[2O09] Advanced Filtered Containment Venting System by Ionic Liquid
(4) Decomposition mechanism of ionic liquid mixed with water by gamma irradiation
Keywords:Severe accident, Filtered vent, Organic iodine, Ionic liquid, Irradiation
In order to improve the performance of the iodine removal system in a filtered containment venting systems in the event of a severe accident, we focused on ionic liquid. An ionic liquid mixed with water was irradiated with the cumulative dose assumed in a severe accident, and analyzed chemical structure of the irradiated ionic liquid. As a result, it was confirmed that the ionic liquid was hydrolyzed. However organic iodine could be removed even in the hydrolyzed ionic liquid.
