- 1. PURPOSE.
1.1 The purpose of this procedure is to provide a step-by-step , procedure for the operation of the Borated Water Storage Tank (BWST) in the following modes: Mode Section Filling Operation 4 Normal Operation 5 Heating Operation 6
1.2 System Description
The BWST is located outside the shield and auxiliary buildings. It contains a minimum of 482,778 gallons or 37 feet 4 inches (TS indicated level-(refer to the Tank Curve, Enclosure I) of water 3.1.2.9.b) having a minimum concentration of 1,800 ppa boron at a tempera-ture not less than 35'F. It is used to fill the refueling canal during refueling and to supply the borated water for
- emergency cooling to the containment spray system, low pressure injection system and high pressure injection system. It also supplies makeup water to the spent fuel pool cooling systems.
The tank is provided with an external heating system to protect from freezing in winter. The heating system will be initiated by the operator before the water temperature in the tank has 13 decreased to 50'F. For BWST. temperatures less than 60*F, a minimum of 8 containment vacuum breakers shall be operable. For BWST temperatures greater than or equal to 60*F, a minimum of 6 containment vacuum breakers shall be operable. The design criteria of the containment vacuum breakers with containment 13 spray initiation requires a minimum BWST temperature of 35'F. The BWST water temperature should be maintained greattr than 50*F to ensure a reasonable temperature margin. The heating system is equipped with a pressure switch which shuts down the recirculation pump and closes its suction isolation valve if pump discharge pressure decreases below 20 psig. The heating system should be removed from operation before the BWST water temperature reaches 70*F. The BWST water temperature should not be greater thmo 90*F. A 90'T water temperature was one of the initial conditions assumed in the Containment Pressure Transient Analysis Break Spectrum of the USAR (6.2.1.3.2). The BWST design temperature is 125'F. For control purposes, level iodicators and temperature indicators are installed on the tank which are alarmed in the control room. There are four level transmitters, two low level alarms, a leu low level alarm, a local indicator and four control room level indicators. All four level channels are required for
2 SP 1104.66.7 ~ normal operation. The control room alarms are as follows: BWST LVL LO SFAS CH 1, BWST LVL LO SFAS CH 2, BWST TEMP LO 1534, BWST RECIRC HX OUT TEMP LO, and BWST RECIRC HX FLOW LO. These alarms are located on annunciator Panel 003. BWST LO LO LVL, KFER TO EMER SUMP, is located on annunciator Panel 005. The four level transmitters for SFAS Channels 1, 2, 3, and 4, LT-1515A, B, C, and D respectively, are surrounded by a polyurethane box containing a thermostatically controlled heater to prevent freezing. In addition, all the associated source lines and valves are provided with heat tracing. A sample connection is provided on the 24" outlet pipe connectica for water quality control. The purity of the water can be maintained by circulating,through the spent fuel pool cleanup systes. Addition of makeup borated and demineralized water is available through the use of the borated water storage tank recirculating pump. When filling the BWST up to the desired level, it will be necessary to compute the amount of boric acid (in gallons) and the amount of desineralized water or primary water (in gallons) that needs to be added. Refer to Section 4.2.1 of this - procedure for the formula used for the computation of these amounts.
- 2. PRECAITf!ONS AND LIMITATIONS 2.1 BW3T low level setpoint is 8.0 ft. H O2 (indicated level).
This allows adequate margin for manual switching by the operator (the decay heat removal pump suction to the containment vessel emergency sump) before the BWST empties, thus preventing the possibility of cavitation of the decay heat removal pump. 7 At 4.5 feet, there is approximately 58,195 gallons of usable water available. With maximum safety features operating (approxi-sately 12,800 spa), 4.5 minutes are available for switching operation. The closure time of the valves is approximately one minute. 2.2 Do not add boric acid to the BWST when the reactor coolant system is being borated or deborated as BW 363 (Boric Acid Addition Tanks to Makeup Filter Isolation Valve) is to be left open and would allow unexpected boric acid to enter the makeup tank. 2.3 Whenever the BWST system is inoperable because of failure, repair work in progress, or routine maintenance on the system, the operator is to turn IL 4810, "BWST SYS" ON using HS 4810 on panel C5717. This light is to remain illuminated as long as the system is inoperable.
'A 3 SP 1104.66.12 2.4 BWST hester operation will be required before the temperature
' of the water in the tank reaches 50*F.
