If the spent rods at Fukushima go critical, that will be the end of nuclear fission power. Here in the US we are in an even worse position in many of our reactors. And, given the number of reactors, Murphy's Law is for real.

Nationally, the nationÂ’s 104 nuclear power plants are now storing some 63,000 metric tons of spent fuel rods, according to 2010 numbers compiled by the Nuclear Energy Institute.
In New England, the four operating nuclear power plants are storing at least 2,900 metric tons of spent fuel, according to current figures provided by two plants and 2002 data available for two others, which is the most recent available. The Indian Point Energy Center nearby in New York state is storing at least 903 metric tons of spent fuel.
New England’s plants have re-racked their spent-fuel storage pools many times over the last few decades. In many cases, the stored spent-fuel rods are now packed closer together than ever before – nearly as close as they were positioned inside the reactor.
The storage pool at Vermont Yankee Nuclear Power Station was originally licensed to hold 600 spent fuel assemblies. There are now 2,935 assemblies in the pool, or 932 metric tons of radioactive waste.
At Millstone Nuclear Power Station in Waterford, the pool at the Unit 3 reactor was originally licensed to hold 756 assemblies. It now holds 1,040 assemblies, or 449 metric tons of waste, and is licensed to handle up to 1,860 assemblies.
Millstone’s Unit 2 reactor was originally licensed to hold 677 spent fuel assemblies. It now holds 909 assemblies, or 304 metric tons, and is licensed to hold 1,346 assemblies. · The Pilgrim Nuclear Power Generating Station in Massachusetts currently holds 2,918 fuel assemblies. Its original license allowed 880 fuel assemblies, according to NRC documents. The license was later updated to allow for 3,859 assemblies
Dry case storage is much safer, but more expensive. However, hardly as espensive as what Japan is experiancing right now.
