We remind you, that as a result of the military attack of the Russian Federation on Ukraine from the territory of the Republic of Belarus, starting at 05:00 on 24 February 2022, all facilities of the Chornobyl NPP located in the Exclusion Zone, such as ChNPP units 1-3 (at the decommissioning stage), spent nuclear fuel storage facilities (ISF-1, ISF-2), New Safe Confinement of the Shelter, facilities designed for radioactive waste management, continue to be under the control of the aggressor country.
It has been eleven days since the Chornobyl NPP personnel courageously and heroically perform their functions without rotation to ensure the safe operation of these facilities.
Operation of the automated radiation monitoring system of the Exclusion Zone has not been restored. Regulatory control over the state of nuclear and radiation safety of nuclear facilities and other facilities located at the Chornobyl site and in the Exclusion Zone is currently impossible to exercise.
Stationary and cellular telephone communication with the Chornobyl NPP personnel, which remains directly at the NPP, has not been restored. We remind you, that the loss of telephone communication is a consequence of the military attack and seizure of the enterprise by the military troops of the Russian Federation.
According to the information received from the Chornobyl NPP personnel through available communication channels, safety parameters of the Chornobyl NPP facilities are still within the standard limits.
At the same time, according to the information available in the SNRIU, several neutron flux sensors, and sensors to monitor gamma radiation dose rate and radiation contamination in the air at the Shelter, are out of order, which made it impossible to monitor the criticality and a number of radiation parameters in one of the Shelter premises. Due to the lack of sufficient number of the repair personnel and special equipment due to the occupation, the repair of damaged equipment of the systems important to nuclear and radiation safety is not performed.
Safety parameters data indicate a deteriorating trend in a number of indicators, in particular, it is concentration of long-lived radionuclides in the atmosphere. The occupier seriously violates the radiation safety requirements and strict access control procedure at the enterprise and in the Exclusion Zone. In particular, the aggressor neglects the requirements for the mandatory use of air locks, changing of clothing and footwear when visiting “dirty” areas of the enterprise, decontamination, undertakes uncontrolled movement of military personnel and military equipment at the enterprise, in the Exclusion Zone and beyond its boundaries. This, in turn, leads to deterioration of the radiation situation at the facility and in the Exclusion Zone, as well as contributes to the spread of radioactive contamination outside the Chornobyl Exclusion Zone.
The SNRIU continues monitoring the situation at the Chornobyl NPP facilities and analyzing data obtained from available information sources.
