has been progressively merging its

Daya Bay

History
The bay was a hideo ...
with 157 fuel assemblies, but went through different development processes (CNNC's ACP-1000 has a more domestic design with 177 fuel assemblies while CGN's ACPR-1000 is a closer copy with 157 fuel assemblies).
In early 2014, it was announced that the merged design was moving from preliminary design to detailed design. Power output will be 1150 MWe, with a 60-year design life, and would use a combination of passive and active safety systems with a double containment. CNNC's 177 fuel assembly design was retained.
Initially the merged design was to be called the ACC-1000,
but ultimately it was named Hualong One. In August 2014 the Chinese nuclear regulator review panel classified the design as a
Generation III reactor design, with independently owned intellectual property rights.
As a result of the success of the merger, ACP-1000 and ACPR-1000 designs are no longer being offered.
After the merger, both companies retain their own supply chain and their versions of the Hualong One will differ slightly (units built by CGN will retain some features from the ACPR1000) but the design is considered to be standardised. CNNC version emphasizes more passive safety due to influence from Westinghouse AP1000, with increased containment volume and two active safety trains, while CGN version has three active safety trains due to influence from Areva EPR. Some 90% of its components will be made domestically.
The Hualong One power output will be 1170 MWe gross, 1090 MWe net, with a 60-year design life, and would use a combination of passive and active safety systems with a double containment.
[ It has a 177 assembly core design with an 18-month refuelling cycle. The power plant's utilisation rate is as high as 90%. CNNC has said its active and passive safety systems, double-layer containment and other technologies meet the highest international safety standards.
According to CNNC, the Hualong One has a construction cost of CNY17,000 per kW.
A the end of August 2014, Chinese regulators were satisfied that Hualong One was a Generation III design and that intellectual property rights were fully held in China.]
Chinese media reports that all core components are manufactured in China and that 17 universities and research institutions, 58 state-owned enterprises and over 140 private firms across China worked on Hualong One's development to ensure all core components were able to be produced domestically.
EU approval
In November 2021, the European Utility Requirements (EUR) organisation formally certified the Hualong One (HPR1000) as compliant after a four-step process which began in August 2017. The requirements covered a broad range of conditions for nuclear power plants to operate efficiently and safely.
UK approval
In February 2022, UK regulators announced that the Hualong One (HPR1000) had passed the four-step Generic Design Assessment (GDA) which started in August 2017 and was thus suitable for construction in the UK, possibly in the Bradwell B nuclear power station
Bradwell B is a proposed nuclear power station at Bradwell-on-Sea in Essex, put forward by China General Nuclear Power Group (CGN). If constructed, the site will provide 2,200 MWe of nuclear power from two UK HPR1000 reactors developed by CGN and ...

(ONR) started their Generic Design Assessment process for the Hualong One, expected to be completed in 2021, in advance of possible deployment at the Bradwell nuclear power station site.
On 16 November 2017, the ONR and the Environment Agency announced they are progressing to the next phase of their Generic Design Assessment of the UK HPR1000 reactor.
Step 2 formally commenced on this day and is planned to take about 12 months.
The targeted timescale for the UK HPR1000 GDA process is about five years from the start of Step 1.
Hualong Two
CNNC plans to start building a follow-on version, named Hualong Two, by 2024. It will be a more economical version using similar technology, reducing build time from 5 years to 4, and reducing costs by around a fourth from 17,000 yuan per kW to 13,000 yuan per kW.
