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 method for obtaining spherical harmonic or PL solutions of the transport equation from discrete ordinate or SNcodes is developed in this paper. This method depends on a new interpretation of the method as a projection method. The technique of converting SNsolutions into spherical harmonic solutions is discussed in detail for x-y geometry, and numerical results are presented. The method of this paper differs from earlier methods in that SN solutions can be converted to PN-1 solutions.
