Nuclear power of the future will be represented by a dual component energy system dominated by VVER reactors with gradually increasing proportion of sodium fast reactors SFR, joint with a singular closed MOX fuel nuclear cycle. The components of such system play the following parts. 1. Reactors SFR: – Base-load production of power; assumes power manoeuvrability within the limits of 100 – 75 – 100%; – Utilizes accumulated depleted or reprocessed uranium for refuelling, produces plutonium most suitable for manufacturing MOX fuel for VVER; – Burns up long-life high-level waste (minor actinides partitioned during reprocessing of spent nuclear fuel from SFR and VVER). 2. Reactors VVER: – Produces power according to the system power manoeuvrability mode; – Uses MOX fuel instead of UO2; – Exported with the option of returning SNF back to Russia; – Plutonium extracted from VVER spent fuel is used for MOX fuel manufacturing for SFR. 3. Nuclear fuel cycle industries: – Provide reprocessing of SNF from VVER and SFR, extracting of nuclear materials for recycling; – Use depleted or reprocessed uranium and plutonium from spent nuclear fuel to manufacture MOX fuel; – Provide partitioning of RAW in order to consequently utilize minor actinides and reduce the risk of proliferation of nuclear materials; conditioning and disposal of RAW. This article presents several ways of establishing the dual component system with CNFC, as well as the new business approach to rendering CNFC services to foreign investors.
