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.”

Cross sections for the 109Ag(n,2n)108mAg reaction are measured using an activation method relative to cross sections for the 93Nb(n, 2n)92mNb reaction in the 13.64- to 14.80-MeV neutron energy range. Values of 223 ± 7, 233 ± 18, 227 ± 20, 224 ± 18, 232 ± 8, and 236 ±7 mb are obtained, respectively, at neutron energies of 13.64, 13.79, 14.03, 14.33, 14.60, and 14.80 MeV. The neutron energies in these measurements are determined by cross-section ratios for 90Zr(n,2n)89m+gZr and 93Nb(n,2n)92mNb reactions.
