According to the IAEA team, there have been two big improvements at Fukushima since their last visit.
Firstly nuclear fuel is now being removed from reactor number four - and put in to safe storage. That process is going well.
Secondly the radioactive water at Fukushma is being managed much better than before, and leakage has been reduced.
"The team considers that since our previous mission in April this year, Japan has achieved good progress in improving its strategy and in allocating necessary resources to conduct a safe decommissioning of the Fukushima nuclear power station," team leader Juan Carlos Lentijo said as he delivered the interim report.
On 4 December 2013, the Nuclear Regulation Authority (NRA) of Japan provided the IAEA with an update on radioactivity in seawater at TEPCO's Fukushima Daiichi Nuclear Power Station (NPS).
This update states that the concentrations of Cs-134, Cs-137, total Beta and H-3 were relatively stable from 25 November to 1 December 2013 at the Nuclear Power Station.
In addition, the NRA provided an update on the monitoring report of sea area radioactivity obtained from samples taken in the vicinity of TEPCO's Fukushima Daiichi NPS and in the open sea.

For your better understanding:
Tepco, as well as the J-Government always said it could be
"between 100 and 600 Tones"
but they don't know for sure
because no one is able to say it with 100% Certainty!

The radiation dumped by Fukushima into the environment has exceeded that of the 1986 Chernobyl catastrophe, so we may stop calling it the second worst nuclear power disaster in history. Total atmospheric releases from Fukushima so far are between 5.6 and 8.1 times that of Chernobyl, according to the 2013 World Nuclear Industry Status Report. Prof. Komei Hosokawa, who wrote the Fukushima section, told London’s Channel 4 News, “The situation is not under control. Almost every day new things happen, and there is no sign that they will control the situation in the next few months or years.”
YOTSUKURA, FUKUSHIMA The rising level of tritium measured in kelp samples south of the Fukushima 1 nuclear site is an indicator of intensifying nuclear reactions deep in the soil below the cracked reactors.
The Japan Times July 3 editorial “DPJ ruins chance at power reform” perfectly summarized Japan’s farce of cardboard cut-out clowns masquerading as a political process.

My Trip To The Fukushima Nuclear Disaster Zone (Part One) By Richard Wilcox Ph.D.
Benjamin Fulford: The attack, again, I know you don't necessarily follow this, but the attack to try to loosen it up was the tsunami, and if you, if you go through a newspaper archive, you will find headlines in the New York Times, Los Angeles Times, I have 20 articles and Japanese papers talking about earthquake weapons. And I have DIRECT intelligence from whistleblowers at different levels, were telling me that a, they stole 4 NUCLEAR WEAPONS from the submarine Kursk, OK? (Story of sunken and then recovered submarine Kursk here: en.wikipedia.org... ) (Norwegian scientists and Russia reject rumors there were two nuclear cruise missiles on the Kursk. Story here: www.cnsnews.com... ) That sank off the Baltic, and these aren't under the control of any particular military. They are controlled by rogue intelligence 'actors.' OK? Who are linked to the people, who until now, had the incredibly juicy right of producing dollars and Euros out of thin air. And, they smuggled that WEAPON into a small island off of Okinawa. It was then transported via a fishing boat to Kushin. And then it was taken by car to a property owned by former Prime Minister Nakasone in Suludemuda (sp). Then it was taken to the basement of the North Korean's Citizen Association headquarters in Tokyo. And from there it was transferred onto the deep ocean drilling vessel, the Chikyo Mara. And you won't be able to find newspaper articles in Japanese saying that the Chikyo Mara was drilling a hole right at the epicenter of what became the earthquake, starting January 17th of this year. They drilled down 10 kilometers into the seabed, and they put the (stolen from the Kursk) atomic weapon there. OK? (Apparently, they dropped a nuclear bomb in down a 10" or 12" diameter bore hole pipe...10 kilometers) This was an attempt to pry the Asian money out, through terror. OK? And, we have enough PROOF, the people in the military, the people in intelligence agencies know this. OK? And so, yes, they have been threatening war, they have been threatening nastiness, and right now I am hearing these same rogue actors are planning a nuclear terrorist attack in Europe. OK? There are still three unaccounted for nuclear weapons (from the Kursk)....
At the Democratic Party power broker at Ichiba Ozawa. OK, we have people, we have a list, we have intelligence of people who had inside knowledge previous to this tsunami. We have a conversation between Foreign Minister of the United States, or Secretary of State Kurt Campbell and Ozawa on March 9th, where Campbell told Ozawa we will call off the prosecutors who are harassing you on bogus charges, if you'll agree to keep the current ruling party in power, and we will give you the rights to all the zeolite in Fukushima prefecture.
Zeolite, as you know is used to clean up radioactive waste. This conversation took place on March 9th, 2 days before the tsunami and the attack, and the University of Tokyo detected an anomalous, you know, what is it, radioactive, microwave signals associated with HAARP prior to the tsunami, and they stopped immediately after the tsunami earthquake and out best intelligence tells us this is a deliberate attack involving a seabed, a time bomb and scalar magnetic weapons, OK? And the evidence is there. This is not some way out conspiracy nut. If they want to sue us, we can prove it in court. That's why I guarantee you they won't.
The underground corium pockets can be detected by radiation scanners and with blast tomography, which reveals the locations of larger concentrations. Next, steam-injection pumps used at near-exhausted oil fields should be deployed to pump borax solution into those pockets. Borax unlike boric acid, crystallizes in solution, thereby partitioning the underground spaces with neutron-absorbing barriers. Subdivided into smaller cysts, the fissile materials will be deprived of critical mass.

