1. If India becomes dependent on nuclear generated energy for sustaining growth then we are susceptible to blackmail from US and western world to not improvise or gain new knowledge in nuclear millitary technology because for this nuclear tests are required which are prohibited in this deal. Therefore India at one day will have to decide whether to test nuclear weapons and loose its growth.
2. If ever need arises to attack India in future by western world (it will only happen after decimating Russia, China and Middle-East) then IAEA will simply say India is using civilian reactors for millitary purposes and NATO will take it upon itself to dis-arm India through either sanctions or Millitary force.
India's Take:
India already has suffient knowledge to maintain and enhance nuclear arsenal without further testing. Therefore uranium supplies will never be stopped in future. or India understands what US is upto but silently agrees that there will never test again and be happy with a small and primitive nuclear arsenal to defend against Pakistan, for we need energy badly to grow and take care of millions of poor in India.
