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.

The application of the finite element method to problems in neutron diffusion in space, energy, and time is studied. The use of piecewise polynomials with a variational form of the diffusion equation leads to algebraic systems of equations with characteristics similar to the usual finite difference equations. In Part I, a theoretical analysis of the finite element method, with Hermite polynomials, is presented and rigorous error bounds for the approximate solution are developed. In Part II, numerical studies are presented for problems in space and time. The results confirm the theoretical analysis and indicate the power of the method for diffusion problems.
