By Harvey WassermanRadiation leaks, steam releases, disease and death continue to spew from Fukushima and a disaster which is far from over. Its most profound threat to the global ecology---a spent fuel fire---is still very much with us.The latest steam leak has raised fears around the planet. A worst-case scenario of an on-going out-of-control fission reaction was dismissed by the owners, Tokyo Electric, because they didn’t find xenon in the plume. The company says the steam likely came from rain water being vaporized by residual heat in one of plant’s stricken reactors.But independent experts tend to disbelieve anything Tepco says, for good reason. Reactor Units One, Two and Three have exploded at Fukushima despite decades of official assurances that commercial atomic power plants could not explode at all. The company has been unable to clear out enough radioactive debris to allow it to put a cover over the site that might contain further airborne emissions.Tepco has also been forced to admit that it has been leaking radioactive water into the ocean ever since the disaster began on March 11, 2011. In one instance it admitted to a 90-fold increase of Cesium in a nearby test well over a period of just 3 days.Earlier this year a rat ate through critical electrical cables, shorting out a critical cooling system. When Tepco workers were dispatched to install metal guards to protect the cabling, they managed to short out the system yet again.Early this month Fukushima’s former chief operator, Masao Yoshida, died of esophogeal cancer at the age of 58. Masao became a hero during the worst of the disaster by standing firm at his on-site command post as multiple explosions rocked the reactor complex. Tepco claimed his ensuing cancer and death were “unlikely” to have been caused by Fukushima’s radiation.The impact of work in and near the reactors has become a rising concern. Critics have warned that there are not enough skilled technicians willing to sacrifice themselves at the plant. Tepco has worsened the situation by applying to open a number of its shut reactors elsewhere in Japan, straining its already depleted skilled workforce even further.Meanwhile, a staggering 40% rise in thyroid irregularities among young children in the area has caused a deepening concern about widespread health impacts from Fukushima’s fallout within the general public. Because these numbers have come in just two years after the disaster, the percentage of affected children is expected to continue to rise.And the worst fear of all remains unabated. At Unit Four, which apparently did not actually explode, the building’s structural integrity has been seriously undermined. Debate continues to rage over exactly how this happened.But there’s no doubt that a pool containing many tons of highly radioactive used fuel is suspended 100 feet in the air, with little left to support the structure. Should an earthquake or other trauma knock the pool to the ground, there’s a high likelihood the fuel rods could catch fire.In such an event, the radioactive emissions could be catastrophic. Intensely lethal emissions could spew for a very long time, eventually circling the globe many times, wrecking untold havoc.The Japanese have removed two apparently unused rods from the fuel pool so far. But intense international pressure to clear out the rest of them has thus far been unsuccessful.So while a depleted, discredited and disorganized nuclear utility moves to restart its other reactors, its stricken units at Fukushima continue to hold the rest of us at the brink of apocalyptic terror.
