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.

Some theoretical calculations concerning the diffusion of thermal neutrons (2.5 × 10−4 to 0.7 eV) across an absorption discontinuity in water assemblies consisting of pure water on one side and the water solutions of boron (a 1/v absorber) having different concentrations on the other side have been performed by solving the Boltzmann transport equation in the diffusion approximation using the multigroup formalism. The Nelkin scattering kernel of water at 293 K has been tried in the present case. At the boundary, the equilibrium neutron distribution is disturbed and is reestablished to the equilibrium distribution of the second medium within a few centimetres from the boundary. The diffusion lengths so obtained show a good agreement with the experimental results of Martinho and Costa Paiva.