Wouldn't test drilling be worthwhile? Shouldn't the #1 priority be locating any escaped material?
There was that story about material stopped 30 cm short, but is it confirmed do they know?

In this dataset, the simulation from NOAA's HYSPLIT model shows a continuous release of tracer particles from 12-31 March at a rate of 100 per hour representing the Cesium-137 emitted from Fukushima Daiichi. Each change in particle color represents a decrease in radioactivity by a factor of 10. Radioactivity decreases due to removal by rainfall and gravitational settling. Decay is not a factor for Cesium in this short duration simulation compared to its 30 year long-half life. The air concentration would be computed from the particle density so it is only partially related to the color scale. The released particles are followed through the end of April using meteorological data from the 1-degree resolution NOAA global analyses.

Star for you! Thanks Wishes. We need honesty and integrity, hard to find sometimes.
In Human's little map it looks as if the Pacific Ocean is just a big pretty blue ocean and all is well in la la land. Nothing could be further from the truth. The source material is just another attempt by Tepco and by extension, the Japanese Govt to make everything rosy while the poison the Ocean day after day.
A little honesty would be nice from these cretins but when has that ever happened?

Fukushima — Pacific Ocean radiation levels up 45 million times…
Dewar, the executive director of Physicians for Global Survival, a Canadian anti-nuclear group, says the Canadian government has downplayed the radiation risks from Fukushima and is doing little to monitor them... And evidence has emerged that the impacts of the disaster on the Pacific Ocean are worse than expected.
Since a tsunami and earthquake destroyed the Fukushima Daiichi Nuclear Power Plant last March, radioactive cesium has consistently been found in 60 to 80 per cent of Japanese fishing catches each month tested by Japan’s Fisheries Agency.
In November, 65 per cent of the catches tested positive for cesium (a radioactive material created by nuclear reactors), according to a Gazette analysis of data on the fisheries agency’s website. Cesium is a long-lived radionuclide that persists in the environment and increases the risk of cancer, according to the United States Environmental Protection Agency, which says the most common form of radioactive cesium has a half-life of 30 years.... But the Japanese data shows elevated levels of contamination in several seafood species that Japan has exported to Canada in recent years.
In November, 18 per cent of cod exceeded a new radiation ceiling for food to be implemented in Japan in April – along with 21 per cent of eel, 22 per cent of sole and 33 per cent of seaweed.
Overall, one in five of the 1,100 catches tested in November exceeded the new ceiling of 100 becquerels per kilogram. (Canada’s ceiling for radiation in food is much higher: 1,000 becquerels per kilo.)
“I would probably be hesitant to eat a lot of those fish,” said Nicholas Fisher, a marine sciences professor at the State University of New York at Stony Brook.... In October, a U.S. study – co-authored by oceanographer Ken Buesseler, a senior scientist at the non-profit Woods Hole Oceanographic Institution in Woods Hole, Mass., – reported Fukushima caused history’s biggest-ever release of radiation into the ocean – 10 to 100 times more than the 1986 Chernobyl nuclear catastrophe...
“The reassurances have been completely irresponsible. To say there are no health concerns flies in the face of all scientific evidence,” said Edwards, who has advised the federal auditor-general’s office and Ontario government on nuclear-power issues.
The Gazette analyzed the Japanese fisheries data for 22 seafood species that Japan has exported to Canada in recent years.
Some cesium was found in 16 of these 22 species in November, the last full month for which data was available.
Cesium was especially prevalent in certain of the species:
73 per cent of mackerel tested
91 per cent of the halibut
92 per cent of the sardines
93 per cent of the tuna and eel
94 per cent of the cod and anchovies
100 per cent of the carp, seaweed, shark and monkfish
Some of the fish were caught in Japanese coastal waters. Other catches were made hundreds of kilometres away in the open ocean... CFIA now relies on Japanese authorities to screen Japanese food exported to Canada.
But Japan’s monitoring of food has come under a storm of criticism from the Japanese public after food contaminated with radiation was sold to consumers.
