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 title problem is considered from the viewpoint of one involved in aerodynamics problems, rather than reactor modeling. The status of opinion is briefly reviewed on two sources of error: errors due to discretization, especially in regard to “high cell Reynolds number” difficulties, and errors in the continuum equations, especially in regard to turbulence modeling. It is concluded that significant improvement is to be expected over the lumped-parameter codes, but that even the forthcoming codes based on simulation of the partial differential equations are expected to be limited to a rather crude level of accuracy.
