Fukushima Meltdown
Published 30 March 2011
The radioactive core in the Unit 2 reactor at the Fukushima Daiichi nuclear plant appears to have melted through the bottom of its containment vessel and is now resting on a concrete floor; officials are now struggling with two crucial but contradictory efforts: pumping in water to keep the fuel rods cool and pumping out contaminated water; an investigation found that Tokyo Electric Power Co. officials had dismissed scientific evidence and geological history that indicated that a massive earthquake -- and subsequent tsunami -- was far more likely than they believed; more than 11,000 bodies have been recovered, but officials say the final death toll is expected to exceed 18,000. Hundreds of thousands of people remain homeless, their homes and livelihoods destroyed. Damage could amount to $310 billion -- the most expensive natural disaster on record
Workers at the crippled Fukushima Daiichi nuclear plant appeared to have “lost the race” to save one of the reactors, a U.S. expert told the Guardian.
Richard Lahey, who was head of safety research for boiling water reactors at General Electric when the company installed the units at the Japan plant, says the radioactive core in the Unit 2 reactor appears to have melted through the bottom of its containment vessel and on a concrete floor.
“The indications we have, from the reactor to radiation readings and the materials they are seeing, suggest that the core has melted through the bottom of the pressure vessel in unit two, and at least some of it is down on the floor of the drywell,” Lahey told the paper.
Lahey did add there was no danger of a Chernobyl-style catastrophe.
Japan was hit by another earthquake Wednesday after a magnitude-5.5 earthquake struck off the east coast of Honshu, according to the U.S. Geological Survey.
Fox News reports that Japan’s government vowed Tuesday to overhaul nuclear safety standards once its radiation-leaking reactor complex is under control, admitting that its safeguards were insufficient to protect the plant against the 11 March tsunami.
The struggle to contain radiation at the complex has unfolded with near-constant missteps — including two workers drenched Tuesday with radioactive water despite wearing supposedly waterproof suits. The unfolding drama has drawn increasing criticism of the utility that owns the plant as well as scrutiny of Japan’s preparedness for nuclear crises.
“Our preparedness was not sufficient,” Edano told reporters. “When the current crisis is over, we must examine the accident closely and thoroughly review” safety standards.
An AP investigation found that Tokyo Electric Power Co. officials had dismissed scientific evidence and geological history that indicated that a massive earthquake — and subsequent tsunami — was far more likely than they believed.
That left the complex with nowhere near enough protection against the 11 March tsunami.
A massive offshore earthquake triggered the tsunami that slammed into Japan’s northeast, wiping out towns, killing thousands of people and knocking out power and backup systems at the coastal nuclear power plant.
More than 11,000 bodies have been recovered, but officials say the final death toll is expected to exceed 18,000. Hundreds of thousands of people remain homeless, their homes and livelihoods destroyed. Damage could amount to $310 billion — the most expensive natural disaster on record.
The mission to stabilize the power plant has been fraught with setbacks, as emergency crews have dealt with fires, explosions and radiation scares in the frantic bid to prevent a complete meltdown.
The plant has been leaking radiation that has made its way into vegetables, raw milk and tap water as far away as Tokyo. Residents within twelve miles of the plant have been ordered to leave and some nations have banned the imports of food products from the Fukushima region.
Highly toxic plutonium was the latest contaminant found seeping into the soil outside the plant, TEPCO said Monday.
Safety officials said the amounts did not pose a risk to humans, but the finding supports suspicions that dangerously radioactive water is leaking from damaged nuclear fuel rods.
“The situation is very grave,” Edano told reporters Tuesday.
Fox News reports that workers succeeded last week in reconnecting some parts of the plant to the power grid. As they pumped in water to cool the reactors and nuclear fuel, however, they discovered numerous pools of radioactive water, including in the basements of several buildings and in trenches outside of them.
The contaminated water has been emitting four times as much radiation as the government considers safe for workers. It must be pumped out before electricity can be restored and the regular cooling systems powered up.
That has left officials struggling with two crucial but contradictory efforts: pumping in water to keep the fuel rods cool and pumping out contaminated water.
Officials are hoping tanks at the complex will be able to hold the water, or that new tanks can be trucked in. On Tuesday, officials from the Nuclear Safety Commission, an expert panel of nuclear watchdogs, said other possibilities include digging a storage pit for the contaminated water, recycling it back into the reactors or even pumping it to an offshore tanker.
