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 vibration and impacting of an instrument tube in a boiling water reactor (BWR) have been studied using a one-dimensional bimodal model. Four modal nonlinear boundary conditions have been applied, and a set of coupled nonlinear equations describing the temporal evolution of two continuous modal amplitudes have been obtained. These equations have been numerically solved by means of a generalized Runge-Kutta algorithm for stochastic equations. The theoretical results have been compared with experimental in-core neutron noise measurements performed in a 1300-MW BWR, Gundremmingen C, and have been used to interpret the particular vibration behavior of one instrument tube.
