(Main)Nuclear energy - Determination of nitrogen content in UO2, (U,Gd)O2 and (U,Pu)O2 sintered pellets - Inert gas extraction and conductivity detection method (ISO 12799:2015)
Nuclear energy - Determination of nitrogen content in UO2, (U,Gd)O2 and (U,Pu)O2 sintered pellets - Inert gas extraction and conductivity detection method (ISO 12799:2015)
ISO 12799:2015 describes a procedure for measuring the nitrogen content of UO2, (U,Gd)O2, and (U,Pu)O2 pellets. Nitrogen in nuclear fuel may be present either as elemental nitrogen or chemically combined in the form of nitrogenous compounds. The technique described herein serves to determine the total content of nitrogen excluding those compounds whose decomposition temperature is above 2 200 °C (most notably Pu and U nitrides).
Kernenergie - Bestimmung des Stickstoffgehalts in UO2-, (U,Gd)O2- und (U,Pu)O2-gesinterten Pellets - Schutzgasextraktion und Leitfähigkeitsbestimmungsverfahren (ISO 12799:2015)
Diese Internationale Norm beschreibt ein Verfahren zur Messung des Stickstoffgehalts von UO2, (U,Gd)O2 und (U,Pu)O2 Pellets. Stickstoff kann in Kernbrennstoff entweder als elementarer Stickstoff oder als chemische Verbindung gebunden in der Form von stickstoffhaltigen Verbindungen vorhanden sein. Die hier beschriebene Technik dient zur Bestimmung des Gesamtgehalts an Stickstoff, d. h. ohne die Verbindungen, die eine Zersetzungstemperatur von über 2 200 °C haben (allen voran Pu- und U Nitride).

L'ISO 12799:2015 décrit un mode opératoire permettant de mesurer la teneur en azote de pastilles d'UO2, (U,Gd)O2 et (U,Pu)O2. L'azote présent dans le combustible nucléaire peut soit se présenter sous la forme d'azote élémentaire, soit être combiné chimiquement sous la forme de composés azotés. La technique décrite dans l'ISO 12799:2015 permet de déterminer la teneur totale en azote en excluant les composés dont la température de décomposition est supérieure à 2 200 °C (principalement les nitrures Pu et U).
Jedrska energija - Določevanje dušika v sintranih peletih UO2, (U,Gd)O2 in (U,Pu)O2 - Metoda z ekstrakcijo inertnih plinov in ugotavljanjem prevodnosti (ISO 12799:2015)
Standard ISO 12799:2015 opisuje postopek za merjenje vsebnosti dušika v peletih UO2, (U,Gd)O2 in (U,Pu)O2. Dušik je v jedrskem gorivu lahko prisoten v obliki elementa ali v kemijskih dušikovih spojinah. Tehnika, opisana v tem dokumentu, se uporablja za določanje skupne vsebnosti dušika brez tistih spojin, ki se razgradijo pri temperaturi nad 2200 °C (predvsem Pu- in U-nitridi).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
