HEATING & VENTILATION SYSTEM AUXILIARY BUILDING
1.0 INTRODUCTION
1.1 System Functions The functions of the Auxilialy Building Heating and Ventilating System are:
a.
To provide fresh, filtered, tempered ventilating air to all spaces within the Auxiliary Building in sufficient quantity to produce and maintain room temperatures suit-able for the operating personnel and the mechanical and electrical equipment.
b.
To provide air ficws within the building frcm clean areas toward potentially contaminated areas and to exhaust from the latter, so as to minimize the chance of spr ead-ing contazaination.
c.
To treat the exhaust air by filtration, as necessary, so that discharges from the plant vent will be less than MPC (maximum permissible concentration) requirements of 10CFR20.
d.
To maintain an average pressure within the Auxiliary Building slightly lower than atmospheric, so as to reduce the likelihood of spreading radioactive contami-nation to the atmosphere.
1.2 Summarv Descriaticn of Svstem (Reter to B&R Dwu. No. 2042, R ev. 7)
The system is a push-pull heating and ventilating system consisting c.. a supply air system and an exhaust air system, I
which provides once-through ventilation with no recirculation.
The supply air system consists of two 50% capacity centrifugal fans together with prefilters, final filters, electric preheat
~;
coils and necessary sheet metal ducts arranged to take out-side air from the Air Intake Tunnel and deliver it to the
~
~
various spaces within the Auxiliary Building in proportion to the ventilation requirements.
Electric reheat coils are provided in the branch ducts supplying air to the various floor levels, to aive individual zone control.
The Exhaust Air System consists of four 50% capacity centri-fugal fans, two 50% capacity filter trains, and the necessary sheet metal ducts arranged to exhaust air from the ventilated spaces in such a manner that air flow within the building is from. clean areas toward potentially contaminated areas.
The exhaust air is discharged to the station vent.
Each filter train consists of a prefilter, a high effic'- my particulate air (HEIA) filter, a charcoal filter and a n ad HEPA filter.
(
To prolung the life of the filter trains, ex2,2_t air is bv_-
passed around the filters whenever monitoring instruments do not indicate radioactivity in the exhaust air stream.
1.3 System Desicn Recuirements The Ventilating System is designed to provide fresh air to maintain temperature below 104 F in areas where personnel and electrical equipment are located and below 120 F in other spaces.
The supply fans are designed to provide approximately 84,000 CFM of fresh air from the Air Intake Tunnel which is sufficient for three air changes per hour.
Three air changes are sufficient to remove heat from people, lights and equip-3 ment and maintain the above temperature 1bmits with an out-side air temperature of 98 F.
196 285
e The system is designed to minimize the spread of radio-
' active contamination by distributing air so that it flows from lesser potentially contaminated spaces to more poten-tially contaminated spaces.
No recirculation is permitted.
The Exhaust System contains a filter bank which is normally bypassed, but is used to remove contaminated particles in an emergency.
Additionally the Auxiliary Building is main-tained at a slight vacuum so that any leakage is into the building rather than out.
The vacuum is maintained by a differential pressure indicating controller which controls the inlet vanes on the Auxiliary Building exhaust fans.
The system is designed to heat the supply air so that a minimum indoor temperature of 70 F is maintained.
A pre-heater upstream of the supply fans and electric heaters in the supply ducts to the various spaces maintains this tem-perature.
Ductwork and equipment components that could contain radio-active material are designed to withstand forces due to a Class I seismic occurrence.
All other ducting and equip-ment are Class II seismic.
The design cleanliness rating is Class D.

An interlock prevents the heaters frem being energized unless both supply fans are running.
The heaters are controlled by thermostats located on the corresponding elevations of the Auxiliary Building.
Each heater is provided with local OFF-AUTO switches with local indicating lights and a manual snap action thermal cut-out which trips the MCC breaker in the event the heating element overheats; the breaker must be reset manually.
All the heaters receive power from 480V Bus 2-45.
