Each uncovered rod emits enough radiation to kill someone standing nearby in a matter of minutes. A conflagration could force all personnel to flee the site and render electronic machinery unworkable.
According to Arnie Gundersen, a nuclear engineer with forty years in an industry for which he once manufactured fuel rods, the ones in the Unit 4 core are bent, damaged and embrittled to the point of crumbling. Cameras have shown troubling quantities of debris in the fuel pool, which itself is damaged.
The engineering and scientific barriers to emptying the Unit Four fuel pool are unique and daunting, says Gundersen. But it must be done to 100% perfection.
Should the attempt fail, the rods could be exposed to air and catch fire, releasing horrific quantities of radiation into the atmosphere. The pool could come crashing to the ground, dumping the rods together into a pile that could fission and possibly explode. The resulting radioactive cloud would threaten the health and safety of all of us.
Chernobyl's first 1986 fallout reached California within 10 days. Fukushima's in 2011 arrived in less than a week. A new fuel fire at Unit 4 would pour out a continuous stream of lethal radioactive poisons for centuries.
Former Ambassador Mitsuhei Murata says full-scale releases from Fukushima "would destroy the world environment and our civilization. This is not rocket science, nor does it connect to the pugilistic debate over nuclear power plants. This is an issue of human survival."
Neither Tokyo Electric nor the government of Japan can go this alone. There is no excuse for deploying anything less than a coordinated team of the planet's best scientists and engineers.
For now, we are petitioning the United Nations and President Obama to mobilize the global scientific and engineering community to take charge at Fukushima and the job of moving these fuel rods to safety.

If you have a better idea, please follow it. But do something and do it now.
The clock is ticking. The hand of global nuclear disaster is painfully close to midnight.
