Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Senate committee hears from energy secretary nominee Chris Wright
Wright
Chris Wright, president-elect Trump’s pick to lead the U.S. Department of Energy, spent hours today fielding questions from members of the U.S. Senate’s committee on Energy and Natural Resources.
During the hearing, Wright—who’s spent most of his career in fossil fuels—made comments in support of nuclear energy and efforts to expand domestic generation in the near future. Asked what actions he would take as energy secretary to improve the development and deployment of SMRs, Wright said: “It’s a big challenge, and I’m new to government, so I can’t list off the five levers I can pull. But (I’ve been in discussions) about how to make it easier to research, to invest, to build things. The DOE has land at some of its facilities that can be helpful in this regard.”

A methodology for reliability allocation in nuclear power plants, which determines reliability characteristics of reactor systems, subsystems, and components (low-level criteria) that are consistent with a set of top-level performance criteria such as the likelihood of core damage, adverse health effects, and associated economics is presented. The methodology, based on the multiobjective programming technique in a decision-theoretic approach, does not require elaborate value judgments in determining the low-level criteria. Central to the methodology are the concept of noninferiority and finding the noninferior solution set. Several results of the methodology application to a realistic problem are also provided.
