Preliminary evaluation of the gaseous effluent sampling system at the 296-S-18 stack, 242-S evaporator
This evaluation of the 296-S-18 stack sampling system is part of a larger study, sponsored by ARHCO and conducted by Battelle-Northwest, of gaseous effluent sampling systems in ARHCO facilities. It is the fourth and last in a series of evaluations of tank farm stack sampling systems. The objectives of this study are: Evaluate the compliance of the existing effluent particulate sampling system with ARHCO`s Interim Criteria for such systems by using sampling theory and radioactivity counting statistics; and make recommendations for corrective action which will lead to a particulate sampling system in compliance with the Interim Criteria. This study is considered preliminary because no experiments have been conducted to verify the sampling system`s performance. The following report includes a brief summary, a detailed description and evaluation of the sampling system, conclusions about satisfactory or deficient areas of the sampling system and recommendations for corrective action. The appendices contain a copy of the Interim Criteria and the applicable ARHCO Emergency Procedure for radioactive gaseous discharges.
