Report: New York state adding 1 GW of nuclear to fleet
New York Gov. Kathy Hochul has instructed the state’s public electric utility to add at least 1 gigawatt of new nuclear by building a large-scale nuclear plant or a collection of smaller modular reactors, according to the Wall Street Journal.

When a severe accident occurs, steam, hydrogen, non-condensable gas, and radioactive materials are generated and released from reactor coolant system (RCS) to containment atmosphere resulting in increase of containment pressure. The generation of steam and noncondensable gas could affect containment integrity which is a final barrier of radioactivity release. To prevent overpressurization of containment and to reduce the amount of radionuclides release to the environment, the concept of Filtered Containment Venting System (FCVS) is adopted. However, the operation of FCVS is needed to be careful because it emits radioactive materials into the atmosphere which can affect to the public and environment ultimately. Especially, the Cesium (Cs) could have a major impact on human health and ground contamination. In addition, the effects of FCVS differs depending on accident scenarios and venting strategies. Therefore, in this paper, the effects of FCVS operating strategies on the Cesium during severe accidents are analyzed. Consequently, this study suggests the optimum venting strategies of FCVS in order to minimize the amount of Cs released to the environment.
