We are now within two months of what may be humankind's most dangerous moment since the Cuban Missile Crisis.

There is no excuse for not acting. All the resources our species can muster must be focussed on the fuel pool at Fukushima Unit 4.

Fukushima's owner, Tokyo Electric (Tepco), says that within as few as 60 days it may begin trying to remove more than 1,300 spent fuel rods from a badly damaged pool perched 100 feet in the air. The pool rests on a badly damaged building that is tilting, sinking and could easily come down in the next earthquake, if not on its own.

Some 400 tons of fuel in that pool could spew out more than 15,000 times as much radiation as was released at Hiroshima.

The one thing certain about this crisis is that Tepco does not have the scientific, engineering or financial resources to handle it. Nor does the Japanese government. The situation demands a coordinated worldwide effort of the best scientists and engineers our species can muster.

Why is this so serious?

We already know that thousands of tons of heavily contaminated water are pouring through the Fukushima site, carrying a devil's brew of long-lived poisonous isotopes into the Pacific. Tuna irradiated with fallout traceable to Fukushima have already been caught off the coast of California. We can expect far worse.

Tepco continues to pour more water onto the proximate site of three melted reactor cores it must somehow keep cool. Steam plumes indicate fission may still be going on somewhere underground. But nobody knows exactly where those cores actually are.

Much of that irradiated water now sits in roughly a thousand huge but fragile tanks that have been quickly assembled and strewn around the site. Many are already leaking. All could shatter in the next earthquake, releasing thousands of tons of permanent poisons into the Pacific.

The water flowing through the site is also undermining the remnant structures at Fukushima, including the one supporting the fuel pool at Unit Four.

More than 6,000 fuel assemblies now sit in a common pool just 50 meters from Unit Four. Some contain plutonium. The pool has no containment over it. It's vulnerable to loss of coolant, the collapse of a nearby building, another earthquake, another tsunami and more.

Overall, more than 11,000 fuel assemblies are scattered around the Fukushima site. According to long-time expert and former Department of Energy official Robert Alvarez, there is more than 85 times as much lethal cesium on site as was released at Chernobyl.

Radioactive hot spots continue to be found around Japan. There are indications of heightened rates of thyroid damage among local children.

The immediate bottom line is that those fuel rods must somehow come safely out of the Unit Four fuel pool as soon as possible.

Just prior to the 3/11/11 earthquake and tsunami that shattered the Fukushima site, the core of Unit Four was removed for routine maintenance and refueling. Like some two dozen reactors in the US and too many more around the world, the General Electric-designed pool into which that core now sits is 100 feet in the air.

Spent fuel must somehow be kept under water. It's clad in zirconium alloy which will spontaneously ignite when exposed to air. Long used in flash bulbs for cameras, zirconium burns with an extremely bright hot flame.
