The AP1000 design traces its history to two previous designs, the AP600 and the System 80.. The System 80 design was created by Combustion Engineering and featured a two-loop cooling system with a single steam generator paired with two reactor coolant pumps in each loop that makes it simpler and less expensive than systems which pair a single reactor coolant pump with a steam generator in each ...

A report evaluating the AP1000 reactor design was written by the Edinburgh Energy and Environment Consultancy, commissioned by Radiation Free Lakeland. [25] The report criticises the design, saying that "The AP1000 reactor design is not fit for purpose and so should be refused a Design Acceptance Confirmation (DAC) and Statement of Design ...
The company's main product is the AP1000, a modern pressurized water reactor (PWR) design with many passive safety features and modular construction intended to lower construction time and cost. Twelve AP1000 reactors are currently in operation with a further nineteen in various stages of planning.
Hot testing of Sanmen 1 was completed in June 2017, and fuel loading started on 25 April 2018. It subsequently became the first AP1000 reactor in the world to achieve first criticality at 2:09 AM on 21 June 2018, [19] and was connected to the grid on 30 June 2018. [20] Sanmen Unit 1 entered into commercial operation on 21 September 2018. [21]
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. [5] It has a 177 assembly core design with an 18-month refuelling cycle. The power plant's utilisation rate is as high as 90%.
In November 2006, State Power Investment Corporation (SPIC) introduced the AP1000, a third-generation pressurized water reactor design, from the U.S. company Westinghouse Electric Corporation. [citation needed] Since then China built four AP1000 units, two in the Sanmen Nuclear Power Station, and another two in the Haiyang Nuclear Power Plant.
The plant is owned by CGN Huizhou Nuclear Power Co. CGN originally planned to have AP1000 light water reactors, but later changed plans to the Hualong One design. [1] Approval for the plant was granted in February 2019 and first concrete for Unit 1 was poured in December 2019. Approval for units 3 and 4 was granted in December 2023. [2]
