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.

Thermal-neutron steady-state spectra, in the presence of a 1/E epithermal source of neutrons, calculated in pure and poisoned light water assemblies, using the recent neutron scattering kernel of water suggested by Bansal et al., are found to agree with the recent experimental results of Abbate et al. The effect of different source terms on the steady-state spectra has also been studied.
