Story here of CNNC developing N36 Zirconium based alloy and CF3 nuclear fuel assemblies for Hualong-1 plant. CNNC has developed CF2 and CF3 nuclear fuel and exported them also to Pakistan. First 6000 N36 tubes were produced in 2018/11. Product has gone up 30x by 2024. Yield from tube billet to finished pip rose from 45% to 75% (close to international standards). America developed zircaloy-4 back in 60s and this was kept in house. Now, N36 has finally allowed China to catch up in this alloy. Additional work was required to produce Zirconium alloy cladding tubes for heavy water reactor (totaling > 4000 units by 2024/6). Higher standard required here due to high diameter to thickness ratio for HWR. By end of 2025, 西部新锆 got contract for a million HWR cladding tubes, !70% of domestic demand for this product. 西部新锆 is now working on next generation N45 alloy. Linglong-1 is validating N36 short tube. 西部新锆 was relying on single supplier for nuclear grade zirconium sponge, but it got more suppliers by 2024. It ahs now exported Zirconium alloy material samples to Argentina, CNNC's first such export.
To be fair, that’s not overcapacity at all. If anything , China is just playing catching up in nuclear production . Afterall Chinas current nuclear production is barely equal to France (a country of 60million) and who has lost much of its industrial power. Even with all the nuclear plants in construction today in China if all of them become operational they will just match the US CURRENT NUCLEAR production . This shows that China still has a long way to go. Since China is a 1.4billion country and with basically the worlds factory, so her production in many ways should be at least twice that of the US at minimum . Maybe when they get to over 3/4 times that of th US then we can indeed start talking about overcapacity like today in solar industry where China has clearly had a problem of overcapacity which the government has been trying hard to tame and cut those excess production , but still haven’t been able to succeed until now(it’s getting better though). So the nuclear sector is clearly far from that.
I believe in terms of GW, China is ahead of US nuclear production
US has more reactors, but they are often dinky (1 or 2 unit plants) and at this point, old
huge expansion in Hualong-1 happening right now with reactors finally reaching commercialization stage. It's taken a few years, which is normal since the construction time of 5 to 6 years is about as fast as you can get for 1.2GW NPPs
What do we know about the CAP-1700 and CAP-2100?
CAP-2100???? We are basically just building CAP-1400 and Hualong-1 right now.
The CAP-1700 was in conceptual design and CAP-2100 was being considered if the passive cooling system could be scaled up. So I was wondering if there had been any news regarding that.
Not only that, China is actively working on the carbon footprint of its coal for power generation.
Case in point.

Generally speaking, as far as power generation is concerned, China is moving everywhere at once. Because they can, and because they have to. Nuclear is a very important pylon on this, but the idea that China is "not doing enough" is ludicrous.
"SINAP aims for a 2 MWt pilot plant (TMSR-LF1) by 2018, a 10 MWt experimental reactor (TMSR-LF2) by 2025 and a 100 MWt demonstration plant (TMSR-LF3) with full electrometallurgical reprocessing by 2035, followed by 1 a GW demonstration plant."
So, it seems that TMSR-LF4 will be a Giga Watt scale reactor, the article claims thermal but given that since TMSR-LF3 has been more or less confirmed that it will be 100MWe it's more likely than not that it will be 1GWe for TMSR-LF4. Another really exciting thing is the on-site reprocessing. One significant caveat is that the articles themselves are old, from 2016.
From my understanding:
TMSR-LF1 2MWt, no electricity output (0MWe)
TMSR-LF2 60MWt, 10MWe
TMSR-LF3 ?MWt, 100MWe, on-site reprocessing
TMSR-LF4 ?MWt, 1000MWe, on-site reprocessing
