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 postirradiation fatigue-crack propagation behavior of solution-annealed Type-304 and 20% cold-worked Type-316 stainless steels irradiated to a fluence of 1.3 × 1021 n/cm2 (E >0.1 MeV) at temperatures of ∼851 and 891°F (455 and 477°C) was characterized using linear elastic fracture mechanics techniques. Irradiation to this fluence had little or no effect on the crack growth behavior of both materials at test temperatures of 800 and 1000°F (427 and 538°C).
