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.

Experimental and theoretical studies have been performed to characterize the behavior of airborne particulates (aerosols) expected to be produced by hypothetical core disruptive accidents (HCDAs) in liquid-metal fast breeder reactors (LMFBRs). These aerosol studies include work on aerosol transport in a 20-m-high, 850-m3 closed vessel at moderate concentrations; aerosol transport in a small vessel under conditions of high concentration (∼1 kg/m3), high turbulence, and high temperature (∼2000°C); and aerosol transport through various leak paths. These studies have shown that little, if any, airborne debris from LMFBR HCDAs would reach the atmosphere exterior to an intact reactor containment building.
