Tritium Containment Vessel Response to Thermal and Mechanical Abuse Environments for Fire Safety Assessments

Shurtz, Randy; Cruz-Cabrera, Alvaro A.; Fitzgerald, Carl; Takahashi, Lynelle K.

This report evaluates leakage behavior from tritium containment vessels under thermal abuse and combined thermal-mechanical abuse conditions to better understand safety implications for releases occurring in a fire scenario. Surrogate gases were used for all tests in this report. Leakage through the valves from thermal pressurization was observed when heating rates >0.8°C/s were sustained to >300°C. Gas plumes were visualized from vessels that were heated above 260°C and then dropped.
