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.

According to the analysis result of the faults caused plant shut down in Korean nuclear power plants during last 10 years, the share of electrical fault is 21%. The first case was instrumentation and control system faults and it is 30%. And, more than a quarter of the electrical faults are ground faults. Consequently, ground fault protection is one of the indispensable schemes to enhance the reliability of nuclear power plant electric power systems. This paper elaborated the ground fault protection system for the main generator and preferred power supply line of typical type nuclear power plant in Korea and the vulnerability of the ground fault protection system also. Then, proposed the subharmonics voltage injection type ground fault protection scheme as an alternative.
