Japanese government panel warns on risk that tsunami could overwhelm Fukushima nuclear plant in future Japan earthquake

Tsunami could overwhelm Fukushima nuclear plant in future Japan earthquake, government panel says,  By Travis Fedschun | Fox News 22  Apr 20, Towering waves could overwhelm the wrecked Fukushima nuclear plant in Japan if another mega-earthquake struck the deep-sea trenches off the country’s Pacific coast, a government panel said Tuesday.The Japanese panel said in a report that if an earthquake of magnitude 9.0 or greater struck in the deep-sea trenches, tsunami waves as high as 44 feet could hit the area around the Fukushima plant.

“A massive earthquake of this class (shown in the simulation) would be difficult to deal with by developing hard infrastructure (such as coast levees),” seismologist Kenji Satake, a University of Tokyo professor and head of the panel said Tuesday. “To save people’s lives, the basic policy would be evacuation.”A future mega-quake in the Japan Trench, which extends off Hokkaido, the northernmost of Japan’s main islands, to Boso Peninsula east of Tokyo, or in the Kuril Trench, which goes from Hokkaido to Russia’s Kuri Island, could yield disastrous results.

Waves as high as 98 feet could strike thThe latest government projection suggests a 36-foot seawall planned by the owner of the wrecked nuclear plant, Tokyo Electric Power Co. (TEPCO) would also be overwhelmed if tsunami waves are unleashed, according to Japanese broadcaster NHK. The panel expected waves of at least 44-feet could strike Futaba Town, where the plant is located.
A magnitude 9.0 earthquake that struck off Japan’s east coast in March 2011 spawned a devastating tsunami that struck the nuclear facility. Three reactors at the Fukushima Dai-ichi plant then had meltdowns, causing radioactive water to leak from the reactors and mix with the groundwater and rainwater at the plant. The water is being treated but is still slightly radioactive and is stored in 1,000 large tanks, which hold 1 million tons of water.e northernmost island of Hokkaido, while other tsunamis may strike in areas along the Sea of Japan, according to Kyodo News.

TEPCO currently stores about 1.2 million tons of radioactive water and only has space to hold up to 1.37 million tons, or until the summer of 2022. The water — leakage of contaminated cooling water from damaged reactors mixed with groundwater — has accumulated since the accident. It is constantly pumped up, treated and stored in tanks, while part of it is recycled as coolant.

The company said Wednesday it’s assessing the new government report……..
