Abstract
By using the metal fiber technology, silver zeolite technology, scrubbing technology, etc. established by filtered containment venting system, FCVS an air purification system that can be used under a wider range of conditions is expected.
The metal fiber filters and silver zeolite (AgX, etc.) that have a proven track record in Filtered Containment Venting System(FCVS) are nonflammable and can be used even at high temperatures. And also scrubbing technology is greatly improve the decontamination factor (DF) of radioactive substances. And also scrubbing technology is greatly improve the decontamination factor (DF) of radioactive substances. The system is expected to be used in a wide variety of ways such as by moving to an emergency evacuation site or a highly polluted place in the event of an accident to supply clean air for We manufactured the prototype of portable air purification system in 2020. As a result, we confirmed the high adsorption performance of organic iodine and the high collection rate of barium sulfate.
In this paper, we will propose a safer air purification system that can prevent the exposure of nuclear workers by using silver zeolite, which has excellent adsorption performance.
