For decades, the Energy Department—which manages the weapons complex through the National Nuclear Security Agency (NNSA)—has not been able to reconcile competing objectives at the 811-acre Y-12 site, whether they involve storage areas for HEU and other fissile materials, the restarting of old weapons facilities, environmental cleanup, the building of new weapons facilities, or the downsizing of the site. As a result, costs have significantly increased, and long-standing problems have continued, unresolved, for years that have run into decades. For every dollar spent to maintain and modernize the US nuclear weapons stockpile, nearly three dollars is spent “to provide the underlying infrastructure” for maintenance and modernization at Y-12.

Long-term secrecy and isolation have created a dangerous form of hoarding at Y-12; a panoply of severe hazards continues to build up, constantly awaiting ever more costly mitigation in the future. But the stark reality is that there are no more cans to kick down the road. Y-12 has inexorably caught up with its future. Its environmental and security problems are too threatening to leave unaddressed, and questions about its mission will have to be answered definitively in an age of budgetary austerity and relatively little need for new nuclear weapons…….

During its heyday, Y-12 produced some 1,000 CSAs per year. Now, its annual production capacity has dwindled to less than 100. Though the NNSA declares that Y-12 has multiple missions, including non-proliferation efforts that involve the downblending of HEU and the provision of fuel for the Navy’s nuclear-powered submarines, nearly 99 percent of its budget comes from funds dedicated to maintain the US nuclear weapons stockpile. More than anything, Y-12 serves to stockpile thousands of CSAs from discarded nuclear weapons, as well as depleted uranium, lithium, and other hazardous chemicals……..  the Government Accountability Office finds that “NNSA’s decision to retain many CSAs … poses significant challenges to Y-12’s ability to plan its disassembly workload.” Although exact numbers have been classified since the 1990s, there are likely several thousand excess CSAs, containing hundreds of tons of HEU, awaiting dismantlement at Y-12. ……

Around New Year’s Eve of 1996, a long-awaited vulnerability assessment of HEU storage at Energy Department sites was released. Y-12 had the most significant problems. Even though fires posed the greatest danger of radiation and chemical exposure to workers and the public, buildings, mostly constructed in the 1940’s, had deteriorated and had insufficient or non-existent fire-protection systems, despite the very real possibility of a truly catastrophic fire and resulting release of radiation. It wasn’t until 14 years later that a replacement facility for the aged wooden structure serving as the main HEU storage warehouse was opened; it cost five times the original construction estimate. That facility gained notoriety in August 2012, after nonviolent peace protestors, including an 84-year-old nun, penetrated its security barriers……..

From 1997 to 2006, there were 21 fires and explosions at Y-12 involving electrical equipment, glove boxes, pumps, waste containers, and nuclear and hazardous chemicals. Several resulted in worker injuries and destruction of property.  ………..  In March 2014, a large portion of a concrete ceiling collapsedin a building that was once part of the weapons operation. It was a near miss: Foot-long concrete pieces bounced onto walkways and an area where welders had been working just a day before. …..

In April 2014, the NNSA released a “red team” report, led by the director of Oak Ridge National Laboratory, on the troubled UPF. The team’s most significant recommendation was to rethink a basic, “big-box” approach that would create a UPF to serve multiple functions in one structure. Instead, to hold the line at an estimated $6.5 billion for design and construction costs, the team recommended going back to the drawing board to effectively reduce the size and scope of the project. Meanwhile, in recognition of the growing hazards associated with a deteriorating infrastructure for storing “materials at risk,” the team recommended that greater emphasis should be given to safe consolidated storage of materials, deferred maintenance, and safety upgrading……….

Regardless of the wisdom of or need for an asteroid-protection program, the future of Y-12 should be focused on earthly realities: cleaning up the environment, decontamination and decommissioning of facilities, stabilizing nuclear and other hazardous materials, and the dismantlement of a large excess stockpile of weapons components. There is a very real need to replace the collapsing infrastructure at Y-12 with facilities that can accomplish these goals.

Protecting the planet from asteroids is a poor rationale for failing to deal with the environmental, safety, financial, and health challenges the Y-12 site poses to the people who live in the area, and to the country as a whole.  http://thebulletin.org/y-12-poster-child-dysfunctional-nuclear-weapons-complex7361
