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.

Molten glass interacts explosively with water under certain contact mode conditions. The contact mode found explosive is as follows: Molten glass enters the water bath in the film boiling regime (as predicted by Dhir's correlation), and soon after entry the vapor film is perturbed sufficiently by an external pressure pulse. The ensuing reaction proceeds basically along the same lines as energetic tin/water interactions observed by several investigators. In the absence of this pressure pulse, the event is nonenergetic. The present findings are for a combination in which the hot material has a very low thermal diffusivity and the calculated interface temperature is significantly (∼180 K) below its melting temperature. This is similar to the characteristics of the UO2/sodium or UO2/water combinations. The observed explosive glass/water interactions show growth times on the order of a few milliseconds. The particulate size distribution from the present tests was coarser than the particulate size distribution from some in-pile and out-of-pile UO2/sodium interaction tests.
