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 diffusion coefficients of D2 in Nb—1 wt% Zr were determined in the range from 923 to 1148 K. A hollow-cylinder model, used as the frame of reference, adequately described the transport of D2 through the alloy containing oxygen impurities. The diffusion coefficient is temperature dependent and is best described byD (m2/s) =8.5 ± 7 × 10−8 exp (−48.2 ± 6.7 × 103/RT) .
