Control of accidental discharge of radioactive materials by filtered containment venting system: A Review

다국어 초록 (Multilingual Abstract)

Radioactive materials are released from the molten core into the containment at the time of a severeaccident in a nuclear power plant (NPP). Filtered containment venting system is a popular and effectivesafety measure installed to obstruct the uncontrolled escape of radioactive materials due to the overpressurization of the containment. Different designs of filtered containment venting system (FCVS) areavailable today, each being the result of extensive research and development varying in one way or theother. This paper gives an elaborate description of the different types of FCVS currently being used, thecurrent usage status in over 17 countries and the legislations regarding it. The recent researches beingcarried out in this field has also been discussed in detail. This present paper focuses on the critical reviewof existing FCVS, reports the challenges faced by it and highlights the potential developments to overcomethe difficulties.
