Influence of metallic silver and oxygen on the radiolysis of cesium iodide solutions

  • 1. Swiss Federal Institute for Reactor Research, Wuerenlingen (Switzerland)

Description

Silver iodide formation by radiolysis has been studied in the system water/cesium iodide/silver metal. In a number of scenarios for hypothetical core melt accidents, silver iodide has been considered as an effective scavenger for fission product iodine. The influence of dissolved oxygen and the consequences of a variable silver/cesium iodide ratio are shown in detail. Partial kinetic reaction constants for the different parameters are presented and it is shown that they can be simply added together to form an overall reaction rate constant. In a radiation field just short of 5 kGy/h, the influences of oxygen (air) and of the radiation are of the same order of magnitude. A linear relation is shown between specific metal surface and reaction rates. Data shown are compatible with earlier measurements made at Oak Ridge National Laboratory, US
