Doel-4 Nuclear Power Plant, Belgium
The Doel nuclear power plant (in Dutch: Kerncentrale Doel) is in the territory of Doel (the municipality of Beveren), on the left bank of the Scheldt in Belgium. It is located 25 km north of Antwerp, 42 km north-west of Brussels and 136 km south-southeast of Amsterdam (line all distances).
- Doel 1 412 MWe, commissioned in 1974 for 40 years.
- Doel. 2: 454 MWe, put into service in 1975 for 40 years.
- Doel 3: 1056 MWe, commissioned in 1982 for 40 years.
- Doel 4: 1 041 MWe, commissioned in 1985 for 40 years.
Representing a total installed capacity of 2,963 MW.
The Doel 1 and 2 reactors should have been stopped in 2015, although the duration of operation was extended for 10 years on December 18, 2014 in the federal government (Government Michel) 1; Doel 3 Doel in 2022 and 4 in 2025.
The Doel nuclear power provides about 30% of electricity consumption in Belgium. In early 2011, the plant has 940 employees working, of which 800 work at the core of reacor. Doel nuclear power occupies about 80 hectares.
Incidents of Doel Nuclear Power Station
Incidents are classified according to the INES scale. This scale has eight levels of severity rated from 0 to 7. Level 0 incidents incidents are not always made public. There has never been a nuclear incidents or accidents higher level to 2 on the Doel nuclear power.
In May 2012, an anomaly was detected in a valve in the No. 2 reactor shutdown for annual maintenance. The incident was classified at the first level on the INES scale.
In August 2012 it was revealed that 1,000 defects were detected in July of the same year, in the No. 3 reactor vessel, during ultrasonic control of all highly irradiated area of the vessel. These defects whose origin to this day is not known precisely due to manufacturing defects and "could equate to potential cracks" in the words of the Belgian Federal Agency for Nuclear Control (FANC). The director of the FANC, told French public radio (RTBF) on the possibility of reusing the reactor vessel after the discovery of anomalies, he said it was "very skeptical". If the first results of the survey are confirmed, and as the vessel of a reactor can not be replaced, this incident could result in the closure of the reactor number 3, which inevitably have a major impact on energy supply Belgian consumers.
However, the Belgian Nuclear Safety Authority issued during 2013 May, a decree authorizing the operator to restart in two installments of 1 000 MW. Indeed, detailed studies have revealed that the "cracks" detected in 2012 through more precise techniques that are before there from the original forged and do not evolve. The operator expects to restart before the end of June.
Tuesday August 5, 2014, the morning of the 65 000 liters of oil required for operation of the steam turbine connected to the reactor No. 4 was poured into an underground reservoir for this purpose in the case of fire, leading to resulted in the arrest Doel nuclear plant. It is believed that the action was carried out deliberately with a criminal motivation. It closed on Friday, December 19, 2014 after repair damaged, for now, the reactor 4 has not gone to launch turbine.
Temporary closure of the nuclear reactor Doel 3
In August 2012, 8000 microcracks were found in the reactor vessel 3 of the Doel nuclear plant. In March 2014, the reactor is turned off. In February 2015, new analysis by Electrabel still revealed more cracks than in 2012. Electricity production Doel 3 reactor restarted in January 2016.
