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.

Numerical calculations performed on the ORACLE have made possible exact inclusion of the effect of Doppler broadening of resonance lines in the calculation of resonance absorption integrals. The effective resonance integrals of U238 and Th232 have been calculated as functions of the scattering cross section per absorbing nucleus for 0° and 300°K. Agreement of the calculated (300°K) and experimental resonance integrals is excellent for U238 and good for Th232, except in the case of pure ThO2 where a discrepancy is noted.
