The chilled wa ter system is a closed loop that consists of a two 100% capacity centrifugal pumps, which are used to pump water through 100% capacity chiller to any of the air cooling coils in the Control Room ducts.

An expansion tank at the suction of the chilled water pumps and a chemical feed tank are provided along with piping connecting the tanks with the closed loop.

A line from the Demineralized Service Water System provides makeup water to the chilled water loop.

The Nuclear Services River Water System consists of two 100%

capacity Control Building river water booster pumps, which can take suction from either of the redundant Nuclear Services River Water System Headers and supply cooling water to the condenser of either liquid chiller and from there, discharge to the Mechanical Draft Cooling Tower.

The system also includes river water piping that supplies Nuclear Services River Water directly to the air cooling coils of the Mechanical Equipment Room and discharges from there to the Mechanical Draft Cooling Tower.

1.3 Svstem Desicn Recuirements The ventilating system is designed to provide fresh air to the Control Rocm during normal operation.

When outside air temperature is below 70 F, fresh air will he ucmitted-in sufficient quantity to maintain a Control Room temperature o

o of 75 F.

If the outside air temperature is above 70 F, or when the Control Room bypass fans are energized, 1000 CFM of fresh air will be supplied through the minimum outside air duct for replenishment purposes.

On a sig:al from the chlorine gas monitoring System or the Fire Protection System, the air i

supply damper AH-D4092C shuts and no fresh air is supplied to the

{

control Room.

196 321

The system is designed to provide 100% outside air at the option of the operator during normal operation.

The supply fans deliver LATER CFM of fresh air which is sufficient for more than LATER air changes per hour.

Two chiller units are each designed to supply all the required cooling of the Control Room and Cable Room to maintain a 75 F temperature when the ventilation system is in the minimum outside air recirculation mode with an outside air o

air temperature of 92 F.

The units are rated at 110 tons of air condi+-ioning.

Chilled water is circulated through cooling coils in the Control Room (35 tons) and the Cable, Battery and Switchgear Rooms (75 tons).

The heaters are designed to heat the replenishment and recirculation air mixture. to maintain a 75 F temperature in the Cont.rol Room.

The heater coils are rated at 51 IG each and are interlocked with supply fans so that the heaters can-not be energized unless its corresponding fan is operating.

The heaters are designed to maintain the 75 F temperature during the minimum outside air recirculation mode with an outside temperature of 4 F.

The system is designed to minimize the possibility of introducing radioactive contamination, smoke or vapors into the Control Room.

A LOCA or detection of high i.ation in the Control Room supply duct will provide signals which will start one of the Centrol Room bypass supply fans which automatically places minimum outside air recirculation mode.

the system in a

All the air passes through th? Control Room bypass filter unib before it enters the Control Room spaces.

The 1000 CFM of 196 322

~4-

l outside air will cause a slight overpressure in the Contro' Room spaces which will preclude any in leakage from surrounc ing areas.

In the mode, Control Room personnel on eight hour sh.tfts during a 90 day period following a LOCA would not receive an integrated whole body dose in excess of 3 rem from all sources of direct radiation, including exposure during egress and ingress for shift changes.

If an incipient explosion, fire or chlorine gas in detected in the Air Intake Tunnel Auxiliary relays will automatically shut the Control Room air supply shutoff damper,

AH-D4092C, and place the Centrol Room Ventilating System in the 100% recirculation mode.

The detection of combustable vapors in the Air Intake Tunnel i; alarmed on Panels No.

When the exhaust-return air fan is operated, the associated solenoid valve is energized, which allows instrument air to' close the two-position damper in the bypass duct around the exhaust fan. If the exhaust-return air fan motor should fail or be stopped manually, the solenoid valve repositions and allows instrument air to open the damper in the by-pass duct allowing free passage of air to the exhaust-return duct system. After a Control Room supply fan has been started, flow switch AH-FS-5215 or 5219 in the supply fan inlet duct energized flow light AH-FL-5215 or 5219 or verify that air supply flow has been established. A flow alarm on Panel No. 25 will be actuated if a fan is energized and flew is not sufficient. After a supply fan has been, -started, chilled water supply to the Contr and Cable Rooms is established as follows: A chilled water pump, AH-P-1A or 1B, is started from Panel No. 25 using control switch AH-HS-5206 or 5269. Once chilled water flow is established through a water cooler a flow switch will open the river wat er inlet valve, NR-V144A or B, to the associated chiller condenser. A Control Building River Water Booster Pump NR-P-2A or 2B, is started from Panel No. 25 using control switch AE-HS-5267 or 5268. A chiller unit compressor is then started. Interlocks prevent starting a chiller unit unless chilled water flow have been established through the unit and one Control Bnilding River Water Booster pun.p is operating. 196 337 , o-

