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 series of fifteen experiments were carried out on an 8 × 30 × 32 in. core in the Pressurized Critical Assembly at KAPL. In twelve of these experiments, 0.030-in. boron stainless steel septa bisected the 8-in. dimension. These septa contained various weight per cent B10. In the remaining three experiments, there were no boron-stainless steel septa in the core. The eigenvalues and neutron density distributions were compared with values which were calculated using Deutsch cross sections and “Thin Region Theory.” The eigenvalues which were calculated were within one per cent of the experimental values, with a spread of approximately one per cent. For all the cores, the calculated eigenvalues were lower than the experimental values. Analyses of the neutron density distributions showed the calculated results in fairly good agreement with the experimental results. In all cases, this agreement was as good for the cores which contained the boron septa as for the ones which did not. It therefore appears that the boron has been well represented by “Thin Region Theory,” and that the main discrepancies between calculated and experimental values are due to the inadequacies of adapting the Deutsch scheme to these cores.
