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 results of a systematic qualitative and quantitative study of the little understood phenomenon of fatigue in photomultiplier tubes are presented in this paper. A precision of 0.4% was obtained in the measurements. After having determined the variables that affect fatigue and the mathematical dependence of fatigue with each of them, the general properties of fatigue and the nature and mechanism of the effect are discussed. Photomultiplier fatigue appears as a field emission from the dynode bombardment, probably combined with diffusion or conductivity through the thin insulator film of the dynode surface.
