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.

Fatigue crack propagation rates at 24, 427, and 593°C were not affected by specimen thickness within the range 7.6 to 25.4 mm. Also, singleedge-notch cantilever and compact tension specimens gave comparable crack growth rates for a given stress intensity factor range. Crack growth behavior was analyzed with respect to fracture mechanics criteria.