2.1.7 Auxiliary Buildinc Exhaust Filter Units The Auxiliary Building Exhaust Filters (see 2.1.7.1 through 2.1.7.3) are two, 50% capacity (42,000 CFM) ; parallel filter trains located at Elev. 328.0' in the Auxiliary Building.
Each filter train consists of the following component filters:
2.1.7.1 Roll-Aire Filters, AH-F-8A and 8B
}
s The Roll-Aire Filters (see Table 6) are located at the upstream end of ea :h filter train.
The filter is construct-ed of 2" thick fiber glass reinforc< d by steel wires and is 196 29i
~
i automatically progressed to maintain a uniform pressure across the filter.
The Roll-Aire Filters have a 1/6 HP motor with local controls and indicating lights and are powered from 120v power panel MP2-35.
2.1.7.2 HEPA Filters, AH-F-9A & 9B and AH-F-30A & 30B The high efficiency particulate air filters (see Table 7) are the second and fourth filters in each filter train.
The HEPA Filters are constructed of a dry, fibrous, high interception,_ _ _ _ _ _sub-micron glass fiber which has an efficiency _ _ _ _ _
of 99.97% for particles larger than.3 microns.
The press-ure drop across a clean filter at rated capacity is 1.2 inches (H[).
2.1.7.3 Activated Carbon Filters, AH-F-LOA & LOB
(
The Activated Carbon Filters (see Table 8) are located between the ESPA Filters in each filter train.
The carbon filters are constructed of impregnated activated charcoal and are water repellant and fire resistant.
The carbon filters are cesigned to trap and remove gaseous contami-nants from the air stream.
Sprinkler systems are pro-vided for spraying cells at a minimum flow rate of 1.5 gpm on the air entering side of the bank for fire protection.
2.1.8 Elevator Machinerv Room Ventilation Fan, AH-E-41 The Elevator Machinery Room Ventilation Fan (see Table 9) 2 is located in the Elevator Machinery Room, Elev. 347.O'.
}
It is a single stage, centrifugal fan rated at 1400 CFM.
The fan takes filtered air from the 328.0' elevation of the Auxiliary Building, circulates the air through the
}hb 292
~ -
.~
Elevator Machinery Room and returns the air to the Auxiliary Building when room temperature exceeds 90 F.
The fan is driven by a 3/8 HP motor which receives power from 120v power panel MP2-46.
A local CN-OFF-AUTO switch is provided.
2.2 Instruments, Controls, Alarms and Protective Devices The followi, devices are used for nu Auxiliary Building Heating and Ventilating System instrumentation. (See Table 10).
Control switches with pilot lights to indicate operation, are furnished on HVAC Contrcl Panel No. 25 in the Control Room, for r$ mote operation of the fou; 50% capacity ex-haust fans which are operated in pairs to provide 100%
of design capacity.
Electrical interlocks automatically start the two supply air frns when any pair of exhaust fans is operated.
Pilot lights on Panel No. 25 indicate opera-tion of the supply fans. Control switches are also furnish-ed on Panel No. 25 for manually testing the operation of the supply fans.
A solenoid valve is energized and allows instrument air to open the automatic damper located in the discharge air stream of each supply and exhaust fan when the associated fan motor'is energized.
The quick closing damper in the outside supply air duct it made operable through a pneumatic relay when either of the
___ supply fan motors is energized,__
and is positioned by a differential pressure indicating controller to produce 2
a uriform pressure drop across the filters, heating coil and damper.
The purpose is to provide a constant quantity of outside air, regardless of the buildup of filter resist-ance, up to the limit where filters should be changed.
An 196 293
alarm at the annunciator on Panel No. 25 will be energized through a pressure switch when the damper is no longer able to maintain the set differential pr essure, i.e. when the damper is fully open.
A differential pressure indicating controller maintains a 1/16" H O vacuum in the Auxiliary Building by controll-2 ing the inlet vanes on the exhaust fans.
The differential pressure indicating controller, AH-DPIC-5304A, compares the pressure in the supply duct from the Air Intake Tunnel and the 305.0' level of the Auxiliary Building.
