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.

In this paper, transport theory methods have been used to obtain a modified form of the PN approximation. This modification involves use of the exact asymptotic roots instead of the PN roots, resulting in a corresponding change in the Marshak free surface boundary conditions. Various numerical examples of this transport theoretic PN approximation have been given.
