Description
Oak Ridge National Laboratory has developed a specialized pressure relief device capable of functioning in cryogenic environments below 20 K, such as those used for fusion cryogenic fuel handling. Unlike conventional single use burst disks, this device can operate multiple times without degradation under extreme thermal and pressure conditions. It is compatible with radioactive tritium gaseous fuel and can act as both a relief and check valve, regulating pressure differentials of one bar or greater. The design incorporates a unique configuration of materials and mechanisms suited to sustained exposure to low temperatures and tritium gas, ensuring safety and reliability in advanced fusion energy applications. This innovation addresses the need for durable, reusable safety components in fusion fuel systems.
