Plan C Also Failed In Plugging Reactor 2 Trench…Now What?

via EX-SKF.blogspot.com / November 24, 2014 / Plan D of Course! But first, recall that Plan A was to install freezing pipes at the head of the trench leading from Reactor 2 turbine building to create an ice plug so that the extremely contaminated water that had been sitting in the trench since the very beginning of the nuclear accident could be pumped out. TEPCO started the work in April … Continue reading

TEPCO to bury Fukushima plant trench with concrete to control radioactive water

via mainichi.jp / November 23, 2014 / Tokyo Electric Power Co. (TEPCO) has decided to bury a trench at the crippled Fukushima No. 1 Nuclear Power Plant using concrete after an effort to completely stop the flow of radiation contaminated water failed, it has been learned. TEPCO reported its plan to the Nuclear Regulation Authority (NRA) on Nov. 21, and the NRA approved it, saying that the plan can at … Continue reading

TEPCO Fails To Create Ice Wall To Stem Radioactive Water Flow

from the-japan-news.com / August 20, 2014 / Tokyo Electric Power Co. said Tuesday it had failed in an attempt to create an ice wall in an underground tunnel to block the flow of highly radioactive water from a damaged reactor at the Fukushima No. 1 nuclear power station. Since last month, TEPCO has injected more than 400 tons of ice and dry ice to freeze radioactive water in a section … Continue reading

TEPCO Defies Laws Of Physics Claiming Water Freezes At 5 Degrees Celsius

via EX-SKF / July 28, 2014 / TEPCO says by dumping ice and dry ice they can lower the temperature of the contaminated water in the trench to about 5 degrees Celsius, then they will be able to form a continuous ice plug. Here I thought that water freezes at zero degree Celsius. As the whole world is seemingly going crazy afresh this July, maybe TEPCO is correct that water … Continue reading

New Strategy For Fukushima Trench Water

via world-nulear-news.org / July 24, 2014 / New approaches to removing the contaminated water from trenches around units 2 and 3 at the damaged Fukushima Daiichi plant are being explored after attempts to freeze it failed. The trenches contain highly-contaminated water that has flowed from the main power plant buildings – a mixture of injected cooling water and groundwater that has leaked into the basements. In April, Tokyo Electric Power Company (TEPCO) attempted … Continue reading

Fukushima Damage Finally to Be Probed

via guardianlv.com / June 25, 2014 / Three years ago, on March 11, 2011, a catastrophic failure at the Fukushima Daiichi nuclear power plant occurred. Three out of the six nuclear reactors in the plant melted down when the area was hit by a tsunami, which occurred as an after-effect of an earthquake. The 2011 catastrophe was the largest nuclear disaster since Chernobyl in April 1986. It is one of only a … Continue reading

TEPCO fears 3-cm hole in Fukushima reactor No.2

via RT.com / January 30, 2014 / The suppression pool of the Fukushima Daiichi Unit No. 2 reactor may have a 3-centimeter hole in it, through which the highly radioactive water might be leaking out, the plant operator said. The information is based on the data gathered by a robot sent into the suppression pool at the bottom of the No. 2 reactor’s primary containment vessel earlier in January. The … Continue reading

TEPCO: ‘Fracture-like’ Traces Found on Unit 1 and 2 Exhaust Stack

via ENENews.com / Sep 18, 2013 / We have been conducting an on-site inspection for seismic safety evaluation on the exhaust stack for Units 1 and 2 at Fukushima Daiichi NPS. Today (on September 18), in the inspection, we found fracture-like traces on steel members (diagonal bracings) of the exhaust stack (pictured). Since the area around the exhaust stack includes a location with a high dose rate, we will start … Continue reading
