Most of them are going to be using the latest iteration of some tried-and-true series of reactors from another country. Russia is exporting the VVER-1200, Korea is exporting their APR-1400, and China is looking to export their ACPR-1000 and large components of American, Japanese, and European reactors.
The common thread here is that all of these are very conventional, directly descended from designs that have seen extensive service and have an excellent record of reliability. You're not going to see newbie countries screwing up the designs. (You might see them mess up the operations.)
