Went ahead this morning to research some quality work on this subject. Over 2,000 papers have been written in India on this subject so will be quite difficult to get the entire list to you. Here are some quality works that have been done to help understand more about the subject:
1. Starting with NPR and leading experts in the field on a talk about thorium nuclear reactors:
I am afraid that locating a database that would hold every single paper written on this subject in India would be difficult to get access to. There are a number of well run websites that would have papers written on this subject, starting with Google Scholar which is free and has a wealth of information to view. I would also suggest looking at your local college and/or university library to see what they may have access to in terms of a scholarly database. Something though that would have everything written in India though I am afraid I am not aware of.
Best of luck in finding what you are looking for as a refund was made by the moderator.
