• Uranium• Mixed U-Pu• Th based (?)
• Cooling time• Burnup• MA strategy
The country which first develop a breeder reactor will have agreat competitive advantage in atomic energy

2International Pyroprocessing Research Conference
Demands on reprocessing in Russia
• Fast reactors “dense” spent fuel reprocessing;
• Fuel cycle closing for all actinides;
• Process losses less than 0,1%
• No more than 1 year cooling time;
• Avoid the production of pure plutonium
• Eliminate long-term storage of high-andintermediate-level waste in liquid andgaseous form;
3International Pyroprocessing Research Conference
“Ultima ratio”
Rosatom starts project for creation newexperimental facility for feasibility demonstration,full-scale reprocessing experiments, industrialequipment prototype lifecycle test, safety andeconomic assessment of different technologies(exist or under development).
Polyfunctional Radiochemical Complex (PRC)
have to be designed as next generation plantprototype
PRC will be placed on RIAR site
International Pyroprocessing Research Conference 4
PRC’s main principles• “Hot” spent nuclear fuel
• All type of FA FR – existed or at designed will be able to get toPRC;
• Modularity of hot cells and technological equipment
• Equipment prototype will provide high throughput equal toplant line;
• Full SNF reprocessing lifecycle test:
o Technology;
o Equipment maintainability and repair;
o Final disposal of technological apparatus and safety equipment;
o Treatment for all kind of RAW;
• Lack of liquid HLW
• Decrease of secondary RAW amount
• Full-scale automation;
• Wide implementation of the robotics technologies.
