Nuclear reactor for the submarine is quite different to nuclear reactor for an aircraft carrier.
Its one thing to build a nuclear attack or ballistic submarine, but completely another thing to build a nuclear aircraft carrier.

The safety measures and various subsystems that goes into it in order to protect it from disaster is far more complex than a submarine - for a nuclear submarine to go horribly wrong you lost 150 people, but for a nuclear super aircraft carrier to go horribly wrong that will be 5000 dead people, plus all the investments that goes into building a huge aircraft carrier, ALL the aircrafts and helicopters that are onboard, all the weapons, stores and ammos, not to mention the cost of training 5000+ personnels to operate an aircraft carrier. It is just far too costly if something goes wrong, so that's why most of the country that dares to invest in a nuclear aircraft carrier takes decades in design and testing it.

That's why for all the countries that has developed the nuclear submarines, ONLY TWO COUNTRIES actually dares to put into production nuclear aircraft carriers - the french and the american. Not even the british and the russian try it - the latest Queen Elizabeth-class aircraft carrier is conventional, and there are no country that are planning for nuclear aircraft carrier in the foreseeable future.

It will take SEVERAL DECADES before China will embark on nuclear aircraft carrier, that is if they go the completely indigenous route. They get it sooner if they can get the french onboard to help them, but it is highly unlikely.

Also, let's not forget, why would China want a nuclear powered aircraft carrier? Are they planning to be the new global police? A nuclear powered aircraft carrier goes against the current (and even the near future) chinese strategy. China is only seeking to consolidate its near shore defence - maybe along the second island chain, and the aircraft carriers they planning to build are only going to run around these areas most of the time. The PLAN aren't going to send their precious aircraft carriers too far from their shore, at least not until they have enough number of them. So a steam-powered gas turbined aircraft carrier is more than enough to fit the PLAN strategy for the foreseeable future.

Believe it or not it's actually harder to put a nuke plant inside a boomer or fast boat than it is on a suface ship. I believe the primary issue for PLAN's reactors is not so much of installation but rather power generation.

To power a carrier you need exponentially more power generation than you do a sub and at this point I do not believe China has the tech that is mature enough and small enough to fit multiple reactors inside the hull of a 70K carrier that would compromise other functionalities of a carrier.

Another reason would be simply strategic like you said. You don't need CVNs if you do not intend to travel the world's oceans. If you don't often sailed more than a thousand miles off your coastline or home port a CV is probably much preferred.
China also do not currently have large enough overseas naval bases nor forward deployed CSG and probably won't in the near future.

Until PLAN has true naval bases in the Indian ocean, Atlantic, Med etc a CVN is probably not the top priority. I would say at least another 10 yrs before they have a CVN but it's more to do with because they can and not because they really need it from a benefits perpective.

Guys, no doubt the PRC is working hard to further quiet their submarines.

But this thread is about the PLAN carrier.

The discussion about PLAN subs has been deleted here.

Please got back on topic.

Erm... Who are you going to believe? The ONI or the Chinese internet forum armchair expert??
Does this "Vincent" have direct access to the Chinese submarine? Does he somehow manage to also gain access to AMERICAN submarine noise level too?

The American has been running up and down the SCS all these decades recording the Chinese subs noise signature, while same can't be said of the Chinese so I were you I wouldn't believe anything this Vincent has to say.

Dude, i built the link to the article in the title. Please go visit it before replying. The magazine is an official magazine from the government. Google translate this:

I don't believe in soothsayer or any other hocus pocus.Unless ONI employed clairvoyant or believe in Vodoo. There is no way they can predict noise level from still yet to be launched submarine. End of discussion. Vincent only post article from government media so he is not the author of the article capicci

Jiangnan shipyard 1600 ton gantry crane ready


153001r6wf6zzvxnxmkwmo_jpg_thumb.jpg

3月18日上午，在江南造船(位置 评论 新闻)长兴造船基地4号坞现场，举行了目前国内起重量最大、起升高度最高的1600吨龙门吊(产品库 求购 供应)交机仪式。振华重工(股票)与江南造船两家公司的代表签署了交机证书，标志着振华重工历时9个月时间、精心打造的龙门吊按期、圆满实现了交付。

该龙门吊最大起重量1600吨，翻身重量900吨，轨距158米，梁底净空高95米，是目前国内最高、最大的龙门吊。

据了解，江南造船长兴造船基地1600吨龙门吊于2015年3月18日签订采购合同，2015年6月8日开工，2015年年11月24日，总体吊装顺利完成，创造了4天完成总体吊装的历史记录。

项目在实施过程中主要节点进展有序，尤其是2015年11月底，项目部使用ZPMC自产的5000吨浮吊在不影响船厂生产的情况下，仅使用5天时间就安全、顺利地完成龙门吊的吊装工作。在随后的近4个月时间里，克服大部分工作都需在95米以上高空完成的困难，顺利完成电气接线、调试、试车、型式试验、取证等工作，如期实现项目各项里程碑计划，并由第三方监理公司进行全过程的监造，其主要性能和参数已完全达到合同、技术规格书及使用要求，获得用户的高度评价。

The morning of March 18, the Jiangnan shipyard (comment on the news) 4th docking site of Changxing shipbuilding base, current weight, the highest rise of 1600 tons gantry (buy offer) ceremony. Zhenhua heavy industry (stocks) and Jiangnan shipyard machine certificate was signed by representatives of the two companies, mark Zhenhua heavy industry over a 9-month time, carefully crafted gantry crane, successfully delivered on time.

The gantry crane at max weight of 1600 tons, rolled over 900 tons in weight, gauge 158 m, beam bottom clearance height of 95 meters, is currently the highest and largest gantry crane.

It is understood that the 1600 ton gantry crane of Jiangnan shipyard Changxing shipbuilding base on March 18, 2015 signed the purchase contract, started on June 8, 2015 2015 November 24, general installation successfully completed, created 4 days to complete the overall lifting history.

Primary nodes in the implementation process of the project progress in order, especially late November 2015 project ZPMC-5000-ton floating crane in the case does not affect the shipyard production, using only 5 days to safe, successful completion of gantry cranes of lifting work. In then of near 4 months time in, overcome most work are needed in 95 meters above high completed of difficult? 

ONI has a massive database of acoustic signatures on pretty much all known (and some unknown) types of surface and subsurface vessel.
I obviously do not know what other nations have in comparison but I seriously seriously doubt it comes even anywhere close.
USN have been gathering these types of data for many decades roaming all over the world, tailing all kinds of vessels etc .. not to mention data collected and shared from allied nations.
Anyway this is waaay off topic but I thought I put my 2c worth.
