Construction started on a larger [[BN-800 reactor|BN-800]] type fast breeder reactor in 1987. Protests halted progress in 1988, but work resumed in 1992 following an order by President [[Boris Yeltsin]]. Financial difficulties have resulted in slow progress. Construction costs have been estimated at 1 trillion [[Russian ruble|rubles]] and the new reactor can only be finished in 2012–2015 given current scarce financing. The BN-600 was originally planned to be decommissioned in 2010 but its lifetime is likely to be extended to cover the gap; it has been operating since 1980 years so far.
On 27 June 2014, controlled nuclear fission has been started in the BN-800 fast breeder reactor. The newest reactor helps to close the nuclear fuel cycle and to achieve a fuel cycle without or with less nuclear waste. Russia is, at the date, the only country that operates fast neutron reactors for energy production. The BN-800 has been put in the so-called critical state a week after all necessary nuclear fuel was loaded into the active zone. The reactor will be gradually prepared to achieve the 864 megawatts output, a power level expected to be reached in October, when the reactor will be commissioned for industrial use.
