China Signs Nuclear-Powered Icebreaker Deal

A cooperation deal signed between China National Nuclear Corporation and China State Shipbuilding Corporation will accelerate the development of nuclear-powered icebreakers and maritime nuclear power platforms, according to local media reports.

China currently has one diesel-powered icebreaker, the Ukraine-built Xue Long, but another has been slated for construction. The new nuclear-powered design for the Polar Research Institute vessel is expected to cost more than a billion yuan ($154 million) and take around two years to build. Construction is expected to begin at the end of 2016.

The vessel will feature higher ice capabilities, better research capabilities and be more comfortable and environmentally friendly than Xue Long. It is expected to be 122.5 meters (400 feet) long and will be able to break ice of up to 1.5 meters (five feet) thick at a speed of around two knots. It will be able to operate bow or stern first using two ABB Azipod units with combined power of 15MW.

China commissioned its latest naval icebreaker, Haibing 722, in January. The vessel is assigned to the Chinese Navy's Northern Fleet to patrol the Bohai Sea.

China’s interest for the Arctic has steadily increased over the last decade, and the country is now an observer to the Arctic Council. In northern Russia, Chinese investments are seen in both Yamal LNG and other petroleum projects.

It is a floating nuclear power station.

Any updates on this subject?

LOL, looks like they finished developing the naval nuke. If they are using it on civilian ships, it means the military version is already operational.

Last week they announce IEPS for a research ship. It seems the pieces are falling into place. I am very sure 002 is nuke powered with IEPS and EMALS now.

Actually NO.

Civilian tech and military tech have totally different requirements.

In military, noise, and heat emission is a BIG problem, since it gives away position. A good, silent nuclear plant with minimal noise and heat emissions is an engineering marvel.

This is NOT the case with civilian tech, where noise and heat emissions may not matter as much.

Is there any possibility this civilian reactor is a stripped down version without those noise/radiation shields?

not gonna help much for a 100k t carrier carrying 50+ noisy aircraft

LOL, this is a good one. He is thinking those reactors are for submarines. . Basically a carrier reactor would just be having a higher power output.

I am looking more from the perspective a submarine.

Submarines are the hardest for which one needs perfection.

Submarines biggest, and perhaps the only strength, is stealth.

A noisy submarine is useless.

And it is EXTREMELY HARD to build a silent nuclear reactor, with minimal heat emissions. You need extraordinary precision engineering, and brilliant design.

Just because India cannot make it, it doesn't mean China can't bro. That article clearly says it was for surface ships.

It can't be.

The whole design changes. There is no "shield" that you put on, and voila, noise and heat go away.

The noise factor has to be factored in right from design.

This is called strawmanning.

You are claiming that I made an argument that I didn't make.

I am talking that simply because China is working on a civilian nuclear reactor proves nothing regarding militarily usable ones. In fact, civilian reactors are mastered before military ones, due to the complexities involved in the process.

But it was clearly a surface ship reactor, this reactor was meant for the carriers bro.
