Hualong One in Pakistan

Refering to the two construction sites in Karachi, Kanupp 2 (construction start 2015-08-20) and Kanupp 3 (construction start 2016-05-31), the PRIS database calls this "ACP-1000" and not "HPR1000" such as Fuqing 5 (construction start 2015-03-07). Is there a reason behind the IAEA's reluctance to call these two Pakistani reactors Hualong One?

What exactly is the technical difference between CNNC's ACP-1000 and the merged Hualong One model which also should have some CGN's ACPR-1000+ elements? --Gunnar (talk) 15:59, 3 October 2020 (UTC)

IAEA reluctance maybe that "Hualong One" is the marketing name for the two "merged" almost the same designs from CGN and CNNC, rather than an exact technical name. I used to believe CGN calls theirs HPR1000, but thought CNNC called their version something else, but a recent WNN article writes "Karachi 2 and 3 are the first export of China's Hualong One design, promoted on the international market as the HPR1000" which says HPR1000 is the international name for both CGN and CNNC versions. I think CGN HPR1000 is essentially the ACPR-1000+ with perhaps the core reconfigured a bit for the "Hualong One" merged standard core specification. I would guess the CNNC Hualong One changes from the ACP-1000 are pretty similar, mostly post Fukushima safety improvements. The ACPR-1000+ article says the improvements against the ACPR-1000 are "double containment to protect against external explosions and airplanes, improved seismic capability to 0.3 g, increased core thermal margins and improved operation systems ... gross power output has been increased to 1150 MWe". The merger made it all a bit confusing! It seems quite difficult finding a good source to pin all this down exactly. Hope this helps a bit :-) Rwendland (talk) 18:45, 3 October 2020 (UTC)

Although the two newer units at KANUPP are labelled in many press articles as Hualong One

* https://world-nuclear-news.org/Articles/Karachi-3-receives-operating-licence

the PRIS database says that Units 2 and 3 of the Karachi Nuclear Power Plant are designated as ACP-1000 and not as HPR1000. The latter is the model name for Fuqing 5, which was the first Hualong One unit built on the Chinese Mainland, and for all the following Hualong reactors.

* KANUPP-3 @ PRIS

If we look at the history of reactor series developed in China, cf. CNP / ACP nuclear reactors, the ACP-1000 was an advanced version of the CNNC development, which merged with the ACPR-1000 from CGN into the shared Hualong One design. Taking into account that the construction of KANUPP-2 began almost simultanously as FUQING-5, and the complexity of international reactor deals, I would raise the swag, that PRIS is right, and the press labelling of the two new units in Karachi as Hualong One is following rather a marketing campaign which cannot hold out against scientific scrutiny. --Gunnar (talk) 22:16, 28 August 2023 (UTC)

Chashma 5

I removed Chashma 5 from the page as I can find no references to it being under construction, just proposed. The World Nuclear Association is pretty authoritative on reactors under construction and it has no listing of it under its Pakistan page: https://www.world-nuclear.org/country/default.aspx/Pakistan Booshank (talk) 23:12, 11 January 2023 (UTC)
