Dataset

Description국내 원자력관련 최신동향 발표자료 목록 데이터 입니다. 데이터 칼럼 리스트는 저자, 제목, 출처, 출신지, 페이지, 언어, 소속, 출처, 개최지, 일시, 키워드, 초록 입니다. (연구자가 과학기술분야의 최신 정보를 최단시간에 입수하기 위해서는 가장 적합한 매체는 회의자료이므로 국내에서 개최된 원자력관련 회의 (한국원자력학회, 한국방사성폐기물학회, 한국기계학회 등의 춘추계 학술발표회 및 한국방사선동위원소, 전자빔응용 워크샾 등)와 2개 이상 국가가 참여한 국제회의(한국원자력협회-일본원자력협회의 원자력산업 세미나, 레이저분광학 국제심포지엄 등)가 있으며 주로 발표한 논문, 프레젠테이션 형태의 자료들의 목록)

1st rowNuclear licensees have been phasing in and implementing procedures for the regulation to comply with the standard, KINAC/RS-015. As one of the activities of the regulation, nuclear facilities licensee shall carry out the continuous assessment of the cyber security controls at least at every overhaul period to validate that the security controls developed according to the cyber security controls of KINAC Regulatory standard (RS-015) are actually applied on the site and properly working. In addition, nuclear facilities licensee shall also evaluate whether the previously established cyber security controls are effectively working in continuously changing cyber threat and environment. This paper presents how the U.S. nuclear licensees perform cyber security self-assessment and regulator's perspective to introduce and apply the method to the ROK's nuclear facilities. The cyber security self-assessment method was specifically designed for cyber security evaluations of nuclear facilities. The method can be used by l
2nd rowThis issue about human resource is a burden not only for IAEA but also for facility operator. Therefore, it is necessary to develop algorithm that automatically detect normal and abnormal conditions in order to introduce many surveillance devices while minimizing manpower. In this study, the algorithm development was performed by using the hypothetical surveillance camera in electro-refining cell, which is the main process cell of pyroprocessing. The key technology to check operation condition automatically is to detect any object to classify normal and abnormal conditions. The movement of a crane can be an important factor in monitoring within electro-refining cell. The algorithm to detect the crane, which indicates transportation of process materials in main processes, has been developed based on the hypothetical video data showing process condition in the electro-refining cell. The study on detecting a crane in the hypothetical video obtained surveillance camera was performed. The machine learning techniqu
3rd rowAccording to the emerging change on national energy transition policy in the Republic of Korea, the interest on radiation safety of domestic nuclear field has been increased. In response, it is crucial to identify the competence of human resource (HR) that could contribute to safety of radiation facility. Full scale enumeration on nuclear engineering related academic and research area had been pre-studied.The present survey analysis research is aimed to estimate expectation of human resource supply and demand on KAERI, KINS, KINAC and KHNP Central Research Institute so as to evaluate its balance status for long term stable HR management for ensuring and enhancing the radiation safety. The difference in nuclear power portion between the 4th and 8th basic plan for long-term electricity supply and demand makes difference to the HR supply. Which also leads to decreasing of HR demand from 2025 year both on KAERI and KINS. For keeping continuous balance on supply and demand of radiation safety management human reso
4th rowA safeguards approach of the intermediate-sized pyroprocessing facility is being developed. The safeguards measures in the safeguards approach are based on the current IAEA equipment and the safeguards technology under development. The NRTA is applied to the specified area of the REPF+. The process monitoring and the C/S on the material and equipment transfer door are included to increase the effectiveness. Safeguards approach is a set of safeguards measures to allow the IAEA to meet the applicable safeguards objectives. Safeguards approaches of the existing nuclear material handling facilities were already developed, and a safeguards approach of a pyroprocessing facility is required for the effective and efficient safeguards implementation in the pyroprocessing facility. Korea Atomic Energy Research Institute (KAERI) developed the safeguards approach of a reference facility named Reference Engineering-scale Pyroprocessing Facility (REPF) in collaboration with Korea Institute of Nuclear Nonproliferation and C
5th rowOverall safeguards activities were reviewed to be carried out during whole-life of nuclear facility. This study is applicable to most of nuclear facilities such as reactors, fuel fabrication plant, and others. Though some kind of facilities can be discussed with IAEA additionally, the above explained safeguards activities should be carried out in the legal basis. In the safeguards aspect, the status of facility function and nuclear material is the most important components. Recent issues in domestic nuclear fields are related to the decommissioning and dismantling of nuclear facilities. But safeguards activities during dismantling stage are only a part of safeguards during whole-life of facility. In this paper, safeguards implementation activities under legal basis are investigated during the wholelife of nuclear facility including the decommissioning and dismantling stage. Overall safeguards activities were reviewed to be carried out during whole-life of nuclear facility. This study is applicable to most of

Neutron transmutation doping (NTD) of semiconductors is an important method for applications that require high dopant homogeneity, for example in electric power devices. For neutron transmutation doping, SiC is irradiated by neutron and the components of SiC become radioactive nuclides. These radioactive nuclides can be a problem for safety and quality control. In this study, assessment of residual radioactivity after neutron irradiation of SiC is conducted using Monte Carlo simulation and most influential component is discussed. Assessment for residual radioactivity after neutron irradiation of SiC is conducted using PHITS simulation. As a result, aluminum that is an impurity in SiC has dominant residual radioactivity and ambient dose equivalent after neutron irradiation. Thus the concentration of a

In this study, a simple method to estimate the depth distributions of nuclides was developed by calculating the individual dose rate of detected gamma nuclides at 1 m above the ground. The dose rate spectroscopy was then used to previously determine the individual dose rate of "1"3"7Cs from the measured energy spectrum using a portable HPGe detector. In addition, theoretical individual dose rates of "1"3"7Cs at 1 m above the ground were calculated by assuming several depth distributions of "1"3"7Cs in the ground. The real depth distribution of "1"3"7Cs was determined from the comparison between them. Its radioactivity in the ground was then calculated by applying the dose conversion factor in the unit of nGy/h/Bq/m"2 in the condition of the determined depth distribution.

Although laponite shares a 2:1 silicate structure with the smectite natural clays such as montmorillonite, its primary particles are fairly monodispersed with a disk-like shape having diameter in the range 25-30 nm and thickness of 0.92 nm. So, it offers a large area of surface binding sites, particularly from the edge of the platelet structures. At low concentration it can form a homogeneous and transparent aqueous solution depending on pH and electrolyte concentrations (ionic strength). Thus, U(VI)-laponite system can be a good model system for investigating U(VI)-clay interactions and speciation using TRLFS. By using a synthetic nano-clay mineral material (laponite) and TRLFS techniques the fundamental sorption behaviors of U(VI) were investigated.

The aim of the present work is to determine the isotopic compositions and its contents of Ce for the samples from sintered solid and annular pellets of PWR type irradiated in the Hanaro reactor at KAERI, and to determine the total burnup using the measured results, so as to determine the respective validity of the methods. The contents of U, Pu, Nd, Ce and their isotopes in irradiated pellet samples and the total burnup by using Nd and Ce isotope monitors can be determined simultaneously by the isotope dilution mass spectrometric techniques. The Nd and Ce isotope patterns provide information on the real irradiation characteristics which are necessary for evaluating a fuel's performance in
