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.

We prove a mathematically rigorous theorem that asserts, under certain carefully stated hypotheses, the validity of the Goertzel and Otsuka conclusions that, in a thermal nuclear reactor that has a minimum critical mass, the fuel must be distributed so that the product of the thermal neutron flux and the adjoint thermal neutron flux is a constant in the core and does not exceed that constant in the reflector. We also furnish some examples that illustrate the necessity of imposing some mathematical hypotheses to obtain the desired conclusions.
