Nuclear Power Plants in the Czech & Slovak Republics
Bohunice-A1
Location: Slovakia
Operator: Slovenske Elektrarne
Configuration: 3 X 50 MW GCR
Operation: 1972-1977
Reactor supplier: Skoda
T/G supplier: Skoda
EPC: Skoda
Quick facts: In 1956, the Czechoslovak government began development of its first NPP, the KS-150 gas-cooled, heavy water, pressure-tube reactor at Bohunice. This is a unique reactor, desiged in the USSR and built by Skoda. The A1 reactor was completed in 1972 and ran until 1977 when it was closed due to a serious refueling accident. The plant is being decommissioned by Jadrova a vyradovacia spolocnost as.

Bohunice
Location: Slovakia
Operator: Slovenske Elektrarne
Configuration: 4 X 440 MW PWR
Operation: 1979-1986
Reactor supplier: AEE, Skoda
T/G supplier: Skoda
Quick facts: Preliminary construction of the so-called V1 plant at Bohunice with two VVER 440/V 230 units started on 24 Apr 1972 and, one year later, full construction got underway. The first unit went critical on 27 Nov 1978 and began test operation on 17 Dec 1978. The second unit started up on 15 Mar 1980 and was put into test operation on 26 Mar 1980. On 31 Dec 2008, Slovakia decommissioned the second reactor at Jaslovske Bohunice to comply with its EU-accession agreement. Unit-1 having been taken offline in 2006. JAVYS will now undertake full dismantling of both reactors, a job that will take until 2025 and cost Sk40bn..

Dukovany
Location: Czech Republic
Operator: CEZ AS
Configuration: 4 X 440 MW PWR
Operation: 1985-1988
Reactor supplier: AEE
T/G supplier: Skoda
Quick facts: In 2000, a $240mn, 9yr modernization program was launched for these VVER-440/213 reactors. This included two modules, one for reactor control and protection and one for IT. The work on Unit-1 was completed in May 2005 in time for the 20th Anniversary of plant operation. It represented one of the largest I&C modernization efforts ever undertaken by contractors Skoda, Framatome, ZAT, and I&C Energo. In 2008, Dukovany set an all-time site record output of 14,450 GWh. In part this was due to unit uprating to 462 MW (Units 2-4) and 468 MW (Unit-1).

Mochovce
Location: Slovakia
Operator: Slovenske Elektrarne
Configuration: 2 X 440 MW PWR
Operation: 1999-2000
Reactor supplier: AEE
T/G supplier: Skoda
Quick facts: Construction on two more units was halted in 1992 while SE concentrated on completion of the first two sets. Work was re-started on Units 3&4 in Nov 2008. SE plans to invest 2.77bn to finish the units in 2012 and 2013, respectively.

Temelin
Location: Czech Republic
Operator: CEZ AS
Configuration: 2 X 1,000 MW PWR
Operation: 2002-2003
Reactor supplier: Skoda
T/G supplier: Skoda
EPC: Energoprojekt Prague, Skoda
Quick facts: In 1980, the government decided to build four VVER-1000 units at a large site in southern Bohemia 100km from Prague and 60km from the Austrian border. Initial design began in 1985 and major construction started in 1987. In 1990, an OSART evaluation mission was dispatched in 1990 by IAEA which recommended a program to upgrade the reactors to Western standards. In 1990, the government decided to stop construction on Temelin 3&4 after new demand forecasts. In Mar 1993, the Czech Republic decided to complete Units 1&2, budgeted for fully 25% of CEZ's capex during 1994-2000. In May 1993, Westinghouse received contracts for I&C upgrades and for fuel fabrication and reloads. In Jun 1995, CEZ and Skoda signed a completion agreement and the government gave final approval in 1999 stipulating that the final capital cost would not exceed K98.6bn (around $3.3bn). Fuel was loaded in Unit-1 in Jun 2000 and the reactor went critical in Oct, reaching 90% power in Dec. A variety of technical problems mostly turbine-related - delayed full-time operation until Jun 2002. The second unit was authorized for fuel load in Mar 2002 and went to full power in 2003. Both reactors were declared in commercial service in Oct 2004. The plant had a record production year in 2012 recording 15,302 GWh of output.
