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.

The transverse diffusion coefficient is calculated by integrating the current derived from heterogeneous multigroup dipole theory in a finite, square system, along two opposite sides of the square cell. Use of response coefficients allows the result to be presented in relatively simple form, regardless of fuel element complexity. Subsequently, the buckling dependence is eliminated from the diffusion coefficient, or reduced to lowest order, making it consistent with the low order approximation represented by dipole theory. Results are compared with other methods and a numerical example is given.
