Minor Actinide Property Database

The Minor Actinide Property Database (MADB) is a bibliographic database on physico-chemical properties of selected Minor Actinide (MA) compounds and alloys.

Recently, the scope of R&D activities is increasing among Member States on several facets of Minor Actinide (MA) elements (namely Am, Np, and Cm) and their compounds owing to their accumulation in significant quantities by enhanced use of nuclear energy. These artificial elements pose a very long-term radiological toxic burden to the environment, which has become a limiting factor for the growth of nuclear energy.

The issue of mitigation of radiological toxicity of actinides by advanced P&T methods has been addressed by the IAEA in its several meetings and TECDOCs. Recent global R&D efforts on advanced P&T methods in the last two decades have generated considerable information/data on MAs and its compounds encompassing various aspects of advanced nuclear fuel cycles.

To enhance the capacity of interested Member States in developing innovative nuclear fuel cycle technologies, it is deemed necessary to develop a database on physico-chemical properties of MAs and its compounds. In this regard, the IAEA initiated an activity to create an electronic database which will be easily expanded and updated and disseminated through the internet to the interested parties.

The MA materials and properties are selected based on their importance for the use in advanced nuclear fuel cycle especially for the partitioning and transmutation.
