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.

This research presents a discrete element method (DEM) model for simulating the vibratory filling of the Idaho calcine waste simulant into various convoluted hot isostatic pressing canisters. The simulation closely emulates the experimental vibratory powder-filling processes, achieving accurate representations of surface profiles and powder bed heights. Notably, the model underestimates lower fill levels but demonstrates improved accuracy at higher levels due to diminished air influence. Executed on a consumer-grade desktop PC, the DEM model replicates tapped powder bed heights to within millimeters, proving its capability to efficiently simulate commercial-scale bulk material handling processes using standard computing hardware.
