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.

Total gamma-ray attenuation coefficients for five different elements were measured for energies 6.02-, 7.28-, 7.72-, 8.49-, 9.3-, and 9.88-MeV gamma rays. The nuclear resonance scattering method was used in the attenuation of photons for the two energies, 7.28 and 8.49 MeV. For the other energies the direct narrow beam method was used. The total attenuation coefficients were measured with an average uncertainty of 0.6% and appeared to be in better agreement with the tabulated values of Hubbel and Berger than those of Storm and Israel.
