4.5.2 R, et*r Building c cling Syntems Applicability Applies to testing of the reactor building emergency cooling systems.

Objective, To verify that the reactor building emergency cooling systems are operable.

Specification 4.5.2.1 System Testa 4.5.2.1.1 Reactor Building Spray System (a) once every 18 months, a system test shall be conducted.to demonstrate proper operation of the system. A test signal will be applied to demonstrate actuation of the reactor building spray system (except for reactor building inlet

)

valves to prevent water entering nozzles).

(b) Station compressed air or smoke will be introduced into the spray headers to verify the availability of the headers and spray nozzles at least every five years.

(c) The test will be considered satisfactory if visual observation and control board indication verifies that all components have responded to the actuation signal properly.

Tho v rificaticn of carvica watsr flow reto to scch trein of rccctor building I

emerg:ncy c:oling io p:rformed to encuro that cufficient pect-cccid:nt rccctor building heat load can be removed by the coolers. The flowrate specified in the surveillance requirement corresponds to the conservative configuration of two fans and their associated cooling coils for each train of reactor building emergency cooling. The minimum flow rate which corresponds to the post-accident heat removal capability for other system configurations may be justified consistent with the bases of Specification 3.3.4 (a).

Addition of a biocide to service water is performed during reactor building emergency cooler surveillance to prevent buildup of Asian clams in the coolers when service water is pumped through the cooling coils.

This is performed when service water temperature is between 60F and 80F since in this water temperature range Asian clams can spawn and produce larva which could pass through service water system strainers.

The delivery capability of one reactor building spray pump at a time can j

be tested by opening the valve in the line from the borated water storage 1

tank, opening the corresponding valve in the test line, and starting the I

corresponding pump.

Pump discharge pressure and flow indication l

demonstrate performance.

With the pumps shut down and the borated water storage tank outlet closed, the reactor building spray injection valves can each be opened and closed by operator action. With the reactor building spray inlet valves closed, Jow pressure air or smoke can be blown through the test connections of the j

l reactor building spray nozzles to demonstrate that the flow paths are i

open.

The equipment, piping, valves, and instrumentation of the reactor building i

emergency cooling system are arranged so that they can be visually inspected. The cooling fans and coils and associated piping are located outside the secondary concrete shield.

Personnel can enter the reactor building during power operations to inspect and maintain this equipment.

l The service water piping and valves outside the reactor building are inspectable at all times, operational tests and inspections will be performeo prior to initial startup.

Two service water pumps are normally operating. At least once per month operation of one pump is shifted to the third pump, so testing will be l

unnecessary.

As the reactor building fans are normally operating, starting for testing is unnecessary for those verified to be operating.

l Amendment No. 34,43,M 3,444 95

The verification of service water flow rate to each train of reactor buildina emeroency coolina is performed to ensure that sufficient post-accident reactor buildina heat load can be removed by the coolers. The flowrate specified in the surveillance recuirement corresponds to the conservative confiauration of two fans and_their associated coolina coils for each train of reactor buildina emeroencv_coolina. The minimum flow rate which corresponds to the post-accident heat removal capability for other system conficurations may be iustified consistent with the bases of Specification 3.3.4 (a).

Addition of a biocide to service water is performed during reactor building emergency cooler surveillance to prevent buildup of Asian clams in the coolers when service water is pumped through the cooling coils.

This is performed when service water temperature is between 60F and 80F since in this water temperature range Asian clams can spawn and produce larva which could pass through service water system strainers.

The delivery capability of one reactor building spray pump at a time can be tested by opening the valve in the line from the borated water storage tank, opening the corresponding valve in the test line, and starting the corresponding pump.

Pump discharge pressure and flow indication demonstrate performance.

With the pumps shut down and the borated water storage tank outlet closed, the reactor building spray injection valves can each be opened and closed by operator action. With the reactor building spray inlet valves closed, low pressure air or smoke can be blown through the test connections of the reactor building spray nozzles to demonstrate that the flow paths are open.

The equipment, piping, valves, and instrumentation of the reactor building emorgency cooling system are arranged so that they can be visually inspected. The cooling fans and coils and associated piping are located outside the secondary concrete shield.

Personnel can enter the reactor building during power ooerations to inspect and maintain this equipment.

The service water piping and valves outside the reactor building are inspectable at all times.

Operational tests and inspections will be performed prior to initial startup.

Two service water pumps are normally operating. At least once per month operation of one pump is shifted to the third pump, so testing will be unnecessary.

As the reactor building fans are normally operating, starting for testing is unnecessary for those verified to be operating.

