"The deluge would likely cause seawater to mingle with the radiation-tainted water accumulating in the basements of the reactor buildings at the six-unit plant, allowing 100 trillion becquerels of cesium to escape, according to an estimate that Tepco revealed Friday at a meeting of the Nuclear Regulation Authority," the Japan Times reports.
According to the media outlet, tidal waves from the storm are likely to reach a maximum height of 26.3 meters or more. The storm is likely to strike the Fukushima No.2 nuclear plant as well, but "its idled reactors and fuel pools" are not expected to be destroyed, Tepco officials assert.
- It should be noted that the 2011 tsunami reached a height of 15.5 meters when it hit the plant, which was followed by a 9.0 magnitude earthquake.
In order to minimize the impact of the hurricane, Tepco "will reduce the vast quantity of radioactive water" on the site, the Asahi Shimbun notes. Citing Tepco's officials, the media source claims that the amount of contaminated wate, which is expected to spill into the ocean, could be decreased to 30 percent "by filling in trenches near reactors."..................http://en.ria.ru/world/20141004/193667366/Fukushima-To-Be-Hit-By-Typhoon-Causing-Ocean-Contamination-Tepco.html4/10/14
Fukushima No. 1 at risk of 26-meter tsunami: Tepco...
ReplyDeleteTokyo Electric Power Co. has warned its stricken Fukushima No. 1 nuclear plant could be hit by tsunami as high as 26.3 meters.
The deluge would likely cause seawater to mingle with the radiation-tainted water accumulating in the basements of the reactor buildings at the six-unit plant, allowing 100 trillion becquerels of cesium to escape, according to an estimate that Tepco revealed Friday at a meeting of the Nuclear Regulation Authority.
Tepco said a tsunami of that size occurs once every 10,000 to 100,000 years.
The Fukushima No. 1 plant, more than 40 years old, was crippled by the March 2011 earthquake and tsunami after waves as high as 15.5 meters inundated the facility, knocking out all power and disabling the vital backup cooling systems for reactors 1 to 4, triggering three core meltdowns.
Tepco also said the nearby Fukushima No. 2 nuclear plant, which is nearly as old as Fukushima No. 1, could be hit by tsunami of up to 27.5 meters, but that its idled reactors and fuel pools would not be damaged by such an event.

Taifun nimmt Kurs auf Tokio... "Phanfone" fordert Todesopfer ...
ReplyDeleteDer Taifun "Phanfone" ist auf seinem Weg nach Tokio über den Süden Japans hinweggefegt. Dabei kam mindestens ein Mensch ums Leben. Auf der Insel Okinawa, wo US-Soldaten stationiert sind, starb ein amerikanischer Militärangehöriger, wie die Küstenwache mitteilte. Zwei weitere US-Soldaten werden vermisst. Mehrere Menschen wurden zudem auf der etwas weiter nördlich gelegenen Insel Kyushu verletzt.
Regenfluten am Montag erwartet
Am Sonntagabend befand sich der Taifun vor der Küste von Shikoku im Südwesten Japans, seine Winde erreichten nach Angaben des Wetteramtes Geschwindigkeiten von bis zu 144 Kilometern pro Stunde. Der Sturm wird den Meteorologen zufolge am Montagmorgen für rund 40 Zentimeter Niederschlag in Zentraljapan sorgen.
Wegen des Taifuns fielen rund 200 Flüge am Sonntag aus. Weitere 100 für Montag geplante wurden nach Angaben des Senders NHK gestrichen. Heftige Niederschläge behinderten auch das Formel-1-Rennen in Suzuka. Der Große Preis von Japan wurde erst unterbrochen und schließlich abgebrochen, weil die Fahrer nichts mehr sahen und Streckenabschnitte unter Wasser standen. Die Ankunft von "Phanfone" unterbrach zudem den Bergungseinsatz am kürzlich ausgebrochenen Vulkan Ontake.

Tritium up tenfold in Fukushima groundwater after Typhoon Phanfone...
ReplyDeleteThe radioactive water woes at the stricken Fukushima No. 1 nuclear plant got worse over the weekend after the tritium concentration in a groundwater sample surged more than tenfold this month.
A spokesman for Tokyo Electric Power Co. said Saturday that heavy rain caused by Typhoon Phanfone probably affected the groundwater after the storm whipped through Japan last week.
Some 150,000 becquerels of tritium per liter were measured in a groundwater sample taken Thursday from a well east of the No. 2 reactor. The figure is a record for the well and over 10 times the level measured the previous week.
In addition, materials that emit beta rays, such as strontium-90, which causes bone cancer, also shattered records with a reading of 1.2 million becquerels, the utility said of the sample.
The well is close to the plant’s port in the Pacific.
The water crisis could get worse as the nation braces for Typhoon Vongfong this week. Although downgraded from supertyphoon status, the storm was still packing winds of up to 180 kph and on course to hit Kyushu by Monday.
The Meteorological Agency said it could reach Tokyo on Tuesday before gradually losing strength as it races north toward Tohoku.................http://www.japantimes.co.jp/news/2014/10/12/national/tritium-surges-10-fold-in-groundwater-at-fukushima-nuclear-plant-typhoon-effect-suspected/#.VDrrAFfQqt8
