Most of large earthquakes occur in the subduction zone below the Pacific Ocean. However M~7 earthquakes sometimes occur in the interior of Japan, and cause serious damage and disruption to society. Most geologists and geophysists believe that two continental plates, that is, the North American and Amurian plates are bounded by the Itoigawa-Shizuoka Tectonic Line (ISTL), which is a major geological boundary in central Japan. However, GPS studies suggest that contemporary deformation is concentrated in a northeast-southwest trending zone called the Niigata-Kobe Tectonic zone (NKTZ) [Sagiya et al., 2000]. The Chuetsu (Mid-Niigata) area in the northern part of the NKTZ is one of the most active tectonic regions, in which a fold-and-thrust belt is well developed. Geological studies [Okamura et al., 1995; Ikeda et al., 2002; Sato et al., 2004] suggest that thick sediments accumulated in a rift system which formed in an extensional stress regime during back-arc spreading. These sediments are related to the opening of the Sea of Japan from 25–13 Ma BP. Normal faults formed at this stage have been subsequently activated as reverse faults during shortening in the eastern margin of the Japan Sea in the past 3.5 Ma. The 2004 M=6.8 Mid-Niigata Prefecture (Chuetsu) and the 2007 M=6.8 Niigataken Chuetsu-oki earthquakes ruptured such reverse faults. (See also supplemental figures in Appendix 1) Fig. 0-1 Tectonic setting and large earthquakes of the Japanese islands [modified from Sagiya(2004)]. Arrows show relative plate motions based on REVEL 2000 [Sella et al., 2002]. Red areas show the epicentral areas of large earthquakes after 1994. 2 STOP 1: Nagaoka City Yamakoshi Hall STOP 2: Kogomo village, Yamakoshi Higashi-takezawa district The 2004 Mid Niigata Prefecture Earthquake (M 6.8) with a recorded seismic intensity of 7 (JMA scale) caused huge damage in the Chuetsu region. A massive landslide occurred on the left bank of the Imo River displacing a huge soil mass, and blocked the river in the Yamakoshi Higashi-takezawa district.

    Introduction and Main Conclusions Introduction

    INTRODUCTION AND MAIN CONCLUSIONS INTRODUCTION At the request of the government of Japan, an IAEA Operational Safety Review Team (OSART) of international experts visited units 6 and 7 of the Kashiwazaki-Kariwa Nuclear Power Station from 29 June to 13 July 2015. The purpose of the mission was to review operating practices in the areas of Leadership and Management for Safety, Training and Qualification; Operations; Maintenance; Technical Support; Operating Experience; Radiation Protection including Post Accident Sampling; Emergency Planning and Preparedness and Severe Accident Management. In addition, an exchange of technical experience and knowledge took place between the experts and their plant counterparts on how the common goal of excellence in operational safety could be further pursued. Kashiwazaki-Kariwa nuclear power station is located almost at the centre of Niigata Prefecture between Kashiwazaki City and Kariwa Village on the coast of the Sea of Japan. The site covers an area of around 4.2 million square metres and is encircled by a hilly area of pine forest. Kashiwazaki city, to the south, has a population of approximately 92000 and Kariwa village, to the east, approximately 5000. There are seven units on the site; all operated by the Tokyo Electric Power Company (Tepco), Units 1 to 5 are 1100 MWe BWR5 Reactors. Unit 1 has a Mark II containment vessel, units 2 to 5 have Mark II advanced containment vessels. Units 6 and 7 are 1356 MWe Advanced BWRs in ABWR containments. Units 1 to 5 were commissioned between 1985 and 1990, Unit 6 entered commercial operation in 1996 and Unit 7 in 1997.