12 2.5 DO NOT operate the BWST heater with an outlet water temperature greater than 90*F unless authorized by the Shift Supervisor. 2.6 If the BWST water temperature is approaching 50*F, ensure that the freese protection equipment is energized. The freeze protection equipment is powered from the essential instru-eentation busses Y1 and Y4 as follows: INSTRUMENT AND SFAS FREEZE PROTEC-ASSOCIATED PIPING CHANNEL TION PANEL BUS BREAKER LT-1525A 1 CFP03Q Y1 Y113 LT-15255 2 . CFP04Q Y2 Y220 LT-1525C 3 CFP05Q Y3 Y310 LT-1525D 4 CFP06Q Y4 Y411 2.7 The BWST water temperature should never be greater than 90*F or less than 50*F. The BWST heater should be removed froe . service when the water temperature reaches 70*F. 2.8 If an STAS actuation occurs, the following requirements apply: S 2.8.1 DO NOT OVERRIDE ANY SAFETY EQUIPMENT EXCEPT AS LISTED y BELOW:
- 1. IT PLANT CONDITIONS ARE STABLE AT NORMAL OPERATING OR HOT STANDBY CONDITIONS AFTER A TRANSIENT WITH NO EVIDENCE OF AN RCS LEAE, SYSTEMS MAY BE BYPASSED WITH THE SHIFT SUPERVISOR'S PERMISSION.
- 2. IF THERE ARE ANY QUESTIONABLE CONDITIONS OR ANY SIGN OF AN RCS LEAK, NO SAFETY SYSTEM SHOULD BE BYPASSED WITHOUT APPROVAL OF STATION MANAGEMENT (STATION SUPERINTENDENT OR HIS DESIGNEE).
2.8.2 IF AN SFAS SIGNAL TO SOME EST EQUIPMENT IS " BLOCKED" (I.E. OVERRIDDEN), THAT EQUIPMENT IS INCAPABLE OF RESPONDING TO EITHER ANY SUBSEQUENT AUTOMATIC ACTUATION SIGNAL OR THE SFAS SYSTEM-LEVEL MANUAL ACTUATE (" TRIP")
- PUSHBUTION ON PANEL C5717. BEFORE AN OPERATOR " BLOCKS" ANY SFAS SIGNAL, HE MUST ASSURE THAT THE SAFETY FUNCTION OF THAT EQUIPMENT IS NO LONGER NEEDED.
AFTERWARD THE OPERATOR IS TOTALLY RESPONSIBLE FOR THE PROPER OPERATION OF THAT EQUIPMENT INCLUDING REACTUATION IF REQUIRED, UltrIL THE "BLOCE" IS REMOVED. REACTUATION, SUBSEQLT.NT TO A "BLOCX", CAN BE ACCOMPLISHED TWO WAYS. FIRST, AT THE EQt*IPMENT LEVEL, " BLOCKED" EQUIPME.T V WILL RESPOND TO THE INDIVIDUAL CONTROL e

= 39,429 gallons of water must be added.
4.2.2 Before pumping boric acid from the Boric Acid Addition Tanks (BAAT's), verify'that sufficient boric acid will 9l remain in the BAAT's to meet the requirements of Technical Specifications 3.1.2.8 and 3.1.2.9. 4.2.3 Verify Boric Acid Addition Tanks 1-1 and 1-2 Normal Valve Lineup as per SP 1104.03, R.C. Chemical Addition Operating Procedure. If pumping the concentrates storage tank to the BWST, perform " Valve Lineup List P" of SP 1104.29. NOTE: With plant operating in Modes 1 through 4 9l and BAAT's used as a boron injection flow path, there is no need to verify the BAAT normal lineup prior to pumping boric acid to the BWST. ,3
- o) 4.2.4 Place BWST heater and recirculation pump in service ~
per section 6.1 of this procedure (ensure tank is not empty). - 4.2.5 Open MU 360 (BAAT 1-1 to BWST Recire. Lines). CAUTION: Do NOT add boric acid to BWST while borating or deborating the RCS. 4.2.6 Set MU 23 (Boric Acid Pump (s) Auto Discharge Control Valves) to get a 25 gpa flow rate. NOTE: Flow rate is normally .25 GPM but can be adjusted from 0-60 GPM when desired by adjusting BA Pump Auto Discharge Control Valve MU23 hand controller on control room panel C5702. Return the flow rate to 25 GPM when through. 4.2.7 If using the Boric Acid Pump 1-1 (1-2), start the pump using HIS MU50A (HIS MU50B) located on control room panel C5702 or, if desired, the Boric Acid Concentrates Storage Tank Transfer Pumps 1-1 (1-2) may be used by closing HIS1768 (HIS2817) located on radwaste control panel C17,02. Let the pump run for the length of time computed by the following formula:
