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 procedure, described previously, for the preparation of high purity beryllium hydroxide has been improved and demonstrated on a kilogram scale, and a systematic study of its chemistry has been carried out. The Be(OH)2·xH2O starting material is dissolved in acetylacetone (HX) as BeX2, scrubbed with aqueous EDTA to remove metallic impurities, stripped with nitric acid, and precipitated with ammonia. The dried Be(OH)2 · 0.3 H2O, a granular, free-flowing powder, was obtained in 85% yield. Detectable metallic impurities totalled <5 parts/106. The variation of BeX+ and BeX2 formation quotients with ionic strength as well as the variation of BeX2 and HX distribution coefficients with both aqueous ionic strength and organic phase composition are summarized. Decontamination efficiencies for some 13 cations were estimated to be very high. Effective purification was demonstrated on a sample of Be(OH)2 starting material which was contaminated with 1000 parts/106 parts BeO of Na+, Mg2+, B(III), Cu2+, Al3+, Fe3+ and Cr3+.
