215:2 Alarms, both visibic and audibic, are also provided which operate when:
The air flow rate becomes either too high or too low.
The filter breaks or fails to advance in the normal' manner.
The valve closure circuit is energized.
The alarms remain tripped until the alarm reset button on the panel front is actuated; the visual unit remains lit until normal conditions are restored.
F!ain Plant Stack Radiation Monitor - Four isokinetic probes are installed T-in the main plant vent stack.
Two probes are calibrated for a stack flow rate experienced during power operation, and two for a purge operation flow rate.
The probes are connected through stainless piping to two sampic effluent lines located within the blonitoring Equipment Building on the roof of the Primary Auxiliary Building.
One sainplo effluent line comprises a fixed particulate filter which may be removed periodically for laboratory analysis, and an iodinc charcoal cartridge which is continuously monitored.
The other sampic effluent line contains a moving particulate filter and gas detector.
124 The iodine detector is a NaI crystal and a count rate meter with a
'singic channel analyzer set to discriminate against all but the I-131 gamnia.
The particulato detector, which views a moving filter tape is a beta scintillation detector with a count rate meter.
The nobl,e gas monitoring channel uses a beta scintillation detcetor identical to the one in the particulate channel, and also has t. count rate meter.
The three count rate meters are identical except for the singic channel analyzer included in the iodinc channel.
Each has a five decado range from 10 to 106 counts per minute, and is equipped with a two Icvel alarm system.
Both indication and alarm appear locally at the detector cabinet, and in the Main Control Room chart recorders and alarms are provided for all three channels.
Each channel alarms at a preset high levci, and in the event of loss of signal, loss of high voltage, detector failure, or any other failure resulting in a preset low reading.
Each of the two pumping systems is provided with a high and low flow alarm in the Main Control Room.
The sensitivity of the partictilate channel is such that a concentration of 5 x 10-12 pCi/cc of gross beta activity will produce a counting rate of approximately 90 C/M above a background coun On the noblegaschanndi,aconcentrationof3x10~gingrateof30C/M.
pCi/cc of Xc-133 will produce a counting rate of SS C/M above a background of 30 C/M.
The iodine channel can detect a count buildup of approximately 17 C/M per hour of co11cetion above a 30 C/M b;tekground.
Three motor driven upscale check sourec: which may be actuated locally at the detcetors and remot cly in the Main Control Room will check the operation of each channel.

215:2a l124 Component Cooling h'ater D,ctec_ tor - The com;ionent cooling water detector r
is a. single Geiger-Muller tube, together with an impedance matching circuit, housed in a ucatherproof probe.
The detector assembled in' its housing is inserted in a thimble welded into the main return pipe upstream from the component coojing pump suction block valves.
The component cooling water detector continuously measures the activity of the component cooling water.
A high activity indication closes a solenoid operated trip valve in the vent line of the component cooling water surge tank.

215:4 Air E.iector Effluent Detector - The air ejector effluent Icak detector is
~
a scintillator together with impedance natching circuit and is housed in a weatherproof probe.
The detector and its housing is nounted in the air ejector effluent line to the primary auxiliary building exhaust fan suction.
The Icak detector is a medium sensitivity beta-ganma detector, with a sensitivity range of.01 to 10 nr per hr, with a ganna energy response of 0.25 nov to 2.5, and a beta energy response above 0.154 nev.
The computer-indicator, nounted on the radiation monitoring equipacnt panel, includes a pulse amplifier and a lo'garithmic count-rate integrator and noter amplifier.
The indicator includes a background flasher, alarm lamp, and indicating noter.
The conputer-indicator has a range of 1 to 1,000 counts per second on a 3 decade log scale.
Provision is also nade to operate a recorder and an alarm circuit with visibic and audibic indications.
The alarn remains tripped until the alarn reset button on the panel front is actuated; the visual unit remains lit until normal conditions are restored.
Radiation Monitoring Equipment Console - A radiation nonitoring equip =cnt console is located in the control roca.
A console consists of two cabinets provid'ing nounting space for eight channels (conputer-indientors), a relay unit and a calibration unit, a power distribution panc), a plate voltage and filament power supplics.
Line regulators are also nounted in the cabinet.
The radiation nonitoring equipnent exclusive of the detcetors is mount ed in equipment rachs.
All equipment housed in the two cabinets, except for the power supplies, is nounted in pull-out drawers for casy access.
A large renovabic door allous entry to the rear of each rack.
A single equipment console in the Main Control Roon houses the particulate, nobic gas,'t.nd radiciodine nonitors fo'r the plant vent stack, including chart 124-recording and alarns.
Site and Portable Radiation Detection Eculpnent General - The site and portable radiation detection equipment includes the instrumentation required for providing the radiation level information necessary for the protection of plant' personnel and for detcraining an,y increase in normal background activity of the plant site.
The details of the use of all the equipacnt listed are described in Section 507, RADIOLOGICAL llEALTil AND SAFETY, Dosineters and Filn Badees - Personnel dosinetry and film badges /TLD's are provided to neasure integratcJ exposure on all personnel working in contani-nated areas.
The dosimeters are the direct reading type.
Ibnd and Foot Menitor - A hand and foot monitor is located adjacent to the entran c of the lockerroon.
This unit nonitors both hands anti feet sinultaneously.
