Psychiatric Problems

After the accident at the Fukushima nuclear power plant in 2011, caused by the Great East Japan Earthquake, some evacuees had no one to consult despite many local care providers offering assistance. This study identified the characteristics of individuals who did not receive consultations and the relevant determinants, and proposed the available measures to address this issue. Altogether, 32,699 participants aged 16 years or older and residing in the disaster area at Fukushima were surveyed. Those with no one to consult showed a significantly higher prevalence of psychological distress (16.2%, p < 0.001) and drinking problems (21.5%, p < 0.001). Multivariate analysis revealed that these behaviors were associated with the middle age group (i.e., 40–64 years old) (odds ratio [OR]: 1.30; 95% confidence interval [CI]: 1.16–1.46), men (OR = 2.46; 95% CI, 2.27–2.66), bad financial circumstances (OR = 2.11; 95% CI, 1.96–2.27), and living alone (OR = 1.53; 95% CI, 1.39–1.68). This research verifies that people with such characteristics were more likely to be isolated and vulnerable to psychiatric problems, such as depression. We suggest that it is integral for local care providers to recognize those who have no one to consult and provide targeted support.

The Fukushima nuclear disaster has raised the importance on the reliability and risk research of the spent fuel pool (SFP), including the risk of internal events, fire, external hazards and so on. From a safety point of view, the low decay heat of the spent fuel assemblies and large water inventory in the SFP has made the accident progress goes very slow, but a large number of fuel assemblies are stored inside the spent fuel pool and without containment above the SFP building, it still has an unignored risk to the safety of the nuclear power plant. In this paper, a standardized approach for performing a holistic and comprehensive evaluation approach of the SFP risk based on the probabilistic safety analysis (PSA) method has been developed, including the Level 1 SFP PSA and Level 2 SFP PSA and external hazard PSA. The research scope of SFP PSA covers internal events, internal flooding, internal fires, external hazards and new risk source-fuel route risk is also included. The research will provide the risk insight of Spent Fuel Pool operation, and can help to make recommendation for the prevention and mitigation of SFP accidents which will be applicable for the SFP configuration risk management.

What happens when expertise is forced to face disasters of unprecedented scales? How is knowledge produced in critical moments when every action and decision is a matter of life and death? And how are local social networks mobilized to cope with unforeseen crisis? This paper addresses these questions by examining the emergence of disaster medicine expertise in the aftermath of Fukushima nuclear disaster that struck Japan in 2011. Studies on Fukushima’s impact have to date revolved around the suffering of Tōhoku citizens and the development of Japan’s nuclear energy industry. Acknowledging the gravity of such work, this paper offers an alternative, but equally crucial angle on the disaster: that of the medical caregiving and public health system built in response to radiation hazards resulting from the triple meltdowns at Fukushima Daiichi nuclear power station. Through detailed interviews conducted with eight medical practitioners in Fukushima Prefecture, this paper analyses the significance and impact of Japan’s most recent radiation disaster on its public health infrastructure. To describe the contingent nature of radiation disaster medicine developed in response to radiation risk in Fukushima, we draw on Jasanoff’s characterization of scientific knowledge as ‘serviceable truths’ with regards to public policy and the law, suggesting that expertise in relation to disasters is usefully understood in analogous terms.

Fukushima Nuclear Disaster

AbstractOfficial investigations that followed the Fukushima Nuclear Disaster revealed that it could have been prevented by reasonable safety measures. Investigators concluded that close relationships between government officials and industry executives led to very weak regulatory oversight and the failure to address the risk of violent earthquakes and tsunami such as those that struck the Fukushima Nuclear Power Station on March 11, 2011. News reporters conducted their own investigations in the months following the disaster. Japan’s information disclosure law provided an invaluable tool that enabled them to obtain government records related to regulation of Japan’s nuclear power plants. This article describes some of the stories they produced. Appearing on the front pages of newspapers with daily circulations in the millions, this work provided an authoritative inside view of the failed regulatory process to the Japanese people. The work of the investigative bodies and the news media drove the demand for change that led to disbanding of the regulatory agencies that failed and their replacement by an entirely new regulatory body. This article highlights the importance of “right to know” laws such as Japan’s information disclosure law in creating the opportunity for news reporters and others to demand the release of otherwise confidential government records that can enlighten everyone on matters of great public interest.

Fukushima Nuclear Disaster

AbstractLiterature expects that an attitude toward nuclear power is in direct proportion to the perceived risk of accidents at an operational nuclear power plant; that is, the oppositional attitude is based on the view that nuclear technology is risky and support for nuclear power is related to a perceived low risk and/or potential benefit. However, it is misleading to assume that individuals’ risk perception alone can linearly explain their position after such an accident. The association between risk perception and attitude toward nuclear power varies significantly according to country but, until now, has been largely unexamined. This article takes into consideration the effects of structural factors on that relationship by examining public attitudes toward nuclear energy after the Fukushima nuclear accident in March 2011 and reveals that the need for the efficient production of electricity (i.e., nuclear energy) outweighs concern for the potential danger of a nuclear incident. Although a country's dependence on nuclear power for the production of electricity engenders anti-nuclear attitudes, it is evident that a level of economic development largely alleviates any negativity relative to that energy source.

