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.

An instrumented absorber experiment in the Experimental Breeder Reactor-II yielded data on the helium release of boron carbide at exposures up to 53 × 1020 neutron captures/cm3 and temperatures from 766 to 952°C. Helium release results demonstrated a high rate of helium release initially, and a much lower rate at higher burnup levels. In addition, the experiment demonstrated the effectiveness of vents in releasing gas from a plenum during irradiation.
