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 dynamic behavior of the Superphénix core was tested during commissioning of the plant. From comparison of experimental and calculated results, it was concluded that the time-dependent parameters agree quite well. The comparison is based on DYN system code calculations and on tests performed at zero power (reactivity step leading to a self-stabilization) and at power (steps on reactivity, primary flow, and secondary flow). These tests checked the behavior of the nuclear steam supply system.
