The Dukovany Nuclear Power Station

The Dukovany Nuclear Power Station is a nuclear power plant (NPP) near Dukovany, a village in the Czech Republic.

It was the first NPP in what is now the Czech Republic (the Bohunice Nuclear Power Plant in what is now Slovakia was constructed in 1958) and is situated 30 kilometres (19 mi) from the city of Třebíč, near the Dalešice Reservoir, where the NPP sources its water supply. In 1970 Czechoslovakia and the Soviet Union ratified a contract for construction of two NPPs. Actual construction work began four years later. From 1985 to 1987, four power units with pressurized water reactors were commissioned. All four are still in operation.

In 1994, a tourist centre was opened at the site.

Dukovany NPP annually supplies approximately 14 TWhr of electric energy to the national power network.[1] NPP is owned and operated by CEZ Group. The power plant modernisation will successively be carried out to the end of its planned service life.[1]

Technical data

The Dukovany NPP has four reactors. As of December 31, 2011 CEZ reported turbine generator output (gross capacity) as listed below. Net capacity is a baseline estimate only.

Unit Type Net capacity Gross capacity Initial criticality Grid date
1VVER-440/213471 MWe505 MWeFeb 1985Aug 1985
2VVER-440/213471 MWe505 MWeJan 1986Sep 1986
3VVER-440/213471 MWe505 MWeOct 1986May 1987
4VVER-440/213471 MWe505 MWeJun 1987Dec 1987

In 2005, Unit 3 was upgraded to 456 MWe gross capacity, and the same upgrade was made to Unit 1 and Unit 4 in 2007. Unit 3 was further upgraded in 2009 to 500MWe. In total an extra 240 MWe of capacity has been or will be added before 2013 in a comprehensive program of improvements including steam plant replacement, addition of instrumentation and fuel changes.

The reactors are fuelled by uranium dioxide UO2. Fuel is placed in the reactor in 312 fuel assemblies. Each assembly consists of 126 fuel rods with a hermetically sealed fuel.

Cooling Towers

Dukovany Nuclear Power Station has 8 cooling towers, each 125 metres tall.

Meteorological Tower

West of the facility at 49°5'42.89"N, 16°8'5.44"E, there is a 136 metre tall guyed tower for monitoring air radioactivity.

Power distribution

The powerlines leaving Dukovany Nuclear Power Station are mainly installed on delta type pylons. They run to Slavetice substation situated at 49°6'15" N and 16°7'10" E. At this substation the powerline to Dürnrohr in Austria starts.

Plant owner CEZ plans to install a district heating circuit to supply heat to homes and businesses in Brno. A pipeline over 40 kilometres in length could be installed after regional officials have considered CEZ's environmental impact statement for the project, submitted in July 2010.

The Dukovany reactor complex appears in the video game Tom Clancy's EndWar as a potential battlefield.[2]
