Reporter, You have pointed to a very sound challenge in the equation. The issue of decommissioning and disposal. Even though I am a supporter of the deal, I cannot disagree the immense challenge that is posed from the investment.
However, most of these are Uranium based plants. While India plans to start with Uranium plants, my understanding is once they crack the Thorium commercial viability, the plan is to use indegenius Thorium reactors. The deal will serve interim interests and also provide the startup the Thorium reactors need. We also have enough reserves of Thorium.
However, long story short, I understand that the Thorium plants rely on reporcessing and hence should have lesser wastes.
Yet disposal is a BIG BIG issue. Disposal is an issue in every nation that produces nuclear waste. Honestly, thats a good question the governement should answer.
