Just when it couldn't get worse with all the stupid mistakes that have happened so far related to the nuclear plant.
Quotes from the articles:
An operation with potentially "apocalyptic" consequences is expected to begin in a little over two weeks from now - "as early as November 8" - at Fukushima's damaged and sinking Reactor 4, when plant operator TEPCO will attempt to remove over 1300 spent fuel rods holding the radiation equivalent of 14,000 Hiroshima bombs from a spent fuel storage tank perched on the reactor's upper floor.
Fukushima Reactor 4
While the Reactor 4 building itself did not suffer a meltdown, it did suffer a hydrogen explosion, is now tipping and sinking and has zero ability to withstand another seismic event.
Arnie Gundersen, a veteran U.S. nuclear engineer and director of Fairewinds Energy Education, warned this summer that "They are going to have difficulty in removing a significant number of the rods," and said that "To jump to the conclusion that it is going to work just fine is quite a leap of logic."
Gundersen offered this analogy of the challenging process of removing the spent fuel rods:
"If you think of a nuclear fuel rack as a pack of cigarettes, if you pull a cigarette straight up it will come out — but these racks have been distorted. Now when they go to pull the cigarette straight out, it’s going to likely break and release radioactive cesium and other gases, xenon and krypton, into the air.
[...]
"The problem is that this pack of cigarettes is crumpled, and the process must done manually. Therefore, the likelihood that some of the fuel rods will break is high."
The fuel rods must be kept submerged and must not touch each other or break.
“The operation to begin removing fuel from such a severely damaged pool has never been attempted before. The rods are unwieldy and very heavy, each one weighing two-thirds of a ton,” fallout researcher Christina Consolo.
Worst case scenario:
The World Nuclear Report, released in July 2013, said “the worst-case scenario” will require evacuation of up to 10 million people within a 250-kilometer radius of Fukushima, including a significant part of Tokyo.

A "significant milestone" is at hand for cleanup of Japan's Fukushima nuclear plant, with spent nuclear fuel removal likely to start on schedule, the U.S. Energy Secretary said on Friday after a visit to the site.
"It appears that spent nuclear fuel will begin to be removed from Unit 4 as scheduled in mid-November," Ernest Moniz said in a statement. "This will be significant milestone for Tepco and the Japanese government and in the process of decommissioning the site.
