LARGE-SCALE PROJECTS

Drainage of the facilities of the areva mox fuel fabrication plant, Cadarache

With over 20 years of experience in the clean-up and dismantling of its own sites, AREVA is currently working on 4 major worksites at its own facilities and those of CEA.

LA HAGUE: DISMANTLING FIRST GENERATION FACILITIES

The first industrial recycling plant at AREVA's La Hague site, UP2 400, was shut down at the end of 2003 and replaced by 2 new plants.

During its operation, UP2 200 processed:

  • almost 5,000 tons of fuel for graphite-gas power plants,
  • almost 4,550 tons of fuel for pressurized water power plants,
  • fuel originating in rapid neutron reactors. 

The dismantling operations include the clean-up of all facilities, and also the conditioning of waste, as suitable procedures were not available at the time.

This extremely large worksite, begun in 2009, should be operational for 25 years. La Hague represents: 4 billion euros over 25 years, and up to 500 people on the worksite.

MARCOULE: THE FIRST DISMANTLING OF A RECYCLING PLANT

The dismantling of the UP1 plant at the Marcoule nuclear study center is a peerless benchmark for the world.

From 1958 to 1997, UP1 treated fuel for Defense, then for the graphite - gas program (UNGG).

Started ten years ago by AREVA, the worksite should still last for another ten years. Since 2005, AREVA has led the operation as the project owner on behalf of CEA.

A number of remotely controlled, chemical decontamination and cutting techniques were developed for this worksite. A specialist facility also enables onsite waste processing and conditioning (rubble, scrap metal, bitumen drums, etc). This reclamation project constitutes a world first for a nuclear site of this size.

Marcoule represents: 5.6 billion euros over 30 years, and up to 250 people on the worksite.

CADARACHE: THE FIRST DISMANTLING OF A MOX PLANT

From 1962 to 2003, the Cadarache plant first produced fuel for the rapid neutron process, then MOX fuel for light water reactors.

Clean-up operations started in 2007, with the assistance of the facility's operational staff. The first phase consists of dismantling, among other things, 432 glove boxes and 44 tanks, which amounts to 600,000 man-hours. The workshops then need to be cleaned and transferred to CEA ownership in 2013.

Cadarache represents: 120 million euros over 6 years, and up to 225 people on the worksite.

ANNECY AND VEUREY: REINDUSTRIALIZING OLD SITES IN AN URBAN AREA

AREVA is carrying out value development operations at Annecy and Veurey, near Grenoble, on 2 industrial sites created in 1955 and 1957 for the production of natural uranium fuel.
The challenge with this project resides in the conversion of a site that no longer has a nuclear purpose. A partnership with local stakeholders and the public authorities has been set up to continue ongoing redevelopment activities and to organize new ones, helping  to maintain jobs at these sites, which are scheduled for decommissioning in 2011 following a public inquiry.

ANNECY/VEUREY represents 60 million euros over 5 years, and 100 people on the worksites.
