We didn't really need another argument that questions the safety of nuclear technology, but scientists working at Yucca Mountain in Nevada, the proposed national repository for nuclear waste, have given us one. The pressure to make the controversial site work led some scientists there to fudge the data for their safety studies in order to satisfy superiors.
On the other hand, nuclear wastes now mostly sit next to power plants in so-called cooling pools, pools that are vulnerable to attack and overloaded in some cases. What a mess! And, they call this clean energy!
UPDATE: The New York Times reports on yet another study that finds current methods for storing nuclear waste at power plants make it vulnerable to attack.
