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.

In recent years there has been an increased interest in advanced reactors in the United States. Several concepts are being proposed by multiple vendors and start-ups, with an accelerated pathway to market. In particular, DOE has recently issued two awards aimed at deploying demonstration reactors and several more aimed at accelerating current research activities. An important activity related to commercialization of these concepts is licensing and the overall role of the regulator. Furthermore, central to licensing and safety analysis is the understanding of thermal-hydraulics phenomena, which present considerable differences compared to light-water reactors. In this panel we will address current thermal-hydraulic issues in the licensing of advanced reactor concepts and ongoing research on this topic.
