A letter from U.S. Department of Energy Secretary Steven Chu to White House Office of Management and Budget Director Peter Orszag seems  to indicate a difference in positions as to how quickly the Yucca Mountain, Nevada high-level radioactive waste dumpsite should be phased out. Although President Obama and Energy Secretary Chu have made clear time and time again that Yucca is no longer an option for high-level radioactive waste disposal, the proposed repository's construction and operating license application proceeding before the U.S. Nuclear Regulatory Commission has been allowed to continue (in fact an oral hearing will be held at the end of this month in Las Vegas), raising the specter that the supposedly cancelled dump could come back to life someday under the right political circumstances. In the meantime, the State of Nevada Agency for Nuclear Projects, Timbisha Shoshone Indian Tribe, and other dump opponents must remain vigilant until the final nail has been pounded down on the dump's coffin lid.
