Title Graphite Compressive Creep Capsule Design for Irradiation in the HFIR.

Abstract The subject of graphite irradiation creep characteristics is of great interest to the nuclear industry. Designing experiments for graphite creep is problematic because of the very substantial dimensional evolutions that occur in the material during radiation which makes maintaining specimen conditions (load and temperature) difficult without actively controlling the experiment. The work described in this paper proposes a new capsule design that does not rely on active control for specimen loading or temperature control. Active control methods may provide finer tuned parameters within the creep capsule, but these systems require complex and extensive infrastructure that can fail during usage. The passive system described in this paper suggests a more reliable and robust approach.
