The whole point he is making is that even IF builders follow the building codes, the codes themselves are not conducive to saving energy as they were not done with saving energy in mind.
The point is that US haven't built one in decades. Therefore its possible that they dont have up to date technology in nuclear reactors. But I don't agree with his point totally.
The point he is trying to make is that it is tolerable for the 'Nehru dynasty' Congress party.
On this point, I agree partly. But it takes a HUGE investment to come up to a 70% level that not many countries can afford plus there is the problem with adequately dealing with nuclear waste, radiation etc.
