Title: RTF glovebox stripper regeneration development

Abstract

Currently, the Replacement Tritium Facility (RTF) glovebox stripper system consists of a catalytic oxidation front end where trace tritium which may escape from the primary tritium process into the glovebox nitrogen system is oxidized to tritiated water. The tritiated water, along with normal water which may leak into the glovebox from the surrounding atmosphere, is then captured on a zeolite bed. Eventually, the zeolite bed becomes saturated with water and must be regenerated to remain effective as a stripper. This is accomplished by heating the zeolite and evolving the trapped water which is then passed over an elevated temperature uranium bed. A waste minimization program was instituted to address this issue. The program has two parallel paths. One path investigates replacing the entire glovebox stripper system with a system of getters to scavenge trace tritium. This report concentrates on the second path, retaining the catalytic oxidation front end but replacing the uranium bed water cracking with alternative technologies.
