The Dampierre Nuclear Power Plant is located in the French commune of Dampierre-en-Burly in the Region Center-Val de Loire in the department of Loiret . The nuclear power plant , which consists of four pressurized water reactors , is located about 55 kilometers east of the city of Orléans on the banks of the Loire .

Key data

Electricity production of the individual units of the nuclear power plant since commissioning

The 120 hectare nuclear power plant area employs around 1250 people. The operator of the nuclear power plant is the French company Électricité de France (EDF). The cooling of the reactor blocks is carried out using four cooling towers and the water taken from the Loire.

The four pressurized water reactors have a net capacity of each 890  megawatts (MW) and a gross capacity of 937 MW. The total installed capacity is 3748 MW, making the nuclear power plant one of the larger in France. It feeds an average of 23 billion kilowatt hours into the public power grid every year . This corresponds to about seven times the annual electricity consumption of the Loiret region and five percent of the annual electrical energy generated by the operator EDF.

Construction of the first reactor block began on February 1, 1975; In the same year construction began on the three other reactor blocks. The first block went into operation on March 23, 1980; the last reactor block was commissioned on January 30, 1981. The shutdown of the reactors is planned for 2020 and 2021.

safety

In the event of a strong earthquake , the emergency cooling could fail. According to a report by the atomic safety authority ASN in October 2002, certain protective functions that ensure that the reactor blocks cool down could no longer be guaranteed in the event of an earthquake. This is a safety-relevant valve whose functionality is at risk in the event of an earthquake.

On April 9, 2007, an incident similar to that in the Forsmark nuclear power plant occurred in Unit 3 of the nuclear power plant . A defect in an overvoltage protection relay led to the power station being disconnected from the main power grid. In order to dissipate the inevitable, risk-relevant decay heat with pumps after the reactor has been shut down , a switchover to the reserve power grid would have had to take place, but this did not happen. This resulted in an emergency power failure (total external power failure ). In the case of one of the two properly run-up emergency diesel generators, each with 100% capacity, the connection to the assigned busbar did not succeed, so that the power supply could only be guaranteed by a single power-driven emergency power train. There were potentially two further redundancies available for emergencies: a self-steam driven pump, which would have been operational more or less immediately, and a power-generating gas turbine , which, according to the Institut de Radioprotection et de Sûreté Nucléaire, would not have been immediately available, but one needs a certain start-up time. Due to the serious situation, the on -site emergency plan was triggered. It took ten hours to restore external power from the grid.
