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.

This technical note models the concept of fuzziness along with the stochastic behavior of the point-kinetics neutron equation. The fuzzy stochastic model is investigated numerically by extending the Euler-Maruyama method to fuzzy form. The uncertain neutron density and delayed neutron population are obtained and compared with Monte Carlo and stochastic principal component analysis solutions. Various combinations of fuzzy parameters are considered, and the uncertain neutron density and delayed neutron population are obtained in different cases. Finally, the sensitivity of these fuzzy parameters with stochastic behavior is investigated.
