Reliability Problems
Later, two nuclear-powered submarines were fitted with turboelectric drives, but they experienced reliability concerns over their service lives, resulting in underpowering and extensive maintenance. By 2013, only the French Nacy’s nuclear-powered Triomphant-class submarines were using turboelectric drive. The electric drive concept is merely one component of a larger propulsion system. It will be unable to replace nuclear reactors or steam turbines.
The Prime Designer And Manufacturer
In 2014, Northrop Grumman was chosen as the primary designer and builder of the turbine-generator units. They are necessary because the turbines turn the thermal energy of the steam into mechanical energy. The mechanical energy is then converted into electrical energy by the generators. This energy is then used to power onboard systems as well as the propulsion mechanism of the electric motor.
