* Agreement paves way for end of Canadian ban
* However, some details still need to be worked out
* Canada says deal will boost its economy
* India wants to lift its nuclear capacity
Canadian firms will be able to export uranium and nuclear reactors to India for the first time in almost four decades under an agreement between the two nations, their prime ministers said, but more work is needed to implement the deal.
Once implemented, the agreement will end a ban on nuclear cooperation Canada imposed in 1976 after India secretly exploded its first nuclear bomb in 1974, commonly called the "Smiling Buddha", using material from a Canadian-built reactor in India.
"Being able to resolve these issues and move forward is, we believe, a really important economic opportunity for an important Canadian industry, part of the energy industry, that should pay dividends in terms of jobs and growth for Canadians down the road," Canadian Prime Minister Stephen Harper said on Tuesday on a visit to New Delhi.
It was not clear how quickly the deal will take effect. The two countries signed a nuclear cooperation pact two years ago and on Tuesday said they had concluded negotiations on the "administrative arrangements".
However, a joint committee also announced on Tuesday that it would still have to iron out some issues before trade begins, and an official with the Indian delegation said the announcement about concluding negotiations was "kind of face-saving".
India aims to lift its nuclear capacity to 63,000 MW in the next 20 years by adding nearly 30 reactors. The country currently operates 20 mostly small reactors at six sites with a capacity of 4,780 MW, or 2 percent of its total power capacity, according to the Nuclear Power Corporation of India Limited.
Canada's ambassador to India, Stewart Beck, said on Monday his country wanted to be able to track all nuclear material, but that India felt it only needed to report to the International Atomic Energy Agency.
It was not immediately clear what safeguards there would be to ensure that Canadian material did not get used again for making nuclear weapons, an issue that had been a key obstacle to the agreement.
RACE AGAINST AUSTRALIA
Harper said the Canadian Nuclear Safety Commission had worked to "achieve all of our objectives in terms of non-proliferation".
Canada is in a race against Australia, its strategic ally but a commercial rival in the uranium business. Australia is also trying to nail down safeguards under which it too could sell uranium to India.
Opening up the huge Indian market would be a major benefit to Canada's Cameco Corp, the world's largest publicly traded uranium producer.
Another potential beneficiary is Canadian engineering firm SNC Lavalin, which bought the government's commercial nuclear division, which designed the Candu reactor that is in use in numerous countries.
Harper also said Canada welcomed foreign investment, after the country temporarily blocked Malaysian state oil firm Petronas' C$5.17 billion ($5.19 billion) bid for gas producer Progress Energy Resources on Oct. 20.
Late on Friday, Canada extended to Dec. 10 its review of a $15.1 billion bid made in July by China's CNOOC Ltd for Canadian energy producer Nexen Inc. Reuters had reported on Wednesday that an extension was likely.
"Those decisions have to be taken looking at the global evolving economy in which we operate," Harper said.
