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.

The stability of Pu(IV) polymer suspensions, the solubility of the polymer, and the nature of the soluble plutonium species were studied from pH 3 to 7 in dilute chloride and in dilute nitrate solutions. Polymer suspensions are not stable at pH values above 5, and hence the polymer is not expected to be mobile in the lithosphere. The solubility of polymer is intermediate between the solubilities of Pu(OH)4(a) and PuO2(c) and it is <10 ppb in air-equilibrated dilute salt solutions at pH 7. The soluble plutonium is present as plutonyl species.
