トの建屋が大型化するという問題があった。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.
The temperature of the secondary coolant is as high as 400 to 500C, and the piping of the secondary coolant circulation system that guides it is made thin to reduce thermal stress. For this reason, the pipes are made to meander (route) to ensure their rigidity.
Next, the piping of the coolant circulation system becomes longer and the weight of the piping alone becomes extremely heavy. Moreover, since the pipes are routed around, the overall size of the fast breeder reactor plant becomes large, and the building of the plant also becomes large.

その外寸−辺当り２０ｍ程度短縮された。As described above, the present invention provides a reactor vessel, a primary coolant circulation system that includes an intermediate heat exchanger and a primary circulation pump connected to the reactor vessel via piping, and a coolant circulation system that passes through the intermediate heat exchanger.
Liquid metal cooled fast breeder comprising a secondary coolant circulation system having a steam generator and a secondary circulation pump that heats the received feed water to generate steam using the secondary coolant heated by the secondary coolant. In the furnace, the intermediate heat exchanger, the steam generator, the primary circulation pump, and the secondary circulation pump are installed in the same tank, so most of the piping is unnecessary in the secondary coolant circulation system. As a result, the length and weight of piping in the entire fast breeder reactor plant was significantly reduced, and the fast breeder reactor plant building was converted into a shed. Incidentally, in the chillup-scale fast breeder reactor plant shown in Fig. 1, the length of piping was reduced by about 1400 m, the weight by about 470 tOl, and the building was shortened by about 20 m per side.
