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.

The relative power distribution in the TSF-SNAP reactor was determined by scanning individual fuel elements for fission-product gamma rays, and the absolute fission rate was determined from uranium-foil activation. Numerical integration of the fission density over the core volume gave an absolute power calibration for detectors and foils external to the core. Calculations of both the axial and radial power distributions by Monte Carlo and discrete ordinates methods were in excellent agreement with the measured distributions.
