Aspects of the Cryogenic Equipment Mechanical Calculations on an Example of the FRESCA2 Cryostat

The feature of all cryogenic equipment is that they operate at extremely low temperatures. Typically, a liquid gas flows through or is stored in such devices. In order to ensure that such processes are technically and economically viable, each cryogenic device must have high quality thermal insulation which will reduce heat inleaks into the cryogen. Therefore, the vast majority of cryogenic devices employ vacuum insulation, which entails the need to use an additional vessel on the outside of the vessel or the pipes in which the cryogen is stored. Mechanical calculation of the cryogenic equipment should include both the vacuum vessel loaded with external pressure and the cryogenic vessel loaded with internal pressure. Additionally, the calculations should include potential emergency states and loads during the equipment production tests. This paper presents all the described aspects of mechanical calculations on the example of the FRESCA2 (Facility for Reception of Superconducting Cables) test station currently under design in collaboration between European Organization for Nuclear Research CERN (Switzerland) and Wroclaw University of Science and Technology (Poland)
