On the evening of March 10, 2022, the Russian aggressor bombarded a nuclear research facility—a nuclear subcritical facility of the nuclear steam supply system (NSSS) "On-site Neutron Source" of the center Kharkov Institute of Physics and Technology (KIPT).
NSSS "Neutron Source" is completely de-energized, there is superficial damage to the building, according to the State Nuclear Regulatory Inspectorate.
Before the Russian aggression, the NSSS "Neutron Source" was at the stage of physical launch, during which the core was loaded with fresh nuclear fuel. On February 24, 2022, the operating personnel of the NSSS "Neutron Source" switched the facility to a deep subcritical state.
Recall that on March 6, 2022, the NSSS "Neutron Source" was bombed for the first time. This resulted in the following damage:
- the 0.4 kV distribution substation was completely destroyed;
- the cables of the air conditioners of the linear electron accelerator cooling system were damaged;
- in some places there is superficial damage to the main building of the facility;
- the heating main to the complex of buildings and structures of the NSSS "Neutron Source" was damaged;
- windows were broken in the building of the pumping station and cooling towers, as well as in the isotope laboratory.
The NSSS "Neutron Source" is being established on the basis of the NSC KIPT in accordance with the agreements at the Washington Summit. The principles are set out in the Joint Statement of the Presidents of Ukraine and the United States in April 2010, and the Memorandum of Understanding between the governments of Ukraine and the United States on cooperation in nuclear security matters of September 26, 2011. The project is being implemented with the support of the US Argonne National Laboratory.
NSSS "Neutron Source" is intended for scientific and applied research in the field of nuclear physics, radiation materials science, biology, chemistry, and for the production of medical radioisotopes.
