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 is developed for obtaining information about reactor power shapes from readings of in-core detectors. The readings are used to determine the coefficients for an expansion of the space-dependent power in terms of a set of basis functions. A least squares approach ensures that all the detector readings contribute to the result. Test cases for one-, two-, and three-dimensional distributions show that accurate results can be obtained with a rather simple choice of basis functions.
