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.

Empirical expressions are given for the excitation functions of a number of (n, n'), (n, p), and (n, f) reactions useful in the dosimetry of fast neutrons. For fission cross sections, the expressions are fitted to existing evaluations while for activation cross sections, they are fitted to recent experimental data. Average cross sections, derived from these expressions, for various fission neutron spectra are compared with measured values.
