Abstract
By the  decision of the Board of the Ministry of Atomic Energy dated 05.03.1997  (announced by Order of the Minister No. 130), the BR-10 research reactor was  designated as a technological testing ground for the implementation of the fast  reactors with alkaline liquid metal coolants decommissioning program. To solve  the problem of conditioning alkaline waste in IPPE JSC, it was proposed to use  the dump granulated slag of the furnaces of the copper smelting plant of the  Karabash combine, containing iron oxides FeO (35–38 %) and Fe2O3  (12 %), silicon SiO2 (34–36 %), aluminum Al2O3  (5–8 %), calcium CaO and magnesium MgO (6 to 10–15 % in total) are  the main components of the slag, the impurities are ZnO oxides (2.0–2.5 %)  and CuO (up to 0.5 %).
 Experimental studies of the solid-phase technology (SPT) method were carried  out on the stands MINERAL-3, MINERAL-30, MINERAL-50. The SPT technology is used  for processing radioactive waste of alkaline liquid metal coolants on the BR-10  IR at the MAGMA-SPT module. The results indicate the prospects for the  development of this method and the creation on its basis of an optimized  technology for processing radioactive waste of alkaline liquid metal coolants.
The construction of pilot production of sufficient productivity on the  basis of a fully functional sample of the MINERAL-100/150 series installation  being created for its implementation in the decommissioning programs of reactor  plants with alkaline liquid metal reactor plants BOR-60, BN-350, BN-600, with preliminary testing of optimized technology on a sample of the  MINERAL-100/150 installation on the IR BR-10 of IPPE JSC.
