Component and Material Investigations on Metal Seals for High Level Radioactive Waste Containers

摘要

1. Long-term investigations performed at BAM look to extend the state of knowledge on safety-related components of interim storage containers. 2. Metal seals act as the primary sealing barrier in the bolted double lid closure system of the containers. 3. The behaviour of metal seals has been investigated for ageing times up to 8.5 years and for various temperatures. 4. The main cause for reduction in useable resilience over time was due to creep deformation of the outer jacket of the seal.
