The Great East Japan earthquake and the resulting tsunami struck Japan east coast on March 11th 2011. All nuclear power plants on the east coast were automatically shut down, and several thermal plants were damaged: Japan was left with only 19% of its nuclear capacity available (i.e. 9 GW). The Fukushima-Daiichi nuclear power plant underwent major incidents, with a fusion of the nuclear core and radioactivity leakage, the most important nuclear accident since Chernobyl. During the summer 2011, the Japanese government undertook emergency measures to offset the expected 20% capacity shortage in Tokyo and Tohoku areas. On the supply side, capacity was recovered by restarting and restoring fossil-fuelled power generation, and importing power from neighboring areas. On the demand side, stringent demand restriction measures led to a summer peak demand 10 GW lower in the Tokyo area and 3.1 GW lower in the Tohoku area, compared to 2010. In early 2012, only 2 reactors were still in operation, after further nuclear shutdowns. Market-driven electricity conservation reforms and subsidy-driven supply capacity additions aim to avoid emergency measures in the summer 2012 similar to those of summer 2011, and offset the expected 9% power deficit in the country. For the longer term, Japan government has launched various initiatives to review the 2010 Basic Energy Plan, which envisaged a nuclear expansion. In this study, a model was developed to assess the economic and environmental impacts of three contrasted scenarios, reflecting different options for Japan’s electricity mix by 2050. The results show that a nuclear phase-out would induce additional costs of the order of €850bn to the power system over the period 2010-50, compared to the Basic Energy Plan, while also preventing Japan to reach its CO2 emissions’ reduction targets by 2050. A sensitivity analysis shows that a reduced renewables development would lower the cost of the power system, but put aside climate change mitigation and energy security of supply. On the other hand, a reduced electricity demand through energy efficiency measures would have a positive impact on both CO2 emissions and the security of supply. / <p>-</p> / -

"Representation of nuclear energy in media in the period before and after the accident in Fukushima" This master's thesis examines media representation of nuclear energy within one year before and one year after the Fukushima Nuclear Disaster. The sample of news was selected from the print edition of the two main Czech dailies - MF Dnes and Právo. The method used in the thesis is content analysis. In the first part, some of the main theories of media studies (agenda setting, stereotypes, framing, and moral panic) and mechanisms which single news are constructed by (news values, access to news, primary defining, and gatekeeping) are introduced. In the second part, shift in both the focus of the media on the issue of nuclear energy and utilizing of the selected mechanisms of construction of the news is examined. In conclusion, the thesis identifies how the representation of the nuclear energy is constructed in the above said dailies over the period given before and after the Fukushima nuclear disaster.

Abstract The purpose of this study was to research the local opinion of nuclear power in the city of Gävle in the shadow of the nuclear catastrophes in Chernobyl (1986) and Fukushima (2011). In 1986, Gävle was, in Sweden, the worst afflicted by the radiation from Chernobyl’s meltdown. This, alongside the referendum of 1980, triggered a strong opposition to the nuclear power industry and many wanted to see that all the Swedish nuclear power-plants were discontinued. In 2011, the last date set, for a complete decommission of the Swedish nuclear power, by the referendum of 1980 has passed. And in the shadow of Fukushima, the opinion regarding to the dangers of nuclear powers has been shifted. This study uses to two local newspapers of Gävle, Arbetarbladet and Gefle Dagblad to study the effects the two different nuclear meltdowns had on the people of Gävle during 1986 and 2011. The analyze categories the local papers writing into three aspects: One of information, one of opinion and one of politics. And to support its conclusions it refers to Ulrich Beck’s theory of the risk society and the reflexive modernism. As well as a Swedish study about the Swedish peoples trust in nuclear power during the period of 1986 to 2009.   Keywords: Nuclear Power, Opinion, Chernobyl, Fukushima, Gävle, Risk society, Reflexive Modernism, Ulrich Beck.

Die Schauspieler der japanischen Theatergruppe Marebito Theatre Company reisten 2012 von Tokio aus in die geschädigten Gebiete Fukushima und Minami-Soma. Diese Reise war der erste Teil ihres Theaterprojekts "Aufzeichnung einer Reise zu Antigone und deren Aufführung". Die Gruppe versuchte in diesem Projekt, sich mit dem großen Ereignis vom 11. März 2011 und der Erinnerung daran zu beschäftigen. Sie versuchte, sich dem Ort, der vom Tōhoku-Erdbeben 2011 und der Nuklearkatastrophe von Fukushima betroffen wurde und dieser Zeit anzunähern.

Den 11 mars 2011 inträffade en kärnenergiolycka i Fukushima, Japan. Jag har gjort en diskursanalytisk innehållsanalys av fyra svenska dagstidningars artiklar om kärnenergi från de 90 dagarna innan kärnenergiolyckan i Japan, de första 90 dagarna efter den samt de därefter följande 90 dagarna. Jag har även jämfört de tendenser som framkommer i rapporteringen med Sveriges befolknings attityder till kärnenergi för att se om det finns något samband mellan dessa. Syftet var att utifrån mina resultat, tidigare forskning och teorin från forskningsfältet ”communication of science” analysera den eventuella påverkan medias rapportering om kärnenergi och allmänhetens syn på kärnenergi kan ha på varandra. Analysen visar att det finns ett samband mellan tidningarnas rapportering och allmänhetens åsikter och att det är troligt att parterna påverkar varandra. Vidare studier skulle dock krävas för att säkert kunna uttala sig om hur parterna påverkar varandra.

The thesis deals with the knowledge of the population about the nuclear disaster at Fukushima in the Vysočina Region. The goal is to determine the level of knowledge of population about the accident and then compare the knowledge of people aged 18-44 years and older than 45 years. In the thesis were set two hypotheses, H1: the knowledge of the population in the nuclear accident will be close to normal distribution and H2: people under 45 years will have statisticly higher knowledge than older people. To achieve the setted goals and to test the hypotheses, a questionnaire was compiled and a survey was made. The results of the survey were evaluated by methods of descriptive and mathematical statistics. The questionnaire consisted of 11 questions. The survey consisted of 100 people aged 18-44 years and 100 people aged over 45 years. The results of the survey show that the overall percentage of correctly answered questions was 63,3 %, which can be considered slightly above average. 66,1 % of people aged 18-44 years answered the questions correctly and residents over the age of 45 years 60,6 % correctly. The set goals were achieved and both hypotheses were confirmed. The benefit of this thesis is to obtain a picture of knowledge of public in the nuclear disaster at Fukushima in the Vysočina Region. The results can also be used for crisis management authorities within the preparation and preventive educational activities focused on the issue of nuclear energy and radiation protection.

The aim of this study is to compare the cause of the, to date, three onlycommercial nuclear power plant accidents. These are very complex incidents,which have dire impact on society and the environment and therefore benefitfrom further investigation, if there lays a possibility of identifying factors thatcould prevent further accidents in the future. In order to investigate this theactions and decisions that lead up to each nuclear meltdown was identified andcompared.The investigation was based on a qualitative study on three cases of nuclearmeltdown accidents. They are based on text analysis of official reports anddocumentaries on the subject. The theoretical background for this study wasKajtazi’s (2011) work on Information Inadequacy. The study was limited to theevents leading up to the accidents and do not include activities afterwards.The study shows that each case had different underlying reasons. It alsoshows that we seem to have learned something from our previous mistakes, andacted on them accordingly. From the Fukushima Daiichi accident we canrecommend that organizations in charge should take early warnings seriouslyand act upon them as soon as they are presented.
