impact of the progression of steel on top of a debris bed made of sub-oxidized corium particles, with simultaneous oxidation
In actual FCVS, several types of alkaline solution are used in the scrubbing stage to capture the radioactive iodine (I2). Therefore, it is difficult to remove CH3I by the alkaline solution, and molecular sieves such as silver zeolites installed downstream of the scrubbing stage are used to capture the organic iodide (CH3I). Silver nitrate aqueous solution (AgNO3 aq.) is highly reactive against iodine; hence, by using AgNO3 aq., the removal of organic iodide in the scrubbing stage can be expected.
