U.S. and Japanese troops cooperate on rescue effort

Tweet

Reports  from multiple sources indicate that United States military personnel are aiding Japanese military and civilian personnel in search-and-rescue efforts:

Thousands of Japanese and American military personnel joined together Friday in a final three-day sweep to search for those still missing from last month’s massive earthquake and tsunami.

The operation involves 120 aircraft and 65 ships and will cover the three prefectures hit hardest by the March 11 disaster.  More than 11,000 people are confirmed dead, with more than 16,500 still missing. But the search teams will stay out of a 30-kilometer zone around the radiation-leaking Fukushima nuclear plant.

Workers have been struggling since the quake to bring the damaged plant under control. Chief government spokesman Yukio Edano said Friday that current circumstances meant that it would be a “reasonably long” period of time before those evacuated from the nuclear-threat zone would be allowed back to their homes.

A generation or two ago – depending on how one counts, we were engaged in mortal combat with the Japanese.  About one generation back, we sold them most of the nuclear reactors which recently ran aground. (We’ve got a bunch of the same reactors in operation in the United States, sold to the Japanese at a time when nuclear power’s risks were less apparent to the people of both countries). We do better, and will in future do better, as allies than as enemies. As sad, and frightening as events in Japan have been, we think it right and fitting that U.S. troops are assisting the Japanese. We wish them all good luck and freedom from mishap in these efforts, which are not without risk.

 

Fukushima: GE Mark 1: Unsustainable by Design

In Sustainability by Design, John Ehrenfeld defines sustainable design as “That which allows for and even stimulates flourishing forever. ” Nuclear plants are, according to Ehrenfeld’s definition, Unsustainable by design!”

Washington, 1972: “If the cooling systems fails at a ‘Mark 1’ nuclear reactor, the primary containment vessel surrounding the reactor will probably burst as the fuel rods inside overheat. Dangerous radiation will spew into the environment.” – Stephen Hanauer, U.S. Atomic Energy Commission, Safety.

The core in “Pressurized Water Reactors is sealed inside a thick steel-and-cement sarcophagus, similar to what is now being built around Chernobyl. This suggests what we must eventually do to remediate the area on which now stand the Japanese reactors at Fukushima Dai-ichi, Diani, and Onagawa – entomb the entire plants in artificial mountains of cement and steel.

However, the containment vessel and pressure suppression system used in  Japan’s Fukushima Daiichi facility is physically less robust. It has been understood to be more susceptible to failure in an emergency than other, more expensive designs. Safety costs money.

In the United States, 23 reactors at 16 locations use the Mark 1 design, including Oyster Creek, Vermont Yankee, Browns Ferry, Alabama, Fermi, Illinois.
