Bechtel Corporation

I've added links on the blog page to represent both of Bechtel's general nuclear energy concerns; namely, its original design and contracting business, and its much more recent (2008) operation of both Bettis Atomic Power Laboratory and Knolls Atomic Power Laboratory which were formerly operated by Westinghouse and Lockheed-Martin. Knolls was originally operated by General Electric. Bechtel's next major project for the BMPC operation appears to be the A1B reactor plant for the next generation of aircraft carriers, to be known as the CVN-21 class.

There is a good description of Bechtel's history and operations to be found here.
