Where is the need to be nuclear anyway... they are not made to project forces to the other side of the globe like the US carriers. They will be able to be resupply from China in their zone of operation.Note that 2 elevators won't be an issue if they are large enough to lift two fighters at a time.
Also, is it confirmed that 003 will have conventional propulsion considering that the white blobs are suspected to be boilers? No more retarded talk about radiation shielding and 'lack of smokestack hole' in the vain hope that it would be nuclear?
