Swiss nuclear power and the case for long-term operation
Designed for 40 years but built to last far longer, Switzerland’s nuclear power plants have all entered long-term operation. Yet age alone says little about safety or performance. Through continuous upgrades, strict regulatory oversight, and extensive aging management, the country’s reactors are being prepared for decades of continued operation, in line with international practice.

In current salt-free flow sheets, U(IV) is used as a reductant in reductive partitioning of U-Pu. Because U(IV)-tri-n-butylphosphate (TBP) solvate has a low solubility in the organic phase, quantitative knowledge of U(IV) distribution behavior is important. Published data on U(IV) distribution between an aqueous nitric acid and 30% TBP/n-dodecane biphasic system at 298.15 K is analyzed, and an empirical model is reported. Performance of this model is compared with one earlier published model.
