(?; Station is operable by verifying that RT-5-030-800-0, POST ACCIDENT SAMPLE STATION OPERABILITY TEST, was successfully' performed in the previous six months. 5.2.2 This procedure shall be implemented when a sample shall be taken from the PASS during an emergency situation. 5.2.3= Planned radiation exposures should be limited to the administrative guide levels in Appendix EP-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 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 mechanical damage may result.

l'WHILE. PERFORMING STEP NO. 8 BELOW: a) The nitrogen bottle pressure regulators (PCV-30-073, 074) should be adjusted after the commencement of flush flow such that the outlet pressure gauge' reads 100 psi. (The outlet. pressure normally. drops to.about 70 psi
-after CV-628-opens and flush flow begins.)
b) The piping station pressure _ control valve (PCV-627) should be fully open. Flush flow should now be-approximately 0.5 gpm. c) Monitor the flow rate and adjust the regulators as . necessary'during the course of'the flush to ensure that (' 100 psig is maintained on the regulator output.
'8.- After being assured'that the discharge line to'the suppression pool-is open, drain Collector Tank, Trap and Sump

PROCEDURE FOR OBTAINING A 14.4 ML GAS SAMPLE
- 17. Turn the "15 ml Gas Sample Switch" HC-705 to position 2 and circulate gas for the appropriate time:
Sample Time (min) Drywell Atmosphere 23 Suppression Pool Atmosphere 17 Secondary Containment Atmosphere 9 Be sure that the flow as read by the rotameter (FI-725) thru the sample enclosure window is greater than 10 SLPM. Record flow and flush duration on data sheet.
- 18. Turn HC-705 to position 3 and evacuate the off gas vial.
Record pressure as P1 from PI-708 of the evacuated vial on the data sheet. Make sure the. vacuum in the gas vial reaches a stable minimum reading. +
.19.i Turn HC-705'to position 4, " TAKE SAMPLE". Verify that pressure (PI-708)-does not change significantly. If the pressure changes significantly, it may indicate a system leak. Therefore, turn Switch HC-705 counter clockwise to
-({, position 2. Remove the sample vial and place in a plastic bag for transportation to the hot lab. Place a new 14.4 ml off
^
gas sample vial'into the gas positioner and return to Step 5.
'20. Press the-HC-720 button to obtain the sample. Keep button
- depressed until a steady pressure is reached (approximately 5 seconds). Record pressure as P2 from PI-708 on data sheet.
This pressure should correspond to actual pressure of sample
-- being obtained. Record sample temperature from TI-724 on data sheet.
- 21. Turn HC-705 to position 5 " FLUSH SYSTEM" and flush for approximately 1 minute.
- 22. Turn HC-705 clockwise to "OFF".
- 23. Turn Switch SV57-147A/SV57-147B or SV57-146A/SV57-146B (if opened in Step 14) to the CLOSE position.
I
- 24. Wearing cotton liners and gloves, and observing ALARA-practices, withdraw the gas vial positioner and.immediately have the HP technician survey the gas sample vial and record the Initial Contact Dose Rate on the Data Sheet. Keep the vial at the maximum distance from the individual and quickly-insert the sample bottle into the gas vial-cask. Close and
. latch the gas vial cask. Put a stopper or the gas vial -( positioner back into the port in the sample station.
- 25. Turn HC-700 (Liquid / Gas Selector) to the LIQUID position.

If not, reposition the drawer.
CONTACT THE GROUP LEADER AND VERIFY THE SAMPLING TIME
- 12. Decide whether a timed or non-timed sample is desired and record. Generally speaking, if a high activity condition exists or is suspected, a timed sample should be taken. For a timed sample, set the Timer KC-712 between the range of 0 to 30 seconds. Select a low enough time so that the activity on the filter cartridge will not be unnecessarily high and I cause special handling problems.. It is suggested that 5 l seconds be used for the first try. Observe the RI-704 reading to determine if there is a rapid activity buildup.
This reading will also include non-absorbing gases. If the activity level does not exceed a pre-set value of 40 mR/hr, ( another timed flow through the cartridges can be made. Set the Switch HC-704 located to the left of the timer labeled TIME SAMPLE on either YES or NO.

