For inert gasses or Helium used as coolant 700C to 1000C in certain areas is in experimental stages pertaining to HTGC reactors. It is being evaluated. Supercritical CO² may be used in terminal stages for power generation in secondary or tertiary loop but not at 700C⁰. Even at lower temperature it needs high pressure container casings.
No. The higher temperature the higher efficiency is just like supercritical steam generator, but no special limit on the lower end.
超碳一号 the sCo2 generator that entered service few months ago uses waste heat from steel mill whose waste heat is about 400C instead of 650C in a melton salt reactor.
There is a thermal power plant from 2020 that runs 5MWe sCo2 turbine instead of steam turbine in China using conventional coal fired boiler.
At 330C a PWR's turbine is running subcritical steam because water's supercritical point is 374C and 220bar. However that is well above sCo2's supercritical point. So in theory sCo2 turbine can already be used by conventional PWR.
The key here is that one should not make a relationship between supercritical state with higher temperature. Specifically in case of CO2 one should not make a releationship with pressure either because CO2 reaches supercritical state at a much lower presure than waster steam.
The real challenge of successfull application of sCo2 is heat exchanger design because CO2's surface heat exchange capacity is only 1/3 of water.

Interesting development indeed!
The boat that was launched at Bohai on February 9 wasn't actually a 093B SSN, but the first 095 SSN! No detailed imagery on the SSN has been provided in the article, but I suppose people at Naval News have access to them.

Similar lenght, wider beam compared to the 09III, 9-10k tonnes, pump jet, maybe retractable dive planes and potentially single hull or hybrid hull design.
Really hope the image provider let them publish the higher res image soon.
I usually don't self plug, but just today my long deliberated article on PLAN SSNs (09IIIB and 09V inclusive) was published.
It includes a summary of the predictions for what 09V may look like based on rumours... So we may see this tested quite quickly if the images are indeed present.

I dont think NN will be in a position to publish the images directly, but Janes will likely do so first in their coverage, and hopefully CSIS will also pick it up. All told, I have seen three images from two different providers which this article is based on.
Do you see whether the VLS tubes are individual ones (like on the 093B SSNs) or multipack ones (like on the Virginia SSNs from Block 3 onwards)?
We dont see any tubes yet, just a partially obscured (not clear if a tarp or some other cover) compartment where the hull cladding on top of the pressure hull is missing. Hence the caveat that it could be related to reactor work, although my sense is its indeed the VLS. It is a little distance from the sail, but there is also other "stuff" on top of the hull that may be work related equipment or imagery artifacts. Its pretty difficult to tell. Same reason for not being able to see the pump jet or dive planes clearly.
nice article , if the integrated electric propulsion system is included since the beginning, the 09V will definitely be the quietest ssn ever , also "damping" not "dampening"
