1.2 Summarv Descriction of the Svstem (Refer to B&R Dwc. No. 2028, Rev.
17)
. Gas enters the gaseous waste vent header from various tanks and components throughout the plant.
Some of the collection points are open continuously to the vent header, whereas others are only vented when it is necessary to vent gas from the tank or component.
The relief valve portion of the vent header vents directly to the vent station.
Two Waste Gas Compressors are provided to take suction from the vent header and deliver the gas to the Waste Gas Decay Tanks.
One compressor normally pumps into the selected Waste Gas Decay Tank The second compressor in automatic
- standby, starts with an increasing vent header pressure.
The gas is normally retained in one Waste Gas Decay Tank to allow radioactive decay, while the other tank is in service.
G:s. in the vent header and the waste gas decay tanks, is continually sampled for hydrogen and oxygen in the gas analyzer of the Nuclear Sampling System.
In addition.
activity levels are verified periodically in each Waste Gas Decay Tank by sampling, and continually during a release by radiation monitors at the outlet of each tank and at the common outlet to the unit vent.
The radiation monitors, at the outlet of each tank. provide alarms and send a signal to automatically shut the respectite flow centrol valve on a
~
high radiation condition. 'The ccamon ' outlet radiation k.onitor
- provides an alarm and sends a signal to shut both tank outlet flow control valves on a high radiation condition.
Gas from the Maste Gas Decay Tanks may be dischargsi to the Reactor Coolant Biced ?!ald-up Tanks in lieu of the unit vent if the activity.
e c.
s 4-level is not sufficiently low.
The Radwaste Disposal Gas System is controlled from Radwaste Panel No. 302B in the Auxiliary Building.
1.3 Svstem Desicn Recuirements Each Waste Gas Decay Tank is sired to receive the radioactive gaseous release of the plant following a cold shutdown and subsequent startup, and store this gas for ninety days to i
allow for radioactive decay.
The entire system (both Waste Gas Decay Tanks) can accomodate the gases generated from two cold shutdowns at the end of a fuel cycle, assuming 100%
evolution of radioactive gases from the reactor coolant with a 1% fuel cladding defect.
This will pressurize both Waste Gas Decay Tanks to 100 psig.
That portion of the Radwaste Disposal-Gas System from inside dhe Reactor Building, up to and including valve WDG-V199 is d'esigned for 700 psig.
Down-stream of valve WEG-V199 it is designed for 150 psig.
The entire system is classified as seismic Class I and is designed, constructed, and erected in accordance with ANSI B31.7, Nuclear Piping.
Each compressor can compress 40 scfm to a pressure of 110 psig although 20 sc5n is the largest expected requirement.
2.0 DETAILED DESCRIPTICU OF THE SYSTEM 2.1 comeop.cnts 2.1.1 Vent Header All potentially radioactive gas frcm tanks and components vents to the vent header or the relief valve vont header.
The pres-sure in the vent header is maintained betwoon 2.5 and 5 psig operation of the Waste Gas Compressors.
The Reactor Building vent header can be isolated from the remainder of the vent system by 4" Reactor Building Isolation Valves WDG-V2 and KEG-7199.. ;
.t.
..v.
2.1.2 Waste Gas Compressors WDG-P-1A. NDG-P-1B Two gas compressors (Table 2) are provided to take suction on the vent header and relief valve vent header and compress the gas for storage in Waste Gas Decay Tanks.
The compressors are located in the Auxiliary Building at elevation 305' and are powered from MCC's 2-32A and 2-42A respectively.
The compressors operate on a seal water prin-ciple.
The amount of seal water is maintained in the discharge separator by an automatic level centrol system and is supplied frcm the Demineralized Water System.
High seal water level in the discharge separator is automatically drained to the Auxiliary Euilding Sump Tank.
Each compressor is also pro-vided with an automatic inlet pressure control through pressure control valves WDG-V84A and B.
respectively.
Gas unlcader valves WDG-V72A and B respectively prevent the compressor from starting against full diccharge pressure and prevent excessive internal lobe pressure from damaging the compressor.
The compressors, supplied by Nash Engineering Co., are described fully in the manufacturer's technical manual ( 5 ',. 00 ).
The moisture separator is cooled by Nuclear Service Closed cooling water.
The compressor valves are supplied with Instrument Air.
For explanation of the logic of the compressor associated
' valves see Table 4.
2.1.3 Waste Gas Dec3v Tanks NDG-T-1A and WDG-T-1B Two 1937 cu. ft. 14,500-gallen. 304 SS. Waste Gas Decay Tanks (Table 1) are provided for the storage and decay of radioactive gas at elevation 305' in the Auxiliary Building. Each tank is provided with instrumentation which provides indication of a high pressure and/or high liquid lovel alarm on Radwaste Panel No.302
- 3. With high liquid level the tank drain valve openu and drains to the Auxiliary Building Sump Tank.
The Decay ranks - -..
are also provided with relief valvos (WDG-R2A and WDG-R2B), sat at 120 psig.
These valves relieve directly to the unit vent to protect the tanks against damage from overpressure.
2.1. 4 '
Waste Gas Filter WDG-F-1 The Waste Gas Filter (Table 3) is located in the 3" line leading from the Wast Gas Decay tanks to the unit vent or to the Reactor Coolant Bleed Hold-up Tanks.
The Waste Gas Filter consists of three filters:
the prefilter, absolute filter, and charcoal filter, housed in a 304 S.S. pressure vessel.
The flow through the filter assemble is manually regulated to maintain a flowrate of less than 100 scfm.
The prefilter is 90% efficient for particles larger than 1 micron, the absolute filter has a maximum efficiency of 99.97% for particles larger than 0.3 microns and the charcoal filter is capable of removing 99.9% of radioactive iodine in vapor fomm from the gas stream.
The filter assenbly is replaced when radioactivity level in the filter reaches a predetermined value (approximately 3 millicuries) or when the differential pressure drop across the filters reaches the value recc= mended by the manufacturer (approximately 3" H O)
- 2 Instrumentation is provided to measure the differentail pressure across the filter assembly and provides an alarm on Radwaste Panel No. 302B.
If the filter housing pressure reaches 150 lbs.,
a relief valve (WDG-R4) will relieve pressure to the unit vent.
A '5" drain is provided on the filter hous ing for drainage purposes.
The Waste Gas Filter is located in the Auxiliary Building at elevation 305'-0".

