If you can guarantee two brand new gigawatt scale nuclear power plants for $44b then you can raise that money easily. The problem isn’t the access to money that prevents it. It’s that the the number of NRC approved reactors built since it came into existence is countable on your fingers.

I’m not even kidding. If you can pass the regulation, environmental, land permits, local opposition etc. you will be a hundred millionaire maybe a billionaire.
