The water glass type neutron absorber has been developed as a measure to precaution of re-criticality during fuel debris retrieval. Since the neutron absorber covers the surface of the fuel debris, the drying of the water content of the fuel debris was suggested to be hindered. The drying test using the mock test piece was carried out in order to evaluate the effect on the drying behavior when the surface of the fuel debris is covered with the neutron absorber. We investigate the drying characteristic curve of the mock test piece by thermogravimetric analysis, and report the evaluation of drying behavior.

The water glass type neutron absorber has been developed as a measure to precaution of re-criticality during fuel debris retrieval at the Fukushima Daiichi Nuclear Power Plant. The drying test using the mock test piece was carried out in order to evaluate the effect on the drying behavior. In this report, the scale-up tests was shown.

The water glass type neutron absorber has been developed as a measure to precaution of re-criticality during fuel debris retrieval from nuclear reactor, etc. Since the surface of the fuel debris is covered with the neutron absorber, the coating of the neutron absorber was suggested to inhibit the evaporation of water in the debris during the drying process of fuel debris. The drying test using the mock test piece was carried out in order to evaluate the effect on the drying behavior when the surface of the fuel debris is covered with the neutron absorber. The outline and basic study of the drying test will be reported in this presentation.
