| titleOfInvention | Damage detection method for nuclear fuel |
| abstract | (57) [Summary] [Purpose] It is possible to detect radioactive fission products released into Na of coolant due to damage of nuclear fuel without being affected by Na ions, and to accurately and promptly detect damage of nuclear fuel. It is possible to estimate the extent of damage and the location of damage to nuclear fuel. [Structure] When the nuclear fuel in the fast breeder reactor is damaged, the coolant Na The radioactive fission product released into the sample is detected by the resonance-sensitized ionization method. At that time, the laser beam from the excitation laser 1 used in the resonance sensitized ionization method → the wavelength tunable laser 2 → the beam splitter 3 → the mirror 5 is introduced into the fast breeding furnace 8 by the optical fiber 6 and collected by the optical lens 9. Light, space with a diameter of 5 mm or less, more preferably 1 mm Only radioactive fission products existing in the following spaces are ionized to detect the radioactive fission products, or two metal plates 32 and 33 are installed in the fast breeder reactor 8 to enable measurement of electric conductivity. The radioactive fission product is ionized between the metal plates 32 and 33, and the radioactive fission product is detected by the change in electric conductivity. Then, the radioactive fission product is detected for cesium. |
