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 partial differential equations describing thermal processes in the reactor core are solved with respect to the coolant temperature in two cases: (1) when the fuel element temperature is averaged over the fuel element cross sectional area, (2) when the temperature distribution in this cross section is taken into account. It is assumed that the fuel element is of the rod type, there is no conduction in the longitudinal direction, and the inlet coolant temperature is a constant. The results obtained as solutions of these equations are discussed from the point of view of the application of an analogue computer to the exact simulation of thermal processes in the reactor core.
