Manhattan project

The other day we were talking about spies and what motivates them to undertake dangerous missions and Klaus Fuchs and Manhattan project came to our minds:

The bomb factory for the Manhattan project was in Hanford, Washington. Why was that location chosen? US army general Leslie Groves, who had directed construction of the Pentagon became head of what had been obliquely named the Manhattan Project, had spent part of his early years growing up at Fort Lewis, near Tacoma, Washington. As he looked for a site in the West remote from population centers and with a generous supply of electricity to run the bomb factories and water to cool the reactors. Hanford, downriver from the just-completed Grand Coulee Dam and adjacent to the Columbia River, fit the bill.
