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.

Differential cross sections are reported for elastic and inelastic scattering of neutrons from beryllium. Source neutrons were provided by the D(d,n)3 He reaction at energies from 7 to 15 MeV in 1-MeV steps. Scattered neutrons were observed over a flight path of 4 m at angles ranging from 25 to 160 deg in 5-deg increments. The integrated elastic scattering cross sections agree well with the ENDF/BIV cross-section set. The inelastic scattering cross sections are for the sum of the 1.69-, 2.43-, 2.8-, and 3.06-MeV-state cross sections and fall below the ENDF/B-IV predictions. Inelastic scattering to the 2.43-MeV state in 9Be accounts for less than half of the total 9Be(n,2n) cross sections above 8 MeV.
