Popis
BS EN ISO 12799:2019
This standard BS EN ISO 12799:2019 Nuclear energy. Determination of nitrogen content in UO2, (U,Gd)O2 and (U,Pu)O2 sintered pellets. Inert gas extraction and conductivity detection method is classified in these ICS categories:
- 27.120.30 Fissile materials and nuclear fuel technology
This International Standard 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).
