The operator of the Novovoronezh nuclear power station in central Russia has shown a commitment to improving operational safety, but the quality of maintenance activities needs to be further improved, an International Atomic Energy Agency (IAEA) team said.
The team also called on the operator to enhance the consistent use of tools to minimise human error and to improve arrangements for the monitoring and reporting of equipment condition and material deficiencies to ensure that any degradation is identified and reported.
The team identified one good practice to be shared with the nuclear industry globally: the main control room operators at Novovoronezh have access to an electronic display for real-time indication of hydrogen ignition risk inside the containment building in the case of a severe accident.
