let's face it this disaster ( which was totally preventable )
Earthquakes are preventable? Please show us how. You stand to make substantial amounts of money with your earthquake prevention scientific know-how.

Which is exactly why Japan shouldn't have any nuclear plants period. Mankind has been trying to beat Mother Nature for centuries... she will win everytime.
3 radiation monitors down for 3 days in the pool to accept fuel assemblies from reactor4 SFP
3 radiation monitors were down for 3 days in common usage pool.
This pool is to stock the fuel assemblies removed from reactor4 spent fuel pool.
The monitors are to measure the atmospheric dose one a day. They didn’t measure from 4/19 to 4/21.
Tepco didn’t notice it until 13:45 of 4/22/2014.
They measured the radiation level manually, and stated the atmospheric dose didn’t significantly change from 4/18/2014.
There are two power systems in the pool. One of systems was under maintenance on 4/18 according to Tepco. However, it is not known why the other system was suspended together.
F. Daiichi’s site manager Akira Ono says they have kept leaks from reaching the sea. He said, “The ultimate purpose is to prevent contaminated water from going out to the ocean, and in this regard, I believe it is under control.” However, he admitted that they have yet to gain full control of the wastewater storage and treatment situation, “It’s embarrassing to admit, but there are certain parts of the site where we don’t have full control.” Ono says the publicized leaks are probably due to the haste with which many of the storage tanks and pumping systems were built, “We were pressed to build tanks in a rush and may have not paid enough attention to quality. We need to improve quality from here. We need to improve the quality of the tanks and other facilities so that they can survive for the next 30 to 40 years of our decommission period.” Ono also said that the ALPS isotopic removal system might not be able to purify all wastewaters by the March 2015 goal. www.japantimes.co.jp...
A new robot for Fukushima accident recovery has been built. The robot, named "Sakuraichigo", was developed by a group including Nichinan (an appliance prototype company) and Chiba Institute. Sakuraichigo is an upgraded version of the “Quince” machine used since 2011. It is more compact to maneuver in tight areas, but can be unfolded into a larger unit as needed. It has four cameras as well as temperature and radiation monitoring equipment. Sakuraichigo is waterproof so it can function in radioactive liquid. It can be run wirelessly for up to eight hours and can easily climb stairs at a 45o angle. The robot was demonstrated in Tokyo on April 18 and will soon be used at F. Daiichi. mainichi.jp...
They've Found the Missing Fukushima Nuclear Cores ... Scattered All Over Japan
We reported in May 2011 that authorities knew – within days or weeks – that all 3 active Fukushima nuclear reactors had melted down, but covered up that fact for months.
The next month, we reported that Fukushima’s reactors had actually suffered something much worse: nuclear melt-throughs, where the nuclear fuel melted through the containment vessels and into the ground. At the time, this was described as:
The worst possibility in a nuclear accident.
But now, it turns out that some of the Fukushima reactors have suffered even a more extreme type of damage: melt-OUTS.
By way of background, we’ve noted periodically that scientists have no idea where the cores of the nuclear reactors are.
And that highly radioactive black “dirt” has been found all over Japan.
