#AceWorldNews – JAPAN (Tokyo) – June 23 – Japan’s crippled Fukushima nuclear plant restarted its trouble-plagued water decontamination system for the first time in three months, AFP reported, citing the utility.
Tokyo Electric Power Co (Tepco) has been forced to repeatedly switch off its Advanced Liquid Processing System (ALPS), which attempts to decontaminate radiation-tainted water.
The move followed a series of glitches plaguing the system since trial operations began last year.
Tepco is struggling to handle a growing volume of contaminated water at Fukushima.
#AceWorldNews – TOKYO – May 21 – Workers of Japan’s crippled Fukushima Daiichi (Fukushima 1) nuclear power plant have started dumping ground waters into the Pacific ocean, the NPP operator – Tokyo Electric Power Company (TEPCO) reported on Wednesday.
Representative of the company say the dump will do the environment no harm.
According to a report carried out by EPA: Water Discharges Heavy metals and salts build up in the water used in all power plant systems, including nuclear ones.
These water pollutants, as well as the higher temperature of the water discharged from the power plant, can negatively affect water quality and aquatic life.
Nuclear power plants sometimes discharge small amounts of tritium and other radioactive elements as allowed by their individual waste-water permits.
Waste generated from uranium mining operations and rainwater run off can contaminate groundwater and surface water resources with heavy metals and traces of radioactive uranium.
Accumulation of radioactive ground waters under the NPP is one of the main problems for the clean-up workers at Fukushima.
To pervent it, TEPCO plans by 2015 to create an artificial layer of permanent frost around the power plant and slowly drain the accumulated water.
However, some experts have expressed scepticism regarding the plan.

#AceWorldNews – TOKYO – May 17 – A fault at the stricken Fukushima power plant has caused the facility’s water cleaning system to stop working, said TEPCO, the company that runs the plant.
An accumulation of concentrated calcium in the system’s pipes has blocked the mechanism. TEPCO is currently trying to process hundreds of thousands of tons of radioactive water being used to keep the stricken reactors cool at Fukushima.
#AceWorldNews – TOKYO – March 28 – A worker was unconscious after being buried in a mudslide at Japan’s Fukushima Dai-ichi nuclear plant, officials said.
The man, in his 50s, was rushed to the hospital and his heart stopped beating, AP quoted
Tokyo Electric Power Co. (TEPCO) spokesman Shogo Fukuda as saying.
The worker was digging near storage containers when he was buried Friday.
Thousands of workers have been cleaning up the plant after the disaster three years ago.
#AceWorldNews says hundreds of protestors rallied in Tokyo on Saturday at the decision by Japanese prosecutors to drop charges over the Fukushima nuclear crisis, which some have argued was a “man-made” disaster.
In March 2011 a huge tsunami, triggered by a 9.0 magnitude earthquake, crashed into the Fukushima nuclear plant, causing a meltdown that spewed radiation into the surrounding area, forcing tens of thousands of people to evacuate their homes.
A parliamentary report concluded that Fukushima was caused by Japan’s culture of “reflexive obedience” and not just the tsunami.
Campaigners have said that they will appeal the decision and continue to try and prosecute officials at the plant’s operator TEPCO for their role in the disaster.
#AceWorldNews via NHK World / The operator of the crippled Fukushima Daiichi nuclear plant says water containing extremely high levels of radioactive substances has leaked from a storage tank.
Tokyo Electric Power Company officials said the leak was found on Wednesday night in one of the many tanks being stored on the mountain side of the reactor buildings.
They say the leaked water contained 230-million becquerels per liter of beta-ray emitting substances.
The amount far exceeds government limits.
They say the water leaked from a seam near the top of the tank. It travelled along a rainwater pipe and flowed outside the barrier that surrounds the tank.
Officials say they have taken measures to stop the leakage. TEPCO estimates that about 100 tons of water had leaked.
The utility say the water should not have flowed into the ocean because there are no spillways near the tank that lead to the sea.
Officials say their investigation is still under-way.
#AceNewsServices says `TEPCO Drills freeze wells to stop contaminated groundwater

Tokyo Electric Power Company (TEPCO) pours tons of water into damaged reactors to keep the melted fuel from overheating. But the buildings, which were damaged by the earthquake and tsunami of 2011 and the consequent disaster at the plant, are allowing radioactive material to seep into groundwater and pollute the nearby sea.
In September 2013, the Japanese government announced a plan to drill a row of wells around the area. A liquid coolant running through the wells will cool the soil around them and form a frozen wall in an attempt to prevent contaminated groundwater from getting into the environment.
The work on the wall due to start Wednesday at the Number 2 and Number 3 reactors, Japanese TV station NHK reported.
The program to isolate groundwater is to cost some $320 million in construction plus run costs and is scheduled to be complete by March 2015. The wall, maintained by rows of wells drilled at 1–meter intervals, is to run 500 meters north to south and 200 meters east to west.
The Japanese government chose the approach over more permanent solutions like erecting concrete underground barriers, which do not require a constant operation of freezers and coolant pumps. They said it allows for a quick rebuilding of the wall in case it is damaged by a new quake.
The plan is not guaranteed to work, with some experts fearing the groundwater may end up seeping even deeper once the frozen wall is in place.
The soil-freezing technology has long been used for civil construction in areas of abundant groundwater, for example for building subway lines. But it is usually done temporarily, and there is no record to indicate how reliable the solution would be in the long run.
Fukushima nuclear power plant was crippled in March 2011 by a powerful earthquake and subsequent tsunami, becoming one of worst nuclear disasters in history. TEPCO has been struggling to contain the fallout from the incident, but radiation leakages continue at the facility.
The disaster triggered a massive public outcry against nuclear energy, with several countries going completely rejecting it.

