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 simple, physically transparent method is developed to calculate the electric charge per neutron captured in prompt response self-powered neutron detectors (SPNDs), which contributes to the emitter-collector current. This charge is written as the energy integral of the product of two functions: the spectral function S(E), which is the energy spectrum of all electrons resulting from prompt gamma interactions with the atoms of the emitter, and the electron spectral contribution ∈ f(E), which is the probability that an electron released with energy E reaches the collector. The function ∈ f(E) is given an analytical approximate expression derived from an analytical approximation obtained for the path length probability distribution function. The exact expression of ∈ f(E) is also obtained analytically for infinitely long emitters in terms of special functions. The method allowed the creation of an extremely fast algorithm to calculate the effective charge and was applied to cobalt prompt response SPNDs.
