The USSR-Russia Fast-Neutron Reactor ProgramThe BR-2 was replaced with <strong>the</strong> BR-5 (5 MWt), 7 and commenced operations in1959. It was cooled with liquid sodium and fueled with plutonium dioxide toallow higher fuel temperatures and power densities (up to 500 kilowatts/liter)in <strong>the</strong> core. 8 The BR-5’s power was subsequently increased to 10 megawatt<strong>the</strong>rmal (MWt) and it operated until 2004. In addition to reactor research anddevelopment, <strong>the</strong> BR-5 was used <strong>for</strong> medical-isotope production and even medicaltreatment (neutron-capture <strong>the</strong>rapy <strong>of</strong> throat cancer using neutron beams from<strong>the</strong> reactor).Second and third decades, 1960-80During <strong>the</strong> second and third decades <strong>of</strong> <strong>the</strong> program, experience was acquired in<strong>the</strong> use <strong>of</strong> fast-reactor technology.In 1961, <strong>the</strong> critical assembly BFS–1 started operation at IPPE. It allowedresearchers to simulate fast-reactor core volumes <strong>of</strong> up to 3 m 3 with cores fueledby different mixtures <strong>of</strong> plutonium and uranium <strong>of</strong> varying enrichments, anddifferent configurations <strong>of</strong> control and safety rods. It also allowed studies <strong>of</strong> <strong>the</strong>effects <strong>of</strong> sodium voids on reactivity and o<strong>the</strong>r physical effects. BFS-2, whichstarted operating at IPPE at <strong>the</strong> end <strong>of</strong> <strong>the</strong> 1960s, could simulate cores withvolumes up to 10 m 3 .A higher power special fuel-testing reactor, <strong>the</strong> BOR-60, was designed andconstructed in <strong>the</strong> Institute <strong>of</strong> Atomic Reactors (Dimitrovgrad) in five years andbegan operating in 1969. Vibro-packed fuel was tested in this reactor. It is stilloperational.Between 1962-1964, <strong>the</strong> future direction <strong>of</strong> Soviet nuclear energy developmentwas studied. A main concern was conservation <strong>of</strong> uranium resources. The studyconcluded that a “promising perspective is expansion <strong>of</strong> nuclear energy using fastbreeder reactors starting with enriched uranium fuel and step-by-step replacementwith plutonium fuel.”A demonstration project was initiated even be<strong>for</strong>e <strong>the</strong> BR-5 began operating.Initially <strong>the</strong> demonstration reactor was named BN-50 (50 MWt) but later <strong>the</strong>power was increased to 1000 MWt. The reactor came to be called BN-350 <strong>for</strong>its equivalent electrical output. 9 The design <strong>of</strong> <strong>the</strong> demonstration BN-350 and asignificant number <strong>of</strong> experiments at <strong>the</strong> BFS-1 critical assembly were completedbe<strong>for</strong>e construction started in 1964. 10 The Minister <strong>of</strong> Atomic Energy, Yefim P.Slavsky, decided to build <strong>the</strong> reactor on <strong>the</strong> Mangyshlak peninsula on <strong>the</strong> CaspianSea. The heat was used <strong>for</strong> desalination as well as electricity generation. It wasfueled with uranium enriched up to 20-25 percent uranium-235 and with mixedoxideuranium-plutonium (MOX) test fuel assemblies. It began operations in1972.64
