The Kursk nuclear power plant ( Russian: Курская АЭС [ listen ^?^/^I ]) is located about 35 kilometers west of the city of Kursk in western Russia , near Kurchatov on the bank of the Seim . The owner and operator of the nuclear power plant is the state-owned company Rosenergoatom .

history

Construction of the first nuclear reactor began on June 1, 1972. The second reactor block followed on January 1, 1973. On December 19, 1976 the first and on January 28, 1979 the second reactor block went into operation. In 1978 and 1981, construction began on reactor blocks three and four, which went into operation on October 17, 1983 and December 2, 1985.

Construction of Unit Five began on December 1, 1985 and should be completed by December 31, 2010. Block 5 belongs to the third generation of RBMK reactors and the physical prototype of the MKER . The 70% completed construction was discontinued in 2012.

A sixth reactor block was under construction; it should be built from 1986 to 2011. Construction stopped after the Chernobyl disaster .

On May 26, 2008, the cooling lake in blocks five and six was completed; it is called Lake Kurchatov 2 .

The four reactor blocks are of the RBMK type . The net power of the reactors in each case is 925 megawatts (MW), the gross power at 1,000 MW. The thermal output is 3,200 MW each. With an installed net total output of 3,700 MW, the nuclear power plant is one of the largest in Russia.

safety

The Kursk 1 and Kursk 2 units built first belong to the first generation of RBMK nuclear reactors. The others belong to the second generation. The safety systems and auxiliary systems in the blocks from the second RBMK-1000 generation are more extensive and improved. All reactors were designed for a period of 30 years. In 2000, the operating license for units 1 and 2 was increased by a further 15 years. According to Rosatom, the upgrading of units 3 and 4 should begin between 2008/09. Block 3 is already being upgraded and will be overhauled.

Kursk II nuclear power plant

The Kursk II nuclear power plant is to be the successor to the current nuclear power plant and is to be built at the same location. Four reactors of the type WWER-1300/510 in the design of the AES-2006 are planned . The net output of each of the new blocks will be 1115 megawatts, the gross output 1255 megawatts. Construction of the foundation of the first block officially began on June 15, 2016 with the pouring of the first concrete. The commissioning of the first reactor is planned for 2021 or 2022.

Data of the reactor blocks

The Kursk nuclear power plant has four operating units , one unit whose construction has been discontinued, one rejected unit and one unit in the planning stage:
