DOE fast tracks test reactor projects: What to know
The Department of Energy today unveiled 10 companies racing to bring test reactors online by next year to meet Trump's deadline of next Independance Day, leveraging a new DOE pathway that allows reactor authorization outside national labs. As first outlined in one of the four executive orders on nuclear energy released by President Trump on May 23 and in the request for applications for the Reactor Pilot Program released June 18, the companies must use their own money and sites—and DOE authorization—to get reactors operating. What they won’t need is a Nuclear Regulatory Commission license.

The matching of D-T fusion breeders to heavy-water CANDU-type reactors has been studied using the transport code ANISN to evaluate the neutron transport and breeding characteristics of a low-power-gain fusion blanket. The fusion blanket consists of a niobium structure, natural lithium coolant, and a graphite reflector with 2- to 6-cm-thick zones of Th, ThO2, or ThC situated between the first wall and the reflector. Total breeding ratios of 1.40 to 1.50 have been calculated. Using the calculated breeding ratios, a system period of less than 10 years is determined for proposed solid thorium fuels. The reaction rate ratio of fusion to fission is less than unity.
