They can't yet. It takes years for the rods to cool enough to be able to safely take them out and put then into a permanent storage cask and move them somewhere. The rods that are in pool 4 haven't quite gotten to that point yet, so they have to stay there a little while longer until they can be safely moved.


How much more time is "a little while longer until they can be safely moved"? 1 year, starting in November, maybe? There are over 1,000 fuel rods in pool #4 if my memory is correct.

But who knows what is really going on, I don't trust TEPCO as an honest source.

Japan's Fukushima nuclear plant making progress on fuel rod removal | CTV News


TEPCO also plans to remove melted fuel from the wrecked reactors within 10 years, but full decommissioning of the plant is expected to take decades.


Another non-mainstream opinion from Robert Alvarez says this:


This then leaves 1,231 irradiated spent fuel rods in pool No. 4, which contain roughly 37 million curies (~1.4E+18 Becquerel) of long-lived radioactivity. The No. 4 pool is about 100 feet above ground, is structurally damaged and is exposed to the open elements. If an earthquake or other event were to cause this pool to drain this could result in a catastrophic radiological fire involving nearly 10 times the amount of Cs-137 released by the Chernobyl accident.

The infrastructure to safely remove this material was destroyed as it was at the other three reactors. Spent reactor fuel cannot be simply lifted into the air by a crane as if it were routine cargo. In order to prevent severe radiation exposures, fires and possible explosions, it must be transferred at all times in water and heavily shielded structures into dry casks.


Edit: I'm not sure how much of an expert Robert Alvarez either.

Either way, this seems to be no easy process, and it will take decades to fully decommission this plant, assuming no more destructive earthquakes damage the plant further. =(

It takes about 10 years after being put into water for them to cool enough to be moved. So 10 years after the first rods were put into the cooling pool they can be moved to a safe storage area, and then the next group, and the next, etc, until they are all moved out of the pool and put into a storage area where they will be safer.

Study: Up to 900 trillion becquerels of strontium-90 into ocean from Fukushima plant — “Direct discharges of cooling water”

Biogeosciences
An Interactive Open Access Journal of the European Geosciences Union


Liquid discharges of 90Sr to the ocean were estimated, resulting in an inventory of 53±1 TBq of 90Sr in the inshore study area in June 2011 and total releases of 90Sr ranging from 90 to 900 TBq, depending upon the reported estimates of 137Cs releases that are considered.

Study: Up to 47 quadrillion becquerels of cesium-137 released into Pacific from Fukushima — Nearly 50 times original Tepco estimate

On 11 March 2011, a Tsunami hit the Fukushima-Daiichi nuclear power plant (FDNPP), which caused the loss of cooling capacity in four of its six nuclear reactors and 25 led to the release a radionuclides into the environment. It is expected that between 6 and 47 PBq (1 PBq= 1015 Bq) of 137Cs (half-live 30.17 yr) was directly discharged into the Pacific Ocean (e.g. Bailly du Bois et al., 2012) in the aftermath of the tragedy. Due to the determined 134Cs : 137Cs ratio of around one, about the same amount of 134Cs (half-live 2.07 yr) was discharged into the Pacific.

Initially, discharge was assumed to represent the larger fraction of total Cs-releases. Therefore, many researchers and TEPCO focussed [sic] on the determination and estimation of the behaviour of Cs in Pacific waters and its behaviour in the environment, especially the uptake by biota (e.g. Buesseler et al., 2011, 2012; Honda et al., 2012; Madigan et al., 2012; Behrens et al., 2012). The explosions of units 1 to 4 of FD-NPP also released radionuclides into the atmosphere which were detectable around the world (e.g. Hsu et al., 2012; Stohl et al., 2012; Jakobs, 2011). From these investigations the wet and dry deposition of caesium isotopes in marine areas where German monitoring was carried out after the accident at FD-NPP occurred, which are the North Sea, the Baltic Sea, and the coastal West and East Greenland currents, were estimated to be between 0.1 and 100 Bqm−2.

Japan Journalist: Situation at Fukushima Daiichi “way worse than officially announced” — Nuclear workers think Fukushima can’t be settled — “They have problems everywhere” (VIDEO)

(From the interview with the workers) The common understanding of Fukushima workers is Fukushima can’t be settled anymore. [...] It’s not only the rat to have caused outage, but they have problems everywhere in the plant. The actual situation is way worse than officially announced


Probably a lot mices, lo0l ..

Thanks for staying on top of this, Maria.
Now, in other news,
"Firm finds there's power in paddles off Outer Banks"

A beach-ravaging winter storm on the Outer Banks could help power homes thanks to a billboard-size fiberglass paddle that generates electricity as it moves to and fro in the sea currents.


Japan needs to give it up and start using other forms of energy.
