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 logical first step toward incorporating a precompound nuclear reaction theory in the Hauser-Feshbach formalism, widely used for compound reaction cross-section calculations, is to develop unified level density formulas needed for the two parts of the calculation. An advanced, simplified formulation of the spin cutoff factors for particle-hole level densities, based on the uniform pairing model, is presented. This simplified formula, explicitly dependent on the excitation energy and the exciton number, is easy to use for the precompound part of the calculation and is shown to be consistent with the formula used for the Hauser-Feshbach part of the calculation. Differences between the present approach and a previous one are analyzed.
