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 ...
In June 2014, China First Heavy Industries completed the first domestically produced AP1000 reactor pressure vessel for the second AP1000 unit. [13] The units were originally projected to begin operation in 2014 and 2015. In April 2015, a start date of 2016 was projected for both. [14] One month later, the start date was put back to 2017.
Westinghouse Electrique France is located in Orsay and Manosque near Marseille (engineering development). As of 2014, about 400 employees are part of Westinghouse in France. Westinghouse owns a nuclear fuel fabrication plant at Västerås, Sweden which has provided nuclear fuel for Russian VVER-1000 nuclear reactors.
Gundersen questioned the safety of the Westinghouse AP1000, a proposed third-generation nuclear reactor and has expressed concerns about the operation of the Vermont Yankee Nuclear Power Plant. He served as an expert witness in the investigation of the Three Mile Island accident [ 6 ] and has provided commentary on the Fukushima Daiichi nuclear ...
The AP1000 has fewer safety related components then a Westinghouse generation II design. Passive means there are no active components (pumps) are required to move the water through the core, water movement is by natural convection processes, i.e., heat rises and cold descends.
In August 2014 Westinghouse resumed the AP1000 assessment, after Toshiba and ENGIE purchased NuGeneration and announced plans to develop Moorside Nuclear Power Station with 3 AP1000s. In November 2016 the ONR noted there was a "very large amount of assessment to complete with issues still emerging".

On 29 March 2017, parent company Toshiba placed Westinghouse Electric Company in Chapter 11 bankruptcy because of US$9 billion of losses from its nuclear reactor construction projects. The projects responsible for this loss are mostly the construction of four AP1000 reactors at Vogtle in Georgia and V. C. Summer in South Carolina. [96]