BACKGROUND YouTube (Alphabet Incorporated) has become the most popular video-sharing platform in the world. The Fukushima Daiichi Nuclear Power Plant (FDNPP) disaster resulted in public anxiety toward nuclear power and radiation worldwide. YouTube is an important source of information about the FDNPP disaster for the world. OBJECTIVE This study's objectives were to examine the characteristics of YouTube videos related to the FDNPP disaster, analyze the content and comments of videos with a quantitative method, and determine which features contribute to making a video popular with audiences. This study is the first to examine FDNPP disaster–related videos on YouTube. METHODS We searched for the term “Fukushima nuclear disaster” on YouTube on November 2, 2019. The first 60 eligible videos in the relevance, upload date, view count, and rating categories were recorded. Videos that were irrelevant, were non-English, had inappropriate words, were machine synthesized, and were &lt;3 minutes long were excluded. In total, 111 videos met the inclusion criteria. Parameters of the videos, including the number of subscribers, length, the number of days since the video was uploaded, region, video popularity (views, views/day, likes, likes/day, dislikes, dislikes/day, comments, comments/day), the tone of the videos, the top ten comments, affiliation, whether Japanese people participated in the video, whether the video recorder visited Fukushima, whether the video contained theoretical knowledge, and whether the video contained information about the recent situation in Fukushima, were recorded. By using criteria for content and technical design, two evaluators scored videos and grouped them into the useful (score: 11-14), slightly useful (score: 6-10), and useless (score: 0-5) video categories. RESULTS Of the 111 videos, 43 (38.7%) videos were useful, 43 (38.7%) were slightly useful, and 25 (22.5%) were useless. Useful videos had good visual and aural effects, provided vivid information on the Fukushima disaster, and had a mean score of 12 (SD 0.9). Useful videos had more views per day (<i>P</i>&lt;.001), likes per day (<i>P</i>&lt;.001), and comments per day (<i>P</i>=.02) than useless and slightly useful videos. The popularity of videos had a significant correlation with clear sounds (likes/day: <i>P</i>=.001; comments/day: <i>P</i>=.02), vivid information (likes/day: <i>P</i>&lt;.001; comments/day: <i>P</i>=.007), understanding content (likes/day: <i>P</i>=.001; comments/day: <i>P</i>=.04). There was no significant difference in likes per day (<i>P</i>=.72) and comments per day (<i>P</i>=.11) between negative and neutral- and mixed-tone videos. Videos about the recent situation in Fukushima had more likes and comments per day. Video recorders who personally visited Fukushima Prefecture had more subscribers and received more views and likes. CONCLUSIONS The possible features that made videos popular to the public included video quality, videos made in Fukushima, and information on the recent situation in Fukushima. During risk communication on new forms of media, health institutes should increase publicity and be more approachable to resonate with international audiences.

Many thought that the 11 March 2011 Fukushima nuclear disaster in Japan might be the end of the “global nuclear renaissance.” In Europe, mass media after Fukushima increasingly presented negative framing of nuclear energy and highlighted declining support for the nuclear industry. In the United States, however, nuclear production and public support for the industry remained steady. This article analyzes US media documents to understand the construction of public discourse on nuclear power in the wake of the Fukushima disaster. Through a content analysis of US newspapers, it demonstrates that post-Fukushima media framed the crisis in a way that privileged expert knowledge and opinion, while delegitimizing non-expert engagement with nuclear energy issues. A comparison between national newspapers and newspapers located in two regions with controversial nuclear plants and active anti-nuclear citizens’ movements additionally demonstrates the power and reach of the identified framework across the spectrum of views on nuclear power.

Fukushima Nuclear Disaster

Since the Fukushima nuclear disaster in 2011, much attention has been paid to investigation of severe accidents (SA) progression in spent fuel pools (SFP) of various types of nuclear power plants (NPP). In Czech Republic, 4 VVER-440 and 2 VVER-1000 types of reactors (at the Dukovany and Temelin NPPs, respectively) are currently under operation. In order to enhance their safety, especially with respect to station black-out (SBO) events, numerical analyses have been carried out evaluating the risks associated with accidents occurring also in the SFP. The present paper deals with analyses of 2 postulated scenarios (loss of cooling and loss of coolant) and is mainly focused on the input deck preparation for the integral, lumped parameter (LP) code for SA analyses — MELCOR 1.8.6. Emphasis is put on description of correct implementation of the complex geometry of the SFP, consisting of 3 distinct pools separated by concrete walls (lined with steel plates) in which fuel assemblies (FA) are stored in an absorber grid (rack). In the description of the prepared numerical model, light is shed on the encountered modeling issues, and corresponding hints and solutions are proposed in order to provide guidance for preparing adequate models for various types of SFP designs. Finally, some of the most characteristic results are presented for both postulated scenarios.
