Abstract

Abstract: A delay bed system for evaluating the performances of various kinds of activated carbons is established, and the retaining performances for radioactive krypton and xenon with different kinds of activated carbons were conducted. The effects of parameters, including system pressure, temperature of carrier gas, gas flow rate, and radiation intensity, etc., on retaining performances for krypton and xenon with activated carbons were carried out. It is known from experimental results that dynamic adsorption efficiency becomes bigger when pressure becomes higher and temperature becomes lower, and the affections of gas flow rate and radiation intensity are slight and neglected. The selected kinds of activated carbons all have satisfied physical properties and retaining capability for radioactive noble gas. The selected kinds of activated carbons satisfy the design requirements of radioactive gaseous treatment system and can be used in nuclear power plants.

Key words: retaining performances, dynamic adsorption efficiency, gaseous treatment system
