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.”

The parameterized formulas of isomeric cross-section ratios, including two adjustable parameters for (n,2n), (n,p), (n, α) reactions at 14.5 MeV, have been derived with some approximations based on the Hauser-Feshbach theory. By fitting these formulas to available data, these parameters have been extracted, and the systematics behavior of the isomeric cross-section ratios has been studied. More accurate and reasonable predictions than before were obtained by using these parameters and the systematics formulas.
