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.

A theoretical model was developed to predict the amount of nucleation that occurs as a result of neutron interactions in superheated liquids. The model utilizes nuclear cross-section data, charged-particle linear energy transfer information, and computations of critical bubble nucleation energy to generate the number of bubbles formed in superheated liquid droplet (“bubble”) neutron detectors exposed to neutron fluxes of specified intensity and energy. Previous experimental attempts to relate effective (energy-depositing) ion track length L to critical bubble radius rc using a dimension-less coefficient were unsuccessful. The formulation of a new coefficient b, equal to the ratio of effective ion track length L to the seed bubble radius ro is now proposed. By parameterizing the value of b within the model, the least-squares best value of b was determined to be 4.3 for both high- and low-energy 252Cf neutrons. Thus, the effective recoil ion track length in radiation-induced nucleation can be determined if the seed bubble radius is known.
