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.

The MELCOR computer code has been used to simulate the National Research Universal full-length high-temperature 2 (FLHT-2) test. Input data for the analysis were obtained from the FLHT-2 test Data Report and from SCDAP input. Results are presented for the transient liquid level in the test bundle, heat transfer to the bypass flow, cladding and shroud temperatures, and hydrogen generation. Comparisons are made with experimental data and with SCDAP calculations. Several sensitivity calculations with MELCOR, which explore the impact of varying user-input modeling and time-step control parameters on the predicted behavior, were also carried out.
