Ehhhh Westinghouse bankrupted Westinghouse. They decided they were going to cut Bechtel out of the project and build VC summer by themselves. Pocketing the "savings". Problem is, the way things had worked for decades before is Westinghouse does the design and Bechtel does the construction. They couldn't cut it on their own and it destroyed the company. They let the financial dinks speak louder than the engineers and payed for it dearly.

There's a chance things would have gone much different if they didn't try to take on a work scope completely out of their league.
