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 influence of burnable gadolinia poison in fuel assemblies on coolant void reactivity for a pressure-tube-type boiling light-water-cooled heavy water reactor is investigated in critical experiments using the Deuterium Critical Assembly (DCA) and theoretical analyses by the WIMS-D4/ CITATION code system. The experimental and the calculated void reactivities agree within ±0.2 $., A number of gadolinia-poisoned fuel assemblies are dispersively loaded in the central region of the DCA core together with unpoisoned fuel assemblies. Each gadolinia-poisoned assembly is composed of three or four Gd2O3-poisoned UO2fuel rods as well as unpoisoned fuel rods. The gadolinia concentration is varied from 0.0 to 1.0 wt%., The void reactivity in the core becomes less negative with the addition of gadolinia but become saturated at a Gd2O3 concentration of ≈0.5 wt%. The void reactivity becomes much less negative with a higher loading ratio of the gadolinia-poisoned assemblies in the core and as the gadolinia-poisoned fuel rods are arranged in the outer layers of the assembly. When the fissile nuclide in the pellets of the unpoisoned fuel assembly is changed from uranium to plutonium, the incremental positive shift of the void reactivity can be reduced because of the increase in the 0.3-eV thermal resonance absorption of 239Pu and 241 Pu.
