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 analysis of critical volumes of aqueous homogeneous solutions of uranium to aid in defining the 2200 m/sec neutron parameters for ENDF/B has been examined. The parameters for 233U and 235U are constrained by relating to the constant K obtained from the analysis of the critical systems. Here K is directly proportional to the hydrogen capture cross section at 2200 m/sec. This Note suggests that the capture cross section of hydrogen be removed from K and that a new constant K/σaH be defined by the critical systems. This new constant is the hydrogen-to-uranium ratio for an infinite critical system populated with neutrons having a Maxwellian energy distribution.
