The greatest near term threat to humanity is reactor fuel pond No. 4. International aid for the stabilization of the Fukushima-Daichi site is needed, to place all of its spent reactor fuel into dry, hardened storage casks. This will require about 244 additional casks at a cost of about $1 million per cask. To accomplish this goal, an international effort is required – something that Senator Ron Wyden (D-OR) has called for. As we have learned, despite the enormous destruction from the earthquake and tsunami at the Dai-Ichi Site, the nine dry casks and their contents were unscathed. This is an important lesson we should not ignore.
