Orano Cycle, formerlyCOGEMA (Compagnie générale des matières nucléaires) andAreva NC, is a French nuclear fuel company. It is the main subsidiary ofOrano S.A. It is an industrial group active in all stages of theuranium fuel cycle, includinguranium mining, conversion,enrichment, spent fuelreprocessing, and recycling.[1][2]

The company was originally created in 1976. In 2001, it became part ofAreva; its name was changed toAreva NC in March 2006.[3][4] As a result of restructuring of Areva, Areva NC became part of Orano and changed its name to Orano Cycle.

History

[edit]

In 1976,Compagnie générale des mines was created based on the uranium production activities ofCommissariat à l'énergie atomique (CEA). Later it was renamedCompagnie Générale des Matières Nucléaire (COGEMA). As of 1999, COGEMA was majority owned by CEA (81.5%) with minority owned byTotal S.A. (15%) andTechnip (3.5%). It also owned stakes inFramatome andEramet.

In June 2001, Cogema became a part of the Topco group which was renamed Areva in September 2001. In 2006, Cogema became Areva NC and began the construction of a new uranium enrichment plant at theTricastin nuclear site. In 2008, Areva NC launched the Comurhex II projects for new uranium conversion plants atMalvési and [Tricastin sites in France.

In 2018, Areva NC changed its name to Orano Cycle to reflect the restructuring of Areva.

Operations

[edit]

Areva NC is based in France and with its subsidiaries has a presence in more than 30 countries. It employs approximately 19,000 people worldwide. In France, it operates thereprocessing plant at La Hague, theMarcoule nuclear site, the Pierrelatte nuclear site (Tricastin nuclear site) and theCadarache center.

Orano Cycle has uranium reserves inNiger, Canada, Australia andKazakhstan. The last mine operation in France,La Société des Mines de Jouac, closed in 2001 when its reserves ran out.

Niger

[edit]

Concessions

[edit]

Areva NC's Niger operations consist of three concessions near the town ofArlit, runs as joint ventures with (minority) stakeholders from the Nigerien government and smaller foreign investors. Arlit was in fact built in the midst of theSahara to support these operations, and has a large expatriate population employed by Areva and its subcontractors. These ventures areSomair (Société des Mines de l'Aïr)[5] which operates an open pit uranium mine, andCOMINAK (Compagnie Minière d'Akouta).[6] These two mines accounted for 3,093 metric tonnes of uranium in 2005, almost 10 percent of annual global production and 30% of French consumption and 32% ofNiger's exports, but less than 5% of Niger'sGDP.[7] The increase in the cost of uranium on world markets in 2006 (more than 46%[7]) will enable Niger to triple its revenues sourced from Areva.[7]

2007 conflict with Niger

[edit]
Main article:Tuareg rebellion (2007–2009)

On 25 July 2007, the CEO of Areva-Niger, Dominique Pin, was expelled from Niger (although he was in Paris at the time) on charges of supporting theSecond Tuareg Rebellion.[7] According toLe Canard enchaîné, this move fromSeyni Oumarou's government was motivated by negotiations concerning the uranium trade agreement, which was finally renewed on 1 August 2007.[7] Furthermore,Laouel Kader Mahamadou, who had resigned from his functions as secretary general of the Nigerien government to take a consulting job with Areva-Niger, was asked by the NigerianDGSE to remain in Niger instead of flying to France for an integration workshop until a "clarification of the situation" could be obtained.[8]

The sporadic fighting in the uranium-producing north halted Areva's Niger mining operations in late 2007, and expansion plans were only beginning to resume in February 2008, while the insecurity and uncertainty remained.

Prior to this, Areva also gained a concession in nearbyImouraren, which is hoped to double or triple their production in Niger. In January 2008, Areva signed a deal to invest over 1 billion euros into its three operations in Niger, increasing the share of revenues going to the government of Niger by 50 percent.[9] Areva is also being pressured by the opening for the first time of over 100 concessions for uranium mining in Niger, most notably to Canadian and Chinese firms.[10]

In July 2008, four French workers were kidnapped from Areva operations near Arlit, but quickly released. Nigerien rebels of theMovement Nigerien for Justice (MNJ) operations in early and mid-2008 affected transport of ore from Arlit. Despite the violence in the Aïr Massif, Areva NC and the Nigerien government were by later 2008 unhindered in their exploitation of the Arlit uranium mines and in the transport of its product by highway to ports inBenin.

Imouraren mine

[edit]

At the beginning of 2009, Niger and the French state mining company agreed a deal to build near Arlit theImouraren mine. Areva would hold a 66% stake to the Nigerien mining office's 33%. At a projected output of five thousand tonnes of ore a year, it would be largest uranium mine in the world by 2012, as the SOMAIR and COMINAK mines are phased out. The deal would make Niger the second largest uranium producer in the world, and included plans to construct a civil nuclear power station for Niger.[11][12] While Areva officials earlier in the year admitted the security situation makes it impossible to prospect at night, the operations of the mines were by December unaffected by the Tuareg rebellion.[13][14] Despite the 2007 awarding of nearly 100 prospecting contracts to firms other than Areva, the high-profile Chinese and Canadian projects were in 2009 not yet formalised.[15]

Long term relations

[edit]

Areva has been criticised both in Niger and the west for aneocolonial relationship with the former French colony, having obtained monopoly rights to mine uranium for nearly forty years, while Niger remains (as of 2006) the least developed country in the world.[16] There has been speculation that Areva was the primary vehicle (and motivation) for French government involvement in the Nigerien government's poor history of democracy and human rights since the late 1960s.

Areva argues that it is a good steward of the environment and a partner in development with the Nigerien people.The company stresses that most workers it directly employs in Niger are locals, and that the revenue generated by these mines is the single largest foreign exchange source for Niger.[17] When the population of Niger was exposed to a seriousfamine in 2005, Areva donated 130,000 euros in June 2005 to the food crisis coordination group of Niger, and 120,000 euros in July in the form of two planes loaded with food and organized byBernard Kouchner'sRéussir NGO. Nigerien critics point out that this aid amounted to 0.05% of Areva's annual profits of 428 million euros.[18]

In January 2008, a Swiss human rights group awarded Areva's Niger operations their "2008 Public Eye Global Award" for the "worst company in the world", citing charges of radioactive pollution, poor working conditions, and the deaths of a number of workers.[19] TheTuareg based rebel group fighting in the Arlit area has echoed these charges.[20]
