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.

Monte Carlo calculations for monoenergetic x rays (70 to 200 keV) normally incident on soil have been performed to determine changes in the reflected radiation due to material perturbations at depths of 1 and 1.6 mean-free-paths. The accuracy of the calculations was achieved using a scheme of correlated sampling in which a “complete correlation” is maintained in the sense that identical sampled event sequences are used for the perturbed and unperturbed problem. A somewhat general discussion of correlated sampling is included with emphasis on the mathematical reasons for employing the method. It is shown for a special case that a naive use of correlated sampling may lead to results drastically inferior to those obtained by independent sampling. The Monte Carlo calculations are compared with two-dimensional discrete ordinates results and agreement is very good. Output quantities are reported in terms of energy-dependent fluence and current. The calculated results demonstrate the feasibility of the approach to albedo sensitivity problems in general.
