This is my vision of the route that the Dept of Atomic Energy must take to move our country away from a hydrocarbon economy to a nuclear and renewable resource based economy. Objective: To achieve power generation capacity of 300 GW through nuclear power by 2050 Approach a) Offshore Mega Nuclear Installations â€“ Target 140 + GW b) Modular Underwater Nuclear Installations â€“ Target 120 GW c) Coastal Fuel Breeder Nuclear Installations â€“ Target 40 - 80 GW 1. Offshore Mega Nuclear Installations High Voltage DC transmission results in losses of less than 3% per 1000 kilometers. Based on this principle, creating massive nuclear installations in offshore locations is viable both from a scalability as well as risk (or lack of it) perspective. The primary objective of megaplants would be to power the industrial sector that typically requires high density power. These are four prospective locations a. Cherbaniani Reef: Lying approximately 350 to 400 KM away from Mangalore, Margoa and Talasshery of the western coast of India, this Lagoon is the northernmost in the Lakshadweep Archipelagos. The closest inhabited island is Cheltah island which is 120 km away. The lagoon area is 172 square kilometers with very little land area. Due to the entire lagoon being extremely shallow, creating an artificial island of 5 sq kilometers will result in a total cost of not more than 3 billion USD. Creation of the island itself needs to be done in a phased manner spread across 30 years as the plant reaches full capacity thereby offsetting the cost of island creation through revenue of the plant. Timeline 2020 â€“ Island Area : 1.5 square KM, Power generation : 0 MW 2025 â€“ Island Area: 2 Sq KM, Power generation 3000 MW 2030 â€“ Island Area 3 Sq KM, Power Generation 10,000 MW 2040 â€“ Island Area 5 Sq KM, Power generation â€“ 40,000 MW Due to the remote location, this plant could be scaled much larger to approach 100, 000 or more if by then newer and more efficient sources of energy have not become technologically feasible. The red lines indicate possible distribution centers receiving power. b. Chank Tapu and Nora Tapu Reefs in the Gulf of Kutch: These reefs lie approximately 20 KM off the closest coastal point of a very sparsely populated Kutch. The closest population centre is Jamnagar which is more than 60 KM away. As above landill costs to create an artificial island on the reef would be approximately the same, maybe a little lesser as there is already some land above sea level and the water is more shallow. The timelines would be very similar to the above and hence a targeted generation capacity of 40,000 MW by 2040 Proximity to Pakistan is a concern but in the event of war, my assumption is that India will completely flatten the Pukes and gain territory we have to accept some collateral damage anyway. c. Hare Island off the coast of TN: This island is only 5-6 KM away from the mainland and hence I would restrict it to a 20,000 MW plant but timelines would be much tighter targeting completion by 2030 d. Wheeler Island Cluster: This islet cluster is also close to the coastline but away from population centers and hence 40,000 MW can be targeted. As there are already many islets, only minimal reclamation costs will be involved. The size of India's economy in 2040 would be such that creating completely new artificial islands to house offshore mega plants like these would become relatively cheap as an investment and beyond 2040, that decision would be completely dependent on the technological feasibility of alternate energy systems.
