Gentlemen:
The purpose of this letter is to provioe the NRC staff additional information requested in a conference call on August 12,1993, for Carolina Power & Light Company's (CP&L) Brunswick Steam Electric Plant, Units 1 and 2. This information involves the Service Water System license amendment request previously 1;ubmitted to the NRC on December 31,1992, as supplemented by letters dated July 20,1993, and August 9,1993. Enclosure 1 provides the information requested by the NRC staff.
Carolina Power & Light Company is providing,in accordance with 10 CFR 50.91(b), Mr. Dayne H.
Brown of the State of North Carolina with a copy of the proposed license amendment.
Please refer any questions regarding this submittal to Mr. W. Levis at (919) 457-2404.
Very truly yours, S Z

SERVICE WATER SYSTEM RESPONSE TO NRC STAFF INFORMATION REQUEST I
During a conference call between the NRC staff and CP&L, the NRC requested the following information:
How has the Service Water System KYPIPE model been validated?
e Provide analyses to support the conclusions that a single conventional pump is capable of supplying adequate flow to the required components following the first ten minutes of an accident.
The information requested by the NRC staff is presented below. Analyses of various service water system configurations is also included which support the capability of a single conventional service water pump to supply the required componert needs.
CP&L RESPONSE i
The initial validation of the Unit 1 and Unit 2 KYPIPE SW System computer models was i
accomplished by collecting data for seven different system configurations. This data was then compared to results from the model. The configurations tested included one Nuclear Service Water Pump (NSWP) running,2 NSWPs running,2 Diesel Generators (DGs) aligned,4 DGs aligned, RHRSW Booster pumps running and not running, Vital Header aligned, and the Conventional
}
Service Water Header (CSWH) depressurized. The model accuracy was verified by comparing flows and selected pressures for these system configurations to model results.
I Continued accuracy of the SW models is verified by performing a periodic test (PT) aftet each l
refueling outage and comparing actual field data against model results. The PT compares three different configurations rather than the seven used for initial model vaiidation.
1 As stated : Attachment 24 to Calculations G0050A-10 and -12, the Conventional Service Water Header is physically very similar to the Nuclear Service Water Header. Due to this fact, the analysis of the NSWH is considered to be :-presentative of the performance of the CSWH under similar conditions.
r in order to better quantify the performance of a single Conventional Service Water Pump when
[
supplying the RHRSW system, several cases have been modeled and are provided in Attachment 1.
Each of these cases is a post 10 minute cooling case with the following line ups assumed:
RHRSW:
4800 gpm RHRSWP motor coolers l
Vital Header Demand Full Cross Tie leakage from the CSWH to the NSWH El-1 r
b
e Lube water to the SW pumps j
No Dies el Generators One SW Pump rt uning (either 1 A or 2A NSWP which is equivalent to any one of the Conventional Pumps)
,I Two RHRSW Booster Pumps (assumed to be the B and D pumps).
i r
The RHRSW flow is set using the control valve located in line 198. This line is closed and a demand of 4800 gpm is removed from the system at the beginning of the line and reinserted at the end of the line. The 4800 gpm through the RHRSW system will supply more than the required 4500 gpm given the 5% uncertainty reduction. Also assumed is a worst-case condition of 4.5 psi pressure drop across the pump strainers.
The RHRSW pump suction header pressure switches have a trip setpoint range between 13.7 and 17.3 psig. For accident analysis results, a conservative minimum trip setpoint of 18 psig is assumed.
Some of the more important lines and nodes used in the model are listed in Table 1.
