SYSTEM AND METHOD FOR IMPROVING SENSITIVITY OF A SIPPING SYSTEM |
摘要 |
A method and system detects failures in nuclear fuel assemblies. A water treatment device degasses/removes fission gases from water used in the canister of a vacuum sipping device. A sipping procedure then detects a failure in a fuel assembly in the canister. The degassing improves a signal-to-noise ratio of the detector used during the sipping process, and improves the failure detection sensitivity of the system. Additionally and/or alternatively, gas may be recirculated through the canister water before the vacuum is applied so that fission gas concentration in the recirculating gas reaches a baseline equilibrium with the canister water. The vacuum is thereafter applied and the sipping procedure proceeds such that an increase in detected radioactivity over the baseline equilibrium indicates a leak in the fuel assembly. |
