Officials said that the major impediments in signing the deal with the Russians were few clauses of the Civil Liability of Nuclear Damages Act (CLND), 2010, and differences over these have been settled now.
The liability clause gives the operator (NPCIL) the right to recourse and seeks damage from the supplier, which in this case are the Russians.
It also demanded that India should not bring Unit III and IV under the CLND Act's ambit as the original agreement of nuclear cooperation between India and Russia was signed way before the law came into existence.
This was one of the reasons why the deal could not be signed between India and Russia when Prime Minister Manmohan Singh visited that country in October last year.
