Has anyone calculated the total energy requirements of 003 given its larger size than its predecessors and the fact of its using EM catapults rather than steam? The engine uptakes look very close in size to those on 001 and 002 so is it possible that 003 uses a hybrid of a nuclear and conventional power-plant like the Soviet Kirov class battle cruisers?

yes. One member here did so.
EM cat consumes less energy than steam cat.
This has also been discussed here too, but it was a view by minority, I am not one of them. EM consuming less energy itself was enough to kill this hybrid idea, besides, CV does not need the kind of fluctuating power demand as a battle cruiser.
If you are interested, please use the "search thread function", I don't think there is any stone that has not been turned.
Thanks for the reply. When you say that the EM catapults use less energy than steam are you saying that it is more efficient to generate electrical energy than to use steam to pump the cat? If so what is your source? Do we even know how many Megawatts an EM cat complex would consume?
PVG is so close to Jiangnan
Generators with fossil boilers can be up to 47% efficient, but even old ones are 35%+ efficient.
Linear motors are 85% efficient.
Steam catapult is claimed to be 5% efficient.
Not just that. All 5 runways of PVG are parallel in the direction from PVG to Jiangnan (and Hudong-Zhonghua).
(The placement of the lines over the runways at PVG are approximate, but you get the idea)
If the planes are approaching from the north and landing in PVG, anyone onboard certainly would have a good bird's-eye-view of Jiangnan (and Hudong-Zhonghua) right underneath their flight paths.

Steam boilers are emergency/auxiliary power on Kirovs, not a boost. Period.

AFAIK, that couldnt happen in any way because the ship was not yet complete enough to even be put in the water. Remember that the ship was never launched into the water. Also, the USSR only ended in the end of 1991. The RSFSR (soviet russia) didnt have any military power, so in no way they could do that.
Of course your ideia is just a "if", so its fine. But IMO, the fujian is more beautiful (and of course, more modern-looking) than ulyanovsk, not to mention the capabilities, even though the ulyanovsk was nuclear-powered. So, i think that the chinese would rather have a second fujian. But the images are great.
Yes, that is what I meant. The calculation is E2E, energy from the steam boiler of the main power plant to the launch shuttle during the full length of an air operation.
Please check the thread There is detailed calculation involving many members. A good start is to read this paper "Electromagnetic Aircraft Launch System - EMALS" by Michael R. Doyle, Douglas J. Samuel, Thomas Conway, Robert R. Klimowski of Naval Air Warfare Center, Aircraft Division, Lakehurst
If you have further questions, it is better to put them up in that dedicated thread.
They need to relocate the top secret shipyard.
