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.

Resonance integrals for lattices of annular rod absorbers can be accurately determined by ordinary equivalence relation procedures. This is demonstrated for water lattices of annular uranium rods whose inner cylindrical zone is either a void or is water filled. The equivalence cross section, needed to enable the use of tabulated homogenous integrals, is given by a formula recently developed. There are three parameters in the formula that need estimation: a Dancoff factor for the lattice, the probability of neutrons entering the inner rod zone to collide there, and a Bell factor. Ways and means to estimate these parameters are discussed and demonstrated. The interpolation of resonance integrals from entries in existing tables of homogenous integrals is performed with an accurate technique. Results of the equivalence-based calculations are compared with results by the integral transport RABBLE code.
