ANS Winter Conference: DOE, NRC leaders stress need for speedier nuclear approval
David Wright
Chris Wright
During speeches at the American Nuclear Society’s Winter Conference & Expo, happening this week in Washington, D.C., Energy Secretary Chris Wright and Nuclear Regulatory Commission Chair David Wright both promised that the Trump administration will speed up nuclear reviews so the U.S. can maintain leadership in nuclear energy.
The DOE’s Wright took a stab at the NRC’s traditionally slow bureaucratic processes in approving primarily large light water reactors in the past, saying that the agency needs to speed up to meet the greater demand for new small modular reactors.
