Overview of filtered containment venting system in Nuclear Power Plants in Asia

Presently, Asia is a region where nuclear energy grow fast. To ensure nuclear safety, the FCVS is being taken into account in the SA mitigation strategy by regulatory authorities. Chinese nuclear safety administration requires NPPs to have adequate and reliable containment venting system. Thus FCVS is either equipped or about to be equipped on most reactors operating or under construction in China. Nuclear companies and research institutions are conducting research and engineering works about FCVS design and function. In South Korea, a government funded project was carried out during 2013-2017, aimed to design a domestic FCVS technology. Confirmatory tests have been performed to evaluate the function of designed FCVS. In Japan, Tokyo Electric Power Company started installing FCVS on the NPPs since 2013. Related research work is performing in Japanese universities and institutions. Taiwan's Atomic Energy Council also requests utility companies to reexamine the present emergency operation procedures and study the strategies such as the addition of required facilities for SA prevention and mitigation in each NPP. It is noticed that India is also investigating the options to mitigate the SAs, including FCVS.
