SFCOMPO Spent Fuel Isotopic Composition Database

Under the guidance of the Working Party on Nuclear Criticality Safety, the Expert Group on Assay Data of Spent Nuclear Fuel is responsible for the maintenance of the NEA spent fuel isotopic composition database SFCOMPO.

The SFCOMPO database of nuclide compositions of spent nuclear fuel is hosted by the OECD Nuclear Energy Agency since 2001. In 2012 and 2013 a collaborative effort led by the NEA Expert Group on Assay Data of Spent Nuclear Fuel, has resulted in the creation of a new enhanced relational database structure and a significant expansion of SFCOMPO, now containing experimental assay data for a wide selection of international reactor designs. This new database is currently in its development version expected for public release in 2014.
