The SNRIU continues providing information on the state of the Chornobyl NPP.
From the very beginning of the Russian military aggression against Ukraine, all Chornobyl NPP facilities, and facilities located in the Exclusion Zone are under the control of the country's military aggressor. For 24 days in a row, the Chornobyl NPP personnel has been courageously and heroically performing their functions without rotation to ensure the safe operation of these facilities.
Given the psychological, moral, and physical fatigue of the personnel, as well as the absence of day-time and repair staff, maintenance and repair activities of equipment important to the safety of the facilities located at the Chornobyl NPP site are not carried out, which may lead to the reduction of its reliability, and result in equipment failures, emergencies, and accidents.
The regulatory control over the state of nuclear and radiation safety at the Chornobyl NPP site and in the Exclusion Zone, as well as control over nuclear materials at the enterprise is currently impossible to exercise.
The SNRIU has established communication channels with the Chornobyl NPP with the on-site personnel through the ChNPP management in Slavutych. Information on the main performance indicators of the Chornobyl NPP on-site facilities and the operational state of the radiation situation at the NPP site was received on 19 March 2022.
According to the information received, the controlled parameters of the Shelter, gamma radiation dose rate, and neutron flux density in the reactor premises of the destroyed unit 4 do not exceed the operating limits set by the process procedures for the safe operation of the New Safe Confinement-Shelter. The radiation situation parameters at the Chornobyl NPP site (based on the available measurement results) do not exceed their reference levels. In the absence of readings from the radiation situation monitoring system RADOS, data are obtained by measurements performed by the ChNPP operational personnel using portable devices at the locations of the exposure dose rate sensor RADOS. Certain monitoring points are not available for measurement by portable devices.
