DESCRIPTION
This standard BS EN ISO 12800:2019 Nuclear fuel technology. Guidelines on the measurement of the specific surface area of uranium oxide powders by the BET method is classified in these ICS categories:
27.120.30 Fissile materials and nuclear fuel technology
ISO 12800:2017 gives guidelines on the determination of the specific surface area of as-fabricated uranium dioxide powder by volumetric or gravimetric determination of the amount of nitrogen adsorbed on the powder, and can be applied to other similar materials, e.g. U3O8, UO2-PuO2 powders, and other bodies with similar surface areas, e.g. powder granules or green pellets, provided that the conditions described are fulfilled. Modifications using other adsorbing gases are included. The method is relevant as long as the expected value is in the range between 1 m2/g and 10 m2/g.
