ap1000 Definition and 1 Threads
The AP1000 is a nuclear power plant designed and sold by Westinghouse Electric Company. The plant is a pressurized water reactor with improved use of passive nuclear safety and many design features intended to lower its capital cost and improve its economics.
The design traces its history to the Westinghouse 4-loop SNUPPS design, which was produced in various locations around the world. (Note: System 80 was a similar vintage nuclear steam supply system made by Combustion Engineering). Further development of the 4-loop reactor and the ice-condenser containment initially led to the AP600 concept, with a smaller 600 to 700 MWe output, but this saw limited interest. In order to compete with other designs that were scaling up in size in order to improve capital costs, the design re-emerged as the AP1000 and found a number of design wins at this larger size.
Twelve AP1000s are currently in operation or under construction. Four are in operation at two sites in China, two at Sanmen Nuclear Power Station and two at Haiyang Nuclear Power Plant. As of 2019, all four Chinese reactors were completed and connected to the grid, and as of 2024, 6 more are under construction. Two are in operation at the Vogtle Electric Generating Plant in the US, with Vogtle 3 having come online in July 2023, and Vogtle 4 in April 2024. Construction at Vogtle suffered numerous delays and cost overruns at Vogtle and V.C. Summer led to Westinghouse's bankruptcy in 2017. Construction of the two reactors at the Virgil C. Summer Nuclear Generating Station was cancelled in 2017 following Westinghouse's bankruptcy.
Nineteen more AP1000s are currently being planned, with 6 in India, 9 in Ukraine, 3 in Poland, and 1 in Bulgaria.
China is currently developing more advanced versions and owns their patent rights. The first AP1000 began operations in China at Sanmen, where Unit 1 became the first AP1000 to achieve criticality in June 2018, and was connected to the grid the next month. Further builds in China will be based on the modified CAP1000 and CAP1400 designs.
