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.

Heat of transports Q* of hydrogen isotopes in the α-phase of Zr have been measured in temperature regions from 623K to 673K for H and from 523K to 623K for T by analysing the redistribution process under a thermal gradient. An isotope mass dependence of Q* has not been unequivocally established though a tendency that Q*(H)>Q*(T) has been observed. These data have been discussed on the basis of the biased-jump diffusion model, and a large negative bias effect has been pointed out as characteristics of Q* of hydrogen isotopes in group-IV metals in comparison with the case of group-V metals.
