New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

Because of the demand for intense neutron beams for applications in basic and applied sciences, several design concepts have appeared in the literature recently. It is, therefore, appropriate to present a theory that connects the large variety of possible designs in order to individualize the main parameters from the neutronic point of view; the theory is validated with results from numerical analysis that simulate the transport of neutrons in such drastically different systems as spallation and fission sources. The theory is used to present scoping studies for the production of thermal neutron fluxes around and beyond 1020/m2·s.