The diff-erential pressure is indicated locally and in the Control Rcom on Panel No. 25 and an alarm is actuated also on Panel No. 25 when the vacuum is less than 1/32 " H 0.
2 The roll type prefilters in the Supply Air System and in the two filter trains of the Exhaust Air System are progressed c
automatically by local motors actuated by differential pressure switches.
When the filters have reached the end of their travel an alarm is annunciated at Panel No. 25 in the Control Room.
Flow measuring and indicating devices are orovided to indi-cate the air flow rate in the main supply and main exhaust ducts.
Flow rates are indicated on Control Panel 25 as well as locally in the Auxiliary Building.
?
Control of the preheat coil in the supply air duct consists j
of a temperature indicating controller which senses the temperature of the incoming air and positicns a locally mounted step controller which energizes the various stages 196 294
~-
of thc electric preheat coil.
Setting of the temperature controller is such that the first stage of heating is ener-gized at 50 F incoming air and all stages are energized at 0 F.
Reheat coils at the three floor levels (328'-0",
305'-0", and 280 '-6 ")
are controlled by local thermostats through pneumatic step controllers.
Indication of ambient temperatures at four floor levels (328'-0",
305'-0",
280'-6" and 258'-6") is given through the multipoint temperature recorder on Control Panel 25.
Flow of air normally bypasses th e exhaust filters.
If radio-active contamination reaches a predetermined level a radia-tion monitoring device, HP-R-222, located in the exhaust duct upstream of the exhaust filters, closes the bypass damper, opens the exhaust filter isolation damper, and annunciates an alarm on Panel 25.
If the radioactive con-tamination level continues to rise a radiation monitoring device, HP-R-228, located downstream of the exhaust filters, shuts down the supply fans which will significantly increase the vacuum in the Auxiliary Building.
If the contamination level continues tc increase a radiation monitor located in the station vent, HP-R-219, de-energizes the exhaust fans and annunciates another alarm on Panel No. 25.
Refer to System Description No. 52 for Radiation Monitor Set Points.
When the contamination has been reduced to acceptable levels the ventilation fans must be restarted manually.
The dampers must be repos 2.tioned manually by depressing th Filter Bypass damper pushbutton on Panel No. 25.
The pushbutton also has
-l a test position which will position the dampers for air ficw through the filters.
(
196 295 -
1 3.0 PRINCIPAL MCDES OF OPERATION 3.1 Startuo The Auxiliary Building is started up as follows:
One pair, either AH-E-8A & B or AH-E-8C & 8D, of exhaust fans is started manually.
Auxiliary contacts in the ex-haust fan control circuit open the corresponding exhaust fan discharge damper and start the pair of Auxiliary Build-ing supp.1.y fans.
Auxiliary contacts in the supply fans open the. corresponding supply fan discharge damper and the system inlet damper.
3.2 Normal Oneration In normal operation, both supply fans and two of the four exhaust fans are operating.
The charcoal and HEPA filters in the exhaust system are in the by-pass position as long as the radiation level in the exhaust air is below the setting of the monitoring instruments.
Winter tempering and heating is controlled autcmatically to provide a mini-mum 70 F average space temperature.
Two differential-pressure-indicating controllers are employed; AH-dPIC-5312 has its probes cannected across the filter-inlet damper ccmbination.
The contrciler is set to maintain a constant pressure drop across the filter-damper assembly.
The dampers, therefore, throttle the flow when the filters cre clean, gradually opening as tley become f
fouled.
The purpose is to provide a constant quantity of outside air, regardless of the buildup of filter resistance.
An alarm at the annunciator on Panel No. 25 will be ener-gized through a pressure switch when the differential f96 pg
~:
~
pressure exceeds 125% of the differential pressure con-troller setting, indicating the need to change filters.
AH-dPIC-5304A has its probes conrected between a point in the Air Intake Tunnel and a location near the ceiling of Elevation 305'-0".
