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 modified truncated singular value decomposition (MTSVD) is employed to unfold proton recoil pulse-height spectra into neutron energy spectra, using experimentally measured response functions. To illustrate the method, spectra from 252Cf and 239PuBe sources are unfolded. The relative error, defined in terms of the 1-norm, using the MTSVD method is found to be approximately half that of the truncated singular value decomposition for the 252Cf spectra. Relative errors for the 239PuBe spectra were approximately equal for the two methods. The method is limited by the precision of the measurement of the response functions and the pulse-height spectra. More precise measurements would allow the use of larger truncation parameters and are likely to result in more accurate reconstructed neutron spectra. The MTSVD method is particularly suited to real-time on-line unfolding of spectra.
