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.

Cross sections for the 109Ag(n,2n)108mAg reaction are measured using an activation method relative to cross sections for the 93Nb(n, 2n)92mNb reaction in the 13.64- to 14.80-MeV neutron energy range. Values of 223 ± 7, 233 ± 18, 227 ± 20, 224 ± 18, 232 ± 8, and 236 ±7 mb are obtained, respectively, at neutron energies of 13.64, 13.79, 14.03, 14.33, 14.60, and 14.80 MeV. The neutron energies in these measurements are determined by cross-section ratios for 90Zr(n,2n)89m+gZr and 93Nb(n,2n)92mNb reactions.
