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 complete inverse mass expansion is derived for the difference-differential equation describing neutron moderation in infinite homogeneous media, far energetically from the sources. We consider slowing down equations with different values of the nucleus-to-neutron mass ratio, and a common value of the capture-to-scattering cross-section ratio. The latter is assumed to be an analytic function of lethargy. A preliminary analysis suggests the functional form of the leading term of the expansion. Further treatment leads to a first-order, linear, inhomogeneous, ordinary differential equation satisfied by the expansion terms. Different terms of the expansion correspond to different free terms of the differential equation. Imposing a normalization condition, the solution of the differential equation is made unique, and a formal, practically effective solution to the general asymptotic moderation problem is obtained.
