The nuclear power plant Civaux is located in the French city of Civaux in Vienne, in the region Nouvelle-Aquitaine . It has two pressurized water reactors of the type N4 and is located 34 kilometers southeast of Poitiers on the left bank of the Vienne , a tributary of the Loire . The operator is the French company Électricité de France (EDF).
Key data
Around 700 people are employed in the 220 hectare nuclear power plant area. The reactor blocks are cooled with two cooling towers and the water taken from the Vienne.
The two pressurized water reactors of the type N4 provided the basis for the development of the EPR . The reactors were to the year 2018 with a net capacity of each 1,495 megawatts (MW) and a gross capacity of 1,561 MW, the most powerful reactors in the world. The total installed capacity is 3122 MW, making the nuclear power plant one of the medium-sized ones in France. The power plant feeds an average of 18 billion kilowatt hours into the public power grid every year .
The two cooling towers of the nuclear power plant are 180 meters high, making them the highest in France.
Construction of the first reactor block began on October 1, 1988; it went into operation on December 24, 1997. Construction of the second reactor block began on April 30, 1991 and was completed on December 24, 1999. Unit 1 became critical for the first time on November 29, 1997 , and Unit 2 on November 27, 1999. The shutdown of the reactors is planned for 2037 and 2039 .
safety
On May 12, 1998, a nuclear incident occurred in which a crack 18 centimeters long and 2.5 centimeters wide appeared in a cooling circuit of the first reactor. According to the authorities, 30 m³ of water per hour leaked through this crack . The leak could only be located after almost 10 hours and the leaky water circuit shut off. Cooling until the leak was repaired could be ensured with the second water circuit. The incident has been classified by the French nuclear regulatory authority ASN with level 2 on the International Rating Scale for Nuclear Events (INES).
On October 18, 2016, the ASN announced that within three months, EDF had to perform an unscheduled check of the functionality of steam generators on five nuclear reactors that were currently running, one of these five was reactor I in Civaux.
Data of the reactor blocks
The Civaux nuclear power plant has two blocks :
Reactor block | Reactor type | net power |
gross power |
start of building | Network synchronization |
Commercialization of essential operation |
switching off processing |
---|---|---|---|---|---|---|---|
Civaux-1 | Pressurized water reactor | 1495 MW | 1561 MW | October 15, 1988 | 12/24/1997 | 01/29/2002 | (Planned for 2037) |
Civaux-2 | Pressurized water reactor | 1495 MW | 1561 MW | 04/01/1991 | 12/24/1999 | 04/23/2002 | (Planned for 2039) |
Passenger transportation
Starting in April 2016, six fully autonomous electric shuttle buses from the manufacturer Navya will be used for the first time for passenger transport on the 220 hectare site of the power plant, on which up to 1100 people work . It is operated in partnership with the operator Transdev and replaces traditional diesel buses.
