How long does the nuclear fuel last?

The submarines that we have built during the past several years have fuel that will last for the life of the ship, which is approximately 33 years. By not having to refuel, the submarine can stay operational and on the front lines defending the country for far longer periods of time.

Nuclear fuel has an indefinite life, due to the decay rate of radioactive products. However when fitted to the propulsion system of a submarine, the fuel is renewed at every “re-fit”, which is when the submarine receives a major overhaul. Each submarine is expected to receive a re-fit every 5 -7 years.
