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.

An improved response matrix method has been proposed to effectively take into account the anisotropy of neutron angular distributions. The method utilizes a relation between the P0 and P1 components of a neutron angular distribution instead of calculating them independently. Hence the number of unknowns as well as computing time can be kept about the same as in the conventional response matrix method which adopts an isotropic approximation of a neutron angular distribution. The proposed method has been evaluated by applying it to one-dimensional slab and two-dimensional hexagonal systems. The results are quite promising: In comparison with the reference SN calculation, the difference of the neutron multiplication factor and power distribution is within 0.1% Δk/k and 2%, respectively, and furthermore, the computing time is reduced to below one-third.
