The EVEDA lithium test loop is constructed at the Oarai Research and Development Center, Japan Atomic Energy Agency. Since lithium is specified as a dangerous substance by a Japanese law, the countermeasure which assumed the lithium combustion incident is indispensable. In this experimental study, the fire-extinguishing behavior of four kinds of fire extinguishers - dryness sand, pearlite, Natrex-L and Natrex-M - to burning lithium was examined. In addition, the effect of depth of lithium pool on the fire-extinguishing performance of the candidate fire extinguisher was investigated to determine the amount of the fire extinguisher placed at the EVEDA lithium test loop.

In order to obtain the engineering data of the lithium target system which is the neutron source of the International Fusion Material Irradiation Facility (IFMIF), design and fabrication of the liquid lithium test loop are carrying out under the Engineering Validation and Engineering Design Activity (EVEDA). Since lithium is specified as the dangerous substance by the Japanese law, the countermeasure which assumed the lithium combustion incident is indispensable. This report summarizes the results of basic experiment on fire-extinguishing of the lithium. In this experiment, the fire-extinguishing behavior of the fire extinguishers to the lithium was experimentally confirmed, and the fire extinguisher for the liquid lithium test loop is proposed. In addition, the fire-extinguishing performance for the determination of the amount of dispositions of the fire extinguisher was experimentally estimated.