~: Flow lights AH-FL-5205 & 5282 and AH-FL-5280 & $281 are provided on Pane'. No. 25 to indicate flow into the chilled water pumps and from the control Building River Water booster pumps respectively. All fans, chillers and pumps have local controls in addition to those located on Panel No. 25. Red and green indicating lights are provided with local and remote control switches, When the controls are in the" PULL-TO-LOCK"or"AUTd' positions and the equipment is not running, the green light is energized and when.the equipment is operating the red light is energized. 3.2 Normal Coeraticn, The thermostat (AH-TS-5 209) in the Control Room maintains the set temperature as follows: As the room temperature drops o below the set point (75 F), the operating fan-coil unit electrical heating elements are energized in multiple stages. The heating elemc s in the idle fanm oil unit are not energized due to an electrical interlock with the fan motor. As the room temperature rises the heaters are de-energized and when the temperature is above the set point, the thermostat positions the outside, re-turn and exhaust dampers AH-D4092D, AH-4092E and AH-D4098 so as to increase the proportion of outside air handled by the fan, and decrease the proportion of recirculated air. If the room temperature continues to rise and the dampars are positioned for 100% outside air, the thermostat modulates the three-way valve (AH-V33A or 33B) ' located at the outlet'of the cooling coils ~ to admit ch111ed water to the cooling coils chiller. 196 338

l Control of the outside, return and exhaust dampers is re-moved from the Control Room thermostat whenever the outside air temperature is above 70 F. This is accomplished by the temperature indicating controller AH-TIC-5209, with its sensing element located in the outside air duct. The controller positions the damper for minimu outside are recirculation. In this mode, all of the cooling a supplied by the chiller units. The rolled media of inlet filters AH-F-2A & B are advanced automatically by a differential pressure switch when pressure drop across the filter reaches a predetermined value. The exhaust fans serving the kitchen (AH-E-25) and toilet (AH-E-5 ) areas and their associated dampurs are electrically N interlocked with the light switches for these areas so that they will operate whenever the lights are turned on. Annunciators are provided per Table 4 to annuciate deviations from normal operating conditions on Panel No. 25 in the control Room. 3.3 Soecial and Infrecuent Coeration Control switch AH-RS-5207 allows tne operator to test the exhaust fan AH-E-35 without starting either supply fan in fan-coil unit AH-C-16A or B. The switch also allows the operator to stop the exhaust fan by placing the switch in the " PULL-TO-LOCK" position without de--energizing supply fans. To remove smoke-and vapors from the Control Room, the toggle switch in the local fire detection panel must be placed to {I 196 339 M

1 " DISCONNECT". This overrides al ,e interlocks cssociated with the local fire fatection panel and allows the dampers to be positioned for 100% outside air and the supply fans to be starte'd. The override switch may be returned to normal when the smoke and vapors have been reduced sufficiently to reset the detectors. Provision is made to allow the system to being in all outside air, with no recirculation air, regardless of the outside air temperature. This is accomplished by a Manual Sw..cch (AH-KHS-5 209 ) on Panel No. 25 in-the Control Room which actuates an electric / pneumatic rela.y in the control ine to the outside, return and exhaust dampers. When this is activated, the cooling coils may not have sufficient cooling capacity to maintain Control Room temperature at 75 F. This mode would be used to clear the Control Room of smoke and vapors after a fire. 3.4 Shutdown The chiller units shoulm be shutdown first; however, ensure tha t they are not required for cooling the Cable Room. The chiller units and the liquid cooler pump can hutdown locally or re-motely from 'anel No. 25. Before stopping the supply fans or the bypass supply fans, if they are running, the control switch for the standby fans must be placed in "P ULL-T O-L OCK ". The running bypass supply fan is de-energized and ten (10) seconds later the control switch on the standby fan may be placed in "A UTO ". The control switch for the supply fans must be placed in " PULL-TO-LOCK" to prevant restarting af ter it has been stopped. The exhaust fan will stop automatically when both supply fans are de-energized. f 196 340 O _22_

) ? 3.5 Emercency A signal from the Safety Features Actuation System, Radiation Monitoring System or Chlorine Gas Monitoring System automatically starts one Control Room bypass supply fan which are interlocked with AH-V 124A & B and AH-V125A & B to position dampers AH-D4092A, B, D and AH-ED4098 for recirculation. A signal from the chlorine Gas Monitoring System also closes damper AH-D4092C which places the ventilation system in the 100% recirculation mode. The SFAS system also starts Control Building RW Bocater punps, a chilled water pump and a liquid chiller uvit. After detection of an incipient explosion, fir"cor chlorine gas in the Air Intake Tunnel, the system is shifted to 100% recir-culation, by shutting the air supply shutoff damper, AH-D4092C. Cperation of a Control Room bypass fan energizes its associated solenoid valve which allows instrument air to open the two-position damper in the fan discharge duct. A differential press-ure controller (AH-DPIC-5211), controls the inlet vane dampers to allow constant flow as the filters become loaded. A differen-tail pressure switch ( AH-dPS-5 212) actuates an alarm in the Control Room dhen the filters be5 cme ~ loaded with

dust, as indicated by an increased pressure drop across the filters.

A signal from the local fire detection panel stops all the fans and itions the dampers AH-D-4092A, B, C and AH-ED-40 3 2 for. recirculation when fires or smoke is detected in the contro l Room. ? 196 341 O

t 4.0 .1AZARDS AND PRECAUTIONS Care must be taken w start a liqu'd cooler pump before starting a Control Building river water booster pump and stopping these booster pumps if there is no demand for river water to prevent them from running at a shutoff head for long periods of time. The filters in the control Rocm bypass filter train must be treated as potentially contaminated. Care must be taken when changing these filters especially after a LCCA or high radiation emergency. Combustable vapors in the Air Intake Tunnel alarm on Panels No. 1 but no automatic action is provided. 196 342 e _RA
