| titleOfInvention | Dual-cooled nuclear fuel rods whose thermal resistance in the inner coolant direction is greater than the thermal resistance in the outer coolant direction |
| abstract | The present invention relates to a dual-cooled nuclear fuel rod in which the thermal resistance in the inner coolant direction is greater than the thermal resistance in the outer coolant direction.n n n According to an embodiment of the present invention, a dual-cooled nuclear fuel rod having a thermal resistance in an inner coolant direction greater than a thermal resistance in an outer coolant direction is provided with an inner cladding tube having a coolant flowing inward inside an outer cladding tube through which coolant flows outward. An annular sintered body is provided between the outer and outer cladding tubes, and includes an annular end cap sealing both ends of the inner and outer cladding tubes, and the annular sintered body has a density of 94% TD or more and 100% TD or less, and the annular sintered body When the density of 94% TD to 97% TD, pores are present in the annular sintered body at a volume ratio of 3 to 6%, and less than 3% of the volume occupied by the pores is made of pores having a size of less than 10 μm. The inner gap between the inner sheath and the annular sintered body is relatively larger than the outer gap between the outer sheath and the annular sintered body It can be made with the same gap.n n n According to the above configuration, the present invention can relatively improve the heat resistance in the inner coolant direction during combustion to suppress excessive heat transfer in the inner coolant direction by increasing the heat resistance in the inner coolant direction, and the nuclear fuel due to the heat flux in the inner sheath. The damage of the can be prevented, and the safety of the LWR can be secured.n n n n Reactor, Nuclear Fuel Rod, Coolant, Heat Resistance, Heat Flux, Gap, Densification, Swelling |
