Rosenergoatom has reportedly postponed construction of the BN-1200\u00a0sodium-cooled fast neutron reactor at the Beloyarsk nuclear power plant \u201cindefinitely\u201d on the need to improve fuel for the reactor and amid speculation about the cost-effectiveness of the project.<\/strong><\/h4>\n

Russian nuclear engineering company OKBM Afrikantov is developing a BN-1200\u00a0reactor as a next step towards future reactor designs, commonly known as Generation IV.<\/p>\n

The reactor had been scheduled to start commercial operation in 2025, depending on experience of operating the pilot Beloyarsk 4, a 789\u00a0MWe fast-neutron reactor of the BN-800\u00a0design. The BN-800, which achieved first criticality in June 2014, has not yet started commercial operation. The Beloyarsk nuclear power plant, which is in the Sverdlovsk region in central Russia, has two shut down reactors and one in commercial operation\u00a0\u2014 the BN-600\u00a0Beloyarsk unit 3. The Beloyarsk 5\u00a0BN-1200\u00a0will use larger fuel elements than the BN-600\u00a0and BN-800\u00a0and have a simplified refuelling procedure. Maintenance work on Beloyarsk 3\u00a0is slated for completion on 26\u00a0May.<\/p>\n

The Russian Nuclear Community reported on its website atomic-energy.ru yesterday that a review of the decision to postpone the project might happen in 2020. Rosenergoatom director general Evgeny Romanov had said last July that Russia plans to start construction of three BN-1200\u00a0sodium-cooled fast neutron reactors before 2030. The first of these units would be located at the Beloyarsk nuclear power plant in Zarechny, in the Urals, he said.<\/p>\n

Beloyarsk Nuclear Power Plant general director Mikhail Bakanov told the Fast Neutron<\/em> nuclear industry newspaper recently that the decision to postpone the BN-1200\u00a0was \u201clike a bloody nose\u201d, but priority had to be given to Beloyarsk 4. \u201cOtherwise the toughest conclusion could be drawn that construction of fast reactor technology has been lost in Russia\u201d.<\/p>\n

BNPP chief engineer Yuri Nosov was quoted as saying on atomic-energy.ru that the BN-800\u00a0had been ready to start operations last year as planned, \u201cbut we are constantly thinking about what can be improved for its subsequent efficient operation. In particular, last year there was the need to improve the fuel, which is what we are working on now\u201d.<\/p>\n

Rosenergoatom spokesman Andrey Timonov added: \u201cFor us, the BN-800\u00a0is not only the basis for development of a closed nuclear fuel cycle. It is also a test case for technical solutions that will later be used for commercial production of the BN-1200. Among other things, the BN-800\u00a0must answer questions about the economic viability of potential fast reactors because at the moment \u2019fast\u2019 technology essentially loses this indicator [when compared with] commercial VVER units. However, we believe that if such a unit has more functions than to generate electricity, then it becomes economically attractive. That\u2019s what we have to find out\u201d. Timonov also said the company recognized that, from an economics point of view, the BN-800\u00a0is similar to the VVER-1000\u00a0reactor design, but that Rosenergoatom \u201cdoes not intend to abandon\u201d the BN-1200\u00a0project.<\/p>\n

Amid speculation about the economic viability of the BN-1200\u00a0project, Vitaly Petrunin, deputy director of OKBM Afrikantov, reportedly told a conference in Nizhny Novgorod this week that there was hardly any difference in the cost of developing the BN-1200\u00a0and the VVER-Toi (typical optimised, with enhanced information) design based on V-392M. Nuclear.ru<\/em> today quoted Petrunin as saying that OKBM Afrikantov is set to \u201cdefend\u201d the BN-1200\u00a0project in a meeting of Rosatom\u2019s scientific and technical council to be held in the second quarter of this year.<\/p>\n

Bakanov said last December that the BN-800\u00a0fast-neutron reactor was already providing operating and technological experience of value to the development of the planned BN-1200. Beloyarsk 4\u00a0is fuelled by a mix of uranium and plutonium oxides arranged to produce new fuel material as it burns.<\/p>\n

\u201cBN-800\u00a0is the successor to the BN-350\u00a0and BN-600\u00a0reactor units\u201d, Bakanov said. \u201cBut the fact it has a large number of structural and technological improvements means it has trial status, like all the previous BNs. The priority of the BN-800\u00a0then is not so much the production of electricity,\u201d Bakanov said. \u201cIt\u2019s a commonly known fact that the economics of a trial design are inferior to a serial product, in this case a commercial VVER. The main objective of the BN-800\u00a0is [to provide] operating experience and technological solutions that will be applied to the BN-1200\u201d.<\/p>\n

Atomenergoproekt announced the VVER-Toi design in 2010. This design has an upgraded pressure vessel, increased power to 3300\u00a0MWt and 1255\u20131300\u00a0MWe gross (nominally 1300), improved core design to increase cooling reliability, further development of passive safety with 72-hour grace period requiring no operator intervention after shutdown, lower construction and operating costs, and 40-month construction time. It will use a low-speedturbine-generator. The project was initiated in 2009\u00a0and the design was complete at the end of 2012.<\/p>\n

Fundamental features of the BN-800\u00a0reactor include an active reactor protection system with a passive system that works automatically in the event of loss of sodium-cooling liquid pressure.<\/p>\n","protected":false},"excerpt":{"rendered":"
