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 ...

During start-up and pre-operational testing in February 2023 the plant's cooling system suffered from unexpected vibrations. Measures were taken to remedy the problem. The time-plan was set back so that the beginning of regular service was expected for May or June 2023. [63] On March 6, 2023, Vogtle Unit 3 reached criticality for the first time.
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.
In November 2022, the Polish government selected the Westinghouse AP1000 reactor design for the proposed nuclear power station. In October 2023, the Pomeranian Voivodeship regional authority authorised preparatory work at the site; a construction permit would still be required later. [5]
The original plan by NuGeneration, a British subsidiary of Toshiba-owned Westinghouse Electric Company, had the station coming online from 2024 with 3.4 GW of new nuclear capacity, from three AP1000 reactors. Work up to 2018 would include acquiring the site licence, the development consent order, and other required permits and permissions to ...
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 design has been scaled up and improved with the AP1000. Certification testing and analysis of the AP600 and AP1000 reactor designs for Westinghouse were conducted at the APEX facility at Oregon State University. The one-quarter scale reduced pressure integral system certified the passively safe systems that cool the reactor core using ...