~ s crs 7 SP 1104.66.7 T=B, Flow Rate T = Length of time pump is operated (min) B2 = Amount of boric acid being added (gal) Flow Rate = Flow rate of boric acid 4.2.8 Stop Boric Acid Pump 1-1 (1-2) using HIS NU50A (HIS NU503) located on control room panel C5702 or Concen-trates Transfer Pump 1-1 (1-2) using Control Switch HIS1768_(HIS2817) located on the Radwaste Control Panel and close NU23 (Boric Acid Pump (s) Auto Discharge Control Valve) and NU360 (Boric Acid Addition Tank 1-1 to BWST Recire. Line). . NOTE: If pumping from Concentrates Storage Tank, return valves to normal per " Valve Lineup List P" of SP 1104.29. 4.2.9 Add the determined amount of water, B 1 , from Step , 4.2.1 of this procedure by opening DW70 (Demin. Water to the BWST) for desineralized water or open PW35 (Primary Water to BWST) to the desired level. Start a primary water transfer pump or a demineralized water transfer pump, whichever one is needed, if for some ("', reason they are not operating. To add desin. water to the BWST, stop the BWST recire, pump, then close BW-8. Throttle DW70 to obtain desired flow rate. The Flow Rate (spa) x Time (sin) = Total gallons of desin, water. Then close DW70, open BW8, and restart the BWST recirc. pump. 4.2.10 Recirculate the BWST for 48 hours as directed by Section 6.1 of this procedure. 4.2.11 Have Ches & HP personnel run a boron test. The analysis must be greater than or equal to 1800 ppe. 4.2.12 After the BWST has been recirculated for 48 hours, stop recirculation as per Section 6.2 of this procedure. Ensure, however, that the borated water and outside air temperature are both greater than 50*F prior to doing so. Section 4 Completed by Date
- 5. NORMAL OPERATION The purpose of the BWST during normal operation is to provide storage of the contents of the refueling canal and transfer pit for refueling and to provide makeup water for the spent fuel pool. During emergency

5.2 Procedure I 5.2.1 If it is desired to fill the BWST to maintain normal operating level, refer to Section 4 (Filling Operation) of this procedure. .s
, -l~
L 5.2.2 When the BWST water temperature approaches 50*F, refer refer to Section 6 (Heater Operation) of this procedure. 12l 1 - 5.2.3 When the BWST water temperature reaches 70*F perform the following steps.
- 1. Refer to Section 6.2 of this procedure to remove 1' the BWST heater from service.
- 2. Due to stratification, recire. the BWST using either a Decay Heat Removal Pump or Containment Spray Pump. This will mix the BWST sufficiently
;- to provide an accurate overall water tempera-ture. This recirculating can increase the overall BWST water temperature by 10*F or higher.
CAUTION: Even with the large capacity of the BWST, the heat transfer capability of l' the BWST heater is such that the water , temperature can increase from 50*F to - 90*F in just a matter of hours. Also, the outside weather conditions can i change to cause the once balanced conditions in the BWST to inadvertently l r change leading to excessive heating.

9 SP 1104.66.12 5.2.4 If the BWST water temperature goes above 90*F, the
. temperature coald be reduced quicker by using DH system to recire. the BWST per ST 5051.10, "DH/LPI Pump and Check Valve Test".
NOTE: The CCW loop supplying the essential loads should be cut in to the DH cooler. If the loop supplying the non-essential loads were used it could damage the RCP seals since the CCW loop will have to be cooled down in order to reduce the BWST water temperature below 90*F. To reduce the CCW temperature first place the CCW Heat Exchanger Outlet Control Valves (SW1424, SW1434 or SW1429 for CCW Ex 1-1, 1-2 or 1-3 respectively) in manual. Then SW could be cut in as
- needed to cool down CCW so that it approaches the SW temperature.
- 6. HEATER OPERATION .
