  • Dataset on the 6-Year Radiocesium Transport in Rivers Near Fukushima
    www.nature.com/scientificdata oPEN Dataset on the 6-year radiocesium Data DescriptoR transport in rivers near Fukushima Daiichi nuclear power plant Keisuke Taniguchi 1,2 ✉ , Yuichi Onda 1, Hugh G. Smith 3, William Blake 4, Kazuya Yoshimura 5, Yosuke Yamashiki6 & Takayuki Kuramoto 2,7 Radiocesium released from the Fukushima Daiichi nuclear power plant (FDNPP) and deposited in the terrestrial environment has been transported to the sea through rivers. To study the long-term efect of riverine transport on the remediation process near the FDNPP, a monitoring project was initiated by the University of Tsukuba. It was commissioned by the Ministry of Education, Culture, Sports, Science, and Technology, and the Nuclear Regulatory Commission in June 2011, and was taken over by the Fukushima Prefectural Centre for Environmental Creation from April 2015. The activity concentration and monthly fux of radiocesium in a suspended form were measured in the project. This provides valuable measurement data to evaluate the impact of the accidentally released radiocesium on residents and the marine environment. It can also be used as verifcation data in the development and testing of numerical models to predict future impacts. Background & Summary A 9.0 magnitude earthquake on March 11, 2011, caused the Tokyo Electric Power Company’s Fukushima Daiichi nuclear power plant (FDNPP) to be damaged by a tsunami, causing a large accident that spread radioactive mate- rials into the environment1,2. Tis was the largest release of radioactivity into the environment since the Chernobyl nuclear power plant accident in 1986, and has been rated on the International Nuclear and Radiological Event Scale (INES) as a “Major Accident” by International Atomic Energy Agency (IAEA)3.

  • Challenges of Restoring and Rehabilitating Sewer Systems Damaged by the Great East Japan Earthquake and Tsunami
    Journal of JSCE, Vol. 5, 279-297, 2017 Special Topic - Restoration and Recovery from the 2011 Great East Japan Earthquake（ Invited Paper） CHALLENGES OF RESTORING AND REHABILITATING SEWER SYSTEMS DAMAGED BY THE GREAT EAST JAPAN EARTHQUAKE AND TSUNAMI Hiroyasu SATOH1 1Member of JSCE, Associate Professor, Graduate School of Frontier Sciences, The University of Tokyo (5-1-5 Kashiwanoha, Kashiwa, Chiba 277-8563, Japan) E-mail: [email protected] This is a review of the restoration and rehabilitation of sewer systems damaged by the Great East Japan Earthquake and Tsunami. The disaster caused serious damage to sewer systems, amounting to approxi- mately 470 billion JPY. The damage was mainly caused by the tsunami, but the damage due to liquefac- tion was also serious. The tectonic activity caused additional discharge loads to municipalities in coastal areas. The nuclear accident at Fukushima Daiichi Nuclear Power Plant also affected sewer systems in such forms as radio-contamination of sewage sludge and reduction of power supplies. In addition, migra- tion of users of sewer systems took place. In the restoration activities, sewage treatment plants (STPs) were restored step-by-step, and guidelines were developed to strengthen STPs against tsunamis. The ef- fectiveness of different countermeasures against earthquakes and liquefaction were examined, and new countermeasures were proposed. Software measures such as the introduction of business continuity plans and information technologies are recognized as effective measures for overcoming disasters. In particular, the sewer systems in Sendai City have been successfully restored and rehabilitated after the disaster, with different hardware and software measures. In contrast, sewer systems in small municipalities seriously damaged by the tsunami are still taking time to rehabilitate.

  • Fukushima Nuclear Disaster – Implications for Japanese Agriculture and Food Chains
    Munich Personal RePEc Archive Fukushima nuclear disaster – implications for Japanese agriculture and food chains Bachev, Hrabrin and Ito, Fusao Institute of Agricultural Economics, Sofia, Tohoku University, Sendai 3 September 2013 Online at https://mpra.ub.uni-muenchen.de/49462/ MPRA Paper No. 49462, posted 03 Sep 2013 08:50 UTC Fukushima Nuclear Disaster – Implications for Japanese Agriculture and Food Chains1 Hrabrin Bachev, Professor, Institute of Agricultural Economics, Sofia, Bulgaria2 Fusao Ito, Professor, Tohoku University, Sendai, Japan 1. Introduction On March 11, 2011 at 14:46 JST the Great East Japan Earthquake occurred with the epicenter around 70 kilometers east of Tōhoku. It was the most powerful recorded earthquake ever hit Japan with a magnitude of 9.03 Mw. The earthquake triggered powerful tsunami that reached heights of up to 40 meters in Miyako, Iwate prefecture and travelled up to 10 km inland in Sendai area. The earthquake and tsunami caused many casualties and immense damages in North-eastern Japan. According to some estimates that is the costliest natural disaster in the world history [Kim]. Official figure of damages to agriculture, forestry and fisheries alone in 20 prefectures amounts to 2,384.1 billion yen [MAFF]. The earthquake and tsunami caused a nuclear accident3 in one of the world’s biggest nuclear power stations - the Fukushima Daiichi Nuclear Power Plant, Okuma and Futaba, Fukushima prefecture. After cooling system failure three reactors suffered large explosions and level 7 meltdowns leading to releases of huge radioactivity into environment [TEPCO]. Radioactive contamination has spread though air, rains, dust, water circulations, wildlife, garbage disposals, transportation, and affected soils, waters, plants, animals, infrastructure, supply and food chains in immense areas.

  • Temporal Trends for Dioxins-Related Agrochemicals in Sediments in a Large-Scale Rice-Producing Area, Niigata, Japan
    LEVELS IN SOIL AND WATER TEMPORAL TRENDS FOR DIOXINS-RELATED AGROCHEMICALS IN SEDIMENTS IN A LARGE-SCALE RICE-PRODUCING AREA, NIIGATA, JAPAN Mizuki Sakai1, Muto Hiroaki2, Kajihara Hideo1, Takahashi Yukio2 1Graduate School of Science and Technology, University of Niigata, 2-8050 Ikarashi, Niigata, Japan 2Faculty of Engineering, University of Niigata, 2-8050 Ikarashi, Niigata, Japan Introduction Japanese people have historically eaten rice as the main grain constituent in their diet. In Sea of Japan the past 50 years, a larger amount of agrochemicals have been applied to Japanese rice fields to increase rice production. Masunaga et al. reported that common Toyano Lagoon Agano Japanese agrochemicals such as River pentachlorophenol (PCP) and chloronitrophen (CNP) used in rice fields in the past contain Shinano Kameda basin dioxins as impurities 1. Since Niigata Plain is River the largest rice-producing area in Japan, the soil and/or sediment in the lower basin in 5km Niigata Plain could be highly polluted. In the previous study, we measured the age of a sediment core and the amount of dioxins (PCDD/DFs) in Toyano Lagoon and estimated the historical trend and the sources of dioxin2. Most of the sources of dioxin in Toyano Lagoon sediment were PCP and CNP. The aims of this work are to quantify the extent, clarify the historical trends of CNP and PCP pollution in the Toyano Lagoon sediment and consider the interrelation between them.
