**A Washington Post "Notable Nonfiction Book of 2016"** ON A TRANQUIL SUMMER NIGHT in July 2012, a trio of peace activists infiltrated the Y-12 National Security Complex in Oak Ridge, Tennessee. Nicknamed the “Fort Knox of Uranium,” Y-12 was supposedly one of the most secure sites in the world, a bastion of warhead parts and hundreds of tons of highly enriched uranium—enough to power thousands of nuclear bombs. The three activists—a house painter, a Vietnam War veteran, and an 82-year-old Catholic nun—penetrated the complex’s exterior with alarming ease; their strongest tools were two pairs of bolt cutters and three hammers. Once inside, these pacifists hung protest banners, spray-painted biblical messages, and streaked the walls with human blood. Then they waited to be arrested. WITH THE BREAK-IN and their symbolic actions, the activists hoped to draw attention to a costly military-industrial complex that stockpiles deadly nukes. But they also triggered a political and legal firestorm of urgent and troubling questions. What if they had been terrorists? Why do the United States and Russia continue to possess enough nuclear weaponry to destroy the world several times over? IN ALMIGHTY, WASHINGTON POST REPORTER Dan Zak answers these questions by reexamining America’s love-hate relationship to the bomb, from the race to achieve atomic power before the Nazis did to the solemn 70th anniversary of Hiroshima. At a time of concern about proliferation in such nations as Iran and North Korea, the U.S. arsenal is plagued by its own security problems. This life-or-death quandary is unraveled in Zak’s eye-opening account, with a cast that includes the biophysicist who first educated the public on atomic energy, the prophet who predicted the creation of Oak Ridge, the generations of activists propelled into resistance by their faith, and the Washington bureaucrats and diplomats who are trying to keep the world safe. Part historical adventure, part courtroom drama, part moral thriller, Almighty reshapes the accepted narratives surrounding nuclear weapons and shows that our greatest modern-day threat remains a power we discovered long ago.

The National Nuclear Security Administration (NNSA) a separately organized agency within the U.S. Department of Energy (DOE) is responsible for providing the Nation with nuclear weapons and ensuring that those nuclear weapons remain safe, secure, and reliable. As one of the DOE major production facilities, the Y-12 National Security Complex has been DOE's primary site for enriched uranium processing and storage, and one of the manufacturing facilities for maintaining the U.S. nuclear weapons stockpile. In response to the end of the Cold War and changes in the world's political regimes, the emphasis of the U.S. weapons program has shifted dramatically over the past few years from developing and producing new weapons to dismantlement and maintenance of a smaller, enduring stockpile. The ''Stockpile Stewardship and Management Programmatic Environmental Impact Statement'' [SSM PEIS], DOE/EIS-0236, issued in September 1996, evaluated alternatives for maintaining the safety and reliability of the nuclear weapons stockpile without underground nuclear testing or production of new-design weapons. In the SSM PEIS Record of Decision (ROD), DOE decided to maintain the national security missions at the Y-12 National Security Complex, but to downsize Y-12 consistent with reduced requirements. These national security missions include (1) maintaining the capability and capacity to fabricate secondaries, limited life components, and case parts for nuclear response; (2) evaluating components and subsystems returned from the stockpile; (3) storing enriched uranium that is designated for national security purposes; (4) storing depleted uranium and lithium parts; (5) dismantling nuclear weapons secondaries returned from the stockpile; (6) processing uranium and lithium (which includes chemical recovery, purification, and conversion of enriched uranium and lithium to a form suitable for long-term storage and/or further use); and (7) providing support to weapons laboratories. During the same time period as the SSM PEIS, DOE also prepared the ''Storage and Disposition of Weapons-Usable Fissile Materials Programmatic Environmental Impact Statement'' [S & D PEIS], DOE/EIS-0229, which was issued in December 1996. This S & D PEIS evaluated alternatives for the long-term storage of fissile material. In the S & D PEIS ROD, DOE decided that Y-12 would also store surplus enriched uranium pending disposition.

In the summer of 2012, in the dead of night, three peace activists- a drifter, an 82-year-old nun, and a house painter- penetrated the exterior of Y-12 in Tennessee, supposedly one of the most secure nuclear-weapons facilities in the United States. What if they had been terrorists armed with explosives, intent on mass destruction? That nightmare scenario underlies the government’s response to the intrusion. THE PROPHETS OF OAK RIDGE is the story of two competing worldviews, of conscience vs. court, of fantasy vs. reality, of history vs. the future.
