Tepco to Build Wall for Nuclear Plant After Fukushima Disaster  Bloomberg

Tokyo Electric Power Co. will build a seawall to protect its biggest atomic power station from a tsunami like the one that knocked out its Fukushima Dai-Ichi plant, causing the worst nuclear crisis in 25 years.

Japan's biggest power company, known as Tepco, plans to construct a wall to a height of 15 meters (50 feet) above sea level off the coast of its Kashiwazaki Kariwa plant northwest of Tokyo, spokeswoman Ai Tanaka said by phone. Three of seven reactors remain shut at the station after an earthquake in 2007 caused radiation leaks.


Tepco said last week it wants to get approvals to restart the remaining idled reactors at the Kashiwazaki plant, the world's biggest atomic power station, to meet potential shortfalls after losing generating capacity in the disaster.

Tepco has been criticized by the government for responding too slowly to the crisis that unfolded at Fukushima after the tsunami washed ashore. The company also received criticism for the way it responded to the quake that hit near the Kashiwazaki station in 2007. Kashiwazaki should be shut permanently, a group of scientists said one month after the 6.6-magnitude quake hit the area.

Three of seven reactors remain shut at the station after an earthquake in 2007 caused radiation leaks.

Is this not a significant data point in the theory that neither corporations nor governments are capable of managing such potentially destructive technology?

earthquake caused radiation leakage enough to keep 3 of 7 plants shut 4 years. Japan has recorded tsunamis since 1200 or more years to be associated with earthquakes. and a 6.6 quake can hardly be called earth-shaking (a joke only one who's lived in an earthquake zone could make), so they should have been ready for far greater.

Technological hubris allied with the general inability of modern civilization to understand its place in the universe. Administered by brain-dead clones. I wonder what the next excuse will be.

Los alrededores de Chernóbil nunca serán aptos para el ser humano · ELPAÍS.comThe surroundings of Chernobyl will never be fit for human beings - ElPais.com
La energía atómica es peligrosa y su explotación está plagada de incertidumbres, según las intervenciones realizadas este jueves en una conferencia internacional con motivo del 25 aniversario de Chernóbil. No obstante, ninguno de los ponentes en el pleno del evento, celebrado en Kiev, puso en cuestión el futuro de la energía nuclear, pese a las graves secuelas del accidente en aquella central nuclear, el peor en la historia del átomo civil. Superar esas secuelas llevará siglos.Atomic energy is dangerous and its use is full of uncertainties, according to the contributions made this Thursday at an international conference on the 25th anniversary of [the] Chernobyl [accident]. Nevertheless, none of the plenary speakers at the event, held in Kiev, questioned the future of nuclear power, despite the serious after-effects of the accident at that nuclear plant, the worst in the history of civilian [use of the] atom. Overcoming these after-effects will take centuries.

I think the article is a good summary of some of the technical things that were said. I haven't been able to find an equivalent in English...

They do make the helpful observation that over 2000 square kilometers of land could be used for solar power installations, as these require little exposure of humans to the radiation. At 250 watts/m2 that would be 5 gigawatts peak power. This would provide a power stream to replace the power generation lost at Fukushima and produce a revenue stream from the land that could pay for the loss of the use of that land by its current owners. Interspersing solar direct with solar thermal plants would provide the capability for 24 hr. power production from the facility.

This might be the best and highest use of that land for the next few centuries. Better yet, Japan has not yet "forgotten" how to do industrial policy, so they could build the facilities themselves without recourse to world capital markets and all that implies.

La zona de exclusión y la zona de total reasentamiento en torno a Chernóbil "nunca" serán aptas para vivir en ellas, según Mykola Proskura, vicejefe del departamento encargado de administrar los territorios contaminados. Proskura aclaró que el territorio en cuestión tiene un total de 2600 kilómetros y "en el mejor de los casos se podrá reducir a 2000 kilómetros cuadrados, aunque eso será en el futuro lejano". El funcionario precisó que "entre 1500 y 2000 kilometros cuadrados nunca serán aptos para vivir" porque "hay isótopos radiactivos con un periodo de desintegración de 24.000 años y debido al cesio y al estroncio habrá que esperar por lo menos 300 años". La zona puede tener un uso limitado para la economía, opinó, mediante "alguna explotación limpia y que exija poco personal, como la producción de energía eólica". El atlas divulgado se limita al territorio de Ucrania y no da datos ni de Bielorrusia ni de Rusia, los otros Estados que, como parte de la URSS, fueron especialmente afectados por la catástrofe.The exclusion zone and the total resettlement zone around Chernobyl will "never" be fit to live in, according to Mykola Proskura, deputy chief of the department in charge of managing the contaminated territories. Proskura clarified that the land in question has a total of 2600 square kilometres, and "in the best of cases may be reduced to 2000, though that will be in the far future". The civil servant indicated that "between 1500 and 2000 will never be fit to live in" because "there are radioactive isotopes with a [half life] of 24 thousand years and due to Caesium and Strontium we will have to wait at least 300 years". The area may have a limited economic use, in his opinion, by means of "some clean exploitation demanding little personnel, such as wind power". The atlas [of contaminated regions] is limited to the Ukrainian territory and gives no data form Belarus or Russia, the other states which, as part of the USSR, were particularly affected by the catastrophe.

Yeah, but Japan is still in active denial about exclusion zones.

Active and vociferous, it would seem.

Thanks for the translation. I obviously mistook wind for solar -- one word I thought I recognized. :-) I had already looked up three or four words, so you can see why I didn't attempt my own translation.

But the same reasoning should apply to solar installations as to wind. Japan is pushing residential solar with feed in tariffs and installation subsidies, so solar energy farms on otherwise unusable land might be a way to finesse the habitability issue.From the info I dug up quickly on Google it seems the best wind locations are offshore south of Tokyo Bay, and on the north west and north east coast of Honsu. Unfortuantely, the polluted waters off Fukushima are relatively windless.
