On the 60th anniversary of the first aperiodic pulsed nuclear reactor in Russia

The article describes the history of creating the first Russian nuclear reactor capable of generating powerful controlled fission pulses. The FKBN‑I reactor was launched in 1964 at NII-1011 (currently FSUE “RFNC—VNIITF named after Academ. E.I. Zababakhin”). Forming the basis of FKBN‑I, pioneering work was carried out on the experimental development of technical solutions and control modes, which were used for the design of aperiodic pulsed reactors. The main neutron-physical characteristics and parameters of first fission pulses are given along with a description of methods for obtaining them. The article also mentions the main developers and researchers involved in the creation of the reactor.