Put the desired filter. cartridge (s) into the cartridge retainer, put-the cartridge retainer _into the gas filter drawer including "O" rings and put
~ the drawer into the sample station and verify that the
" CARTRIDGE.IN". light is green.. If_not, reposition the drawer.
CONTACT THE GROUP LEADER AND VERIFY THE SAMPLING TIME.
- 14. Decide whether a timed or non-timed sample is desired and record. Generally speaking, if a high activity condition exists or is suspected, a timed sample should be taken. For a timed
' sample, set the Timer KC-712 between the range of 0 to 30 seconds.. Select a low'enough time so that the. activity on.the filter cartridge _will not be unnecessarily high and cause special handling problems. It is. suggested that 5 seconds be used.for the first try. Observe the RI-704 reading to determine if_there-is a rapid activity buildup. This reading will-also include non-absorbing gases. If the activity level does:not
- exceed a pre-set vplue of 40 mR/hr, another timed flow ~through the cartridge can be.made. Set the-Switch HC-704 located'to;the
- left of the timer labeled TIME SAMPLE on either YES or NO.
15~. Adjust PCV-30-127 to 2 psi (located in.back of Control Panel).

Replace the lead cap (liquid position). 2.6.6 If further dilutions.are necessary (per appendix EP-241-1) repeat. steps 2.6.1 thru 2.6.5, always
.beginning with the last dilution vial to accept.a sample aliquot.
2.6.7 When desired dilution is reached, the Health Physics Technician shall determine the dose rate of the diluted sample.
- 2.6.8 If the diluted sample dose rate is unacceptable, repeat steps 2.6.1 thru 2.6.5 until dose rate is acceptable. Indicate additional dilutions on appendix EP-241-1.
2.7 Sample Cup Preparation 2.7.1 For each analysis to be performed (appendix EP-241-1) use the syringe transfer method
. (step 2.6.1) to sequentially obtain the volume of sample required (Appendix EP-241-1) from the appropriate diluted / undiluted sample source (appendix EP-241-1).
DUE~TO THE AMOUNT OF SAMPLE BEING REMOVED FROM THE
- BOTTLE IT MAY BE NECESSARY TO INJECT AN EQUAL AMOUNT OF AIR INTO THE BOTTLE.
2.7.2 Inject the appropriate sample aliquot into its analysis cup.
. DUE TO THE SMALL VOLUME OF SAMPLE USED TO PERFORM PH AND THE EFFECTS CO2 ABSCRBTION WILL HAVE ON THE ANALYSIS, THE PH SHOULD BE DETERMINED IMMEDIATELY AFTER THE SAMPLE IS PLACED IN ITS SAMPLE CUP.

QUESTION. Checking Pump Performance A. Visually check rubber inlet flange for cracks or tears. Replace if' damaged. Tighten inlet clamping nut. B. Valve Leak Check
- 1. Insert a fresh sealed detector tube into pump.
Misalign red dots on pump and. handle. Pull several fairly rapid continuous full pump strokes. Pull handle out 6 mm (1/4 inch) and hold in this
~
2. position for 1 or 2 seconds.
- 3. Release handle.
- 4. If handle returns to within 1.5 mm (1/16 inch) or less of fully closed position, continue to step C.
- 5. If handle does not return to within 1.5 mm (1/16 inch) of fully closed position (or less) , consult chemistry Supervision.
C. Field Volume Check
- 1. Insert a fresh sealed detector tube into pump.
- 2. Align red dots on pump body and handle.
- 3. Pull handle firmly and at a moderate speed until handle locks into position. Wait 1 minute.
- 4. Unlock handle by turning it and~ guide it back.
TO PROTECT PUMP STOPPER from breakage, do not release the handle and allow it to spring back when conducting a leak test. Make sure you hold your hand onto the handle and guide it back. y'
