Of course an Indian would believe that nonsense. I got a bridge to sell you.
America says a lot of shit regarding their technology. You have to refuel every 5+ years for nuclear reactors. And no, you dont have to cut anything open.
LMAO, I can assure you, the latest reactors developed for the latest classes of American boats, as well as Yasen-M and Borei-A don't need to be refueled every 5-7 years, and you actually very much do have to cut open a submarine hull to refuel the reactor, as was done on older American and Soviet submarines, the only exception is the French, who build in a specific hatch into the hull, but this is a function of them unifying their reactor designs for both surface and submarine fleets which makes such a solution appropriate.
Older subs maybe. I doubt you need to do that on a Borei or Yasen. If it is still the case, seems rather odd they would continue the trend. Maybe refueling isn't the 5 years anymore but hence I added the + in there.
