There’s more cesium in that [Unit 4] fuel pool than in all 800 nuclear bombs exploded above ground…

But of course it would happen all at once.

It would certainly destroy Japan as a functioning country…

Move south of the equator if that ever happened, I think that’s probably the lesson there.

AlterNet asked Sen. Wyden if he considers the spent fuel at Fukushima Daiichi a national security threat.

In a statement released by his office, Wyden replied, “The radiation caused by the failure of the spent fuel pools in the event of another earthquake could reach the West Coast within days. That absolutely makes the safe containment and protection of this spent fuel a security issue for the United States.”

[Robert Alvarez – a nuclear expert and a former special assistant to the United States Secretary of Energy] agrees, saying, “My major concern is that this effort to get that spent fuel out of there is not something you should be doing casually and taking your time on.”

Yet Tepco’s current plans are to hold the majority of this spent fuel onsite for years in the same elevated, uncontained storage pools, only transferring some of the fuel into more secure, hardened dry casks when the common pool reaches capacity.

Nuclear waste experts … charge that the NRC is letting this threat [of the Fukushima fuel pools] fester because acknowledging it would call into question safety at dozens of identically designed nuclear power plants around the U.S., which contain exceedingly higher volumes of spent fuel in similar elevated pools outside of reinforced containment.

In an interview with AlterNet, Alvarez … said that the Japanese government, Tepco and the U.S. NRC are reluctant to say anything publicly about the spent fuel threat because “there is a tendency to want to provide reassurance that everything is fine.”

“The U.S. government right now is engaged in its own kabuki theatre to protect the U.S. industry from the real costs of the lessons at Fukushima,” Gunter said. “The NRC and its champions in the White House and on Capitol Hill are looking to obfuscate the real threats and the necessary policy changes to address the risk.”

There are 31 G.E. Mark I and Mark II boiling water reactors (BRWs) in the U.S., the type used at Fukushima. All of these reactors, which comprise just under a third of all nuclear reactors in the U.S., store their spent fuel in elevated pools located outside the primary, or reinforced, containment that protects the reactor core. Thus, the outside structure, the building ostensibly protecting the storage pools, is much weaker, in most cases about as sturdy, experts describe in interviews with AlterNet, as a structure one would find housing a car dealership or a Wal-Mart.
