(Main)Nuclear energy - Determination of total hydrogen content in PuO2 and UO2 powders and UO2, (U,Gd)O2 and (U,Pu)O2 sintered pellets - Inert gas extraction and conductivity detection method (ISO 15651:2015)
Nuclear energy - Determination of total hydrogen content in PuO2 and UO2 powders and UO2, (U,Gd)O2 and (U,Pu)O2 sintered pellets - Inert gas extraction and conductivity detection method (ISO 15651:2015)
ISO 15651:2015 describes a procedure for measuring the total hydrogen content of UO2 and PuO2 powders (up to 2 000 µg/g oxide) and of U02 and (U,Gd)O2 and (U,Pu)O2 pellets (up to 10 µg/g oxide). The total hydrogen content results from adsorbed water, water of crystallization, hydro-carbon, and other hydrogenated compounds which can exist as impurities in the fuel.
Kernenergie - Bestimmung des totalen Wasserstoffgehalts in PuO₂- und UO₂-Pulvern und UO₂-, (U,Gd)O₂- und (U,Pu)O₂-gesinterte Pellets - Trägergasheißextraktion und Leitfähigkeitsbestimmungsverfahren (ISO 15651:2015)
Diese Internationale Norm legt ein Verfahren zur Messung des Gesamtgehalts an Wasserstoff in UO2- und PuO2-Pulvern (bis zu 2 000 μg/g Oxid) und in UO2- und (U,Gd)O2- sowie (U,Pu)O2-Pellets (bis zu 10 μg)/g Oxid) fest. Der Gesamtgehalt an Wasserstoff ergibt sich aus adsorbiertem Wasser, Kristallwasser, Kohlenwasserstoff und anderen hydrierten Verbindungen, die als Verunreinigungen im Brennstoff vorhanden sein können.

L'ISO 15651:2015 décrit un mode opératoire permettant de mesurer la teneur totale en hydrogène de poudres d'UO2 et PuO2 (jusqu'à 2 000 µg/g d'oxyde) et de pastilles d'UO2, (U,Gd)O2 et (U,Pu)O2 (jusqu'à 10 µg/g d'oxyde). La teneur totale en hydrogène provient de l'eau adsorbée, de l'eau de cristallisation, et des hydrocarbures et autres composés hydrogénés qui peuvent exister à l'état d'impuretés dans le combustible.
Jedrska energija - Ugotavljanje deleža vodika v PuO2 in praških UO2 ter v sintranih peletih UO2, (U,Gd)O2 in (U,Pu)O2 - Metoda z ekstrakcijo inertnih plinov in ugotavljanjem prevodnosti (ISO 15651:2015)
Standard ISO 15651:2015 opisuje postopek za merjenje deleža vodika v praških UO2 in PuO2 (do 2000 µg/g kisika) ter v peletih U02, (U,Gd)O2 in (U,Pu)O2 (do 10 µg/g kisika). Delež vodika je posledica absorbirane vode, vode kristalizacije, ogljikovodika in drugih hidrogeniranih spojin, ki so lahko prisotne v gorivu kot nečistoče.
