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 ...

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 the AP1000 design, the liner and the concrete are separated, and if the steel rusts through, "there is no backup containment behind it" says Gundersen. [12] If the dome rusted through the design would expel radioactive contaminants and the plant "could deliver a dose of radiation to the public that is 10 times higher than the N.R.C. limit ...
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]
Construction of unit 2 started in June 2010, at that time the fourth Chinese AP1000 project together with the two units of the Sanmen NPP. [9] Commercial operation began in January 2019, after having completed a full-power test run for a week (168 hours). Both units will provide together about 20 TWh of electricity to the grid of Shandong ...
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 System 80+ was developed into the Korean OPR-1000 and later APR-1400, [3] and contributed design features to the AP1000. [ 4 ] The NRC has certified the System 80+ for the U.S. market, but Westinghouse ceased actively promoting the design for domestic sale, prior to their bankruptcy.
