ITER

A Star in a Bottle. "An audacious plan to create a new energy source could save the planet from catastrophe. But time is running out."

Ever wonder what happened to Fukushima Storage Unit #4?

Ever wonder what happened to Fukushima Storage Unit #4? You remember, the one filled with 1,500 wet stored and combustible fuel rods that threaten a total of ~134 million curies of radioactive cesium137 and, at least as of last April, seemed to be in maybe not such great shape? (PREVIOUSLY) This August, TEPCO released a comprehensive and easily understandable report on the condition of the structure as well as measures being done to both reinforce it against likely earthquakes and ultimately remove the fuel rods, which are still hot enough to require wet storage elsewhere (PDF). On the other hand, Kohei Murata, the former Japanese Ambassador to Switzerland who had the attention of the world during the crisis, remains both unimpressed and eschatological.

The (nuclear) path not taken

Nuclear engineers are never taught about the other kind of nuclear reaction. But a working prototype was built over 40 years ago. "The thick hardbound volume was sitting on a shelf in a colleague’s office when Kirk Sorensen spotted it. A rookie NASA engineer at the Marshall Space Flight Center, Sorensen was researching nuclear-powered propulsion, and the book’s title — Fluid Fuel Reactors — jumped out at him. He picked it up and thumbed through it. Hours later, he was still reading, enchanted by the ideas but struggling with the arcane writing. “I took it home that night, but I didn’t understand all the nuclear terminology,” Sorensen says. He pored over it in the coming months, ultimately deciding that he held in his hands the key to the world’s energy future." [more inside]

Tamahagane steel is bliss

Samurai-Sword Maker's Reactor Monopoly May Cool Nuclear Revival There stands the only plant in the world...capable of producing the central part of a nuclear reactor's containment vessel in a single piece, reducing the risk of a radiation leak. From a windswept corner of Hokkaido, Japan's northernmost island, Japan Steel Works Ltd. controls the fate of the global nuclear-energy renaissance. Each year the Tokyo-based company can turn out just four of the steel forgings that contain the radioactivity in a nuclear reactor. Even after it doubles capacity in the next two years, there won't be enough production to meet building plans. [more inside]

"Sending this message was important to us. We considered ourselves to be a powerful culture.

"Sending this message was important to us. We considered ourselves to be a powerful culture. This place is not a place of honor ... no highly esteemed deed is commemorated here ... nothing valued is here. What is here is dangerous and repulsive to us. The danger is still present, in your time, as it was in ours. The danger is to the body, and it can kill." How do we mark our radioactive waste so the warning will be clearly understood for 10,000 years?
