Abstract
This report documents the beyond-design-basis test results of the performance of one metallic and two elastomeric seals typically used in spent fuel transportation packages. Tests were conducted using a scale-model package made of stainless steel SS 304 filled with helium initially at either 5 bar or 2 bar at room temperature. The test package was then exposed in an electrical furnace to temperatures over the specified maximum operating temperatures of these seals for a pre-determined period (typically 9 h). The overall goal of the project is to determine the beyond-design-basis thermal performance of these seals.
