Fukushima Underground Zeolite Wall Explained

Fukushima Underground Zeolite Wall Explained

TEPCO and the team of contractors that worked on the underground zeolite wall have released more detail about the validation process for the project. A pairing of materials was used in the underground bundles installed downstream from the leaking water tanks. Apatite and clinoptilolite ( a type of zeolite) were combined along with some crushed rock to achieve what they think will be a better filtration of the strontium 90 in the ground water. Clinoptilolite was used … Read entire article »

Fukushima Worker Electrocuted, 3 Power Issues At Plant

An electrician was electrocuted while working on the new office building at Fukushima Daiichi. The worker was taken to the Iwaki hospital and is expected to be there for a number of days. Two apparently unrelated power issues also happened at the plant the same day. A low voltage alarm went off repeatedly in the common pool building. No reason could be found so workers reset the system. The RHR cooling system for unit 5 was also shut off while workers inspected a power panel and replaced some equipment. No abnormalities were documented in either case. http://www.tepco.co.jp/nu/fukushima-np/handouts/2014/images/handouts_140930_05-j.pdf This article would not be possible without the extensive efforts of the SimplyInfo research team Join the conversation at chat.simplyinfo.org All content is copyright SimplyInfo.org.

Japan Doubles Hospitals Labeled As Radiation Response In Name Only

Japan Doubles Hospitals Labeled As Radiation Response In Name Only

We reported last week on the response failure of radiation injury capable hospitals during the Fukushima nuclear disaster. The government has announced that the number of hospitals designated as radiation response hospitals has about doubled. Kyodo News discovered that these newly designated hospitals lack the needed human resources and equipment to actually operate at radiation response hospitals. This of course sets up a disastrous problem if these hospitals are called to respond to a radiation emergency … Read entire article »

Researchers Find Radiation Hot Spots Off Coast Near Fukushima

Researchers Find Radiation Hot Spots Off Coast Near Fukushima

Japan’s nuclear regulator and a team of researchers completed a set of sea floor monitoring earlier this summer. They found that areas of the sea floor where there is more muddy soil in low spots tended to concentrate cesium 137. The cesium is assumed to have bonded to the mud particles. The research corridor was roughly up to 25km out to sea. Average cesium 137 concentrations in the sea floor were 90 bq/kg Areas 4 km out to … 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 All content is copyright SimplyInfo.org.

Fukushima Unit 3 Dust Disperal Hints At Accident Events

TEPCO’s report on contaminated dust dispersal that ended up contaminating rice fields north of the damaged nuclear site may indicate more about the accident events. The dates where they were removing the sections of the crane and underlying debris from directly over the reactor well coincide with the contamination dates. TEPCO additionally cited that those days lacked rain that otherwise could have helped keep dust from flying away in the wind. The events combined with … Read entire article »

Japan’s Old Nuclear Program Is New Again

Japan’s Old Nuclear Program Is New Again

Nuclear restarts in Japan have taken a political turn. Japan’s industry minister revived previous administration’s claims that Japan “needs” nuclear power, citing claims of energy independence. Japan has no domestic uranium resources so even their nuclear program is dependent on importing nuclear fuel materials. The country has long tried to make a fuel reprocessing program work but has run into the reality of costs and viability. The minister also brought back the nuclear safety myth, … Read entire article »

Groundwater Bypass May Be Lowering Contaminated Water At Fukushima Daiichi

Groundwater Bypass May Be Lowering Contaminated Water At Fukushima Daiichi

TEPCO thinks the groundwater bypass system they are operating at Fukushima Daiichi may be reducing the contaminated water outflow by up to 80 tons of water per day. This is based on a mathematical calculation of water readings and rainfall. TEPCO also reported that groundwater levels had dropped by about 20 centimeters. It may be too early to completely declare the project a success. A clearer understanding of any change made by the bypass should … Read entire article »

New Fukushima Evacuation Revelations From First Responders

This information was found buried in a HiCare conference report from later in 2011. They explained their response as radiation health professionals along with what they saw and learned during the Fukushima Daiichi evacuations. Japan developed a radiation emergency response system after the Tokai criticality incident in 1999. This system set up hospitals that could treat those with radiation exposure and related injuries. This system did not take into account a natural disaster involved with a nuclear incident or one of the compounded challenges that happened with the Fukushima disaster. There are a total of 92 hospitals around Japan involved in this response system. The number of these hospitals prepared to handle more challenging radiation exposure cases is a considerably smaller number. There are two facilities in Japan capable of handling … Read entire article »

Fukushima Workers File Suit Over Missing Pay

Workers have taken the unusual step of suing TEPCO for unpaid wages, even though the four workers are employed by TEPCO contractors. The issue surrounds danger pay that is supposed to be issued to all workers at the plant including contract workers.

TEPCO Drops Bombshell About Sea Releases; 8 Billion Bq Per Day

TEPCO made the startling admission today at a press conference that the plant is leaking 8 billion bequerels per day. (8 gigabequerels) 5 billion bq of strontium 90 2 billion bq of cesium 137 1 billion bq of tritium * (later corrected to 150) This is the ongoing daily release to the Pacific. These release numbers are also within the realm of what some oceanographers have been warning about since last year, that there was an ongoing and considerable leak to the sea. According to journalist Ryuichi Kino TEPCO said this may be due to failings of some sort within the “glass” wall at the sea front. This is an underground wall made in the soil by injecting a solidifying agent to block water flow. This daily release would add up to 11,680,000,000,000 = 11 terabequerels … Read entire article »