A Canadian seafood industry official was surprised when told CFIA doesn’t plan any more tests of Pacific fish... One of those studies found that fish and crustaceans caught in the vicinity of Fukushima in late March had 10,000 times more than so-called safe levels of radiation. The study, published last May in the journal Environmental Science & Technology, also said macroalgae had 19,000 times the safe level.
Those levels were measured before the Japanese utility that runs the crippled nuclear plant dumped 11,000 tonnes of radioactive water into the Pacific in April and additional leaks that have released hundreds of tonnes more.
But since that early study, little research has been published on the topic.
“People want to know what’s happening with the cesium and how much is in the fish, but we don’t know. It’s frustrating,” said oceanographer Buesseler.
“It’s disconcerting how big of an event Fukushima was and how little data are out there. No one has taken responsibility for studying this in a single agency (in the U.S.), even though we also have reactors on the coast and other events could happen,” he said.
Radioactivity in the Ocean:
Diluted, But Far from Harmless
With contaminated water from Japan’s crippled Fukushima nuclear complex continuing to pour into the Pacific, scientists are concerned about how that radioactivity might affect marine life. Although the ocean’s capacity to dilute radiation is huge, signs are that nuclear isotopes are already moving up the local food chain.
But what impact this radioactive contamination has on marine life and humans is still unclear. Even the mass dumping of nuclear material by the Soviets in the Arctic has not been definitively shown to have caused widespread harm to marine life. That may be because containment vessels around some of the dumped reactors are preventing the escape of radiation. A lack of comprehensive studies by the Russians in the areas where nuclear waste was dumped also has hampered understanding. Two events in the early 1990s — a die-off of seals in the Barents Sea and White Sea from blood cancer, and the deaths of millions of starfish, shellfish, seals and porpoises in the White Sea — have been variously attributed by Russian scientists to pollution or nuclear contamination.
Buessler and other experts say this much is clear: Both short-lived radioactive elements, such as iodine-131, and longer-lived elements — such as cesium-137, with a half-life of 30 years — can be absorbed by phytoplankton, zooplankton, kelp, and other marine life and then be transmitted up the food chain, to fish, marine mammals, and humans. Other radioactive elements — including plutonium, which has been detected outside the Fukushima plant — also pose a threat to marine life.
But that spigot is still running. Since the March 11 earthquake and tsunami, and the resulting damage to the reactors at the Fukushima Daiichi nuclear power plant, huge quantities of water have been poured on four stricken reactors to keep them cool. Thousands of tons of radioactively contaminated water have then been released from the Fukushima complex into the ocean. And even though the Japanese this week stopped a leak of highly radioactive material from the badly damaged Reactor No. 2, the water used to cool the reactor cores continues to flow into the sea. In addition, atmospheric fallout from the damaged reactors is contaminating the ocean as prevailing winds carry radioactivity out over the Pacific.
Approximately 160,000 people evacuated the area around the Fukushima Dai-ichi NPP shortly after it was damage by the earthquake and tsunami. The evacuation order applied to 70,000 of them, while the other 90,000 left voluntarily and returned soon afterward. After more than two years, most of the 70,000 are still not allowed to return to their homes. The 1100 disaster-related deaths caused by the evacuation order show that this pre-cautionary action, taken to minimize cancer risks, was not “conservative.” In this paper, recent studies are reviewed on the consequences of the radioactive releases and on the benefits of many medical treatments with low doses of radiation that were carried out until the 1950s, before the radiation scare was created. Recent research has shed light on the high rate of spontaneous double-strand breaks in DNA and the adaptive protections in cells, tissues and humans that are up-regulated by low radiation. These defences prevent, repair, remove and replace damage, from all causes including external agents. Cancer mortality is reduced. The ICRP’s concept of radiation risk is wrong. It should revert to its 1934 concept, which was a tolerance dose of 0.2 roentgen (r) per day based on more than 35 years of medical experience.
