the system pressure and ternperature and v:rify that any failure of the VYS piping er equipment will not directly or indirectly result in lose of required redundancy in any pomon of the systems or equipment in the safety-related areas. Also, explain why the system was changed
@. to a high-enere,y system from a moderate-energy system.
Response
SSAR subsecoon 9.2.10.3, Revision 6, provides the basis for hot water system not requiring a nuclear safety h evaluation. The subsection also provides a description of the design response to the fact that the hot water heating system is a high energy system. The specification change from moderate-energy to high<nergy was as a result of a natural design progression. The system design parameters were respecified to ensure its ability to proside hot water under all design conditions.

Question 410.284 Section 9.2.7.2.1 of the SSAR (Revision 3) states that the high capacity subsystem consists of two chilled water pumps, two water-cooled chillers, a chemical feed tank, and an exparsion tank. An air separator was climinated hom the previous SSAR revision. However, each of the two loops of the low c2pacity subsystem still contains of an air separator and other components that are similar to the high capacity subsystem. Explain why the air separator is not required in the high capacity subsystem.
Response
SSAR subsection 9.2.7.2.1, Revision 6, Properly describe the low capacity subsystem without an air separator. Air separators are not required since the expansion tank is sized and located to serve this function.

i I This LCO ensures that the startup feedwater isolation and LCO control valves will actuate on command, following a SLB or i
FLB, and isolate startup feedwater flow to the steam l
generators.
l The startup feedwater isolation and control valves are l coM1dered OPERABLE when they closa an an isolation actuation signal, and their isolation times are within the required limits.
l APPLICADILITY The star +'t feadwater isolation and control valves must be OPERABLE whenever there Is signitidHT EHE and ungtyf lu i
' the Reactor Coolant System and the steam generators, This ensures that, in the event of a high energy line break, a single failure will not result in the blowdown of more than one steam generator.

When the valves are closed, they are already performing their safety function.
In N0DE5 4, S, and 6, the energy in the steam generators are low, and isolation of the startup feedwater system is not required.
