FIRE EXTINGUISHING FACILITY FOR LIQUID LITHIUM

PROBLEM TO BE SOLVED: To provide a fire-extinguishing facility for liquid lithium that can quickly and surely restrain heating of liquid lithium. SOLUTION: When liquid lithium Li leaks and temperature rises at a site where the liquid lithium is used, a remote control valve 15 provided in a feed pipe 10 connecting a sealed container 7 to a nozzle 8 is opened by an actuation signal 15s output by a control means 12 according to a temperature detection signal 9s from a temperature detecting means 9 placed in the site, and argon gas in a gas source 11 and a powder fire extinguisher 6 with an apparent density of 0.5 or less in the sealed container 7 spew from the nozzle 8 via the feed pipe 10 to cover the liquid lithium Li leaking into the site where the liquid lithium is used.