Purpose:

The purpose of this calculation is to provide the basis for the minimum SW flow to each train of reactor building service water cooling coils under a nonr d system configuration in support of a May,1995 proposed amendment to Technical Specification 4.5.2:

Methodology:.

a) Part A will determine the thermal performance of parallel RB coolers and associated fans for flow rates assuming a 50/50 flow split between the coolers. The resulting table will be used to document train operability at 95 'F inlet SW temperature.

b) Part B provides a sensitivity study using a conservative result from Part A for flow imbalances other than 50/50 between the two coolers.

9. Ops Proc. 1104.033, rev. 52, pc-1 & pc-2 Assumptions and Given Conditions

1. Cooler design air flow is 30,000 cfm. Cooler air flow rate is conservatively taken as 27,378 acfm based upon the latest air test for "C" unit (ref. 4) which tested at the lower flow rate on the airside of the four RB coolers. This is a conservative assumption since the data was taken with flow through the normal inlet ductwork and the bypass damper closed. During accident conditions, the bypass damper will open, eliminating the inlet ductwork friction lou. Previous testing with the damper open resulted in air flows in excess of 30,000 cfm for all four eqolers (ref. 5). This assumption provides some design margin.

2. Holtec AIRCOOL will be used to model thermal performatice, with corrections to match AAF performance data, as described below.

3. The AAF design fouling factor of 0.002 is used (ref.1).

4. The required heat transfer is taken as 105% of 53.7 million btu /hr. This represents a 5% margin above the heat removal rate assumed in the design basis accident (the l By: Bold l Chk'd:

Calculatisn 95-E-0046-03, rev. O Page 2 cf 5 COPATTA analysis, ref. 2). Entering air is input at 286 *F,74 psia and 100% relative j

humidity (ref. 2).

S. Thermal performance of VCC-2A,2B, and 2D is the same as VCC-2C.

Part A:

The COPATTA analysis (ref. 2) is based upon heat transfer input from ref.1, which in turn is based upon performance data generated using American Air Filter (AAF) computer programs. Because of certain differences in modeling, the Holtec AIRCOOL program slightly over predicts cooler performance. To benchmark Holtec results against AAF results, benchmark cases were run (ref. 3) to determine correction factors for other AIRCOOL generated performance data.

American Air Filter determined performance data for two cases ofinterest, SW flow at 600 and 1200 gpm with inlet SW temperature of 95 *F (ref.1). Heat transfer rates for both of these cases were determined. Using the same input data, the Holtec program AIRCOOL was used to determine predicted heat transfer rates, which were expected to be higher. Results at these two conditions were used to determine corrections factors, which will be used to correct the predicted Holtec results to AAF results (ref. 3).

Three Holtec analyses are run using 95 F SW inlet temperature and flow rates that result in heat removal rates equal to or greater than 56.5 million b'.u/hr.

Part A Calculation:

The AAF input data are as follows (ref.1):

Using 800 gpm in Part B is therefore conservative and provides margin to be applied for the flow split analysis.

Part B:

Part A determined that 800 gpm at 95 *F inlet SW temperature exceeds a conservative heat removal of 56.5 million btu /hr. Part B will split the flow between the parallel RB coolers in 10% increments to determine heat removal capability at other than a 50/50 flow split.

Calculation 95-E-0046-03, rev. O Page 5 of 5 Part B shows that 105% of design accident heat removal is met with a flow imbalance

!between the coolers where greater than 70% of the total flow is through one cooler and less than 30% total flow is through the parallel cooler.

The coolers are the same size, at the same elevation and were designed for a 50/50 flow split. Attachment 2 demonstrates that this is the case. shows that the limits for the operability of the RB coolers will be reached well before a 70/30 flow split is reached. The curves in the attachment are based on the 2

2 formula AP = K' Q or the resistance factor, K, equals AP/Q.

Baseline and acceptance resistance factors Ka and K4were determined from flow data taken during the last refueling outage (IR12) (ref. 9) when the service water system was in its Engineered Safeguards line-up Ka represents the baseline actual system resistance through parallel RB coolers and piping. K4 represents the operability limit resistance factor for two parallel coolers. The third resistance factor, Kr, was determined from recent testing with flow through one cooler completely blocked by a blind flange (ref. 6).

From examination of the three resistance curves, the large difference between the one and two cooler baseline curves indicates that the assumption of a 50/50 flow split is valid.

Conclusion A calculated flow rate of 800 gpm provides ample margin for design accident heat removal and includes allowance for flow imbalances between the parallel coolers that far exceed expected flow imbalances.
