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.

Heat transfer rates to spray droplets under conditions corresponding to those of a loss-of-coolant accident in a light water nuclear reactor have been recalculated in light of the discovery of missing mass exchange terms in the equations of motion used in a previously published computation. While the inclusion of these missing terms into the model equations proves to make only a small difference in the rate of temperature increase of the droplet, the fall distance of the droplets, important in spray heat transfer efficiency, is significantly altered. Furthermore, it is shown that the predicted fall distance, e.g., at 95% temperature interval increase, is very sensitive to the drag law employed in the calculation.
