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.

A higher order nodal diffusion method is formulated, based on variational principle, Kantorovich’s variational method, and the patch test. In this framework, the relationship between finite element and nodal methods is discussed and the differences are pointed out. General, transverse integrated quasi-one-dimensional nodal equations are derived and matrix representation is given. In addition, a comparison with a similar approach is shown. A numerical solution is carried out using polynomial expansion of the source term and the corresponding analytic solution in alternating directions. Calculations of two-dimensional International Atomic Energy Agency and Biblis benchmark problems are performed and compared with results from the literature. It is shown that the first-order approximation yields the same order of accuracy as the standard nodal methods with quadratic leakage approximation, while the second-order approximation is considerably better.
