Abstract
The Frank Laboratory of Neutron Physics of the Joint Institute for Nuclear Research in Dubna (located about 130 km north of Moscow) was created in 1956. The laboratory got its name after the late Professor I.M. Frank, Nobel Prize Laureate and first director of the laboratory. To develop scientific activity in neutron physics, it was decided to construct a pulsed reactor with periodic operation. This idea was realized in 1960, when the first IBR facility was put into operation. The average power of this reactor was just 1 kW, but the power in the pulse reached 5 MW.
