Summary: | In this work, prompt gamma ray neutron activation analysis technique was used to monitor the REEs saturation in resin. A facility consisted of a D-T neutron generator, a BGO detector and a 3He detector was established and applied to analyze REEs (Gd and Sm) samples. Neutron self-shielding effect was also corrected. The enriched Gd and Sm in resin were close to saturation at about 400 min. The results showed a satisfactory agreement with the XRF tests, which demonstrated that PGNAA was sufficient for monitoring REEs saturation in resin.
•A PGNAA method for rare earth ion exchange resin saturation analysis was proposed.•The change of REEs content in resin column was monitored directedly for resin saturation analysis.•A PGNAA setup with DT neutron generator and BGO detector was used to monitor the REEs saturation in resin. |
