The National Park Service runs three different sites related to the WW II Manhattan Project. The one on the Hanford Nuclear Reservation in southeast Washington was the first full-scale nuclear reactor in the world. The B Reactor features hundreds of nozzles capping the metal process tubes on the reactor face and even a mint-green control room with all its 40s-era instrument panels. But it’s hearing about the human stories of struggle that make the history come alive. Sept. 26 marks 80 years since the B-reactor first went online. We get a tour from Terri Andre, a volunteer docent at the Manhattan Project National Historical Park at Hanford.
