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.

Based on a self-adjoint form of the one-group neutron transport equation, the finite element method is applied to the computation of the critical halfthickness of a bare slab. Different optional schemes are compared numerically. For a given order of approximation it is shown that accuracy can be improved appreciably by a proper implementation of the nonreentrant boundary condition and by using a varying element size.
