< 5.1 Purpose - The purpose of this procedure'is to provide guidelines for obtaining samples from the Post-Accident Sampling Station following i accident conditions.

l~ EP-231, R2v. 11 Pr:ga 12 of 62 CLE/TJY:jmv 5.2 Criteria for use ,

5.2.1 This procedure shall be implemented when a sample shall be taken from the PASS during an emergency situation.

5.2.2 Planned radiation exposures should be limited to the administrative guide levels in Appendix EP-230-1, Emergency Exposure Guidelines.

5.2.3 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.

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 readi,ng 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 cartridge can be made. Set the Switch HC-704 located to the left of the timer. labeled TIME SAMPLE on either YES or NO. *

d. Confirm PI-662 does not rise more than 0.05 psia / min for at least three minutes.

NOTE: i) If PI-662 increases more than 0.05 psia / min.,

this may indicate.high air leak rate into the gas collection chamber. Tighten the septum first and repeat above steps.

i 11) If tightening the septum still yields high i

pressure increases, replace the septum and repeat above steps. If replacing the septum still yields high pressure increases, this indicates a leak in valve or fitting.

j Accuracy of monitoring dissolved gases may be l degraded unless repairs are made at this time.

e. Confirm PI-662 indicates 5.7 psia or lower.

NOTE: If Dissolved Gas Collection Chamber can not be evaucated to below 5.7 psia, this usually indicates the vacuum pump P-701 requires rebuilding or replacement.

f. Turn the Dissolved Gas and Liquid Sample Switch HC-601 to position 1.

AND/OR OBTAINING A LARGE VOLUME LIQUID SAMPLE

41. After final dissolved gas pressure measurement is made, a calculation must be done to determine if a grab sample must be taken. For this calculation, the following dissolved gas

- information is required, P0, PF, temperature of Liquid Loop and Vapor Pressure of Water at the temperature of the liquid loop, PV. -

Contact the Group Leader and have him determine the value of CT in the following equation:

CT = 4.98 (PF - 1.05 PO - PV) (CT is in Scc /KG).

PV is calculated from Table 1 in the Data Sheet for temperature indicated by TI-660, degrees F. Log CT on Item (13) of Data Sheet.

Log PV on Item (12).

42. If CT is greater than 40 SCC /Kg, dissolved oxygen may be reported as less than 0.1 PPM and proceed to 45. If CT is e

less than 40 SCC /KG, a grab salmple must be taken and analyzed on the gas chromatograph for oxygen and hydrogen.

43. Attach'the long needle to the lcc gas-tight syringe.

Dissolved gas sample can be taken by inserting the long needle attached to a gas-tight syringe through the septum via the needle guide into the gas collection chamber. Allow pressure indicated on PI-662 to stablize. During this time, the syringe.may be supported'by a mechanical support.

Withdraw a lec gas sample and lock syringe. DO NOT WITHDRAW NEEDLE.

Immediately have the HP technician survey the syringe to determine whether the sample should be transported to the lab or injected back into the collection chamber.

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 WITH SYRINGE WITH GAS SAMPLE IN IT SHOULD NOT EXCEED 30, SECONDS'DUE TO POSSIBLE HICH DOSE RATE.

l CAUTION: IF THE SAMPLE IS NOT TO BE TAKEN TO THE LAB, INJECT SAMPLE BACK INTO THE GAS COLLECTION CHAMBER. TURN SWITCH HC-652 TO LEFT TO RELIEVE PRESSURE AND THEN REMOVE NEEDLE.

r DISCARD NEEDLE AND SYRINGE AS HIGH LEVEL RADIATION WASTE.

l HIGH DOSE RATE WILL BE DUE TO WATER ACCUMULATED IN SYRINGE.

44. Remove needle and syringe and place in a shielded carrying device for transport to the laboratory.

45. If PI-662 indicates greater than 14.7 psia, turn HC-652 to

, the left to relieve pressure in the gas collection chamber.

46. If a large volume liquid sample is required, turn HC-601 to position 10. Push and hold in CH-629-1 so liquid will be drawn into sample bottle that was positioned earlier under the sample station.. Hold pushbutton for at least 10 seconds.