The desired differential of.063" W.G.
negative (tunnel minus building) is maintained through control of the inlet vane dampers poc it.on in the exhaust blower inlet ports.
An alarm on Panel 25 will be energized through a pressure switch when the differential pressure decreases to 1/32" W.G.
negative.
Heatina is accomolished in two chases:
a.
Incoming air is pre-heated by passing it through electric resistance elements ( A H-C-9A thru AH-C-9J),
energized in 142 KN steps, starting at 50 F with the last step powered at o F.
The controller senses out-side air temperature.
b.
Heating of each of the air streams delivered to the three floor levels is controlled by local thermostats through pneumatic step controllers which energize the electric heaters AH-C-42A through C, Elev. 305',
AH-C-41A & B, Elev. 286.5', and AH-C-10A through lOF, Elev. 328.0' in appropriate increments to maintain the minimum 70 F temperature.
Air Sucolv rate and the exhaust rate are read from flow i
i indicators located both locally and in the Control Room.
~;
Pito". tubes in the air stream deliver a differential press-ure to a flow transmitter which transfers the 0-3 " W.G.
s b }),7
signal to an outlet pressure of 3-15 psi.
This is then fed to the flow indicators.
A thermostat located in the Elevator Machinery Room energizes a ventilating fan when the room temperature exceeds 90 F.
The fan cools the Elevator Machinery Room by circulating air from the 328.0' elevation of the Auxiliary Building through the room.
3.3 Shutdown The Auxiliary Building ventilation System is shutdown by stopping the exhaust fans.
The idle pair of exhaust fans must have their control switches in PULL-TO-LOCK to over-ride the automatic backup interlock.
The supply fans will automatically stop immediately after the first exhaust fan is de-energized.
The system inlet damper and the
(
fan discharge dampers will shut automatically.
The Eleva-tor Machinery Room fan control switch must be placed in OFF.
Shutdown of the Auxiliary Building Ventilation System should be minimized.
Plant shutdown will not allow secur-ing of equipment located in the Auxiliary Building which requires ventilation.
Also, shutdown of the Ventilation System will break the vacuum in the Auxiliary Building and elbminate the flow of air from clean areas to poten-tially contaminated areas.
2 2
b 298
~.
3.4 Saecial or Infrecuent ooeration A fire protection signal shuts down the Auxiliary Build-ing Ventilating System.
Smoke and fumes must be removed by placing the exhaust fan override switch on the Fire Protection Panel No. 7 to OVERRIDE and energizing the exhaust fans.
When the smoke or fumes have been reduced suff.ciently to reset the Fire Protection System, the Auxf.liary Building Ventilation System should immediately be placed in normal operation to complete evacuation of the building.
3.5 Emercency Should an incident or accident occur that causes the re-lease of radioactive particles and gases into the Auxiliary Building the radiation monitoring devices will function to limit the spread of the contamination by performing as described in section 2.2.
When the source of radioactivity has been contained and the contamination removed the opera-tor, upon notifica tion from the proper authority, will manually restart the ventilation system.
A signal from the Fire Protection System de-energizes the exhaust, supply and Elevator Machine Room fans.
De-energizing the exhaust fans closes their corresponding discharge dampers.
De-energizing the supply fans closes their corresponding discharge dampers and also closes the system inlet damper.
The system must be restarted manually 5
after the emergency signals have cleared.

4.0 HAZARDS AND PRLCAUTIONS Since the Auxiliary Building ventilation System is ventilat-ing potentially contaminated spaces the system must be considered potentially contaminated.
Special care must be exercised when changing exhaust filters expecially after their use during a radioactive contamination emergency.
In a high radiation ;mergency, after radiation monitor HP-R-228 stops the supply fans, and the inlet damper shuts, the exhaust fans will continue to run increasing the vacuum in the Auxiliary Building.
The vacuum may increase co the
~
point (exhaust fans have a 12" W.G.
statie head) where it would be dangerous or impossible to enter or leave the Auxiliary Building while the exhaust fans are running, cecause of abnormally high differential pressure across the doors.
