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.

This Note analyzes the availability of supervised protective systems for nuclear reactors. Failure and repair times are assumed to be exponentially distributed. The availability is maximized, subject to a given fixed amount of resources, by determining the optimum distribution of resources between supervision and repair facilities and by selecting the optimum active-inactive times of the supervisor. The mathematical formulation employs a Markov model continuous in time and alternating between two and three discrete states. Maximization of availability is achieved by using a modified pattern search technique. Computer results illustrate the usefulness of the approach.
