S4 power rating seems to be reported lesser than the actual by a layman’s logic:-
1.VLS doubled. Minimum 18 tons added.
2. Length increased by 14 m. It is longer than the Akula 190 MW reactor.
3. New propulsion system.
4. HY 80 cat steel being mfr at SAIL plant.
In my guestimation the reactor should be between150 to 190MW and not 82.5 MW to derive meaningful Shaft Power.
