Wrong.

"Commercial used fuel rods are ... stored at 76 reactor or storage sites in 34 states."

"The spent fuel rods are still highly radioactive and continue to generate significant heat for decades. The fuel assemblies, which consist of dozens to hundreds of fuel rods each, are moved to pools of water to cool. They are kept on racks in the pool, submerged in more than twenty feet of water, and water is continuously circulated to draw heat away from the rods and keep them at a safe temperature.

Because no permanent repository for spent fuel exists in the United States, reactor owners have kept spent fuel at the reactor sites. As the amount of spent fuel has increased, the Nuclear Regulatory Commission has authorized many power plant owners to increase the amount in their storage pools to as much as five times what they were designed to hold. As a result, virtually all U.S. spent fuel pools have been “re-racked” to hold spent fuel assemblies at densities that approach those in reactor cores."

It's not just the ignorance; it's the arrogance that really puts us all at risk.
