For example, the piping in the PRISM that carries the liquid sodium coolant around the reactor has two layers.
Each PRISM reactor has an intermediate sodium loop that exchanges heat between the primary sodium coolant from the core with water / steam in a sodium / water steam generator.
Several breeders have suffered sodium coolant fires, because sodium automatically burns in air and explodes in water.
Hans Bethe, Manhattan Project scientist and Nobel laureate, calculated in 1956 that if a breeder's liquid sodium coolant leaked out, it could melt in 40 seconds, become a small unintended atom bomb and spontaneously explode.

Unlike the current generation of light - water nuclear reactors, PRISM uses metallic fuel, such as an alloy of zirconium, uranium, and plutonium, and PRISM's fuel rods sit in a bath of a liquid metal — sodium — at atmospheric pressure, which ensures that the transfer of heat from the metal fuel to the liquid sodium coolant is extremely efficient.
It is the latest step in a sequence that began in December 2013, when the reactor was filled with its sodium coolant and received the necessary permits from Russian nuclear regulator Rostechnadzor to begin the fuel loading and pre-startup tests.
