Russland hat den einzigen „Schnellen Brüter“ Reaktor in Betrieb gesetzt

Auf vielen Gebieten haben die Russen inzwischen die USA auch technisch überholt, welche nicht einmal mehr eine Kaffee Maschine produzieren können und nur Müll Militär Schrott produzieren wie die F-22 – F-35 und deren Militär Technik wie Radar Ziel Erfassung Funkionen einfach durch Russische Technik ausgeschaltet wird.

Fast reactor starts clean nuclear energy era in Russia

Controlled nuclear fission has been started in Russia’s newest fast breeder reactor in the Urals, heralding a closed nuclear fuel cycle and a future without nuclear waste. Russia is the only country that operates fast neutron reactors industrially.

The next generation BN-800 breeder reactor (880 megawatts) assembled at Russia’s Beloyarskaya nuclear power plant has been put in the so-called critical state on Friday, a week after all necessary nuclear fuel was loaded into the active zone.

The press service of Rosenergoatom, the electric energy generation branch of Russia’s nuclear monopoly, Rosatom, has confirmed to the RIA news agency that nuclear reaction in the BN-800 reactor has been initiated.

“Starting from that moment the reactor started to ‘live’,” RIA said, quoting the source in Rosenergoatom.

This means that controlled nuclear fission in the reactor is self-sustaining and ongoing at a constant speed. Once this most important stage of the start-up work is done, the reactor will be gradually prepared to achieve the desired 880 megawatts output expected to be reached in October, when the reactor will be commissioned for industrial use.

The BN-800 uses liquid metal sodium (Na) as a coolant heat transfer agent. The start of commercial operation of the new reactor is planned for early 2015.

Service life of the BN-800 breeder reactor is expected to be 45 years. Every month it will produce 475 million kilowatt hours of electricity, enough to ensure constant supply to 3.15 million families (considering that the average monthly consumption of a family of three is 150 kilowatt hours).

Beloyarskaya nuclear power plant is situated in Zarechny, some 45 kilometers from the regional center of Yekaterinburg, in the Urals region.

The fast-neutron nuclear reactors use so-called breeder reactor technology that enables the use of a wider range of radioactive elements as fuel, thus considerably enlarging the potential stock of nuclear fuel for electricity generation.
Fast fission reactors close the question of potentially ending uranium nuclear fuel as they could ‘burn’ even nuclear waste.

Besides producing electric energy, it generates more fissile material that can be used as nuclear fuel. This brings us to the closed nuclear fuel cycle, a long-lasting dream of the nuclear energy industry that appears to have come true.
Unlike ‘traditional’ nuclear reactors that use assemblies of uranium-235 as the principal fuel, breeder reactors use specially designed MOX (Mixed Oxide) fuel based on plutonium-239.

Russia’s nuclear monopoly, Rosatom, is finishing a plant in Krasnoyarsk region that will produce MOX fuel for the BN-800 reactor. The production line is assembled in a mine 200 meters underground. This will be operable by the end of 2014, and, starting from 2016, it will be running at full capacity…………………….http://rt.com/news/168768-russian-fast-breeder-reactor/