    ABWR Operation Experience at Kashiwazaki-Kariwa NPS Tatsuro KOBAYASHI1*, Kimitoshi YAHAGI2, Masumi ISHIKAWA3, and Hideya KITAMURA4 1, 2, 3Kashiwazaki Kariwa Nuclear Power Station, TEPCO, 16-46 Aoyama-cho, Kashiwazaki-shi, Niigata 945-0393, Japan 4Tokyo Electric Power Company, 1-3-1 Uchisaiwai-cho, Chiyoda-ku, Tokyo 100-8560, Japan The world’s first advanced boiling water reactors (ABWR), Kashiwazaki-Kariwa NPS unit 6 and 7 of twin 1,356 MWe, have continued safe and reliable operation contributing to not only supplying the Tokyo metropolitan area with electricity but also securing energy resources and reducing greenhouse gas emissions. The ABWR, which was jointly developed by GE, Toshiba, Hitachi and TEPCO based on the construction and operation experiences of conventional BWRs, could be integrated with various features, such as enhanced safety, reliability, improved operability, maneuverability, economy, reduced occupational radiation exposure and radioactive wastes. Those features have been demonstrated as expected through operation and outage experiences since 1996. Although we had experienced several unplanned shutdowns in unit 6 and 7, the root causes of these shutdowns were almost due to the conventional problems, such as the failure of electrical instrument, plant auxiliary system, or fuel failure. Thus, we will make every effort to continue excellent operation and we hope that the experience obtained at Kashiwazaki-Kariwa unit 6 and 7 is used for future development of the ABWR. KEYWORDS: ABWR, RIP, RCCV, Digitalized Main Control Room I.

    Impacts of the Niigataken Chūetsu-Oki Earthquake to the Kashiwazaki-Kariwa Nuclear Power Plant, Post-Earthquake Response, and Lessons Learned: U.S. Perspective for Design Basis Earthquakes and Beyond Design Basis Earthquakes James J. Johnson1, Antonio R. Godoy1, Aybars Gürpinar1, Roger M. Kenneally2 1James J. Johnson and Associates 2Independent Consultant “2016 Natural Phenomena Hazards Meeting and Training Session” 18-19 October 2016 Germantown, Maryland Abstract Over the years, a number of nuclear power plants (NPPs) in Japan have experienced earthquake shaking and some have experienced shaking in multiple earthquakes. The U.S. Nuclear Regulatory Commission (NRC) has identified a need to better understand the seismic performance of Japanese NPPs and to determine if any important lessons should be applied to NPPs in the United States (U.S.). On July 16, 2007, a strong earthquake, the Niigataken Chūetsu-Oki (NCO) earthquake, with a moment magnitude (M) of M6.6 occurred approximately 16 km north of the Kashiwazaki-Kariwa Nuclear Power Plant (KKNPP). KKNPP has seven NPP units that experienced the NCO earthquake ground motions. Numerous seismic instruments located at the KKNPP recorded motions from the NCO earthquake in the free-field, on foundations, and in-structures. The recorded motions showed that the NCO earthquake motions significantly exceeded the plant design basis earthquake ground motion response spectra. Although no safety-related structures, systems, and components (SSCs) experienced damage, non-safety-related SSCs experienced significant damage. This presentation reviews the effects of the NCO earthquake on the KKNPP, with the objective to assess whether the potential for similar behavior (both positive and negative) is expected of U.S.

    A Mediator Between Young People and Local Companies to Save Our Town

    A Mediator Between Young People and Local Companies to Save Our Town 3103 Mimi Iwata Introduction A decline in population is one of the biggest problems in Japan, especially in the countryside. Minamiuonuma city, located in the southern part of Niigata prefecture, is greatly influenced by this phenomenon. It is inevitable for Minamiuonuma city to overcome this problem. In Minamiuonuma city, the number of young people is so few. The city hall has been carrying out some new policies that encourage young generation to come back, but they have not resulted well yet. So we need something new to address this problem. Problems The problem in Minamiuonuma city is the lack of young human resources. It leads to the decline in its industry and citizens will have difficulty living in, eventually. It will be difficult to improve the city’s overall industry. According to the survey of the Ministry of Internal Affairs and Communications (2017), the population of Minamiuonuma city decreased by 11.0% from 2000 to 2015. Seirou-machi, located in Niigata city, increased by 5.0%. Seirou-machi has the highest rate of increase in the population in Niigata prefecture. The population of 15 to 34 year-olds dexreased by 13% in Minamiuonuma city and has not so changed in Seirou-machi. It can be said that there is a big gap between Minamiuonuma city and Seirou-machi even if these two cities are located in the same prefecture. So we have to diminish the gap and solve the lack of young people. Solutions To solve this situation, I suggest introducing a UTA system, which stands for Uonuma Tactic Association.
