The eutectic composition f this system, known as Lead-Bismuth Eutectic (LBE), is sometimes used as a heat transfer fluid in nuclear eactors. LBE reactors famously powered the Soviet Alfa-class nuclear-powered attack submarines, which vere the fastest submarines ever built - at least, the fastest submarines that the public knows about.

The experience of using lead-bismuth coolant in Russian nuclear submarine reactors has been presented. The fundamental statements of the concept of using the reactors cooled by lead-bismuth alloy in nuclear power have been substantiated. The key results of developments for using leadbismuth coolant in nuclear power have been presented.

Lead–Bismuth Eutectic (LBE) has been considered as a nuclear reactor coolant candidate for more than 50 years. In Russia, LBE cooled reactors were developed for 'Alpha'-class nuclear submarines. During the period from the mid-1960s until the 1990s, it achieved about 80 reactor-years of operating experience. ...
