3.1 DESCRIPTION

The Post Accident Sampling system is an on-line system designed to sample and evaluate various liquid and gaseous sample streams during accident conditions. The Reactor Building Atmosphere and Noble Gas Effluent Monitoring Subsystem (RANCE) samples the RB atmosphere and gaseous effluents from both the RB and AB Vents.

The Post Accident Sampling system provides a means of performing an in-line gama isotopic analysis and gas grab sample, of the RB atmosphere.

3.2 LIMIi_k_fRECAlITTONS 3.2.1 Performance of all or part of this procedure will be done by direction of the Emergency Coordinator.

3.2.2 Entries into the controlled access must have Radiation Monitoring Team preplanning, concurrence, and coverage as outlined in EM-209, Re-Entry Proccdure.

3.2.3 During post-accident sampling, extremely high radiation exposure levels could be experienced.

The ability to perform this procedure and stay within exposure limits will require ALARA pre-planning.

3.2.4 Return to the Lab if the dose rate at places requiring work is >

15R/Hr.

The 4 REM Tctal Effective Dose Equivalent (TEDE) whole body exposure limit will be exceeded in 16 minutes at 15R/Hr.

3.2.5 All sampling actions are performed at the Ma,in Control Board by l

Operations or in the Count Room either on the VAX Computer or from CMP (RANGE Mimic Panel) unless otherwise noted.

3.2.6 Section 4.1 mutt be completed prior to any sample team re-entries.

3.2.7 WS-13-CE (RANCE AIMS) can measure 1.0E-6 Ci/cc to 1.0E+5 Ci/cc for the Reactor Building Vent sample point.

3.2.8 W5P-1 may be damaged if operated without complete line-up.

WSP-1 is a positive displacement pump.

3.2.9 WSV-70 is interlocked with the following valves and will not open if any of these valves are open, o W5V-33 o WSV-35 i

o WSV-56 l

3.2.14 Samplit.g via WSV-3 and WSV-4 is least preferred because sample may not be representative of RB atmosphere.