#AceWorldNews says Japan’s Trade Ministry said it would approve a revival plan on Wednesday for the utility responsible for the Fukushima nuclear disaster, Tokyo Electric Power Co, Reuters reported. The plan hinges on TEPCO restarting its Kashiwazaki Kariwa nuclear plant to cut fossil fuel costs. An earlier plan by the company outlining a revival after its Fukushima plant was hit by an earthquake and tsunami in 2011 had to be torn up because it could not restart Kashiwazaki. TEPCO will also cut costs by reducing fuel spending and forming partnerships with other utilities, and upgrade fossil fuel plants.
** NEWS FLASH — URGENT ** STEAM SUDDENLY EMANATING FROM FUKUSHIMA REACTOR # 3 – WEST COAST OF NORTH AMERICA SHOULD BEGIN PREPARATIONS FOR POSSIBLE RADIATION CLOUD WITHIN 3 TO 5 DAYS
I ask you check this link here http://enenews.com/category/japan and this http://enenews.com/ Reactor 3 blew again early Monday morning and was NOT reported by the media, TEPCO should be taken to a field and SHOT for this as should the Japanese Government. Another could has traveled the globe 3 times over already, this one will directly hit the USA and Canada in the coming days and also Australia and parts of Russia and China and that area. This is bad, I am NOT FEAR MONGERING. I SAYING, PREPARE!!! This is HELL. If you can get Potassium Iodide drugs do so. I have sat on this all day today and yesterday and pondered to blog or not. I will. DO NOT EXPECT THIS ON YOUR NEWS, You are on your own. This is killer. I am sorry….
This is also heartbreaking. http://www.reuters.com/article/2013/12/30/us-fukushima-workers-idUSBRE9BT00520131230
NEWS FLASH – URGENT – December 28, 2013 11:00 PM EST — (TRN http://www.TurnerRadioNetwork.com ) — Persons residing on the west coast of North America should IMMEDIATELY begin preparing for another possible onslaught of dangerous atmospheric radiation from the Fukushima nuclear disaster site in Japan. The Tokyo Electric Power Company (TEPCO) says radioactive steam has suddenly begun emanating from previously exploded nuclear reactor building #3 at the Fukuishima disaster site in Japan. TEPCO says they do not know why this is happening and cannot go into the building to see what’s happening due to damage and lethal radiation levels in that building. Experts say this could be the beginning of a “spent fuel pool criticality (meltdown)” involving up to 89 TONS of nuclear fuel burning up into the atmosphere and heading to North America. Steam photo, full details and suggested methods to protect yourself appear below.
The announcements from TEPCO (in Japanese) can be viewed here http://www.tepco.co.jp/nu-news/2013/1233168_5304.html You can use Google Translate to convert to English.
On December 28, 2013, the Tokyo Electric Power Company (TEPCO) admitted steam was seen billowing out of reactor building #3, saying the steam appeared to be coming from what’s left of the fifth floor of the mostly-destroyed building. It is widely known that persons cannot get inside Reactor Building #3 because it is severely damaged and highly radioactive, so TEPCO cannot state for certain what is happening in that building or why. TEPCO admits they do not know why this steam is being generated, but matter-of-factly revealed today (December 28) the steam was first spotted on December 19 for a short period of time, then again on December 24 and again on December 25.
Nuclear energy experts have told TRN that the ONLY way this could be happening is if radioactive material previously ejected from the reactor explosion in March, 2011 has mixed together with other materials and has begun its own self-sustaining reaction(s), also known as a “criticality.” Put simply, another “meltdown” may be taking place.
There are basically two possibilities if another meltdown is in progress:
1) Pellets of radioactive fuel, ejected when the reactor exploded, have mixed together and “mini” meltdowns are taking place with those small clumps of pellets. This would not be a horrific problem and may be manageable, OR;
2) Pellets of radioactive fuel, ejected when the reactor exploded, went into the spent fuel pool located above the reactor and have begun melting down so seriously they are boiling off the water in the spent fuel pool.
Since steam is visible, experts tell TRN that Scenario #2 above is is the most likely scenario and if so, it would be an absolute nightmare — WORSE than the original Fukushima disaster! The Spent Fuel Pool was situated on the fourth floor above Reactor #3, and if this is the source of the steam, the situation could escalate rapidly out of control.
