Fukushima Daiichi Unit 3 Fuel Removal To Start Within Year

Fukushima Daiichi Unit 3 Fuel Removal To Start Within Year

TEPCO told Yomiuri Shimbun that they expect to begin removing spent fuel at the unit 3 reactor within the 2015 fiscal year. Work to remove the damaged fuel handling crane has been delayed until April due to the complexity of the task. TEPCO will need to install a cover building vaguely similar to the one installed on unit 4. The building for unit 3 will have to work around existing structural and technical challenges unique to … Read entire article »

Oil Leak In Fukushima Daiichi Unit 3 Spent Fuel Pool

Oil Leak In Fukushima Daiichi Unit 3 Spent Fuel Pool

An oil leak occurred in the spent fuel pool of unit 3 at Fukushima Daiichi today as work was under way to remove parts of the fuel handling machine. The fuel crane fell into the spent fuel pool during the massive explosion at unit 3. TEPCO has been taking the crane out in sections. Oil from the crane leaked into the pool as a section was removed. The cooling loop for the spent fuel pool … Read entire article »

TEPCO Under Fire For Leaks At Fukushima Daiichi

TEPCO Under Fire For Leaks At Fukushima Daiichi

TEPCO has again been receiving growing criticism over their handling of contaminated water at the plant. The first leak, from a series of drainage canals that route from up on the hill where the tank farms reside down to the port has been under increased scrutiny by Japan’s NRA. It appears that heightened oversight of this first leak may have led to the admission of the second leak where contaminated water from unit 2′s roofs was … Read entire article »

2nd Mobile Strontium 90 Filter System In Service At Fukushima Daiichi

2nd Mobile Strontium 90 Filter System In Service At Fukushima Daiichi

A second mobile strontium 90 filtration system is in service at Fukushima Daiichi after initial testing. The portable system housed in modified shipping containers are being used to filter out strontium 90 from contaminated water sitting in tanks. The systems can remove most of the strontium 90 from the contaminated water. This considerably reduces this type of contamination and further reduces some of the risk factors involving the massive tank farms on site. TEPCO has not … Read entire article »

TEPCO Says Safety Upgraded At Fukushima Plants After Two Deaths

TEPCO Says Safety Upgraded At Fukushima Plants After Two Deaths

TEPCO says they responded to the deaths of two workers by stopping work and reviewing safety at the plants. This was TEPCO’s response: TEPCO’s response is obviously superficial. It seems to lack any serious analysis of the work processes and management at the plant that are the root cause of the many accidents that have injured or killed workers in the last year. The responses themselves are all quite temporary in nature. It was also reported … Read entire article »

Fukushima Daiichi Seafront Well Radiation Skyrockets

Fukushima Daiichi Seafront Well Radiation Skyrockets

Well number 1-12 experienced an over 50 times increase in radiation this week. The well sits between the unit 1 and unit 2 intakes. This reading is the highest to date for this well. It is currently unclear exactly what is causing the increase since no nearby wells increased before or in conjunction with this one. There are three possible reasons for this well to increase: 1.

Fukushima Daiichi Updates From IRID Part 3; Testing The Goo

IRID has made some progress on their research to find ways to seal the containment structures at Fukushima Daiichi. The plan has been to flood the containment structures in order to provide shielding during the fuel removal procedures. Concern has been raised about the ability of these structures to hold the weight and pressure of that much water or how this would impact the structure during an earthquake. The structures are already severely damaged along … Read entire article »

How Fukushima Daiichi Could End Up Fueling Cars In Japan

One of the funded research projects towards the response to the Fukushima nuclear disaster may have an unusual side effect if the project eventually goes into operation. The Kurion tritium removal system being developed for use at Fukushima Daiichi could provide hydrogen fuel for cars in Japan. If this technology works as claimed and can be put into operation two of the byproducts would be hydrogen gas and pure oxygen. These byproducts could be captured for … Read entire article »

What May Be Causing The New Reactor Building Leak At Fukushima Daiichi

What May Be Causing The New Reactor Building Leak At Fukushima Daiichi

TEPCO admitted last week that some subdrain pit wells at the Fukushima Daiichi plant showed a large increase in contamination. These wells were originally a system used to remove groundwater from the reactor building basements, similar to a sump pump system. After the disaster these wells were largely ignored until this year. TEPCO began sampling them and later came up with this idea to pump water out of the subdrain pits, decontaminate it and dump … Read entire article »

Two Quakes Hit Offshore Of Fukushima Daiichi

Two moderate quakes hit offshore of Fukushima Daiichi today. “The Japan Meteorological Agency says the first earthquake struck at 9:45 p.m. JST (8:45 a.m. EDT in the U.S.) and registered a magnitude of 5.0. The second quake, a slightly stronger magnitude-5.2 tremor, struck 46 minutes later.” The quakes were about 50km deep, no tsunami alerts issued. Both monitoring cameras at the plant didn’t show any obvious signs of anything changed. No clear reports of conditions at the plant have been released by TEPCO. The quake strength isn’t unusual, the close time frame is.   http://www.weather.com/news/fukushima-two-earthquakes-one-hour-20140924 http://www.globalpost.com/dispatch/news/xinhua-news-agency/140924/m50-quake-jolts-fukushima-japan   This article would not be possible without the extensive efforts of the SimplyInfo research team Join the conversation at chat.simplyinfo.org © 2011-2015 SimplyInfo.org, Fukuleaks.org All Rights Reserved Content cited, quoted etc. from other sources is under the respective rights of that content owner.
