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 accident at Three Mile Island Unit 2 left the reactor core in a severely degraded condition. Core removal methods and equipment designed for an undamaged reactor refueling required extensive modification. Fuel debris containments, tooling, contamination control, and water processing methods were tailored to known and postulated core conditions using primarily manual rather than robotic methods. Flexibility was a key element in the equipment design since little definitive data on reactor physical conditions were available.
