In fact, the Russian government has also threatened to increase the costs for Kudankulam 3 and 4, if they are brought under the Indian liability law. The government also stated that the delay in commissioning Kudankulam 1 and 2 has increased the cost from Rs 13,171 crore to Rs 17,270 crore.

South Korean nuclear reactors are generally believed to be the cheapest, the South Koreans having won a prestigious UAE nuclear reactor contract.
