Proposed legislation in California could exempt certain reactor designs from the state’s long-standing moratorium on new nuclear generation, effectively ending the moratorium.

California Assembly Member Lisa Calderon (D., 56th Dist.) filed A.B. 2647 with the California State Assembly last week.

If the bill progresses and becomes state law, it could pave the way to increasing the number of nuclear reactors in the state in the future. Currently, Diablo Canyon nuclear power plant houses the only operational commercial nuclear reactors in California.

Illinois Gov. J. B. Pritzker issued a new executive order (EO) on February 18 directing both the Illinois Power Agency and the Illinois Commerce Commission to issue a notice of intent (NOI) to potential developers of new nuclear power plants.

The signing of that EO took place on the same day Pritzker delivered his 2026 State of the State address, in which he set a goal of building at least 2 gigawatts of new nuclear capacity in the state.

New power reactors of any size can be now be sited in the state of Illinois, thanks to legislation signed by Gov. J. B. Pritzker on January 8. The Clean and Reliable Grid Affordability Act (CRGA)—which Pritzker says is designed to lower energy costs for consumers, drive the development of new energy resources in the state, and strengthen the grid—lifts the moratorium on new, large nuclear reactors that Illinois enacted in the late 1980s.

The recent surge in positive sentiment about nuclear as the most viable answer to global energy needs and decarbonization goals has found governments around the world taking steps to reverse course on decades-old bans, moratoriums, and restrictions on new nuclear development.

It’s been almost 35 years since Illinois last added a nuclear power reactor to the grid (Braidwood-2, a pressurized water reactor operated by Constellation, reached commercial operation in October 1988). And it’s been 63 years since a research reactor reached initial criticality at the University of Illinois–Urbana-Champaign (UIUC). The university’s TRIGA Mark II started up in August 1960 and was shut down in 1998. For about 25 years, UIUC—the flagship public university in a state that generates more power from nuclear energy than any other—has lacked an operating research reactor.

Consolidated Uranium plans to acquire Virginia Energy Resources, which owns Virginia Uranium and the Coles Hill Uranium Project, an undeveloped uranium deposit that sits under about 3,000 acres of land in south central Virginia. The state’s General Assembly has maintained a moratorium on uranium mining since 1982 that was upheld in the courts as recently as 2020, but Consolidated Uranium sees reason for “confidence that the moratorium on developing uranium projects in the state may ultimately be overcome,” and appears content to settle in for a wait.
