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.

The dynamic characteristics of the MSRE were calculated for operation with 235U and 233 U fuels. The analysis included calculation of the transient response for reactivity perturbations, frequency response for reactivity perturbations, stability, and sensitivity to parameter variations. The calculations showed that the system dynamic behavior is satisfactory for both fuel loadings.
