TRAPPING OF NOBLE RADIOACTIVE GASES AND THEIR DECAY PRODUCTS UNDER STATIC AND DYNAMIC CONDITIONS BY HIGHLY POROUS MATERIALS

The paper presents the adsorption isotherms for noble gases, in particular, argon, krypton, xenon, calculated assuming static and dynamic conditions based on the VSK-5 charcoal. It proposes methods to describe the obtained dependences that can be further used to calculate Henry’s constants. In case of pulse-mode supply of the noble gas under dynamic conditions, relevant calculations are reduced to the Shilov equation that is solved after the adsorptive output curves are fitted. The paper presents the approaches developed to measure the radon trapping efficiency from the air of RW storage facilities.

 

Keywords: radioactive waste, radioactive noble gases, sorption, adsorbents, trapping efficiency, adsorption coefficient.
