would it be PWR or some exotic variety?

Well China has been building naval reactor since 1971 with Type 91 submarine. Infact that is the beginning of China civilian nuclear energy. And over the year they keep improving the efficiency, shielding, noise and compactness. China has build civilian 100 mw nuclear reactor ACP 100 But of course they are different than naval reactor since space is constraint in naval operation and need long refueling period So naval reactor are highly enriched and high flux reactor. To generate higher steam temperature. Noise is another constraint for submarine. So they are natural circulation reactor with built in steam generator to reduce piping. But the balance of power is the same whether it is nuclear or conventional power plant. I have no doubt they are working on it In fact they did announce the start of designing large naval reactor maybe 2 or 3 years ago.
China is highly developed when it come to nuclear energy basically self sufficient in every aspect of nuclear energy
Here is the father of Chinese naval reactor
Chinese naval reactors
- MAY 10, 2017
On April 25, 2017 the Changzheng-1, its first Type 091 Han-class nuclear powered attack submarine. It entered service in 1974 and .
China launched its nuclear-powered submarine program in 1958, soon after starting its nuclear weapon program. To avoid the nuclear submarine program competing with the nuclear-weapon program for scarce HEU, according The Secret Course, an authoritative book on China's nuclear history, the decision was made to use LEU fuel for naval reactors.
A land-based prototype naval reactor began tests in May 1970, becoming fully operational in July 1970. The test of this reactor core ended in December 1979 and the spent fuel was discharged in 1981. China's first nuclear-powered strategic ballistic missile submarine (Type 092 Xia-class) .
China's official nuclear history (Modern China's Nuclear Industry, published in 1998) indicates that the first generation naval reactors in both the Type 091 and the Type 092 vessels may have used LEU enriched below 5% uranium-235 (comparable to modern nuclear power reactor fuel). The first generation naval reactors were mainly in use from the early 1970s to mid-2000s.
Zhang Jinlin, the chief designer of China's second generation nuclear-powered submarines, has said that the first of the second generation nuclear-powered attack submarines, the Type 093 Shang-class, was delivered in 2006, and the first of the second generation ballistic missile submarines, the Type 094 Jin-class, was delivered in 2014. China five nuclear powered attack submarines and four nuclear-powered ballistic missile submarines. These are all believed to use LEU fuel.
It is possible that China has adapted its second generation naval reactor for use as a small commercial power reactor. The China National Nuclear Corporation's ACP100 reactor . The ACP100 reactor as a 310 MWt (100 MWe) small modular PWR, using 4.2% enriched LEU fuel, with the core and cooling system integrated inside the pressure vessel and a passive safety system. This may suggest China has developed a compact integrated naval reactor, similar to ones previously developed by France and Russia.

Nimitz Class has 4 elevators + 4 cats
Ford Class has 3 elevators + 4 cats
003 has 2 elevators + 3 cats
Now we dont know how many weapons stations and location of the fuel stations on the 003 but I assume the deck is optimised
and we also dont know if its elevators can lift 2 x J15 simultaneously
so the sortie rate I would predict is lower than the Ford Class but possibly higher than the Nimitz Class considering the size of the deck for the 003 if the elevator can take 2 fighter aircraft
depending on the weapons elevators distribution system and how advanced it is I would say with 48 x J15 on board this Carrier could do 150 sorties per day or roughly 3 sorties per day per aircraft
Ford Class has 3 elevators + 4 cats
003 has 2 elevators + 3 cats

The service life of J15 will probably end by 2030. Aircraft that follows it will likely be smaller as manning requirement will likely be phased out over the next 10 years or so. so the probability that elevator not quite large enough to hold 2G 15th at the same time will be able to hold two embarked tactical aircraft of any kind during thr remaining three-quarter of 003 service life seems high
Oh, so it's mainly because of the air control part. I see. Thanks for the answer.
J-15 will be definitely in service by 2030.Because small stealth can’t carry large anti-ship missile or cruise missile, which will be primary tasks for Chinese aircraft carrier. For the same reason, F-15 and F-18 will still be in service by 2050.
Doesn’t EMAL and IEFP sell as a bundle? I think most power of ship will be needed to generate electricity to power frequent launches, which naturally requires IEFP for the flexibility of power distribution. Isn’t Ford the same deal?
I seriously doubt F-16 or F-18 will remain in frontline service much beyond 2030-2035. I also think china will develop some dedicated stealthy strike aircraft similar in concept, if not the necessarily overall design , of the cancelled A12 carrier borne flying wing attack bomber, to take over long range strike role from the J15.
it could be a navalized JH-XX, or a wholly new aircraft

With the layout of the deck of 003 now apparent, what does this layout suggest in terms of operational use? A large deck has been provided, together with a further reduced Bridge footprint, and only two aircraft lifts. As with the development of the USS. Ford-class, the reduction of one lift provides more deck space for sorties (not just for storage but actual preparation), given the same sized deck. A 003 carrier, of the same dimensions as the one building but with a Port-side lift, would have greater capability to more aircraft between the deck and hangar, but reduce area for preparing aircraft for operations. As the hangar is primarily for maintenance and repair, the reduction of a lift reduces the ability at which aircraft can be moved to and from maintenance and operations. Given this, it is likely that the operational focus of 003 is high tempo aircraft operations but shorter deployment periods. This suggests that 003 is optimised for high intensity operations out to the second island chain, while not precluding “showing the flag” deployments further afield.
It is not an opinion, but a fact, Boeing is developing F-15EX for air force and F-18E/F Block III right now, these latest iterations will definitely still be in service by 2050.
To attack US navy, Chinese can’t sink aircraft carrier with bombs, it will be suicide missions even with stealth fighters. Stealth fighters can still be detected in short range. They must use super sonic missile. A stealth fighter which has a large enough weapon bay to carry super-sonic anti-ship missile will be much bigger than J-15
