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.

In fusion reactor systems, the reaction rates are calculated from a velocity-space integral over the reaction cross section times the distribution functions of the reacting species. In a plasma, the shape of the distribution functions themselves is determined by solving a diffusion-plus-convection problem in velocity space. This review briefly describes the physical processes of central interest to such a description and the mathematical formulation of the problem. It presents the numerical methods used in such calculations by various authors. Optimization on a vector computer (Texas Instruments ASC) is described. Finally, some indication is given as to what may be expected as reactor systems are treated in more detail.
