Abstract: This work considers the safety analysis and quantitative risk assessment of a cryogenic installation located in specially excavated caverns 1400m underground. The installation includes a custom-designed heat insulated Tank hosting over 65kt of cryogenic argon. The conditions inside the Tank and its cavern will be maintained using appropriate process systems for cooling, heating, pressurization and filtration. Smaller adjacent caverns will host the auxiliary process equipment. This paper identifies the possible hazards, quantifies accident occurrence frequencies, and performs detailed simulations of accidental argon release due to pressure control failures. The quantitative results indicate weak spots for improvements on the current process design of the installation.
