Janes: China hopes to develop next-gen carriers

In order of risk, there are 4 imminent dangers for war

1. Korean Peninsula
2. Diaoyu Islands
3. SCS
4. Sino indian border

The destroyers are important to counter a possible blockade in the event of 1/2/3; they will be needed if a war # 4 drags on.

An aircraft carrier is most important for 3 and 2. It is helpful in 1 and 4

What do you think?

Our carriers/destroyers/nuclear subs will be the backbone of our global navy, and our only legitimate opponent is the US navy.

Otherwise there is no reason to build these monsters in such speed.

A rumor out that says there are going to be portions of the carrier that are going to be seen this year or next, most likely a conventional carrier after that i'd expect a nuclear powered one.

BTW, China's aircraft carrier is indeed nuclear + EMALS.

Do you have a source of this ?

Imagine we have our own UCAV that is comparable to X-47B,

We do the sharp sword.

While you have the EMALS, the propulsion of the AC has to be nuclear, the QE class of UK is not practical, a small 65000 tons and conventional carrier is not what PLAN wants to acquire.

Agree on that nuclear AC has to be fueled once every 10 or 20 years conventional every now and then.

From Sr Colonel Du Wenlong, he is opposed against the conventional AC, and China should directly jump into the nuclear AC with EMALS.

I think carriers are good for 1, 2 and 3. Anyway, does China have capability to quickly make nuclear powered carriers? It would take some time.

Yes building a nuclear carrier is a humongous task. We are capable of building nuclear power plants on land and nuclear submarines. But the latter are less than 10K tons while a nuclear aircraft carrier will have a displacement of 100K tons. So we can see that big difference here.

Year 2020 is the initial target

China has the technology to build nuclear power plants for 100,00 tonne supercarriers.

It is a question of using multiple power plants for a carrier as opposed to a single plant on a nuclear submarine. Also the difficult task of power plant miniaturisation is not required on a large super-carrier

Remember China has better nuclear power technology now than the US did in the 1970s when the Nimitz class carriers first appeared.

The most difficult part will be creating the hull as China has no experience in building carriers. Studying the Varyag should help but the challenge will still be immense.

Building a nuke plant on land is a differenct tech from putting it inside a 100K ton aircraft carrier. That also requires miniturization as well though not to the level of <10K ton submarine.

The hull is a difficulty because it requires a whole lot more complex technology than a 300K ton tanker or LNG vessels which we are building.

Yes, what I meant is that the level of miniaturisation is not as much as on a SSN.

More info for you and those members who are interested:

The most advanced modular project is in China, where Chinergy is starting to build the 210 MWe HTR-PM, which consists of twin 250 MWt high-temperature gas-cooled reactors (HTRs) which build on the experience of several innovative reactors in the 1960s to1980s.



Medium and Small (25 MWe up) reactors with development well advanced

NHR-200

The Chinese NHR-200 (Nuclear Heating Reactor), developed by Tsingua University's Institute of Nuclear Energy Technology (now the Institute of Nuclear and New Energy Technology), is a simple 200 MWt integral PWR design for district heating or desalination. It is based on the NHR-5 which was commissioned in 1989, and runs at lower temperature than the above designsh. Used fuel is stored around the core in the pressure vessel. In 2008, the Chinese government was reported to have agreed to build a multi-effect distillation (MED) desalination plant using this on the Shandong peninsula.

ACP100

China National Nuclear Corporation (CNNC) has designed a multi-purpose small modular reactor, the ACP100. This is based on the larger ACP (and CNP) units, has passive safety features and will be installed underground. It has 57 fuel assemblies 2.15m tall and integral steam generators, so that the whole steam supply system is produced and shipped a single reactor module. Its 310 MWt produces about 100 MWe, and power plants comprising up to eight of these are envisaged, with 60-year design life and 24-month refueling. Or each module can supply 1000 GJ/hr, giving 120,000 m3/day desalination (with MED).

CNNC New Energy Corporation, a joint venture of CNNC (51%) and China Guodian Corp, is planning to build two of these at Zhangzhou city, Putian county, at the south of Fujian province, near Xiamen, as a demonstration plant. This will be the CNY 5 billion ($788 million) phase 1 of a larger project. CNNC said that the units could provide electricity, heat and desalination. Construction time is expected to be 36-40 months, starting in 2015. It involves a joint venture of three companies for the pilot plant: CNNC as owner and operator, the Nuclear Power Institute of China as the reactor designer and China Nuclear Engineering Group being responsible for plant
construction.

US Predicts china to have at least 5 carrier fleet which makes sense considering china's vast cost line, Taiwan, SCS and its legitimate aspirations in IOR. By 2040 PLAN should definitely have 5 carrier fleet.
