"Apocalyptic" Fukushima Fuel Rod Removal Begins Nov. 8; TEPCO Subcontracts Yakuza gangsters [View all]

I have a bad feeling about this week.


http://www.japantimes.co.jp/news/2013/10/19/national/fukushima-2020-will-japan-be-able-to-keep-the-nuclear-situation-under-control/#.Und0D_ltj_ORemoval of highly radioactive spent fuel from Fukushima Daiichi unit 4, which was rocked by a hydrogen explosion two and a half years ago, will start November 8, according to TEPCO.
]
Unit 4 was down for refueling when the great earthquake and tsunami hit, so the reactor is in good shape, but hydrogen built up around the fuel pool when the power failed leading to a hydrogen explosion on the structure's upper level. TEPCO reinforced the damaged supports for the fuel pool, but its seismic safety remains a major concern. Two new (moderately radioactive) fuel assemblies were successfully removed from the pool in July 2012 by a team of workers (above and below).

Spent fuel must be removed robotically or by operators protected by heavily shielded equipment, unlike the dry run on new fuel, because it is highly radioactive. TEPCO announced that a specialized crane has been installed a week ahead of schedule and fuel removal will begin a week from today.

As long-time anti-nuclear activist Harvey Wasserman explained, the
Spent fuel rods must be kept cool at all times. If exposed to air, their zirconium alloy cladding will ignite, the rods will burn and huge quantities of radiation will be emitted. Should the rods touch each other, or should they crumble into a big enough pile, an explosion is possible.

"In the worst-case scenario," RT adds, the pool could come crashing to the ground, dumping the rods together into a pile that could fission and cause an explosion many times worse than in March 2011. Wasserman says that the plan is so risky it requires a global take-over, an urging Gunter also shared, stating that the "dangerous task should not be left to TEPCO but quickly involve the oversight and management of independent international experts."

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.

Agree, that is the big "unknown" at least given TEPCO track record I would be highly worried about Katashi_itto Nov 2013 #13
