Hopefully they can retool Dalian over time for building CV. Where does that leave the Guangdong shipyards? It looks like they are just building type 056 and type 054. With twice the population of Korea, they can potentially double the size of Korea's shipbuilding industry, by building more 052d, 055, 075, LNG carriers, LNG powered containers, luxury cruise liners and eventually CV.

The CSG megafacility in Changxing [misspelled it in my other post], like I already mentioned, consisting of three shipyard companies side by side, is more than capability of pumping out many carriers on their own, without Dalian or Guangdong shipyards involved. How many carriers do you actually need? Even Chinese posters seem to greatly underestimate the sheer scale of China's shipbuilding.

Dalian should be considered a backup, but it may not even be necessary. To certify them for the new carrier production, you not only have to retool but also have to retrain. Should you want to make Dalian build carriers too side by side with Changxing facilities, you can do it, but its not the best cost and time optimal. You still want to keep your costs down. Changxing has the great advantage of relying upon the educated and skilled population from the Shanghai area, much easier to find the highly skilled labor and management so you can scale your production. The area is also chock full of factories and other shipyards --- there are also two other shipyards in nearby Chongming island --- so you can further fan and subcontract production of modules or shift the labor around. Changxing island itself has plenty of spare room so you can keep building additional factories and even more drydocks.

Guangdong shipyards can do 056 and 054, but also PLAN auxiliaries, like ELINT ships, replenishment ships, tankers, AOEs, blue water tugboats, sonar surveillance vessels, coast guard ships, submarine tenders and so on.

If so, it would probably be at the Changxing Island (somewhere in Wafangdian county-level city under Dalian administration, with a similar name to JNCX) branch of Dalian Shipyard.
Currently Dalian Shipyard's facilities involving in buliding military products are too close to the downtown area . No one would want to manufacture a nuclear reactor there.

A nuclear reactor is only active once it is fueled. Up to then it is just a bunch of inert steel components.

I think China needs two carrier producing facilities to increase production and to enhance competition between yards.

Isn't virgin nuclear fuel quite harmless? Like you see photos of people handling highly enriched uranium pills in a glove box and everything. It's only fuel that's been fired and thus full of fast decaying (compared to uranium) daughter products that are dangerous and need robots to handle isn't it? I remember reading up on this when looking up how safe it is to launch nuclear thermal rocket upper stages.

You are correct.

It can be handled with rubber gloves basically.
It is only slightly warm to the touch. I think.

It is once you reach criticality with the fuel that the dangerously radioactive elements start to form.
For that someone has to start the reactor.

Woah, what? Enriched (even non-weapon-grade) nuclear material is highly, highly radioactive and must be handled with special equipment. You can handle it with bare hands, but it must first be encased in some kind of shielding. And no, those are not ordinary glove boxes with rubber gloves; they are all lined with lead, including the glass.

The above is just one example. For weapons-grade material, the linings are even thicker, or they use remote-controlled robotic arms lined with radiation shielding to accomplish the same.

Come on now!

End off-topic post.

They can be handled with rather thin gloves IF they are sealed, Uranium decay(Does China have any plutonium reactors?) only produces alpha and beta particles which are pretty easy to block with a thin layer of metal.

After time in the reactor, the sealing material itself becomes radioactive as well, so the rod becomes far more dangerous.

Stop now, this is off topic, it has been requested already once and now it is enough!
