In a 2009 report comparing costs of dumping high-level radioactive wastes at Yucca Mountain versus regional "centralized interim storage" (parking lot dumps) versus very long term on-site storage at nuclear power plants (centuries), the U.S. Government Accountability Office admitted (on page 29) that "In fact, reprocessing facilities could be built near or adjacent to centralized facilities to maximize efficiencies." With President Obama's Blue Ribbon Commission on America's Nuclear Future advocating parking lot dumps, and Energy Secretary Chu advocating reprocessing, the risks of weapons proliferation, environmental destruction, health damage, and astronomical costs associated with reprocessing linger on.
