w*p 发帖数: 16484 | 1 New tests show almost all of the fuel inside one of the Fukushima plant's
reactors has melted, its operator said Thursday, the latest step in the
clean up after Japan's worst ever nuclear crisis.
Tokyo Electric Power Co. said the technology, which uses elementary
particles called "muon" to create x-ray style images, gave the most concrete
evidence yet the fuel had dropped to the bottom of the first reactor.
The data, though largely expected, should help TEPCO as it continues its
effort to decommission the plant four years after an earthquake and tsunami
caused one of the worst nuclear meltdowns in living memory.
Engineers have not been able to develop a machine to directly see the exact
location of the molten fuel, hampered by extremely high levels of radiation
in and around the reactors.
"While our previous analysis have already strongly suggested that fuel rods
had melted down, the latest study provided further data that we like to
regard as a progress in our effort to determine the exact locations of the
debris," said a TEPCO spokesman.
TEPCO plans to eventually use robots to locate the fuel debris as part of
the decommissioning process, which is expected to take three to four decades
to complete.
Last month the International Atomic Energy Agency said Japan had made "
significant progress" in its cleanup efforts but warned the situation "
remains very complex" due to the growing amounts of contaminated water
generated by the process.
The Fukushima Daiichi nuclear plant was directly hit by the 9.0-magnitude
earthquake and killer tsunami of March 2011.
It lost emergency power to cool the reactors, which went into meltdown,
contaminating a vast region in northern Japan. |

石燃料的,绿色和平经常炸油轮,但是一般不炸核电站

只不过油轮无防卫好靠近,核电站就那么几个,个个戒备森严,绿色和平组织还不想被
爆头

R***a 发帖数: 41892 | 9 所以左B还是反核电啊。除去极端左B,左翼是反对化石燃料,反对生物燃料,
反对核燃料的。左翼不反的是太阳能风能潮汐能地热能。左翼原则不反水电,但是恐怕
会反建水坝。
