EPA administrator Lee Zeldin talks the future of nuclear
In a recent interview on New York radio station 77 WABC, administrator of the Environmental Protection Agency Lee Zeldin talked with host John Catsimatidis about the near-term future of the domestic nuclear industry and the role the EPA will play in the sector.
Catsimatidis kicked off the interview by asking if the U.S. will be able to reach total energy independence. Zeldin responded by saying that decreasing energy dependence on other countries, especially adversaries, was a top priority for him and the Trump administration.

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.
