Importing nuclear plants is a quick-fix solution to the present power crisis.
Nuclear technology is sensitive. Even if the nuclear deal goes through, it will take time to buy and setup new reactors. We have examples of the French reactors in China, and the Russian reactors in Kudankulam, India. It will actually take longer to setup foreign reactors compared to indigenous ones. Just the negotiations and legal formalities could take years. It will be at least eight years before we see the first power. So importing reactors is certainly no quick solution. For the short term, we will still have to rely on coal and hydroelectricity.
