Powering the future: How the DOE is fueling nuclear fuel cycle research and development
As global interest in nuclear energy surges, the United States must remain at the forefront of research and development to ensure national energy security, advance nuclear technologies, and promote international cooperation on safety and nonproliferation. A crucial step in achieving this is analyzing how funding and resources are allocated to better understand how to direct future research and development. The Department of Energy has spearheaded this effort by funding hundreds of research projects across the country through the Nuclear Energy University Program (NEUP). This initiative has empowered dozens of universities to collaborate toward a nuclear-friendly future.

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.
