The environment protection control is carried out through a number of measures related to the environment monitoring; monitoring of the NPP releases in the atmosphere and the hydrosphere; processing and storing of radioactive and conventional waste. The continuous radiation monitoring in the 3 km zone is performed by the plant Automated Information System that is integrated in the analogical National System.

Samples from air, soil, vegetation, the Danube river and drinking water sources are taken and analyzed in the 100 km control area around Kozloduy NPP, the radiation gamma background is measured as well.

The radiological indicators of the ecological components are within the typical for the region range of values.
