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.

The PN method is used to solve the multigroup slowing-down problem in plane geometry. A scalar (group-by-group) PN solution that is less limited by computational resources than previously reported vector solutions is developed. The solution is expressed, for a given group, as a combination of homogeneous and particular solutions that satisfies the first N + 1 moments of the corresponding transport equation. An interesting feature of the proposed approach is that the particular PN solution can be written in a form analogous to that of the homogeneous solution, except that a newly introduced class of generalized Chandrasekhar polynomials takes the place of the usual Chandrasekhar polynomials. Numerical results are given for two test problems and compared, for various orders of the approximation, with reference results available in the literature.
