"There is no explicit mention of nuclear testing in the NSG waiver," he said making it clear that the exemption granted to India by the 45-nation cartel met all requirements of the Department of Atomic Energy.

"We have made no legal commitment on nuclear tests," Kakodkar said underlining that India has already made a unilateral, voluntary moratorium on conducting atomic tests.

"Today is an important day as we have achieved a major breakthrough," he said and termed the waiver to India as ‘unique’ as it will open the doors for the country to take part in international civil nuclear commerce after 34 years of isolation.

Asked about the amendments India had to accept to win over skeptical NSG members, he said, "there is nothing significant. You can see it for yourself when the waiver document is made public by the NSG shortly. It is a straightforward document."

"There is no specific targeting of India on anything," the country's top nuclear scientist said.

"I think it is clear that people have understood and recognised the importance of this exemption for India from India's track record, behaviour and energy needs," he said when asked what he felt led to the waiver from the guidelines of the cartel that controls international nuclear trade.

Kakodkar said India's three-stage nuclear programme will continue.

Kakodkar said there was a good amount of urgency for enlarging the share of nuclear power and the NSG waiver will enable bringing ‘additionalities to the domestic nuclear programme.’

He said India will talk to all countries engaged in nuclear trade and ‘certainly with the US’.

"We have been talking about use of nuclear technology for national development and also meeting national requirements while we have the strategic programme which will go on. Our energy requirement is very large and the opening of civil nuclear commerce will enable is to meet both objectives," Kakodkar said.
