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.

Employing an extended Kalman filter, on-line estimates of gas gap conductance in a pressurized water reactor (PWR) fuel pin are obtained. A seventh-order, nonlinear model of a PWR is described. Implementing this model in the Kalman filter allows estimation of the reactor state vector, which includes gap conductance as an element. Using data from a test reactor facility, estimator performance is evaluated.
