A pool of three groups, a total of 2500 spent fuel invention is accommodated. Temperature of the pool is about 25 degrees the highest in Unit 4. Also stops cooling, the temperature rise of the current is small, to reach a maximum of 65 degrees of management, that there is a margin of about 4 days. In addition, I have also stopped contaminated water treatment equipment.
At 18:57 of 3/18/2013, Fukushima plant lost the power. In addition to the spent fuel pool of reactor1, 3, and 4, the common pool to stock 6377 also lost the power. The reason is not still identified. According to Japanese meteorological agency, Fukushima plant area is under the storm warnings tonight.
The Japan Times-Mar 13, 2013 Japan urged to send out global SOS over No. ... are calling for a broader range of international experts to be brought on board, including ... still stemming from the spent-fuel pools of the four crippled reactors at Fukushima No.
[... The USS Ronald] Reagan’s crew had been assured that there was no radiation to worry about over the open ocean and, as the ship’s navigator, [Maurice Enis] had been led to believe that the radiation was a distinct plume that they could avoid. It was now apparent that the radiation cloud was everywhere, and avoiding it would not always be possible.
On the quarter mile long deck there was another alarming note. “I had a digital watch,” said quartermaster Jaime Plym, “and it suddenly stopped working.
Somebody made a crack that radiation would do that. There were five or six of us on deck and everyone looked at their watches — and all the digital watches had stopped. There was one that was real expensive, and it wasn’t working either.
“We were laughing at first. But then that petered out and we just sort of looked at each other because it wasn’t funny anymore.” [...]
According to Tepco, the pool water of reactor1 is extremely contaminated compared to other 3 spent fuel pools, which is 5266 times worse than the spent fuel pool of reactor4.
as OF TODAY PEOPLE LIKE I WHO LIVE IN UNITED STATES NEAR THE WATER OF THE PACIFC IS AT RISK OF THIS IM AM NEAR OAKLAND CALIFORINA AND A STORM IS COMING THIS WAY AND ALSO TO ADD TO STROM IS COMING FROM JAPAN ....POPLE MUST TAKE ACTION TO KEEP ONE SELF SAFE BY STAYING IN SIDE OUT OF RAIN AND AFTER SROM ...USE WATER AND SOAP TO TRY TO WASH HOUSE OF CATIMENTS......PS YES I AM HAZEMAT TEAM WORKER AS WELL...PLZ TAKE NOTE OF THIS!!!!!!!!!!!!!!!!!!!!!!!!!
Workers at the tsunami-damaged Fukushima Daiichi nuclear plant in Japan are trying to fix a crucial part of the plant that stopped working today.Currently the cooling systems in [the fuel pools at] reactors one, three and four are not operational and representatives from TEPCO are unsure how to fix them. However TEPCO says it should have a solution within a few days and that the fuel rods stored in the pools will remain safe for at least four days without fresh cooling water
Tepco] said the blackout took place shortly before 7 PM on Monday. [...] They added the blackout has interrupted the cooling system for another pool containing about 6,300 rods. It has also affected part of a system that disposes of contaminated water. [...] The officials will reportedly begin restoring the cooling system once they discover the cause of the interruption.
The risk of [a] tsunami exceeding design basis [was] not considered. Therefore no preparation was made for eventualit[ies] such as “simultaneous and multiple losses of power” and “[station blackout] including DC power supplies.” No operational manuals were in place for recovering instrumentation equipment and power supplies, [primary containment vessel] venting, etc., in such conditions.
TEPCO did not take precautionary measures in anticipation that a severe accident could be caused by a tsunami such as the one [in March 2011]. Neither did the regulatory authorities.
Japan had long tried to establish a permanent storage program for the nation’s spent fuel, to no avail.

The extent of the damage is at least in part due to a lack of preparations in the event of a tsunami. This is a very seismically active area, which begs the question, why build a nuclear power facility with no preventative measures for a potential tsunami when the possibility was inevitable?
The only reason that anything is even close to 'just fine' over there, is because they have been lucky enough so far to not experience another high magnitude quake in close proximity to the site.

Yes, it's still severely damaged, but I don't know anyone that operates nuclear power that has a comprehensive plan to repair a facility that is still operating that has suffered the extent of damage that Fukushima suffered.
