Setbacks at Fukushima: Black Smoke, Evacuations, Dangerous Radioactive Iodine in Tokyo Tap Water

The first photos of the so-called "Fukushima Fifty", the "anonymous band of lower and mid-level managers" (as described by the Daily Mail today in their photo essay) who stayed at the crippled Fukushima Daiichi plant last week, as the rest of the workers were evacuated when radiation had reached record levels there, have now been published by AP.

"Despite sweltering heat from the damaged reactors, they must work in protective bodysuits to protect their skin from the poisonous radioactive particles that fill the air around them," the Daily Mail writes, in its heartbreaking piece, "But as more radiation seeps into the atmosphere minute by minute, they know this job will be their last."

Workers were again evacuated from the Fukushima reactors 3 and 4 late on Thursday (late Wednesday US time), after black smoke once again began to emanate from Unit 3 where a dangerous mix of both uranium and plutonium fuel the reactor, as well as sit in largely unprotected spent fuel ponds in the same damaged building. The roof and walls were blown off of Unit 3 last week after venting of radioactive steam in the reactor led to a hydrogen explosion.

News reports today say that the black smoke, the cause of which is still unknown, has dissipated a bit at Unit 3, and this quick summary of the reactors' status at Fukushima (March 23, 20:00 UTC) from the International Atomic Energy Agency (IAEA) --- which has not always been as up to date as some of the actual news sources on the ground --- suggests workers have now returned to the plant.

"Crews continued today to use a concrete pump truck to deliver high volumes of water into the Unit 4 spent fuel pool, where there are concerns of inadequate water coverage over the fuel assemblies," according to the IAEA.

The biggest news last night was the announcement by the Tokyo Metropolitan Government that radioactive iodine levels in the city's municipal tap water has now increased to levels that are no longer safe for infants. That, according to VOA News' Steve Herman latest report (as well as other sources in Tokyo), has led to a "panic" and a run on bottled water at stores, many of which have now run out entirely.

As Herman reports:

City officials say the affected downtown facility supplies much of the tap water for Japan's capital and five suburban districts. They say the level recorded in the water, drawn from local rivers, is nearly double that considered safe for infants to drink, but still within limits acceptable for adults to ingest.
...
The announcement immediately prompted panic. Citizens began buying huge amounts of bottled water in Tokyo, with some purchasing it by the boxes.

Japan's government quickly asked the public to refrain from excessive purchases of water and said it is looking at ways to provide pure water to families with infants in the Tokyo Metropolitan area.

Beyond that, despite those setbacks at this hour, the status at the Fukushima Daiichi plant seems to be largely in the same place as it was during our previous update yesterday, as lights are slowly coming back on at the various units now that power has been restored to all of them from the grid. But pumping and cooling equipment continues to be malfunctioning in all but the 5 and 6 units at the plant, so work continues to pump water in hopes of keeping down temperatures and radiation at Units 1 to 4.
