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.

Improvements have been made to an existing method for implementing realistic pairing corrections in particle-hole state densities. The threshold energy for the pairing “single particle” states is used to replace the usual equispacing model Pauli energy, resulting in an improvement in the calculated state densities for low exciton numbers. Remaining discrepancies between the simple state densities and the results of a detailed pairing calculation are attributable to deficiencies in the original equispacing model state density formula. An ad hoc improvment to this formula is proposed. The method is extended to state densities for two types of fermions, and questions associated with its practical implementation are discussed.
