しく単純化できる。Six intermediate heat exchangers 11 with built-in pumps are installed in the circumferential direction as shown in FIG. However, since the installation space for four sodium pumps is no longer required compared to the conventional method, the diameter of the roof slab 3 can be significantly reduced, and the diameter of the furnace vessel 2 can be significantly reduced. Since the number of bales installed through the roof slab 3 is reduced, the roof slab 3
This increases the rigidity of the reactor and improves the earthquake resistance of the fast breeder reactor. Most of the sodium cooled in the intermediate heat exchanger is transferred to impeller 1.
5 and directly to the reactor core 1 through the sodium supply pipe 22, it is possible to eliminate the uneven sodium flow within the lower brenum 6 between the intermediate heat exchanger and the sodium pump as in the prior art. Furthermore, even if the intermediate heat exchanger loses its heat exchange capacity, high-temperature sodium will substantially flow through the upper plenum 5, the casing 12, and the sodium supply pipe 22. Of course, the hot shock imparted to the structure 9, especially the core support structure 7, is significantly alleviated. Furthermore, impeller 15
Since a part of the sodium discharged from the furnace vessel 2 is used for cooling the side wall of the furnace vessel 2, the cooling mechanism for the side wall of the furnace vessel 2 can be significantly simplified.