2.2 Instruments, Controls, Alarms, and P rotective Devices 2.2.1 Instrument and Controls Controls and oressure j'.istrumentation for operation of the Radwaste Corpressors are located on Radwaste Panel 302B.
Pressure and level of the Waste Gas Decay Tanks is provided on the Radwaste Panel to give indication and alarm conditions.
Radiation monitors are provided to measure and record the activity of gas as it leaves each Waste Gas Decay Tank and again prior to being discharged through the unit vent.
The radiation detector at the unit vent is interlocked with the Waste Gas Decay Tank outlet valve (WDG-V3CA and WDG-V30B) to shut on a high radiation signal.
See Radiation Monitoring system description (Index No. 52) for tha s etp oints.
See Table 5 for information on the instrumentation and controls of the system.
2.2.2 Alarms See Table 6 for panel mounted annunciators.
2.2.3 P rotective Devices Under conditions of a LOCA, the Safety Features Actuation System will isolate the Reactor Building vent header from the remainder.of the vent gas system by closing valves WDG-V2 and NDG-V 199.
The Reactor Building vent header is orotected from overpressurization by relief valve WDG-R3, which ocens to the Reactor Building atmosphere if the cressure reaches 150 osig.
Relief valves WDG-R2A and WDG-R2B 'crotect the Naste Gas Decay Tanks (WDG-T-1A and WDG-T-13, resp ec tively) frc over-pressurizing.
They relieve to the unit vent if the pressure 1
- in the tanks reaches 120 psig.
Each comoressor (secarator section) is orotected from over pressure by a relief valve (WDG-RSA and SB) set at 115 psig,
'and dischargos to the Auxiliary Building Sump Tank.
3.0 PRINCIPAL MCDES OF CPERATION 3.1 Start-uo The vent header in the Auxiliary Building is normally always in service since several tanks or ccmponents are continually vented to the vent header.
Manual venting of certain other comoonents, such as demineralizers and filters, is cerformed as coerations dictate.
Additionally, the Reactor Building vent header is valved into service when the reactor is shut down for.
maintenance and/or refueling.
3.2 Normal Or.eration The Waste Gas comoressors collect gas from the vent header and comoress this gas for storage into one of the Waste Gas Decay Tanks.
The contents of the other Waste Gas Decay Tank decays for oeriods of uo to ninety days, after which the gas is bled to the unit vent or the Reactor Coolant Bleed Holdup Tanks.
The selected coerating compressor is controlled to start at 5 psig in the vent header and the backup compressor starts at 8 psig.
Each comnressor has a four position control switch located on P anel 302B, which allows selection of the operating and back-no comarcssors.

