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.

Nuclear fuel must be of high quality before being placed into service in a reactor. Nuclear fuel vendors currently use manual inspection for quality control of the nuclear fuel pellets before they are inserted into the zirconium fuel rods and bundled into assemblies. The feasibility of automating the pellet inspection process using artificial neural networks is examined to improve accuracy, speed, and cost; to reduce employee radiation doses; and to provide defect statistics to the fuel manufacturer. Sample nuclear fuel pellets (252 pellets) are photographed and scanned, and appropriate feature extraction techniques are developed and applied to the scanned images. The extracted features are then used as inputs to a backpropagation neural network. The results indicate that a backpropagation neural network is capable of classifying pellets as good (passing) or bad (failing) with high accuracy.
