Description

In the fast reactors, it's crucial to install an effective failed fuel detection and location (FFDL) system for the purpose of protecting workers from radiation exposure and reducing radiation contamination. A new type of FFDL technique focused on the gas tagging method has been proposed by using resonance ionization mass spectrometry (RIMS) for the isotope analysis of the Ar cover gas. Though precise analysis of ppt level Kr and Xe in Ar needed is difficult because of the Ar+ and Ar2+ ions generated by the photoelectron, we could successfully decrease the signal amount of these ions by applying an electrode with a slit-type hole to permit ppt level detection of 80Kr without any obvious Ar2 interference. Some promising methods concerning effective utilization of laser light are also presented to increase the photoionization efficiency for further reliability improvement of RIMS in the FFDL system.