- compressor runs continually.
~2.
Pull-to-Leck - control circuit disconnected, compressor does not run.
3.
Auto Hich - compressor starts at 8 psig in the vent header and stops at 2.5 poig.
4.
Auto Low - compressor starts at 5 psig in the vent header and stops at 2.5 psig.
The following components vent to the Reactor Building vent header:
a.
Steam Generators (secondary side) b.
Steam Generators (primary side).
c.
Reactor Coolant Drain Tank d.
Core Flooding Tanks c.
Pressurizer f.
Control Rod Drive Mechanisms The pressurizer and steam generator primary and secondary sides each vent via a 1" pipe, through isolation valves and a sight flow indicator, to the Reactor Building vent header.
The Reactor Coolant Drain Tank and Core Flooding Tanks vent to the Rcactor Building vent header.
Control Rod Drive Mecha~nisms vent through flexible hoses, isolation valves, and liquid detectors into the Reactor Building vent header.
An atmospheric relief valve, WDG-R3, set at 150 psig is pro-
, gided. in. the Reactor.auilding. header..to protect this: section.
of piping.
Any liquid which may carry over to the Reactor Euilding vent header can be drained through 1" drain iso-lation valve s (WDG-V159 & WDG-V160) and an automatic drainer s.
\\
to the Reactor Building floor drains.
The Reactor Building vent header discharges to the main vent header through a 4" check valve WDG-V107.
The vent header receives the folicwing vents:

The vent header discharges through 2" check valve WDG-V58; passes a 3/4 drain, a 1" branch (the Waste Gas Compressor Bypass Inlet Control),
four instrunentation connections, and a 2" branch (Compressor and Decay Tank bypass).
The gas goes through a 2" pressure control valve, WDG-V59, and two associated isolation valves.
The gas then passes a h" branch to the secondary sampling system, and two ccmpressor isolation valve A lh inch connection is provided on the outlet piping of each compressor as a discharge cross-connect through 1 " cross-connect valve WDG-V172.
This allows either ccmpressor to discharge to either Waste Gas Decay Tank.
The cenpressors discharge through a 1" isolation valve, a check valve WDG-VS7A (3), past a lh" branch for a discharge cross-connect, past a 1 " branch for a discharge cross-connect, through ih" W'aste Gas Decay Tank inlet valves WDG-V26A (3) and WDG-V55A (3) into either Waste Gas Decay Tank.
Flow out of the Waste Gas Decay Tank (s) is through 2" outlet valves WDG-V54A (B) and WDG-V30A (3).
Discharge Flow is controlled by manual throttle valve WDG-V188 A (B) with a handwheel c 2tside the tank cubicle.
The valve is positioned so that the dis-chargerate is less than 100 scfm.
The gas is then normally discharged by radiaticn detector WIG-RZ-1485 (1486) through filter WDG-F-1, through two flow orfices, by another radiation detector (WDG-RZ-1480),
through isolation valves and a check valve, to the station vent.
If
- required, instead of discharging to the station vent, gas may be directed to the Reactor Coolant Bleed Holdup Tanks.
The foll'owing tanks /cenponents relieve to the relief valve header:

As with other headers, the relief valve vent header may be drained through 1" drain valves.
A 1" branch is provided on the C0mpressor and Gas Decay Tank,
By-Pass Line downstream of the radiation detectors, through 1" valve WDG-V170 and pressure control valve WDG-V171, and goes to che compressor suction piping upstream of pressure control valve WDG-V59.
This allcws the gas content of one Waste Gas Decay Tank to be pumped into the other tank if this is required.
3.3 Shutdown The R-dwaste Gas System is not normally shut down with the exception of the Reactor Building Header. If, however, it becomes necessary to shut down the remainder of the system, then the ccmpressors are turned off and the headers purged with nitrcgen from the Nitrogen for Nuclear and Radwaste System.

this same line can also be used to release gas directly from l
the vent header to upstream of the Waste Gas Filter.
This operation is only performed if there is a large volume of gas which is at or below allowable discharge limits.
l 3.5 Emercencv In an emergency, the radwaste gas system functions as in normal operation.
4.0 HAZARDS AMD PRECAUTIO:!S Eydrogen concentration must be maintained at less than 3%
concentration in the waste gas headers and the Waste Gas Decay Tanks.
If the hydrogen concentration exceeds 3%,
nitrogen is bled into the waste gas headers or the Waste Gas Decay Tank (s) to dilute the gas to less than 3% hydrogen.
l The greatest hazard of this system is the release of radio-activity to the environment.
To preclude the release of radioactive gases to the atmosphere, observe the following precautions:
a.
Analyze all gases for radioactivity before release.
b.
Manually control all releases.
c.
Monitor redundant radiation detectors located in the discharge line.
If entry is required to an area which contains WDG Gas-both.
the radiolegical and nitrogen (lack of oxygen). hazard.s should i
be considered.
