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 catalyzed exchange reaction between liquid water and hydrogen gas has been studied using a hydrophobic catalyst of platinum deposited on a porous Teflon support. The reaction was studied with a new method in which a mixture of water mists and hydrogen gas moves downward through the catalyst bed co-currently. This new method was employed to improve the poor contact efficiency between liquid water and hydrogen gas in the hydrophobic catalyst bed. It was found that the reaction rate increased an order of magnitude over the conventional method in which liquid water and hydrogen gas react countercurrently. These experimental results have been analyzed in terms of a rate determining step and compared with previous ones.
