Relocation is not easy, the stress is very big. We must not only track those problems, but also treat them. Otherwise people will feel they are just guinea pigs in our research.
A survey by the Iitate local government obtained responses from approximately 1, evacuees within the evacuation zone. The survey showed that many residents are experiencing growing frustration, instability, and an inability to return to their earlier lives.
Sixty percent of respondents stated that their health and the health of their families had deteriorated after evacuating, while Summarizing all responses to questions related to evacuees' current family status, one-third of all surveyed families live apart from their children, while The survey also showed that A total of Stress often manifests in physical ailments, including behavioral changes such as poor dietary choices, lack of exercise, and sleep deprivation.
Survivors, including some who lost homes, villages, and family members, were found likely to face mental health and physical challenges.
Much of the stress came from lack of information and from relocation. In a risk analysis , relying on the metric of potential months of life lost , it determined that unlike Chernobyl, "relocation was unjustified for the , people relocated after Fukushima", when the potential future deaths from exposure to radiation around Fukushima, would have been much less, if the alternative of the shelter in place protocol had instead been deployed.
According to reinsurer Munich Re , the private insurance industry will not be significantly affected by the disaster. In March , a Japanese court ruled that negligence by the Japanese government had led to the Fukushima disaster by failing to use its regulatory powers to force TEPCO to take preventive measures.
By March , one year after the disaster, all but two of Japan's nuclear reactors had been shut down; some had been damaged by the quake and tsunami.
Authority to restart the others after scheduled maintenance throughout the year was given to local governments, which all decided against reopening them.
According to The Japan Times , the disaster changed the national debate over energy policy almost overnight. It also omitted a section on nuclear power expansion that was in the previous year's policy review.
The nuclear plant closest to the epicenter of the earthquake, the Onagawa Nuclear Power Plant , successfully withstood the cataclysm.
Reuters said it may serve as a "trump card" for the nuclear lobby, providing evidence that it is possible for a correctly designed and operated nuclear facility to withstand such a cataclysm.
One estimate is that even including the disaster, more years of life would have been lost in if Japan had used coal or gas plants instead of nuclear.
Many political activists have called for a phase-out of nuclear power in Japan, including Amory Lovins , who claimed, "Japan is poor in fuels , but is the richest of all major industrial countries in renewable energy that can meet the entire long-term energy needs of an energy-efficient Japan, at lower cost and risk than current plans.
Japanese industry can do it faster than anyone — if Japanese policymakers acknowledge and allow it". Sovacool asserted that Japan could have exploited instead its renewable energy base.
In contrast, others have said that the zero mortality rate from the Fukushima incident confirms their opinion that nuclear fission is the only viable option available to replace fossil fuels.
Journalist George Monbiot wrote "Why Fukushima made me stop worrying and love nuclear power. I now support the technology.
The electricity supply failed, knocking out the cooling system. The reactors began to explode and melt down. The disaster exposed a familiar legacy of poor design and corner-cutting.
Yet, as far as we know, no one has yet received a lethal dose of radiation. In September , Mycle Schneider said that the disaster can be understood as a unique chance "to get it right" on energy policy.
On the other hand, climate and energy scientists James Hansen , Ken Caldeira , Kerry Emanuel , and Tom Wigley released an open letter calling on world leaders to support development of safer nuclear power systems, stating "There is no credible path to climate stabilization that does not include a substantial role for nuclear power.
Canadian Solar received financing for its plans to build a factory in Japan with capacity of MW, scheduled to begin production in As of September , the Los Angeles Times reported that "Prime Minister Yoshihiko Noda acknowledged that the vast majority of Japanese support the zero option on nuclear power",  and Prime Minister Noda and the Japanese government announced plans to make the country nuclear-free by the s.
They announced the end to construction of nuclear power plants and a year limit on existing nuclear plants. Nuclear plant restarts must meet safety standards of the new independent regulatory authority.
On 16 December , Japan held its general election. Abe supported nuclear power, saying that leaving the plants closed was costing the country 4 trillion yen per year in higher costs.
Marchers had gathered more than 8 million petition signatures opposing nuclear power. From to the nation fired up at least eight new coal power plants.
Plans for an additional 36 coal stations over the next decade are the biggest planned coal power expansion in any developed nation. A number of nuclear reactor safety system lessons emerged from the incident.
The most obvious was that in tsunami-prone areas, a power station's sea wall must be adequately tall and robust. Nuclear power station operators around the world began to install Passive Autocatalytic hydrogen Recombiners "PARs" , which do not require electricity to operate.
Had such devices been positioned at the top of Fukushima I's reactor buildings, where hydrogen gas collected, the explosions would not have occurred and the releases of radioactive isotopes would arguably have been much less.
Unpowered filtering systems on containment building vent lines, known as Filtered Containment Venting Systems FCVS , can safely catch radioactive materials and thereby allow reactor core depressurization, with steam and hydrogen venting with minimal radioactivity emissions.
This system was built prior to Fukushima Daiichi. Upon a station blackout , similar to the one that occurred after Fukushima's back-up battery supply was exhausted,  many constructed Generation III reactors adopt the principle of passive nuclear safety.
They take advantage of convection hot water tends to rise and gravity water tends to fall to ensure an adequate supply of cooling water to handle the decay heat , without the use of pumps.
As the crisis unfolded, the Japanese government sent a request for robots developed by the U. The robots went into the plants and took pictures to help assess the situation, but they couldn't perform the full range of tasks usually carried out by human workers.
In response to this shortcoming, a series of competitions were hosted by DARPA to accelerate the development of humanoid robots that could supplement relief efforts.
