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.

Equations are derived to determine the optimum design parameters (minimum error) for the gamma-ray one-shot-collimator method of measuring average void fractions in two-phase flow. A compromise is indicated between the desirability of response linearity cm the one hand and maximum sensitivity on the other. Results from a prototype gauge using the 60-keV gamma rays from 241Am are given for void fractions of extreme distributions within a circular channel and are compared to a previous gauge that used a 170 Tm source.
