Dont you find that it is a commendable feat? Let us hope that they will have no more nukes. But nuclear terrorists are embarking on a continuation of the nuclear war to reach 63000 MW by 2032. And of course grow further! And year after year the society will not get any electricity outside the nuke industry(cost per unit infinity).
There is no pure reason for the non harmonised.
The superior way
Use enjoyably living energy by pedal power driven generators via grid tie inverters plugged on to the grid. The Indian population at 100 watts per head will generate a peak power of 500 million people of 50000 MW in two years! Use vapour absorption ac and save 65000 MW electricity.
Think out of the box. People produce outputs useful to society like electricity. Their excreta are gratefully accepted by mother earth. Nuclear wastes must be isolated, practically forever from mother earth.
The illustration of Kuda 1, Kuda 2 and so on is rigourously put in the form of a Table for the Indian Nuclear Programme in the URL
You will note in the Table that even after 28 years the programme of 24000 MW capacity installation still is taking 8000 MW from society. Note that the programme does not stop at 24000 MW, it wants to have 63000 MW by 2032!
