Filtered venting considerations in the United States
The capability to vent with or without attenuation of fission products exists at some US facilities. In addition, two utilities have proposed enhanced capabilities, and generic enhancements are being considered under a regulatory evaluation of severe accident vulnerabilities at all US commercial reactors. The paper 1) summarizes the history of filtered venting in the US including significant past and proposed related research; 2) summarizes an assessment of the positive and negative safety aspects of venting for a class of 24 US reactors (BWR Mark I), and 3) discusses the regulatory assessments being made of filtered venting as a severe accident management strategy, including potential attributes of both accident prevention and mitigation associated with venting. Lastly, based on a review of available literature on European initiatives, questions are raised; answers to which would significantly help US evaluations. 10 refs., 2 tabs.
