During bombarding of the Tungsten or Uranium targets the electron beam generates the original neutrons that are multiplied in the facility core of low enriched uranium trough the fission process. The maximal value of the neutron multiplication factor is 0.98. So the total neutron flux output is increased as much as 50 times and is 2·10 n·cmc. The subcriticality of the system eliminates the possibility of self-sustained chain reaction existence that increases the nuclear safety of the facility drastically. The neutron source mentioned above is the first facility of such type in the world. The results that will be obtained at studies of neutron characteristics of the neutron source with low enriched uranium core and during optimiza...

The facility consists of a subcritical assembly driven by a 100MeV/100kW electron linear accelerator. The electron beam will be used for generating the neutrons for operating the subcritical assembly using tungsten or natural uranium target. The facility is planned to support the Ukraine nuclear industry, and provide a capability for performing reactor physics, material research, and basic science experiments, to produce medical isotopes, train young nuclear professionals. The integrating facility tests were completed at the end of 2018, and physical start-up operation began in 2019. The facility commissioning and current start-up results are presented and discussed in the paper.

The main functions of the subcritical assembly are support of the nuclear industry and medical researches. Reactor physics and material researches will be carried out at the facility. For subcritical assembly design proven techniques and practices are used to enhance its utilization. The goal of the development is to create in Ukraine the experimental basis for neutron research based on safe intensive sources of neutrons. The main facility components are an electron linear accelerator, a system for electron beam transportation from linear accelerator to the neutron production target, subcritical assembly, biological shield, neutron channels and auxiliary supporting systems.

The proposed technique is based on registration of the object response induced radiation when the object is irradiated by a high-power neutron pulse. Sensitivity of the technique (detection distance) is determined by the illumination source power, and by efficiency and discrimination capability of the induced .emission detectors.
