Both were [[supercritical water reactor]]s; the first unit used 67 tons of Uranium enriched to 1.8%, while the second unit used 50 tons of Uranium enriched to 3.0%. The first unit had an indirect steam cycle, while the second had a direct one.<ref name="Kingery2011b">{{cite book|editors=Steven B Krivit; Jay H Lehr; Thomas B Kingery|title=Nuclear Energy Encyclopedia: Science, Technology, and Applications|year=2011|publisher=Wiley|isbn=978-1-118-04347-9|pages=318–319}}</ref>
Although they were comparable in power to the [[Shippingport Atomic Power Station]], the Soviet planners regarded the Beloyarsk reactors as prototypes.<ref name="Josephson2005"/> Their main novelty was the use of superheated steam ran through a standard turbine thus resulting in a better efficiency compared to the earlier [[Obninsk Nuclear Power Plant]] pilot plant. The first Beloyarsk unit produced about 285 &nbsp;MW heat of which about 100 &nbsp;MW were converted to electricity.<ref name="Josephson2005">{{cite book|author=Paul R.

Two reactors are now in operation: a [[BN-600 reactor|BN-600]] [[fast breeder reactor]], generating 600 &nbsp;[[Watt (unit)|MWe]] and a [[BN-800 reactor|BN-800]] [[fast breeder reactor]], generating 880 &nbsp;[[Watt (unit)|MWe]]. The BN-800 is the largest [[fast neutron reactor|fast neutron power reactor]] in service in the world. Three turbines are connected to the BN-600 reactor. The BN-600 reactor core is {{convert|1.03|m|in}} tall and has a diameter of {{convert|2.05|m|in}}. It has 369 [[Nuclear fuel|fuel]] assemblies, each consisting of 127 fuel rods with an enrichment of 17–26% [[Uranium-235|U<sup>235</sup>]]. In comparison, typical enrichment in other Russian reactors is in the range of 3–4% U<sup>235</sup>. BN-600 reactors use liquid [[sodium]] as a coolant. As with most Russian nuclear power plants, the station lacks a [[containment building]].

}}</ref> However issues detected during low power operation required further fuel development work. On 31 July 2015, the unit again achieved minimum controlled power again, at 0.13% of rated power. Commercial operations are expected to start before the end of 2016, now with a power rating of 789 &nbsp;MWe.<ref name=nei-20160114>{{cite news |url= |title=Fast reactor progress at Beloyarsk |publisher=Nuclear Engineering International |date=14 January 2016 |accessdate=19 January 2016}}</ref> In December 2015, Unit 4 was connected to the national grid.<ref>{{cite web
