In the period from 24 February to 31 March 2022, all Chornobyl NPP facilities and facilities located in the Exclusion Zone were seized by military units of the russian federation.
As you know, on 31 March 2022 at about 20:00, the russian occupiers left the territory of the Chornobyl NPP site.
As of 08 April 2022, the situation at the Chornobyl NPP site is as follows.
Physical protection of the Chornobyl NPP site is ensured by the National Guards of Ukraine.
The operating organization (Chornobyl NPP) ensures the nuclear and radiation safety of the facilities located at the Chornobyl NPP site.
Despite the increase in the level of radioactive contamination of the Chornobyl NPP site and the Exclusion Zone due to non-conformity with requirements of the radiation safety and strict access procedures, the radiation situation at the site and the equipment parameters monitored by the ChNPP operational personnel are within the limits set by relevant process procedures of nuclear installations and facilities designed for the Radwaste management.
Information on the on-site situation is received by the SNRIU from the Chornobyl NPP management, which is located in Slavutych city.
Day-time and repair personnel, as well as personnel of contractors, are still absent at the ChNPP site. Scheduled activities, implementation of maintenance, and repair measures of systems and equipment of the Chornobyl NPP facilities to be performed by day-time personnel are not carried out since 24 February 2022. In addition, the activities to be performed with the involvement of contracting organizations are not carried out. This situation has already made it impossible to restore the operation of individual neutron flux sensors, gamma radiation dose rate, and air contamination sensors, and may further lead to the failure of other systems and components important to safety. The inoperability of the equipment complicates performing comprehensive monitoring of the criticality and a number of radiation parameters in one of the Shelter premises.
As of now, the main efforts of the ChNPP management are aimed at ensuring the rotation of the ChNPP operational personnel and finding opportunities to send day-time and repair personnel to the site.
The SNRIU is continuously implementing measures to gradually restore regulatory control over the state of nuclear and radiation safety at the Chornobyl NPP site and in the Exclusion Zone territory.
