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.

A miniature NE-213 scintillation counter and hydrogen proportional counters have been used in conjunction with a calibrated 14-MeV deuterium-tritium neutron source to measure the neutron flux per source neutron per second at a number of positions in a 1.25-m-diam sphere of lithium fluoride. The experimental techniques used are discussed, and the resulting neutron spectra are compared with those from one-dimensional Sn calculations using the ENDF/B-IV data set, allowance being made both for neutron yield anisotropy and for the variation in source neutron energy with angle of emission.