CAUTION: IF A LIQUID SAMPLE IS NOT REQUIRED, TURN SWITCH HC-601 TO THE OFF POSITION VERY QUICKLY SO THAT THE VALVES CV-620 WILL NOT HAVE A CHANCE TO ROTATE AND ALLOW HOT +

SOLUTION INTO THE LINE AHEAD OF CV-629.

47. Turn HC-601 to OFF.

48. Lower liquid sample bottle into large cask by pulling up on

, the plunger handle. NOTE: Do.not turn or twist bottle while it is on the needles because the needles will bend.

{ 49. Slide the lead shield drawer back into the enclosure to cover opening for-the needles.

50. Lower the cask on the cart by relieving hydraulic: cil pressure with.-the small petcock handle on the hydraulic cylinder.

51. Roll the cask out from under the sample station.and immediately survey the liquid vial and record the Initial Contact Dose Rate on the Data Sheet. Quickly plug cask. Use

-RI-665 to determine Gross Activity of the sample.

52. Switch HC-626 (Liquid Sample Source Selector Switch) must be in position 2 (jet pump) or 4 (RHR) and-HC-700 (Liquid or Gas Selector Switch) must be in the LIQUID position.

53. Adjust PCV-627 on the control panel to have a 15 psi reading on the gauge.

61. Turn Flush Sytem HC-628-1 counterclockwise to position 6 and HC-626 to position 1 and observe that approximately 0.3 gpm flow per FI-664 is occuring. 1 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) Flush for at least'10 minutes and monitor.the flow rate and adjust the nitrogen regulators as necessary during the course of the flush to ensure that 100 psig is maintained on the regulator output.

d) Return the nitrogen regulator to its original setting prior to terminating the. flush. This will prevent lifting of the nitrogen bottle discharge relief valve PSV-30-028.

e) Adjust PCV-627 on the Control Panel to have a 15 psi reading on the gauge.

'62. Drain Collector Tank, Trap and' Sump by turning switch HC-715-1 clockwise through its eight positions pausing approximately 5 seconds at each position.

' the type (s) of surveys to be conducted, and specify I the instrumentation to be used.

2.1.7 Assign a Health Physics Technician to accompany each team entering an area of unknown or suspected adverse radiological conditions.

l 2.1.8 Form Plant Survey Squads as required.

.l EP-251' Rav. 3 Page 2 of 5 l TJM/AJP/mla, 2.1.9 Entries into high radiation areas or areas suspected to have high radiation within them require at least two persons, one of which is an B7.

2.1.10 Prepare ERWP per'EP-401 if required and brief the technician / team.

2.1.11 Planned radiation exposures should be limited to the administrative guide levels in Appendix EP-251-1, Emergency Exposure Guidelines.

2.1.12 Unless specific needs dictate, in-plant radiation surveys should be conducted in conjunc't ion with entries performed for other purposes. ARM readings should be used in lieu of pre-entry surveys whenever possible.

2.1.13 Unless information or data is available~(eg. recent samples from other entries, process radiation monitor data, vent stack readings, etc.), airborne radioactive materials are presumed to be present in all affected

areas of the plant. Respiratory protection requirements are to be based on available information.

. 2.2 Plant Survey Scuad Members shall:

2.2.1 Check that all squad members are properly clothed and equipped with appropriate dosimetry and respiratory protection per the Emergency. Radiation Work Permit l (ERWP) contained in EP-401 when applicable. '

2.2.2 Question that all squad members know where they are

, going, how'to:get there, and what they,are expected to do.

2.2.3 Check that at least one squad member is equipped with an operating, . calibrated lapel air sampler or obtain air sample data using other types of sampling equipment.

2.2.4 Check that the squad is equipped with any needed tools or equipment, e.g., shielded container for samples, reach rods, etc.

,, 2.2.5 Check that the maximum allowable exposures are known and understood by the team members.

2.2.6 obtain the survey instruments specified by the Plant 4 Survey Group Leader and check that they are calibrated

, . and operable.

2.2.7 Estimate exposure accumulation for the job including transit time to and from the work area.
