MOSCOW, May 7 -- Russia's OAO Norilsk Nickel (GMKN.RS), the world's largest nickel producer by production volumes, said Thursday its production outlook for 2010 will not be affected by Finnish nickel miner Talvivaara Mining Co. (TALV.LN) cutting its production targets for the year.

"Despite the cut, we keep our production plans unchanged, as we had envisaged the possibility [of Talvivaara's cut]", Norilsk spokeswoman told Dow Jones Newswires.

Talvivaara, which has been plagued by teething problems at its mine in eastern Finland, said it expects to produce between 15,000 and 25,000 metric tons of nickel in 2010, compared with a previous target of up to 30,000 tons.

Norilsk refines nickel, supplied by Talvivaara, at its Harjavalta plant in Finland. Disruptions in deliveries of raw materials by Talvivaara in 2009 led to a decline in Norilsk's nickel production, the company said in January.

Norilsk said then it expects to produce about 234,000 tons of nickel at its Russian operations and between 65,000 and 75,000 tons of nickel at its international operations.
