India's prime minister, Manmohan Singh, says India will open 65 percent of its nuclear power reactors to United Nations inspections but not the experimental fast breeder reactor.
He told parliament no part of the process will compromise India's national security.
Mr. Singh was giving details of a civilian nuclear deal with the United States under which India has agreed to separate military and civilian nuclear facilities, and open the civilian facilities for U.N. inspections.
If signed, the pact would allow nuclear powers to provide technology and fuel that India needs to meet the energy needs of its booming economy.
The two sides have been holding talks to seal the deal before President Bush visits New Delhi this week.
Fast breeders use spent fuel from other reactors to produce plutonium, which can be used for both generating power and making bombs.
