SVBR-75/100 -- Lead-bismuth cooled small power modular fast reactor for multi-purpose usage

Full text: Today's nuclear power is in the state of an intrinsic conflict between economic and safety requirements. This fact makes difficult its steady development. One of the ways of finding the solution to the problem is use of modular fast reactors cooled by lead-bismuth coolant that has been mastered in conditions of operating reactors of Russian nuclear submarines. Based on this experience, the small power fast reactor for multi-purpose usage (SVBR-75/100) has been developed. The small power reactors make it possible to fabricate the whole reactor at the factory and deliver it to the NPP site in practical readiness by using any kind of transport including the railway. Reactor installation SVBR-75/100 was designed in compliance with a conservative approach. This approach presumes to use to the maximal extent the technical solutions and temperature parameters, which have already been verified by operating experience. Further, when a one-through steam-generator producing over-heated steam is used, technical and economical parameters will be considerably improved. Technological maintenance of fissile materials non-proliferation has been ensured at all lifetime stages. Refuelling in developing countries has not been provided. On ending the lifetime (∼10 years), the reactor will be transported to the Supplier-country along with the core in the 'frozen' coolant. (author)
