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.

Previous calculations and measurements of the age of fission neutrons in water are tabulated with special emphasis on those aspects of the experiments which may require corrections or lead to errors. A plane-source geometry is described and data taken in this geometry are interpreted in terms of these corrections. The measured second moments of the distributions from 18, 24, and 30 in. sources are corrected for foil and source plate mass effects. A geometric correction is then applied to obtain the age of fission neutrons in water as 27.86 ± 0.10 cm2.
