By the end of the year, Chinese companies will begin international marketing of a 1,400 megawatt power reactor based largely on the Westinghouse AP1000.In return for the right to sell the AP1000 in China, Westinghouse agreed to help Chinese firms use its generation III pressurized water reactor as a template to develop domestic Chinese designs. One is the CAP1400, which is slated for construction in Rongcheng this year. State Nuclear Power Technology Co. President Gu Jun announced Friday that the coming months would also see the beginning of efforts to export the CAP1400, People's Daily reported.The marketing will take place in cooperation with Westinghouse, according to the Communist Party newspaper, and the Pennsylvania-based Toshiba subsidiary might also generate business from sales of CAP1400s abroad. In the same press conference, SNPC Chairman Wang Binghua also announced that development of a larger reactor called the CAP1700 would begin this year.
Just another example of China saying "pay to play". They take tech from the US in order for the US to sell there. After they master the technology, they kick the US out.
It's the same way countries have advanced with such technology for awhile, China has just been especially aggressive about it.
It's also a very easy game to play, because if Westinghouse didn't agree to technology transfer, they would have gone to France. If France turned them down they would have bought up whatever nuclear IP Germany has (and is not using), if Germany turned them down they would have gotten the technology from Russia. At least this way Westinghouse is getting back the development cost and getting some experience with the design (which will flow back to the US).
It's also a good thing the Chinese are extending a design that starts off passively safe (the AP1000) so nuclear power won't get stopped by another Chernobyl. China exporting the CAP1400 around the world does pretty much spell the death of Russian nuclear reactor exports, since they will lose their only advantage (cost). Now China will be the go to for cheap nuclear power and France/USA will be the suppliers for those countries that don't trust the PRC on safety.
In Finland even the AP1000 is unlicensable because our regulator (STUK) considers it to be too powerfull for the core melt IVR-system Westinghouse originally developed for the AP600. And now the chinese intend to scale up this same design even further - as far as I understand still without substituting the questionable IVR-system with a reliable core catcher. "Interesting" SAM-strategy indeed - and even more interesting to see if there really would be export market for a reactor with such a recless critical safety "feature" (I would say: bug).
