Ukraine's nuclear watchdog says that a nuclear research facility in Kharkiv again has come under shelling by Russia and the fighting makes it impossible to assess the damage.
The State Nuclear Regulatory Inspectorate said that the neutron source experimental facility in the Kharkiv Institute of Physics and Technology came under fire Saturday.
Ukrainian authorities have previously reported that Russian shelling damaged buildings at the Kharkiv facility, but there has been no release of radiation.
The newly built neutron source facility is intended for the research and production of radioisotopes for medical and industrial needs.
The International Atomic Energy Agency has said that the nuclear material in the facility is always subcritical and the inventory of radioactive material is very low, reducing the risks of radiation release.
Kharkiv has been besieged by Russian forces since the start of the invasion and has come under repeated shelling of its residential buildings and critical infrastructure.
Ukraine's nuclear facilities have been threatened by the Russian invasion.
