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.

Measurements were made of the viscosity of Columbia River basalt and basalt-urania melts containing up to 18 wt% UO2 in the temperature range 1360 to 1960°C. A concentric cylinder-type viscometer was used. The combined data were fit by the equation, where η is viscosity in poise, T is temperature in degrees Kelvin, and X is the weight percent UO2 in the melt.