Japanese authorities later admitted to lax standards and poor oversight. Public anger emerged over what many saw as "an official campaign to play down the scope of the accident and the potential health risks".
In many cases, the Japanese government's reaction was judged to be less than adequate by many in Japan, especially those who were living in the region.
Decontamination equipment was slow to be made available and then slow to be utilized. As late as June , even rainfall continued to cause fear and uncertainty in eastern Japan because of its possibility of washing radioactivity from the sky back to earth.
To assuage fears, the government enacted an order to decontaminate over a hundred areas where the level of additional radiation was greater than one millisievert per year.
This is a much lower threshold than is necessary for protecting health. The government also sought to address the lack of education on the effects of radiation and the extent to which the average person was exposed.
Previously a proponent of building more reactors, Prime Minister Naoto Kan took an increasingly anti-nuclear stance following the disaster.
In May , he ordered the aging Hamaoka Nuclear Power Plant closed over earthquake and tsunami concerns, and said he would freeze building plans.
In July , Kan said, "Japan should reduce and eventually eliminate its dependence on nuclear energy". On 22 August , a government spokesman mentioned the possibility that some areas around the plant "could stay for some decades a forbidden zone".
According to Yomiuri Shimbun the Japanese government was planning to buy some properties from civilians to store waste and materials that had become radioactive after the accidents.
He added that he could "understand the concerns of foreign countries over recent developments at the nuclear plant, including the radioactive contamination of seawater".
Due to frustration with TEPCO and the Japanese government "providing differing, confusing, and at times contradictory, information on critical health issues"  a citizen's group called " Safecast " recorded detailed radiation level data in Japan.
The group uses off-the-shelf Geiger counter equipment. A simple Geiger counter is a contamination meter and not a dose rate meter.
The response differs too much between different radioisotopes to permit a simple GM tube for dose rate measurements when more than one radioisotope is present.
A thin metal shield is needed around a GM tube to provide energy compensation to enable it to be used for dose rate measurements.
For gamma emitters either an ionization chamber, a gamma spectrometer or an energy compensated GM tube are required.
Members of the Air Monitoring station facility at the Department of Nuclear Engineering at the University of Berkeley , California have tested many environmental samples in Northern California.
The Summer Olympics torch relay will begin in Fukushima and the Olympic baseball and softball matches will be played at Fukushima Stadium , despite the fact that the scientific studies on the safety of Fukushima are currently in great dispute.
The international reaction to the disaster was diverse and widespread. Many inter-governmental agencies immediately offered help, often on an ad hoc basis.
The main finding of this mission, as reported to the IAEA ministerial conference that month, was that risks associated with tsunamis in several sites in Japan had been underestimated.
In the aftermath, Germany accelerated plans to close its nuclear power reactors and decided to phase the rest out by  see also Nuclear power in Germany.
Italy held a national referendum, in which 94 percent voted against the government's plan to build new nuclear power plants.
So far, however, the government has only earmarked one power station for closure — the aging plant at Fessenheim on the German border — which prompted some to question the government's commitment to Hollande's promise.
Industry Minister Arnaud Montebourg is on record as saying that Fessenheim will be the only nuclear power station to close. Nuclear power plans were not abandoned in Malaysia, the Philippines, Kuwait, and Bahrain, or radically changed, as in Taiwan.
China suspended its nuclear development program briefly, but restarted it shortly afterwards. The initial plan had been to increase the nuclear contribution from 2 to 4 percent of electricity by , with an escalating program after that.
China plans to triple its nuclear energy output to , and triple it again between and New nuclear projects were proceeding in some countries.
KPMG reports new nuclear facilities planned or proposed for completion by This is accomplished by incorporating specially designed additives to standard fuel pellets and replacing or altering the fuel cladding in order to reduce corrosion, decrease wear, and reduce hydrogen generation during accident conditions.
While research is still ongoing, on 4 March , the Edwin I. Three investigations into the Fukushima disaster showed the man-made nature of the catastrophe and its roots in regulatory capture associated with a "network of corruption, collusion, and nepotism.
In August , several top energy officials were fired by the Japanese government; affected positions included the Vice-minister for Economy, Trade and Industry ; the head of the Nuclear and Industrial Safety Agency, and the head of the Agency for Natural Resources and Energy.
In three former TEPCO executives, chairman Tsunehisa Katsumata and two vice presidents, were indicted for negligence resulting in death and injury.
And its effects could have been mitigated by a more effective human response. The Commission recognized that the affected residents were still struggling and facing grave concerns, including the "health effects of radiation exposure, displacement, the dissolution of families, disruption of their lives and lifestyles and the contamination of vast areas of the environment".
The purpose of the Investigation Committee on the Accident at the Fukushima Nuclear Power Stations ICANPS was to identify the disaster's causes and propose policies designed to minimize the damage and prevent the recurrence of similar incidents.
The panel's report faulted an inadequate legal system for nuclear crisis management, a crisis-command disarray caused by the government and TEPCO, and possible excess meddling on the part of the Prime Minister's office in the crisis' early stage.

A study on the effects of the accident on fish and marine products showed that the contamination level had decreased dramatically over time, though the radioactivity of some species, especially sedentary rockfish, remained elevated within the exclusion zone.
A second, but smaller, nuclear accident took place in August when approximately tonnes tons of irradiated water used in ongoing cooling operations in reactors 1, 2, and 3 was discharged into the landscape surrounding the Fukushima Daiichi facility.
TEPCO officials reported that the leak was the result of an open valve in the short barrier wall that surrounded several of the tanks used in radioactive water storage.
