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.

Measurements have been made of the fast neutron cross sections for the production of N16 and N17 in the uranium rod cooling water of the NRX reactor by the reactions O16(np)N16 and O17(np)N17. The N16 and N17 were detected by their gamma and fast neutron activities, respectively, in a continuously flowing sample of the effluent water from a uranium rod. The cross sections (fission neutron spectrum) for the reactions O16(np)N16 and O17(np)N17 are 1.85 ± 0.15×10-2 millibarns and 9.3 ± 0.9×10-3 millibarns, respectively.
