Moscow and Oslo have signed a landmark deal that allows Norwegian companies help clean up Russia's nuclear debris. The long-overdue agreement should also pave the way for companies to work on Russian nuclear projects. Norwegian officials say the deal became possible when Russia stopped insisting that Norway should pay for any accidents during the clean-up processes. Oslo has already budgeted a substantial amount of money for seven remedial projects, five at radioactive dumps around Murmansk on the Kola peninsula and two at nuclear sites elsewhere in Russia.
