Nuclear Power Plant Kozloduy

Location

• NPP Kozloduy is located 200 km north of the Bulgarian capital on the Danube River,near the town of Vratsa.

• Production facilities are located in an area of about 1000 acres. The infrastructure of NPP "Kozloduy" includes the private bank pump station and channels for technical water supply to which the total area of the power plant is estimated at 4,471 acres.

History

• Kozloduy nuclear power plant is the first nuclear power plant in Bulgaria and south-eastern Europe. The beginning of the nuclear power engineering was laid on 15 July 1966 by signing the agreement for cooperation between Bulgaria and former Soviet Union for the construction of a nuclear power plant.

• Some completely Bulgarian projects have been implemented for the first time in the world practice in the construction of nuclear power plants. Some of these technical solutions are significant engineering achievements foreign specialists have been interested in. The construction of the main building of Kozloduy NPP started on 6 April 1970 -240 m long, 105 m wide and 40 m high. On 20 th November 1972 the first reactor was installed into the reactor cavity.

Technological scheme of the NPP with water-energy reactor

• The principle scheme of the NPP with water-water power reactor is dual-core. This solution is advantageous from the viewpoint of non-radioactive substances, since there is no mixing of the water from the two circuits. All the equipment for the first loop is placed in a sealed volume, which by means of the exhaust ventilation is maintained at a pressure lower than atmospheric pressure.

• Safety is the main priority at Kozloduy NPP and it is a subject to independent state surveillance by the Nuclear Regulatory Agency at the Bulgarian Council of Ministers. Kozloduy NPP safety has been highly assessed and acknowledged internationally as a result of the reviews conducted in the last years.

• The electricity generation of Kozloduy NPP entirely fits into the World Nuclear Association’s concept of nuclear renaissance. The company meets the high environmental requirements of the Kyoto Protocol for it does not release any greenhouse gasses into the atmosphere and it does not pollute The Danube river.
