Fukushima: pressure of groundwater causing underground wall around reactors to lean and crack

safety-symbol-SmTV: Underground wall around Fukushima reactors started “leaning” — Cracks developing due to rising water levels — Problems seen along almost entire length of sea wall — Trying to make repairs to keep groundwater from surging (VIDEO) http://enenews.com/nhk-underground-wall-around-fukushima-reactors-started-lean-rising-water-levels-causing-cracks-develop-problems-occuring-along-almost-entire-length-sea-wall-tepco-trying-make-repairs-keep-gro?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29

NHK World, Nov 25, 2015 (emphasis added): Groundwater wall at Fukushima plant leans slightly — The operator of the damaged Fukushima Daiichi nuclear plant has found that a wall it built 30 meters into the ground to block the flow of radioactive water is leaning slightly. {TEPCO] built the steel barrier along a coastal embankment to stop contaminated groundwater from seeping into the sea… TEPCO inspectors found that the wall is leaning up to some 20 centimeters toward the sea. They say this is due to the pressure of the groundwater flow. The officials also blamed rising groundwater levels for cracks found in the embankment’s pavement. The utility says workers are buttressing the wall with steel pillars…

NHK (Google translation), Nov 25, 2015: In TEPCO Fukushima Daiichi nuclear power plant, it can be seen that the equipment called “impervious wall”, which was completed last month in order to reduce the outflow of the contaminated groundwater, are slightly tilted to the sea side… [T]he pavement of the seawall also cracked… When depends on the Tokyo Electric Power Company, after the “impervious wall” has been completed, it is that it’s because thewater level of the land side of the groundwater is rising.

Fukushima Minyu Shimbun (Google translation), Nov 26, 2015: …  sea side wall is inclined about 20 centimeters at the maximum to the sea side, cracks of up to about 1 centimeter has occurred in the pavement of the seawall. That inclination and cracks have occurred in almost the entire sea side wall… TEPCO, rain water enters the cracks of the pavement, so that the groundwater does not surge, is promoting the repair to block the cracks spraying resin.
