| titleOfInvention | How to monitor subcriticality |
| abstract | The present invention provides a method for monitoring subcriticality before becoming critical for a facility that handles nuclear fuel in an unsealed manner without directly measuring neutrons. A method of monitoring subcriticality in a nuclear facility that handles combustion fuel containing spontaneous fission nuclides in the fuel, the method comprising the step (A) of collecting fission product (FP) gas of the nuclear facility. , A step (B) of measuring gamma rays emitted from the FP gas and calculating krypton (Kr) and xenon (Xe) of the rare gas, and krypton at the generation position from the calculated krypton (Kr) and xenon (Xe) (Kr) and xenon (Xe) are calculated by attenuation correction, and a step (C) for determining a radioactivity ratio (R 0 (Kr / Xe)) of krypton (Kr) to xenon (Xe) at the generation position, FIG. based on the substantially linear relationship shown in, comprises radioactivity ratio (R 0 (Kr / Xe) ) step (D) to obtain the neutron multiplication factor (k eff) from the [Selection] Figure 2 |
