、同プラントの建屋が大型化するという問題かあった。Regardless of the reactor type, a liquid metal cooled fast breeder reactor is equipped with an intermediate heat exchanger, primary circulation pump, secondary circulation pump, steam generator, etc. around the reactor. Depending on how these devices are arranged, they are classified into loop type, tank type, satellite type, etc. In all types of fast breeder reactors, the temperature of the secondary coolant is as high as 400 to 500 degrees Celsius, and The piping of the secondary cooling old circulation system is made thin to reduce thermal stress. For this reason, the piping is meandered (routed) to ensure initial rigidity, and the piping for the secondary cooling control R system is long, and the weight of the piping alone is extremely heavy. Moreover, since the piping was routed around, the overall size of the fast breeder reactor plant became larger, which led to the problem that the plant building would become larger.
