Powering the future: How the DOE is fueling nuclear fuel cycle research and development
As global interest in nuclear energy surges, the United States must remain at the forefront of research and development to ensure national energy security, advance nuclear technologies, and promote international cooperation on safety and nonproliferation. A crucial step in achieving this is analyzing how funding and resources are allocated to better understand how to direct future research and development. The Department of Energy has spearheaded this effort by funding hundreds of research projects across the country through the Nuclear Energy University Program (NEUP). This initiative has empowered dozens of universities to collaborate toward a nuclear-friendly future.

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.
