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.

Three neutron transport problems involving two different media are solved in two-group theory for isotropic scattering based on the singular-eigenfunction-expansion solution of the transport equation. This work has two purposes: First, it is shown that two-media problems in two-group theory can be reduced to regular computational forms using the half-range orthogonality theorem; second, in support of benchmark activities, three model problems are defined, and their solutions are reported based on an exact theory.
