Typhoons have damaged Ice Wall at Fukushima Daiichi
Ice Wall at Fukushima Daiichi damaged by recent typhoons in Japan http://enformable.com/2016/09/ice-wall-fukushima-daiichi-damaged-recent-typhoons-japan/?utm_source=twitterfeed&utm_medium=twitter Tokyo Electric Power Company (TEPCO) has announced that the “ice wall” (formally known as the “Land-Side Impermeable Wall”) under construction at the crippled Fukushima Daiichi nuclear power plant in Japan has been critically affected by rainfall from recent typhoons that have melted parts of the ice structure, allowing new pathways for highly contaminated water to leak from the basements of the reactor buildings.
Tokyo Electric will attempt to repair the melted portions of the ice wall by adding additional refrigerant into the underground pipes.
TEPCO has had to repeatedly address issues with the ice wall project, including an announcement in the spring of 2016 that one of the sections had not yet fully frozen.
Experts have warned that the ice wall, being electrically powered, is just as susceptible to damage from natural disasters as the nuclear power plant itself.
“The plan to block groundwater with a frozen wall of earth is failing. They need to come up with another solution, even if they keep going forward with the plant,” said Yoshinori Kitsutaka, a professor of engineering at Tokyo Metropolitan University.
