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.

A method of calculating resonance absorption in a rod in a two-region circularized cell is developed. The method uses space-and lethargy-dependent neutron sources and, thus, includes overlapping and interference effects. An energy range of interest is divided into extremely narrow intervals of equal lethargy width. For each interval, the source distribution in each region is taken to be a three-term polynomial. By using this form for the source and the assumption that neutrons enter the rod isotropically, we obtain the reaction rates and the flux distribution for the interval. The reaction rates are used to obtain resonance integrals; the flux distribution is used to get the source distribution for lower energies. Calculations of the errors introduced into the resonance integral of the two closely spaced 232Th resonances by the assumption of flat sources are given, as well as calculations of the effects of interference in UO2-ThO2 mixtures, which lie within the errors of the experimental results obtained by Foell.
