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.

A method for estimating the average void fraction in water-moderated power reactors is presented. The method might be useful to determine departure from normal boiling conditions or nucleate boiling in boiling and pressurized water reactors, respectively. A standing acoustic wave is introduced in the core and the neutron density is measured, squared, time-averaged, and compared with the same quantity without an acoustic wave. The ratio is inversely proportional to the sixth power of the acoustic velocity; and the acoustic velocity depends on the average void fraction in the core. Consequently, this ratio is very sensitive to the average void fraction in the core.
