Responding to Pakistan President Pervez Musharraf's [Images] charge that New Delhi's uranium enrichment technology "could be a copy" of Islamabad's centrifuge design, India on Monday asserted its "entire nuclear technology has been developed indigenously and action consistent with responsible behaviour."

"Our technolgy is based on our indigenous research and development and action consistent with responsible behaviour," Chairman of Department of Atomic Energy Anil Kakodkar told PTI.

Earlier, a DAE spokesman said, "All we have to say is that our entire nuclear technology has been developed through our indigenous R&D programme and we have always conducted ourselves in the most responsible manner."

Putting the entire blame of Pakistan's record of nuclear proliferation on disgraced nuclear scientist A Q Khan, Musharraf, in his book In the Line of Fire has alleged that several Indians worked for Khan's network in Dubai and India's uranium enrichment technology "could be a copy" of Pakistani centrifuge design.
