“In the pre-dawn hours of July 28, 2012, they hiked a wooded ridge, cut through four fences, and splashed human blood and spray-painted biblical messages on the outside of the building that warehouses an estimated 400 tons of highly enriched uranium — enough to fuel 10,000 nuclear bombs.”

“The unprecedented intrusion shut down operations at the site for two weeks, led to four congressional hearings and exposed a glitch-ridden security system that cost $150 million a year. The National Nuclear Security Administration, a semiautonomous agency within the Energy Department, responded to the break-in with a variety of security measures, from installing 2,850 linear feet of concertina wire to requiring that malfunctioning security tools be repaired within 24 hours.

Babcock & Wilcox Technical Services Y-12, the site’s private contractor for management and operations, was docked $12.2 million in fees and lost a 10-year contract worth $23 billion to manage both Y-12, where uranium is stored and processed, and the Pantex Plant in Amarillo, Tex., where nuclear weapons are assembled and disassembled.” – Washington Post
