Decommissioning experience
This nuclear plant marks the first decommissioning of a complete nuclear power station in France. EDF and CEA announced their intention to make this a transparent process so that it can be used as a model for future decommissioning operations at other plants.
The process is divided into 3 stages.
Stage 1
This stage began in 1985, and is similar to a
- final shut-down
- discharge of the nuclear fuel
- draining of cooling circuits
Stage 2
In 1995, a public inquiry was held. In 1996, it was decided that a feasibility study for the "greening" of the site would be submitted by the end of 1999. Stage 2 began in 1997, consisting of:
- decontamination and disassembling of the buildings except for the reactor itself
- evacuation of the nuclear waste
- containment of the reactor pressure vessel
On December 13, 2000, a rise in the ground water level caused a flood in the chemical processing building. In January 2001, a fire broke out in the joint inner building. In 2005, stage 2 was officially complete.
Stage 3
Stage 3 consists mostly of containing the reactor pressure vessel (RPV) and is underway. The full decommission is planned to be finally totally complete in year 2040.
- dismantling of the steam generators
- dismantling of the reactor pressure vessel
- demolition of the containment building
