Abstract
This paper deals with the cryogenic risk arising from nitrogen spillage in a box
located in Hall A of the underground laboratories of the Gran Sasso National
Laboratory, Assergi (L’Aquila). This box will be used as a storage area for some
sensitive material (crystals) which will be used for an experiment called
\“CUORE”. Starting from the Fault Tree Analysis (FTA), in order to estimate the
global risk for human activities, a consequence analysis has been performed,
using EFFECTS software models. The gap between the latest and the real
scenario has been covered by a real test during which a \“monitored, measured
and controlled” gas nitrogen flow has been spilled into the box. Furthermore, a
description of a reliable base for computational fluid dynamics (CFD) analysis is
treated.
Keywords: safety, cryogenic, ODH, FTA, CFD, confined space, underground
laboratory.
