.to the level of the moisture separator when this action is not-inconsistent with station emergency procedures. This

-will fully flood the separators and will provide a-thermally-induced recirculation flow path for mixing.

5.2.3. Plann'ed radiation exposures should be limited to l

the administrative guide levels in Appendix EP-f 230-1, Emergency Exposure Guidelines.

5.2.4 There is no automatic drain or blow down but there is an alarm light to indicate that the level in the trap T-717 is high and that the i trap needs to be drained right away. This trap removes water from the gas sample lines. If the liquid' level becomes too high, water will be sucked ~into the gas breakdown pump and 6

mechanical damage may result.

on the filter cartridge will not be unnecessarily high and '

cause special handling problems. Observe the RI-704 reading to determine if there is a rapid activity buildup. Set the Switch HC-704 located to the left of the timer labeled TIME l

5 If the bottle does not fit snugly, use a small pad of rubber or

felt, thick enough to hold vial against the upper yoke of the vial holder and/or attach the bottle to the vial holder with Velcro tape.

, 14. Check that the small volume cask is in the cask positioner, and that both are hanging from the hooks below the sample station.

CAUTION: THE LEAD SHIELDING DRAWER WEIGES APPROXIMATELY 70 POUNDS.

15. Swing the cask into position.under the sample station (ensure

notches of positioner are located on the inside of the sample enclosure frame) and lock the arms of the cask holder so the cask and bottle will remain in position.

Allow pressure indicated on PI-662 to stablize. During this time, the syringe may be supported by a mechanical support. Withdraw a 5cc gas sample and lock syringe. DO NOT WITHDRAW NEEDLE.

If PI-662 indicates greater than 14.7 psia, turn HC-652 to the left to relieve pressure in the gas collection chamber.

WARNING: HAND CONTACT WIT 3 SYRINGE WITH GAS SAMPLE IN IT SHOULD HWHEEED 30 SECONDS DDE TO POSSIBLE HIGH DOSE RATE.

CAUTION: IF RADIATION MONITOR ALARMS AT 1500 REM /HR, INJECT M BACK INTO THE GAS COLLECTION CHAMBER. TURN SWITCH HC-652 TO LEFT TO RELIEVE PRESSURE AND THEN REMOVE NEEDLE. DISCARD NEEDLE AND SYRINGE AS EIGH LEVEL RADIATION WASTE. HIGH DOSE RATE WILL BE DUE TO WATER ACCUMULATED IN SYRINGE. REPEAT ENTIRE DISSOLVED GAS PROCEDURE.
