In May 2007 Areva NC announced plans for a new conversion project - Comurhex II - expanding and modernising the facilities at Malvesi and Pierrelatte near Tricastin to strengthen its global position in the front end of the fuel cycle. The EUR 610 million project will increase capacity to15,000 tU/yr from the end of 2013, with scope for increase to 21,000 tU/yr. Work has started at both sites, with major construction being at Malvesi, and first production from new and refurbished facilities is expected in 2012.
In January 2009 EdF awarded a long-term conversion contract to Areva.  From 2012 this will be filled from the Comurhex II plant.
Areva has undertaken deconversion of enrichment tails at Pierrelatte since the 1980s. Its 20,000 t/yr W2 plant produces aqueous HF which is recycled, and the depleted uranium is stored long-term as chemically stable U3O8.
Enrichment:
For 30 years this has been at Eurodif's 1978 Georges Besse I plant at Tricastin nearby, with 10.8 million SWU capacity (enough to supply some 81,000 MWe of generating capacity - about one third more than France's total).  Eurodif has been by far the largest single electricity consumer in France.  It will run at no more than two thirds capacity (using 900-2000 MWe) until the end of 2012 and then close down, as replacement capacity at Georges Besse II is commissioned.
In 2003 Areva agreed to buy a 50% stake in Urenco's Enrichment Technology Company (ETC), which comprises all its centrifuge R&D, design and manufacturing activities. The deal will enable Areva to use Urenco/ETC technology to replace its inefficient Eurodif gas diffusion enrichment plant at Tricastin.  The final agreement after approval by the four governments involved was signed in mid 2006.
The new Georges Besse II enrichment plant at Tricastin was officially opened in December 2010 and commenced commercial operation in April 2011. The EUR 3 billion two-unit plant, with nominal annual capacity of 7.5 million SWU (with potential for increase to 11 million SWU), was built and is operated by Areva NC subsidiary Societe d'Enrichissement du Tricastin (SET). The first stages of the south unit started construction in 2007 and is expected to reach full capacity of 4.3 million SWU/yr in 2015. Construction of the second (north) unit began in 2009 with first production due in 2012 and to be fully operational in 2016 with 3.2 million SWU/yr capacity. Most production from these is contracted as of 2011.
Minority stakes in SET are being offered to customers, and Suez took up 5% in 2008. In March 2009 two Japanese companies, Kansai and Sojitz Corp, jointly took up 2.5%, in June 2009 Korea Hydro & Nuclear Power took a further 2.5%, and in November 2010 Kyushu Electric Power and Tohoku Electric Power each took 1%. The 4.5% Japanese holdings are grouped as Japan France Enrichment Investing Co. (JFEI).   EdF as principal customer opted for a long-term contract instead, and in February 2009 it signed a EUR 5 billion long-term enrichment contract with Areva.  It runs over 17 years to 2025, corresponding with the amortisation of the new plant.  Korea Hydro and Nuclear Power (KHNP) in mid 2007 signed a long-term enrichment supply contract of over EUR 1 billion - described at that time as Areva's largest enrichment contract outside France.
