| abstract | (57) [Problem] To provide a mixed oxide fuel assembly having a 9 × 9 shape and maintain the fuel rod integrity without excessively increasing the fuel rod internal pressure even when burned to a high burnup. Obtain a possible fuel assembly. SOLUTION: A mixed oxide fuel rod 2 in which a plurality of mixed oxide pellets 6 obtained by sintering a mixture of plutonium oxide and uranium oxide are loaded into a cladding tube 7 and both ends are sealed with end plugs 9 and 10 is provided. A uranium oxide fuel rod 3 loaded with uranium oxide pellets 12 obtained by sintering uranium oxide alone or by mixing a neutron poison into a cladding tube having the same shape as the mixed oxide fuel rod 2; And a mixed oxide fuel assembly formed by bundling water rods in a square grid of 9 rows and 9 columns. Helium gas of 0.3 to 0.5 MPa is sealed in the internal free space of the mixed oxide fuel rod 2 at the time of manufacture, and about 1.0 MPa of helium gas is manufactured in the internal free space of the uranium oxide fuel rod 3 at the time of manufacture. Gas is enclosed. |
