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.

A simple yet powerful method is developed to calculate steady-state creep rates in a nonvolume conservative plastic deformation that is linear in the applied stress. The method is applicable to complex stress distributions that exist in many nuclear reactor core components. Application of the method leads immediately to the steady-state creep rates for bending in plane stress and plane strain for a swelling rate that depends on position only through variation in the hydrostatic stress. The bending rate in plane strain can be significantly lower than the corresponding rate in plane stress. The method accommodates arbitrarily spatially varying stress-free swelling rates with only minor generalization. For example, the steady-state stress distribution induced by non-uniform swelling through a tube wall is obtained simply by application of standard formulas for thermal stresses in this geometry.
