WPNCS Expert Group on Assay Data of Spent Nuclear Fuel (ADSNF)
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.
Main assignments of this Expert Group include:
analysing SFCOMPO database in order to assess the current situation and the need for new experimental data;
collecting new isotopic composition data from post-irradiation examination (PIE) and incorporating them and their associated operating histories/data into the SFCOMPO database;
archiving original reports on any PIE data included in the SFCOMPO database, as well adding data references that were used in the original development of the data; and
providing technical advice in support of PIE activities in member countries and promoting international collaboration.
Since 2012 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 SFCOMPO database is currently in its development version and is expected for public release in 2014.
