Abstract | The cryogenic system uses liquid helium and liquid nitrogen to cool the superconducting cyclotron magnet and its cryopanels. In order to assess safety scenarios subsequent to an unusual leakage of cryogens from the system, a deterministic analysis has been carried out to estimate the variation of oxygen concentration with time at several locations of superconducting cyclotron building. The entire process is simulated assuming evaporated cryogens mixes instantaneously with air in the confined space, the ventilation system of the cyclotron building is operational, fresh air continuously enters the confined volume and mixes instantaneously with air in the confined space. |
