R. C. DeYoung, Assistant Director for Light Water Raactors, PH REVISION No. 2 TO SAFETY EVALUATION REPORT Plant Name: WPPSS Nuclear Project No. 3 and No. 5 Licensing Stage: CP Docket Numbers: STM 50-508; STN 50-509 Responsible Branch: LWR No. 3 Project ? nsger:
A. Bournia Requested Completion Date: January 5, 1976
'Ihe enclosed revised sections of the WPPSS Units 3 and 5 Safety Fvaluation Report (original copy submitted on June 17, 1975 and Revision No. I submitted on September 4, 1975) updates the sections of the Auxiliary and Power Conversion Systems Branch based on new ataendments, up to and including Amendment No. 28.
The following sections are included:
3.4 Water Level (Plood) Design - This section has been revised to incorporate the appliennt's design change of the reactor auxiliary building basement floor.
9.1.3 Spent Puel Pool Cooling and Cleanup System - This Section has been revised to incorporate the applicant's design change. The condensate storage tank replaced the condensate storage pool for makeup water.
9.2.2 Component Cooling Water System - This section has been revised.
In the revision No. 1 to the SER, we stated our concern over the proposed quality group classification of the CCWS piping and lack of system redundancy of ths CCWS supply and return valves for the reactor coolant pump coolit.g. In this SER revision, we have accepted the CCWS design wit.h respect to the RCP cooling based l
on staff acceptance of the Combustion Engineering topical report CI3PD-201, in which it is concluded that a loss of CCW to the RCP will not effect safe. shutdown of the reactor. However, the acceptance of the topical report CENPD-201 is subject to the RCP's satisfactorily passing the test outlined in NUREC 75/112 dated December 1975, " Safety Evaluation Report related to the preliminary desirn of the Standard Reference System CESSAR Systen 80."

9.2.5 Ultimate Heat Sink - This section has been revised to incorporate the recent change of plant arrangement by the applicant. The dry cooling towers will be relocated from the roof of the auxiliary building to ground level, adjacent to the auxiliary building.
9.2.6 Condensate Storage Facilities - This section has been revised to incorporate the recent change of plant arrangement. The condensate storage tanka will be relocated from inside the auxiliary building to outdoors.
9.4.2 Reactor Auxiliary Building ventilation System - This section has been revised to incorporate the applicant's design change. Each ECCS equipment area vill be provided with two fan coil units. The diesel generator rooms will be provided with exhaust fans for roon cooling. We fuel handling building ventilation system isolated dampers will be designed to seismic Category I requirerents.
9.4.6 Component cooling Water System Dry Cooling Tower Electrical Equipment Room Tentilation System - This section is added to incorporate the applicant's design change.
9.5.1 Fire Protection System - This section has been revised to incorporate.
the applicant's design changes in Amendeant 25 and subsequent resolution of resulting concerns. We have reached agreements with the applicant on the acceptability of the subsequent design chances in the fire protection system except for the applicant's proposal to use manual fire hoses and portable extinguishers instead of en automatic CO t tal flooding fire extinguishing system in the 2
Electrical Penotration Areas. We have expressed our concern over this design change and infomed the applicant we will require automatic fire extinguishing capability in the Electrical Penetration Areas. This concern is an open issue. Until resolution of the fire extinguishing system in the Electrical Penetration Area is reached, we conclude that the fire protection system is presently unacceptable.
9.5.4 Diesel Generatof Auxiliary Systems - This section has been revised l
to incorporate the applicant's design change. De diesel fuel oil storage tanks will be relocated from inside the auxiliary l
building to the rooma outside the auxiliary building.
I 10.4.5 circulating Water System - This section has been revised to incorporate the applicant's design change. The turbine building walls will not retain more than l'-R" water above floor for postuisted circulating water system failures.

Except for the Fire Protection System, we find all the proposed snodifications acceptable.
