The planned annual maintenance of the sixth unit of the Kozloduy Nuclear Power Plant begins, which will be of crucial importance for the country's energy stability. The maintenance, which is planned to last until the beginning of December, will put the current energy capacity of Bulgaria in question.

During this period, when the facility will be shut down, a comprehensive inspection and technical service of the systems will be carried out. The aim is to ensure the safe and reliable operation of the energy unit in the future. On site, the teams are busy with precise work, subject to strict safety procedures, to guarantee the impeccable functioning of the key energy source.

Simultaneously with these activities, the planned measures related to the long-term operation of the unit will be implemented. This is a key moment for ensuring the continuous operation of the Kozloduy Nuclear Power Plant. The reactor of the sixth unit will be refueled with fresh nuclear fuel, which is essential for maintaining the energy flow. This operation is expected to be carried out in compliance with all necessary safety standards, ensuring both the efficiency and the safety of the energy process.

All this is happening against the background of increased international requirements and regulations in the field of nuclear energy. The on-site teams are subject to additional checks and assessments to ensure compliance with the latest safety standards.
