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 results from the BETA molten core/concrete interaction (MCCI) experiments conducted at Kernforschungszentrum Karlsruhe (KfK) and the associated analyses using computer models developed by KfK and by Sandia National Laboratories, i.e., WECHSL and CORCON, are described. Two important observations were made in the BETA steady-state tests: The first observation could be modeled by WECHSL and CORCON by modifications when interface heat transfer considered a “transition boiling” analogy model. The second observation was not modeled but is expected to be important during the high-temperature phase of the MCCI when fission product release is of concern. These results suggest that the BETA experiments provide necessary information to validate MCCI models for silicate (basaltic) concrete. For limestone (carbonatic) concrete, there are still open questions that further tests must address.
