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.

For one-speed neutrons, we have investigated the effect of anisotropy in the scattering kernel on their angular distribution at various space points inside slabs of different thicknesses. This has been done by solving the one-speed space-angle-dependent neutron transport equation for a pulsed source, by numerically iterating over the space and angle variables. We find that the fundamental decay constant decreases with increasing anisotropy, the effect being more in thicker slabs. The effect of scattering anisotropy on the angular flux inside slabs, as well as on leakage flux, has been reported. For a specific scattering kernel, the variation of angular flux with thickness of the slab is also discussed. Some of these results have been compared with those based on P1 and P3 approximations.
