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 fatigue crack growth-rate behavior of Zircaloy-2 was determined at room temperature for three material conditions: annealed, hydrided annealed, and 35% cold-worked. The crack growth behavior was found to obey the “power law” of crack propagation. Usage of the data is discussed, and a hypothetical example for estimating the fatigue life of a flawed component is given.
