Advisers back Long Mott permit, Navy picks Radiant for Crane microreactor
The NRC's Advisory Committee on Reactor Safeguards said on October 16, 2026 that its review supports a construction permit for Long Mott, a four-unit Xe-100 plant at Dow's Texas site, while listing fuel and source-term work for the operating license. The Navy picked Radiant on October 20 for a prototype microreactor at Naval Weapons Station Crane, Deep Fission signed a Kansas purchase agreement with no minimum purchase, Westinghouse announced an approximately $1 billion LEU+ fuel factory, and an IAEA mission found the UAE's response to a May drone strike at Barakah effective.
The Nuclear Company proposes up to six AP1000s on Kentucky's Ohio River
The Nuclear Company proposed Prosperity One on October 21, 2026: up to six Westinghouse AP1000 reactors, about 6.6 GW, at Carrs Bottom in Lewis County, Kentucky, starting with two units. It holds a land option but has filed no NRC or PJM application and announced no power buyer or federal financing.
Tianwan 7 reaches the grid, Mochovce 4 waits, Poland orders AP1000 parts
Tianwan 7, a VVER-1200 in Jiangsu, sent its first power to China's grid on October 8, 2026, CNNC said; Slovakia's Mochovce 4 missed its October 13 grid connection while part of its technical tests is repeated. Poland's PEJ told Westinghouse to start ordering six long-lead nuclear-island components for its first AP1000, Westinghouse placed conditional module orders with four Polish suppliers, and PEJ and PGE split work on a second plant.
NRC renews AP1000 design certification with Vogtle-based Revision 20
The NRC published a direct final rule on October 14, 2026 renewing Westinghouse's AP1000 design certification and incorporating design control document Revision 20, which reflects changes made in licensing, building and operating Vogtle Units 3 and 4. It takes effect December 28, 2026 unless significant adverse comments arrive by November 13.
US and Korea earmark up to $120B for eight reactors, with no sites named
South Korea and the United States announced Project Power on September 30, 2026, a framework to build six Westinghouse AP1000 and two APR1400 reactors in the US with $120 billion of Korea's $200 billion investment ceiling, including $20 billion of contingency, and agreed to cooperate on a $10 billion advance payment by year-end aimed at long-lead items. No specific sites, owners or power buyers are named; Westinghouse's shareholders call the terms non-binding, Brookfield cites a 5% to 10% Korean stake in Westinghouse, and Cameco puts the APR1400 waiver at about $2 billion of value per reactor.
Westinghouse eVinci reaches zero-power criticality at 663°C
Westinghouse said on September 15, 2026 that its eVinci microreactor test reached zero-power criticality at 663°C on September 3 at the National Criticality Experiments Research Center in Nevada, and that researchers made a subcritical reactivity measurement at a peak core temperature of 1,011°C, which the company calls a record high temperature for a reactivity measurement at NCERC. The run follows the August 24 zero-power criticality at the same facility.
