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 beta attenuation method has been developed for measuring void fractions which is sensitive enough for use during local boiling. Comparisons are made with gamma attenuation methods, the effects of preferential void location are demonstrated, and typical void fractions measured during forced-convection, subcooled boiling of water are presented. The technique has been found to be readily applicable to the accurate determination of void fractions during either saturated or subcooled boiling of water and organic liquids.
