1. Pt'RPOSE To provide procedures for operating the Faergency Ventilation System (EVS) in the following modest Mode Section Manual Operation /High Radiation Signals 4 STAS Actuation 5 Abnormal Operation 6 The EVS is normally it, a standby condition, and all the prerequisites of Section 4.1 must be met.

The EVS is designed to provide a negative pressure of 1/4 to 1 1/2 inches W.G. within the annular space between the shield building and the containment vessel, and in the mechanical penetration rooms following a Loss of-Coolant = Accident, (LOCA), and to reduce airborne fission product leakage to the environment by filtration prior to release through the unit vent stack. , The EVS consists of 2 redundant, full capacity fan-filter trains. Each fan is designed for a flow rate of 8000 CD1 capacity, and each filter train has a total particulate efficiency of no less than 957.. The fans are powered from separate 480v Essential Buses, El ( and F1. Each EVS fan takes a suction through separate ductwork from Mechanical Penetration Room 4, passes it through the respective filter train and either into the unit vent stack or back into the mechanical penetration rooms. This recirculated discharge from the fan is returned to the penetration rooms to enhance the mixing of contain-ment vessel leakage, thereby avoiding direct streaming of the radio-isotopes to the filter system and increasing holdup within the annulus. Following a LOCA, an incident level 1 Safety Features Actuation Signal (STAS), (1600 psig Reactor Coolant Systes: Pressure, 4 psis containment vessel pressure, or high radiation level in the contatu-ment vessel), will open the discharge to the unit vent stack dampers and start both KVS fans. (The recirculation dampers are both closed). Ismediately af ter the LOCA, the temperature and pressure within the containment vessel will rise rapidly, causing an increase in the temperature and pressure of the air in the annular space. The EVS begins with 1001, exhaust to the unit vent to lower the pressure in the annular space. As the pressure begins to drop, the recirculation deepers begin to open. allowing partial recirculation of the air to maintain the setpoint negative pressure. This recirculation damper is controlled by a differential pressure controller which controls i s

(otner than a SFAS) within the containment vessel, fuel handlingUpo or radwaste area, the Radiation tionitoring System will stop the , open the motorized dampers which interconnect the affected with the EVS. of the EVS filter units, and starts the EVS fans.The operator then opens the damper of each fan opens by means of electrical interlockThe

This discharge cleanup of the affected systeiss. allows use of the highly efficient filter trains In the event of a Hi Radiation Alarm in the fuel handling area (as sensed by RE8446 & RE8447) both EVS Fans will start automatically EVS Fan 1-1 started by RE8446 & EVS Fan 1-2 will be started by RE8447.

14 2.2 Prior to initiating maintenance on either train, a visual inspection of the redundant train must be performed according to AD 1839.00. 2.3 Whenever the Emergency Ventilation System is inoperable because of failure, repair work in progress or routine maintenance on the system, the operator is to turn IL 4807 "EMER VENT" ON using HS 4807 on panel C5717. This light is to remain illuminated as long as the system is inoperable. 2.4 If a SFAS actuation occurs, the following requirements apply: 2.4.1 DO NOT OVERRIDE ANY SAFETY EQUIPMENT EXCEPT AS LISTED BELOW:

1. IF PLANT CONDITIONS ARE STABLE AT NORMAL OPERATING OR HOT STANDBY CONDITIONS AFTER A TRANSIENT WITH NO EVIDENCE OF AN RCS LEAK, SYSTEM MAY BE BYPASSED WITH TE 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

5. SFAS ACTUATION 5.1 The EVS is normally in a standby condition and is actuated by an incident level 1 SFAS signal. - (SA 111A and SA 112A) ,

The following automatic actions will occur: 5.1.1 EVS fans 1-1 and 1-2 will start. 5.1.2 EVS fan 1-1 discharge damper (CV-5000A) and 1-2 -1 discharge damper (CV-5014A) will open. ., y 5.1.3 Red indicating lights on control room panel C5716 and local red indicating light will be illuminated. indicating the fans have started. I 5.1.4 EVS motor operated cross-connect dampers (CV-5025 and CV-5025) if open, will close (as indicated on C5716) (SFAS incident level 1). 5.1.5 Mechanical penetrations room inlet dampers CV-5017 and CV-5018 will open (as indicated on C5716) when dampers

CV-5024 and CV-5025 leave the fully open position.

5.1.6 The setpoint negative pressure in the annulus ares , (1/4 to 1 1/2 in. W.G.) is maintained by the EVS using' t partial recirculation of the air as needed. The rate of recirculation is regulated by differential pressure controllers (PDC-!.000 and PDC-5014) which position the following dampers.

1. EVS fan 1-1 exhaust control damper, CV-5000A
2. EVS fan 1-1 exhaust recirculation dasper, CV-5000B
3. EVS fan 1-2 exhaust control damper, CV-5014A
4. EVS fan 1-2 exhaust recirculation damper, CV-5014B I

_s 13 SP 1104.15.12 1: 5.2 Operator should verify that the pressure in the annulus area drops to the setpoint negative pressure (1/4 to 1 1/2 in. W.G.) by observing the mechanical penetration room 4 pressure gage (PDI-5000) and mechanical penetration room 3 pressure gage (PDI-5014) on panel C-5716. If pressure does not reach the 12 setpoint, operator should inform the Shift Supervisor. 5.3 To reset after a SFAS actuation, refer to Section 4 of EP 1202.06, Loss of RC and RC Pressure.

6. ABNORMAL OPERATION 6.1 The EVS fans are preceded by a cross tie duct with two normally closed dampers. In the event of a fan failure which causes that fan's charcoal filter bed to heat up to a preset value (200*F),

a temperature switch will open the cross tie duct damper associated with that filter bed (CV-5056 for EVS Fan / Filter Train 1-1; CV-5057 for EVS Fan / Filter Train 1-2), and the operator will get an annunciator alarm (see Table 2). This allows the air from both filter trains to be drawn through one fan. This re-estab-lished air flow will then cool down the filter bed which has heated up. 6.2 If any of the four. filters in the EVS filter unit 1-1 begin to be plugged, the differential pressure across the unit will begin to rise. When this pressure reaches 6" WG as read on P408, the (}[v*,12 

     ,.                 Operator should immediately notify the Shift Supervisor.

l 6.3 If any of the four filters in the EVS filter unit 1-2 begin to be plugged, the differential pressure across the unit will begin to rise. When this pressure reaches 6" WG as read on P409, the 12 Operator should immediately notify the Shift Supervisor. I I l l 1 I L
