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.

Methods for treating nuclear plus interference elastic scattering of light charged particles in continuous energy or multigroup transport calculations are given. These methods conserve the rate of projectile energy loss and maintain energy balance by ensuring that, on the average, the rate of projectile energy loss equals the rate of target energy gain. It is shown that this approach is equivalent to conserving the P0 and P1 moments of the angular distribution of scattered projectiles and targets in the center-of-mass system. We include an approximate method that corrects for the temperature of the medium. To illustrate the application of these methods to a multigroup problem, we give multigroup data for all 25 projectile/target combinations of protons, deuterons, tritons, 3He ions, and alpha particles based on an example 10-group energy structure. The results are in a compact form from which the group-to-group transfer matrices can be easily calculated.
