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.

As part of the Electron Cyclotron Heating (ECH) Facility upgrade at the DIII–D National Fusion Facility, a regulated AC power supply for the filaments of a 110 GHz Gyrotron was designed, tested and integrated into the new ECH power system.1 A precision regulated filament power supply is essential for maintaining the stability of the cathode temperature and consequentially the gyrotron beam current and rf production.2 This paper provides a description of the design of the filament power supply, presentation of test results, and an assessment of its performance.
