That is why they really need to go through some Potential Problem Analysis with different senarios. The nuclear reactor seemed to survive the tsunami, but the backup generators were lost because of the wave. They need to to some theorectical work on if they generators stayed on line (higher ground) would there have been some other difficulty that would have cause problems with the water cooling systems (like debris in the line, plugged filters or other electrical failure because of outside water). Additionally, I know were I am at they have done some tsunami modeling based on the shape of the ocean floor. Not all areas will need that high of protection as the ocean floor would not create one that high...it will be custom to each area.
While it is a bad situation to have 3 complete meltdowns, the radiation release was fare less then Chernobyl's one meltdown due to design. However, the still continued use of fresh water to cool the reactors and leakage of it into the ground water as well as sea water is concerning should it continue. I know the TEPCO Roadmap is supposed to have this fixed very soon and am anxious to see if they achieve it.
IAEA to end meeting on nuclear safety without agreeing new rules
Local Japanese News In English
The United Nations atomic agency may miss a chance to strengthen international nuclear safety today when delegates conclude a meeting on Japan's Fukushima Dai-Ichi reactor meltdowns without implementing new policies.
The International Atomic Energy Agency's 151-nation ministerial meeting ends today in Vienna with countries set to delay future negotiations until September, when the IAEA holds its annual general conference alongside a separate high-level UN summit called by Secretary General Ban Ki-Moon. (UPI)

Radioactive hotspots found in prefectures neighboring Tokyo
Local Japanese News In English
Radioactive hotspots have been found in prefectures neighboring Tokyo with levels of cesium rivaling those found in the least contaminated parts of Fukushima prefecture, according to the Ministry of Education, Culture, Sports, Science and Technology (MEXT).
MEXT released radiation maps of Chiba and Saitama prefectures, both of which neighbor Tokyo, as part of its plan to draw up a visual guide to radiation levels across all of eastern Japan in the wake of the Fukushima Daiichi nuclear crisis.
In a region covering about 10,000 square hectares (38 square miles) of Chiba prefecture and including cities such as Kashiwa and Abiko, levels of cesium 134 and 137 were found in the 60,000 to 100,000 becquerel range - about the same as the least contaminated parts of Fukushima prefecture. Cesium 134 and 137 are by-products of the radiation the core of a nuclear reactor produces. (majirox news)

A 5.9 earthquake just hit Japan again and this time it was close to this plant. I hope there is not another repeat of this disaster.
Bird life badly hit by nuclear fallout in Japan
Local Japanese News In English
Researchers working in the irradiated zone around the disabled Fukushima nuclear plant say bird populations there have begun to dwindle, in what may be a chilling harbinger of the impact of radioactive fallout on local life.
In the first major study on the impact of the world's worst nuclear crisis in 25 years, the researchers from Japan, the US and Denmark say that analysis of 14 species of birds common to Fukushima and Chernobyl shows the effect on numbers is worse in the Japanese disaster zone.
Published next week in the journal Environmental Pollution, the paper says its findings demonstrate "an immediate negative consequence of radiation for birds during the main breeding season March-July".
Two of the study's authors have spent years working in the irradiated 2,850sq m zone around the Chernobyl plant, which exploded in 1986. A quarter of a century later, the zone is almost devoid of people.

Japan marks 1 year since quake, tsunami disaster
RIKUZENTAKATA, Japan - Through silence and prayers, people across Japan on Sunday remembered the massive earthquake and tsunami that struck the nation one year ago, killing just over 19,000 people and unleashing the world's worst nuclear crisis in a quarter century. Ref. Source 8
Very high radiation, little water in Japan reactor
One of Japan's crippled nuclear reactors still has fatally high radiation levels and hardly any water to cool it, according to an internal examination that renews doubts about the plant's stability. Ref. Source 1
Japan is Poisoning Other Countries By Burning Highly-Radioactive Debris
Gundersen says that radioactivity from the burnt debris will end up not only in neighboring prefectures, but in Hawaii, British Columbia, Oregon, Washington and California. Ref. Source 1
