Safety analysis and CFD dispersion simulation of cryogenic release in a deep underground large scale cryogenic installation

This paper presents in brief the safety assessment of the underground installation at normal operation. In particular, the focus here is on the argon dispersion following a cryogenic release of gaseous argon in the underground premises. The paper is organized as follows. Section 2 gives a general description of the underground installation. Section 3 discusses briefly the quantitative risk assessment leading to the evaluation of accident frequencies. Section 4 presents the phenomenology analysis using CFD simulations of the argon dispersion. Section 6 concludes the work.
