DESCRIPTION OF CHANGES
Justification (required for major revision)
This is a major revision to remove reference to a chemistry calculation number that has changed. In lieu of referencing the specific chemistry calculation, a reference to the Instrument Master Data Sheet (IDMS) is more appropriate as the setpoint is directly controlled by the IDMS.
Page(s) Description (including summary, reason, initiating document, if applicable) 4 Removed reference to Chemistry calculation CH-98-002 and replaced with reference to IDMS for each instrument. AR-CR 437296 9 Removed reference to CH-98-002 and replaced with reference to TSC-RIS-1A,

1.0 PURPOSE
This procedure provides instructions for operating the Technical Support Center (TSC)
Ventilation System Radiation Monitoring System TSC-CP-RAD/1.
2.0 DISCUSSION
The TSC Ventilation System_Radiation Monitoring System continuously monitors and provides alarms for elevated airborne contamination levels in the TSC during an emergency.
TSC-RIS-1A is the TSC Airborne Particulate Radiation Monitor, TSC-RIS-1 Bis the TSC Airborne Radiation Monitor for Iodine and TSC-RIS-1C is the TSC Airborne Radiation Monitor for Noble gas.
The Instrument Master Data Sheets (IMDS) provide the setpoint information for TSC-RIS-1A,
-1 B and -1 C. The setpoint value is selected to allow operating margin between the IMDS limit and actual setpoint. The value in the IMDS is based on the requirement for posting areas above 0.3 Derived Airborne Concentration (DAC) as an airborne radiation area. This will provide High and Hi-Hi alarm set points equivalent to 0.3 DAC and 1.0 DAC, respectively, for a condition which affects TSC habitability.
3.0 RESPONSIBILITIES
- The OSC Health Physics Technician assigned to perform TSC Habitability functions is responsible for performing'tasks controlled by this procedure.
4.0 PRECAUTIONS AND LIMITATIONS
4.1 TSC-CP-RAD/1 audible alarm is loud. Hearing PPE should be worn while working at this panel.
4.2 During Start-up and Operation of the TSC-CP-RAD/1 unit, the "FAIL" alarm may actuate (e.g.,
low flow, low counts, high voltage etc.).
, 4.3 The photomultiplier tubes are light sensitive and can easily be damaged from normal light intensities with high voltage to the detector. Do not remove the shield plug/filter housings potentially exposing the detector' assemblies to light.
4.4 Air Handling Unit fan motors can start and stop at any time. Be aware of rotating equipment located behind equipment guards and shrouds.
4.5 During initial start-up phase, the RIS LOW COUNTS indicating lamps may illuminate for up to 30 minutes due to low down scale indication.

NOTE: Attachments 8.1, 8.2, and 8.3 provide pictures of panels with locations of switches called out.
5.1 To Start Up the System
5.1.1. PROCEED to. TSC-CP-RAD/1 TSC Radiation Monitoring System Equipment Rack, located in the TSC Mechanical Equipment Room. See Attachment 8.1.
5.1.2
- ENSURE TSC-RIS-1A, 18, and 1C "POWER" and "HIGH VOLTAGE" are OFF '
(pushbuttons not depressed) and indicator lamps of each are not illuminated.
5.1.3 ENSURE that the iodine charcoal cartridge and particulate filter are in place and in satisfactory condition per the following substeps:
- a. OPEN the lower front panel to access the front of the detector housing.
NOTE: A small radioactive "keep alive" source is located inside the sample holder assembly, under the cartridge. Use care not to dislodge the source when removing and replacing charcoal filter cartridges.
- b. REMOVE the IODINE shield plug/filter holder assembly AND CHECK that the charcoal cartridge is in place and in good condition. Replace if necessary.
- c. REPLACE the IODINE shield plug/filter holder assembly.
- d. CLOSE the lower front panel to access.
- e. PROCEED to the back of TSC-CP-RAD/1 cabinet.
- f. OPEN the back panel door to access the back of the detector housing.
- g. REMOVE the PARTICULATE shield plug/filter holder assembly AND CHECK that the particulate filter is in place and in good condition. Replace if necessary.
- h. REPLACE the PARTICULATE shield plug/filter holder assembly.
- i. CLOSE the back panel door.
5.1.4 PROCEED to power panel PP-TSC1, located on the wall behind TSC-CP-RAD/1.
See Attachment 8.2.
5.1.5 OPEN the panel door on PP-TSC1.

CAUTION System Startup may cause audible alarm and "fail" light(s) to come in (and then eventually clear). Hearing PPE should be worn while working at this panel due to the audible alarm potential.
5.1.6 ENSURE that'PP-TSC1 Breaker 11 is ON.
5.1.7 CLOSE panel door on PP-TSC1.
5.1.8 RETURN to TSC Radiation Monitoring System Equipment Rack TSC-CP-RAD/1.
5.1.9 ENSURE the Sample Pump is operating as per the following substeps:
NOTE: TSC-RMS-FN/21 rotates to the left (CCW) to the RUN position; STOP position is to the right (CW). This is reverse operating from most switches.
- a. IF TSC-FN-21 is not already running (Green STOP lamp illuminated),
THEN PLACE TSC-RMS-FN/21 switch in the RUN position
NOTE: It takes 30-40 seconds to see proper flow indication for TSC-FN-21.
- b. ENSURE the Red RUN lamp is illuminated.
5.1.10 Startup TSC-RIS-1A, 1B, and 1C as follows:
- a. DEPRESS the "OFF-PWR" pushbutton (bottom switch) on each RIS and ensure that each red Power LED is illuminated.
- b. DEPRESS the "OFF-HV" pushbutton (second switch up from the bottom) on each RIS and ensure that each red High Voltage LED is illuminated.
- c. MARK down the start time. ------
5.1.11 OPEN the soft key access cover located on front door of the recorder below TSC-RR-1 LCD Display. See Attachment 8.3.
5.1.12 PRESS the "Start" soft key on TSC-RR-1 and verify the green LED (record) light illuminates.

NOTE: The following Steps are to be performed upon the termination of a
5.2 To Shutdown the System
CAUTION
Powering down, turning off the High Voltage, or Low Flow for the RIS units may cause the alarm to actuate. Hearing PPE should be worn while working at this panel.
NOTE: TSC-RMS-FN/21 rotates to the left (CCW) to the RUN position; STOP position is to the right (CW). This is reverse operating from most switches.
5.2.1 PLACE TSC-RMS-FN/21, fan switch in the STOP position. The LOW FLOW light will illuminate, and audible alarm will actuate (actuation may be delayed 20-30 seconds).
