Let's talk about nuclear plant manufacturing first
The "latest and greatest" nuclear plant designs coming out of Westinghouse is the AP1000.
The first 4 of these are going to China
and construction has only just started with first power-up slated for 2013.
Two in the United Stated are planned for construction in the state of Georgia
On August 15, 2006, Southern Nuclear formally applied for an Early Site Permit (ESP) for two additional units. The ESP will determine whether the site is appropriate for additional reactors, and this process is separate from the Combined Construction and Operating License (COL) Application process. On March 31, 2008, Southern Nuclear announced that it had submitted an application for a COL, a process which will take at least 3 to 4 years. On April 9, 2008, Georgia Power Company reached a contract agreement for two AP1000 reactors designed by Westinghouse (owned by Toshiba) and the Shaw Group (Baton Rouge, LA). The contract represents the first agreement for new nuclear development since the Three Mile Island accident in 1979, and received approval from the Georgia Public Service Commission (PSC) on March 17, 2009. As stated by a Georgia Power spokesperson Carol Boatright: "If the PSC approves, we are going forward with the new units."[
