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.

To improve the integrity of the liquid-metal fast breeder reactor steam generators, a concentric protective barrier, known as a protector tube, has been introduced around each bayoneted heat transfer tube. In the event of a water-to-sodium leak, this protector tube is expected to contain the sodium-water reaction effects resulting from medium to large leak rates and, for small leaks, to retard damage propagation to adjacent heat transfer tubes prior to leak detection, and thus allow sufficient time for an orderly shutdown of the steam generator. The proof-of-principle tests reported in this paper have demonstrated the advantages of the protector tube concept.
