POST ACCIDENT SAMPLING -

PCS LIQUID/GAS AND CONTAINMENT AIR 1.0 PERSONNEL RESPONSIBILITY The Operations Support Group Leader in the Technical Support Center (TSC) shall initiate this procedure.

In the absence of the Operations Support Group Leader, the Site Emergency Director shall delegate this responsibility.

The Operational Support Center (OSC) Chemistry Supervisor shall implement this procedure.

2.0 PURPOSE 3.0 3~ 1

.J-.2 3.3 3.4 4.0 4.1 To describe the sequential method of sampling the Primary Coolant System and/or the Containment Atmosphere during a post accident condition using PASM.

Additionally, a ring TLD shall be worn on both index fingers with the TLD faced inward.

4.2 ANTI-CONTAMINATION CLOTHING REQUIREMENTS Minimum clothing shall be determined by the OSC Health Physics Supervisor.

Any persons who will handle samples shall wear lineman's gloves, or heavy rubber gloves in addition to their other clothing.

4.3 GENERAL RADIOLOGICAL PRECAUTIONS

a.

Sampling with general area radiation levels in excess of 10 R/hr shall not be performed without the approval of the Site Emergency Director

PALIS~ES NUqLEAR PLANT EMERGENCY IMPLEMENTATION PROCEDURE POST ACCIDENT SAMPLING -

PCS LIQUID/GAS AND CONTAINMENT AIR When conditions warrant, more conservative stay times may be appropriate.

Proc No El-7.1 Revision 9 Page 2 of 31

b.

Stay times for technicians performing post accident sampling shall be based on the formula:

Stay Time = RQ x 0.9.

DR Where:

"RQ" is the individuals remaining quarterly exposure and "DR" is the area's general. area dose rate.

The Radiation Safety Technician shall ensure that the Chemistry Technician reads his dosimeter frequently and does not exceed 90% of his remaining quarterly exposure.

Hand :handling :of.. samples' shall. be *minimized. -~*When *.samples must* be

handled,: a.: beta* radiation :.dose rate:*.reduction: can :be assumed for lineman's gloves *. Dose to,the extremities shall*be.*limited to 7.5R as measured by the ring* TLD pending a.**dose determination based on the beta/gamm~ TLDs.

Heavy rubber gloves may be substituted.

When not being handled, samples shall be stored in a shielded or remote location. All open samples should be handled in vent hoods.

4.6 If problems are encountered in,operating the PASM panel contact the

  • OSC Chemistry Supervisor prior to proceeding.

4.7 In all instances where flush or purge times equal or exceed 2 minutes, consideration should be given to moving to a lower dose rate area, when possible, depending on panel area dose rat.es.

4.8 CV-1910 and CV-1911 will close on a high containment radiation alarm or a high containment pressure alarm.

In order to sample through PASM, these valves must be opened through a special jumpering procedure (see EI-7.0, "Emergency Post Accident Sampling Decision Process", Attachment 1).

A qualified Health Physics Technician shall accompany the Chemistry Technicians to the PASM Panel (Room 233) and a second Health Physics Technician should accompany the Chemistry Technicians* to the Analysis Station for monitoring during analysis.

a.

An air sampler shall be set up for continuous sampling during the Post Accident Sampling Process.

b.

Monitor the area in front of the sample panel during all sampling operations.

c.

Monitor all PASM samples for beta and gamma radiation.

Procedure Steps 5.2 through 5.8.3 may be perofme_d in' any order.

PASH PAREL PREPARATION A checklist in the right-hand margin is to be used by "checking" (/) each blank as that step is being performed.

A copy of this procedure can be obtained from the OSC Chemistry Supervisor-or-from the PASM Supply-Cabinet so that-the checklist can be implemented.

As one Chem.Tech is checking out the PASM Panel per this procedure, the other Chem Tech shall open up the PASM Supply Cabinet and PASM Analysis Cabinet.
