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.

Using the Markovian description of stochastic processes, the fluctuations in pressurized water reactor cores (for example, temperature and bubble population fluctuations) are modeled. The model includes one-dimensional space and time dependence. Fluctuations are described with the help of a single stochastic variable N(z, t). Generally this approach is not satisfactory in practical problems, but in this way spatial effects can be investigated by a simple model. For this case, connections between moments of N(z, t) are derived. These moments are calculated both for transient and steady-state processes. Introducing spectral density functions in frequency and wave-number domains, a condition is given for the validity of the point model approach.
