You have no clue.
nuclear reactor is a boiler as well, the difference is using U235 instead of heavy oil.
If 003 use boiler, the Steam Turbine technology will be developed, and further evolved. 004 Nuclear reactor will use similar steam turbine. So that 003 and 004 will share quite a lot of sub system.
Boiler is not outdated technology at all.
Agree. Thanks.
Edit:
One more thing.
The need of China and US is different. US navy needs to cover Atlantic, Pacific and Indian Ocean.

It takes 19 days in 29 knots, or 32 days in 17 knots from Japan to British.

China from Sanya to West Indian Ocean only 4500 Nautical mile,11 days in 17knots, or 6.5 days in 30 knots.
Kitty Hawk max speed 32 knots, cruise speed 20 knots.
China 003 requirement is more similar to Kitty Hawk. Good enough to deter India and safe guard sea route.
While I guess 004 will replace the conventional boiler with nuclear reactor, keep using the same Steam Turbine, so the technologies developed in 003 will be continued in 004, less maintenance.
