Mitsubishi said in a news release that it will also help Energy Future prepare its application for the new plant. Last year, TXU told the NRC it would file the application in mid-2008. Since then, the power company has been purchased by private equity companies and changed its name.
Energy Future spokesman Tom Kleckner said the company isn't ready to give a more exact date for submitting the application.
He added that Energy Future hopes to have two new 1,700-megawatt reactors online around 2020. The NRC has encouraged manufacturers to apply for standard design certification to speed the process of building reactors.
That way, when a power company chooses a standard design, the NRC can skip reviewing the design itself and concentrate on the location of the plant and the operations.
In the past, the U.S. nuclear industry had no standard designs, and the NRC's process of certifying a plant took years.
