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 minicomputer-based system for reactor surveillance was developed and demonstrated on-line. The state of the reactor is characterized by the system from an analysis of noise signals, and a surveillance algorithm statistically describes normal behavior from this characterization. Hyperellipsoids are constructed from this description to enclose normal regions of behavior in the multidimensional measurement space, which represents all possible reactor states. When measurements outside normal regions are detected, the status of the reactor is suspect. Tests at the High Flux Isotope Reactor demonstrate that the algorithm can sense changes in reactor conditions that the plant instrumentation cannot detect.
