any verification of this statement;
"Although the Arihant’s core is not designed to operate for the submarine’s lifetime and will need refueling, it does not have a hatch. To refuel, the hull will have to be cut open and welded back, as is the case for the Russian nuclear attack submarine, the Akula-II class that India has leased and operates as INS Chakra."
