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.

Neutron density and importance distributions, βeff/Λ and moderator temperature coefficients have been experimentally studied in connection with a central water gap of a light-water reactor having a water to UO2 volume ratio of 1.5. Thermal importance functions are determined from the reactivity weighting function, while the fast importance functions are measured by a 252Cf source introduction method. Values of βeff/Λ measured by pulsed-neutron experiments decrease from 202 sec−1 in the uniform core to 185 sec−1- for the core with a water gap of 6.7 cm effective radius. It is also shown that the water gap influences the moderator temperature coefficient to a considerable extent.