The latest mishap came Tuesday, when three workers trying to connect a pump outside the Unit 3 reactor were splashed by radioactive water that gushed from a pipe. Though they were wearing suits meant to be waterproof and protect against high levels of radiation, nuclear safety official Hidehiko Nishiyama said the men were soaked to their underwear with the contaminated water.
They quickly washed it off and were not injured, officials said.

Interview with Mexico Drug War expert Sylvia Longmire
Interview with Mexico Drug War expert Sylvia Longmire
Question: First, could you please briefly explain who you are and what you do?
Sylvia Longmire: I’m a former Air Force officer and Special Agent with the Air Force Office of Special Investigations, and also a former senior border security analyst for the State of California. I’m currently a consultant, freelance writer, and author on Mexico’s drug war.
Q: For readers with little or knowledge of what is going on down in Mexico, could you lay out some of the basics of the situation?
SL: Right now, Mexican drug trafficking organizations, or DTOs, are the number one source for illegal drugs consumed by Americans. Because illegal drugs command such high prices on the black market, manufacturing and distributing these drugs to American consumers is a highly profitable business. Currently, there are seven major DTOs in Mexico fighting each other and the Mexican government for control of the drug smuggling routes that DTOs use to move drugs from their source to American consumers across the southwest border. The fighting between DTOs and with Mexican government forces has resulting in escalating violence since President Felipe Calderón took office in 2006. The violence includes beheadings, public hangings of corpses, mutilation and torture, mass killings, grenade attacks, and shootings in public places with high-powered weapons.
right now. Why is it so complex?
SL: The situation in Acapulco is complex because there is more than one DTO fighting for control of that drug smuggling area, and those DTOs are themselves going through organizational changes. One of them, the Cartel Pacifico del Sur, split off from another major DTO, the Sinaloa Federation, a few years ago, and just recently split in half itself. The name is even new, as it used to be known as the Beltrán Leyva Organization, and also goes by two other names – “El H” and “La Empresa.” Keeping track of who’s doing the smuggling and who’s killing whom gets very complicated when so many DTO players are involved in just one corridor.
Q: How much effect do the cartels in Mexico have for us north of the border? How much effect do we have on them?
SL: DTOs operating in Mexico have a huge presence here in the United States, but most of us don’t know it. They’re actually active in more than 270 U.S. cities, and hundreds more small communities and towns. They use local gangs across the country to distribute drugs for them, and Mexican DTOs even grow marijuana in U.S. National Parks and National Forests. As a result of their proximity in Mexico and their infiltration of our communities, they have become America’s biggest supplier of illegal drugs. Because they’re so in tune with our drug market, Mexican DTOs are impacted by – and usually respond well to – changes in consumer demand. Cocaine demand has steadily gone down over the past several years, but demand for high-potency marijuana, heroin, and methamphetamine has gone up. DTOs have made adjustments to their production and cocaine imports from South America to account for these changes.
SL: I think legalization of marijuana would make a financial difference in DTO profits, but would not end the drug war. DTOs are making a lot of money from the production, distribution and sale of other illegal drugs, as well as from kidnapping and extortion operations. They could also ostensibly go into the legal marijuana business, although the profits would be smaller. Just like organized crime groups in the U.S. didn’t go out of business after Prohibition ended, DTOs will still be around if marijuana were ever legalized. As far as legislation and policy goes, I think most of the pro-gun-lobby-backed legislation that limits what the ATF can do needs to be repealed so we can attack the southbound weapons trafficking problem head-on, starting with the Tiahrt Amendment. I think more resources – specifically money and trained people – need to go to border agencies like the Border Patrol, Customs and Border Protection, Immigration and Customs Enforcement, the ATF, etc. But before those resources are distributed, the Department of Homeland Security needs to take a realistic look at what and where the need are. I think DHS management in Washington is too far removed from the border, and doesn’t fully comprehend the challenges along the border and what it takes to meet them head on. I also think both the U.S. and Mexican governments need to stop treating the Mexican DTOs like criminals and start regarding them as hybrid organizations, a cross between organized crime, insurgency, and terrorist groups.
Q: Is there anything specific you think readers need to know regarding the cartels which we have not covered?
SL: Readers need to know that the drug war south of the border affects everyone in the U.S., no matter where we live. DTOs use our highways to transport drugs to every U.S. state. They grow illegal drugs on our taxpayer-funded public lands, and they kidnap and kill people on U.S. soil. Worse yet, they use violent American street gangs to sell illegal drugs to our kids, our brothers and sisters, cousins, parents, coworkers, and friends. All of us have to pay attention to what’s going on if we’re ever going to successfully work with the Mexican government to stop it.
