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.

Transport parameters (migration area, age to indium resonance) of fast neutrons from a plutonium -beryllium source have been measured in aqueous absorbing solutions at several temperatures (35, 40, 55, and 75°C), using boric acid as the 1/ absorber. For the measurements at 35 and 40°C, the saturation concentrations of boric acid were attained at 70 and 80 g/liter, respectively. For a 1/ absorber, a temperature-dependent power series representation of k2 in terms of absorption cross section ∑ao was proposed, based on the concept of neutron temperature. The temperature range wherein such an expansion remains valid was experimentally determined. It was found that strong concentrations of a 1/ absorber caused much difficulty in experimentally resolving the thermal neutron spatial distributions, an observation which might have a direct relation to the (∑t)min limit of Corngold.
