[en] Nuclear Training Center (NTC) has concentrated its efforts on the systemization and specialization of education and training programs and has actively carried out diverse activities to create new nuclear courses based on its experience accumulated over the past years. The systematic and comprehensive education systems have been set up by streamlining the education systems for internal employees conducted sporadically over the past years. For the development of efficient education courses, expansion and diversification of education and training programs have been carried out based on the study of the Systematic Approach to Training (SAT) methodology and a survey of manpower development in on-site industry. Furthermore, despite the decrease in the number of potential trainees due to various government-enforced regulations and the increase in the number of other nuclear education institutions, the consistent efforts to develop new courses and to improve previous programs based on evaluations from the trainees have led to an upgrade in the level of education and the efficiency of the operation compared to previous years. In terms of development, 7 education programs were improved accordingly and 10 new courses were created. The year 2008 was especially considered a landmark, as NTC was authenticated as one of the best Human Resource Development (HRD) institutions for providing various kinds of education in the field of nuclear energy. Today, it is recognized as the leading HRD center in Korea

[en] A computer simulation code is developed to examine electrorefining process for the conceptual ATW wastes treatment in Los Alamos National laboratory. A electrorefining process is modeled using diffusion layer theory and Butler-Volmer type interface reaction. In the bulk region, the concentration of fission products and actinides is assumed to be constant regardless of positions because turbulence due to stirring. Migration and diffusion is considered at the diffusion layer of molter-salt and diffusion is considered at the diffusion layer of liquid metals. Generalized Butler-Volmer model is applied at the interface between liquid metal and molten-salt. Mass conservation equation is solved by LSODI package. This paper presents the modeling and example calculation. (author)

[en] Fuel Failure Monitoring System (FFMS) detects fission gas and locates failed fuels in Liquid Metal Reactor. This system comprises three subsystems; delayed neutron monitoring, cover gas monitoring, and gas tagging. The purpose of this system is to improve the integrity and availability of the liquid metal plant. In this paper, FFMS was analyzed on detection method and compared with various existing liquid metal plants. Sampling and detecting methods were classified with specific plant types. Several technologies of them was recognized and used in most liquid metal reactors. Detection technology and analysis performance, however, must be improved because of new technology when liquid metal plant is built, but the FFMS design scheme will not be changed. Thereby this paper suggests the design to implement KALIMER(Korea Advanced LIquid MEtal Reactor) FFMS

[en] Material aging is a principle cause for the aging of engineering systems that can lead to reduction in reliability and continued safety and increase in the cost of operation and maintenance. As the nuclear power plants get older, aging becomes an issue, because aging degradation can affect the structural integrity of systems and components in the same manner. To ensure the safe operation of nuclear power plants, it is essential to assess the effects of age-related degradation of plant structures, systems, and components. In this paper, a mechanistically based probabilistic approach is reviewed as a framework for this material aging degradation of NPPs. For the first level modeling of this process, the EAC-induced failure process, is one of the main degradation processes of nickel-based alloys in the pressurized water reactor environments, has examined the effect of uncertainties in key parameters in models for EAC, fracture and inspection, based on a sensitivity study.

[en] The nuclear manpower development project has concentrated on the systemisation and specialization of education and training programs and has actively carried out diverse activities to create new nuclear courses based on the experience of the Nuclear Training and Education Center (NTC) accumulated over the past years. As the demand of education program for training nuclear manpower is increasing due to the remarkable growth of nuclear industry, NTC developed customized education programs making the most use of nuclear experiment equipment and providing practical exercise with research reactor. For improving organizational performance and the development of skilled manpower, KAERI-ACE 2.0 system offered diverse programs addressing the type of occupation and position based on individual competency. Also education on IT was carried out to improve public relations on nuclear and field trips were arranged to encourage local residents' better understanding of the nuclear industry. As a continuous effort, In 2011, NTC specially conducted a survey of employees who are attached to small and medium sized business, and analyzed the present business situations and education requirements for the development of a Pre/under job education program. Prior to this, a briefing session took place for mutual exchange of opinions of industry and academia, based on which a test operation on 'Basic Radiation Education' was carried out. This program has a significance that it was first step toward connection between the nuclear industry and academia as well as an opportunity to educate the employee involved in nuclear engineering field. In 2012, this program is planned to be expanded. With reference to the in-house training, NTC established an 'e-HRD system' providing available resources concerned with education program for cultivating talented personnel. All the education programs are based on individual competency. The e-HRD system will be test operated in 2012 and applied to the supporting of mentoring program, OJT, retaining top employees

[en] Since a vessel head penetration had been found leaking at French Bugey 3 plant is 1991, many researches have been performed upon the cracking by PWSCC in CRDM nozzle penetrations. The prediction of both initiation and propagation of nozzle cracks in CRDM must be one of most important issues in the viewpoint of maintenance, safety review and life extension of nuclear power plant. In this study, an improved probabilistic analysis method based on Weibull distribution normalized by key parameters is presented through both vessel inspection data of domestic and foreign nuclear power plants and experimental data of many laboratories, and the applicability to the prediction of crack initiation is evaluated using a specific plant operational condition. The probabilistic approach used in this study might be considered as a realistics method for the prediction of crack initiation in vessel head penetrations with variously different kinds of influencing parameters, though this approach could not make a physically accurate prediction of crack initiation

[en] The industry-university-research collaborative education is aiming at developing national nuclear human resources to satisfy with the increasing needs from the industry. For this efforts are being made to develop curricula customized to respective industry needs by improving existing ones. As the demand for training programs for the university students and domestic nuclear personnel was increasing owing to revitalization of nuclear industry, Nuclear Training Center (NTC) improved previous education programs to meet the needs. NTC has operated 2 education programs on research reactor experiments for the university students, and 18 programs on nuclear technology related experiment courses in 2010. Furthermore, the NTC developed new education programs related to 'standardized research reactor system design'. Also the request from universities for internship programs was increased by about three times in 2010 compared to those of the previous year, and this required to develop relevant curricula. In 2005, NTC developed KAERI-ACE, as a unique competency-based staff education system of Korea Atomic Energy Research Institute (KAERI). Based on the system, the NTC has performed 'systematic education'. In 2008, NTC was awarded Best HRD(Human Resource Development) in Public sector for the first time as a government-supported research institute. In 2009, the system was improved to become KAERI-ACE 2.0, based on which, in 2010, NTC improved and diversified education programs including various cyber training programs
