Abstract

SAES metal getter material St 198 was chosen for glovebox stripper tests to evaluate its effectiveness of removing tritium from a nitrogen atmosphere. The St 198 material is unique from a number of other metal hydride-based getter materials in that it is relatively inert to nitrogen and can thus be used in nitrogen glovebox atmospheres. Six tritium stripper experiments which mock-up the use of a SAES St 198 stripper bed for a full-scale (10,500 liter) nitrogen glovebox have been completed. Experiments consisted of a release of small quantity of protium/deuterium spiked with tritium which were scaled to simulate tritium releases of 0.1 g., 1.0 g., and 10 g. into the glovebox. The tritium spike allows detection using tritium ion chambers. The St 198 stripper system produced a reduction in tritium activity of approximately two orders of magnitude in 24 hours (6--8 atmosphere turn-overs) of stripper operation.

Tritium stripping in a nitrogen glove box using palladium/zeolite and SAES St 198{trademark}

Conference Klien, J; Wermer, J

Glove box clean-up experiments were conducted in a nitrogen glove box using palladium deposited on zeolite (Pd/z) and a SAES St 198{trademark} getter as tritium stripping materials. Protium/deuterium samples spiked with tritium were released into a 620 liter glove box to simulate tritium releases in a 10,500 liter glove box. The Pd/z and the SAES St 198{trademark} stripper beds produced a reduction in tritium activity of approximately two to three orders of magnitude and glove box clean-up was limited by a persistent background tritium activity level. Attempts to significantly reduce the glove box activity to lower levels without purging weremore » unsuccessful.« less

Removal of deuterium from flowing nitrogen by SAES St 198

Technical Report Nobile, A

Testing was conducted to investigate the ability of a metal getter, SAES St 198, to remove D[sub 2] from flowing nitrogen. This getter is being considered for applications involving removal of tritium at low concentrations from glovebox atmospheres and inert or nitrogen process streams. This document reports results from tests involving flow of 107 ppM D[sub 2] in nitrogen through a packed bed of St 198 getter granules (1.02 mm average dia) at a gas flow rate of 400 std. cm[sup 3][center dot]min[sup [minus]1].

SAES St 909 Getter Testing at the Savannah River National Laboratory

Conference Klein, J; Holder, J

Process gas tritium stripper technology has gone from catalytic oxidation followed by absorption on molecular sieve/zeolite beds to non-evaporate metal getter technology. SAES Getters produces a number of commercial getter products including St 909. St 909, a Zr-Mn-Fe alloy, is sold in pellet form, can decompose (''crack'') a number of process gas impurities, and retains lower levels of tritium than other getters. The performance of this material to remove process impurities, especially methane, under of variety of operating conditions has been part of a Savannah River National Laboratory (SRNL) for five years. St 909 has been tested at the benchmore »« less
