The nation's electric utitlies have collectively paid the U.S.  Department of Energy $31 billion to "take away" their radioactive waste.  But of course, there is still nowhere for it to go - a problem that is  likely to persist indefinitely. Given the lack of a waste dump or other  "solution," the utilities are suing the DOE to try to suspend fees they  pay the   government for nuclear waste storage. But the DOE wants to  keep collecting its annual fees because, as the agency telllingly admits  to Automated Trader, "they'll eventually develop a long-term storage   solution. And when they do, it's likely to be expensive."
