In the U.S., lack of a permanent, deep geological repository for spent nuclear fuel has long put a brake on expanding the industry. Political sentiment may be changing. This spring, surprisingly, more than a dozen U.S. legislators proposed measures to restart licensing for the Yucca Mountain nuclear waste repository in Nevada, touted since 1987 as the country’s leading storage site. Meanwhile Senator Lisa Murkowski of Alaska is advocating for very small, modular reactors being developed at Idaho National Laboratory. (Rosatom is making small reactors, too.) And a group of Western states has entered a tentative deal with NuScale Power in Oregon for a dozen of its modular reactors. Improved fuels and growth in small reactors could be a big part of a nuclear power rebirth.
