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.

An extensive program of neutronic flux measurements has been carried out during the commissioning of Superphénix. Analysis of the results allowed the comparison of different methods of calculation. The best fit on axial and radial profiles of reaction rates in the core is obtained when control rod reactivity is well reproduced. In the shielding, agreement is improved by the use of experimental correction factors, obtained in clean neutron propagation experiments. A unique feature of the work is the simultaneous analysis of core and shielding experimental results. This feature has a relevant impact on the assessment of appropriate and consistent design calculation routes for liquid-metal fast breeder reactors.
