In 2013-2015 NW SPTC Socium Working Group carried out a number of R&D works in Gremikha department of Northwest Center SevRao.

NW SPTC Socium Working Group report was approved by RosRao Scientific and Technical Council (STC RosRao proceedings from 29.05.2014) and by ROSATOM (ROSATOM letter from 16.06.2014).

NW SPTC Socium Working Group and experts from Gremikha department of Northwest Center SevRao carried out the final stage of R&D on the basis of procedure developed by RAS Kola Science Centre on a bigger volume of LNW (from 1 litre and more) with the use of LHT-9 adsorbent and final production of titanate-silica ceramics.

The experiments on reprocessing non-scheduled ultra-acid waste doped with europium were carried out on worked out fuel discharged from liquid metal cooled reactor on nuclear submarine #910, project 705. The experiments were made with the use of LHT-9 and proved its high efficiency in reprocessing europium doped LNW (40-100 gr of LHT-9 per 1 litre of LNW). The sorbent can be used in the form of water suspension, which is mixed with LNW without any preliminary treatment (dilution, neutralization, etc.).

As a result of R&D on sorbents, academician V.T. Kalinikov proposed to establish a center for synthesis of new functional materials (sorbents) in Apatity science campus (Fersmana str., 34). RosRao together with experts from NW SPTC Socium, RAS KSC nanocentre and Saint-Petersburg State University have conducted several meetings on reprocessing of scheduled and non-scheduled liquid radioactive waste into durable titanate ceramics for long-term immobilization of most radionuclides. The list of the equipment necessary for establishing a centre for new functional materials (CNFM) in Apatity has been developed and delivered to RosRao.

Besides, at this stage scientists managed to synthesize a number of new titanate sorbents, which are capable to effectively purify liquid radioactive waste (LRW) and which allow their further long-term disposal in the form of durable solid raw material (titanate ceramics). It is a real breakthrough that many laboratories in the world, which deal with LRW purification, have been striving for. This method of LRW utilization has been approved by RosRao administration and scientific and technical council and patented by us.
