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 new radiotracer technique for determining wear rates of selected automotive engine parts is described and demonstrated for piston rings. The technique uses Fe55 instead of Fe59 as the radiotracer. A liquid scintillation method for counting Fe55 is necessary since it decays by electron capture and emits only the Mn characteristic X-ray of 5.9 keV. A simple method for extracting the wear particles from the engine oil and getting the iron into the liquid scintillation mixture is described. Counting yields of 8 to 9% are obtained by the method. The Fe55 technique of wear measurement does not directly compete with the existing Fe59 technique since slightly lower sensitivity and longer sample preparation is required. However, the much longer half-life (2.6 years as compared to 45 days) and the lower radiation energy (5.9 keV as compared to over 1 MeV) allows the Fe55 technique to be used for long-term wear studies, for double tracer studies, and for studies of large engine parts.
