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 role of impurity content in the irradiation of alumina has been investigated. The extra helium production from the impurities contributes only 2% or less of the helium production from pure alumina. It is concluded that the lower swelling indicative of higher purity alumina is probably due to its smaller grain size rather than a mechanism associated with the impurities per se.
