A document control system (DCS), ANSIM (KAERI Advanced Nuclear Safety Information Management) was designed for the purpose of documents preparation, review, and approvement for JRTR (Jordan Research and Training Reactor) project. The ANSIM system consists of a document management, document container, project management, organization management, and EPC (Engineering, Procurement and Construction) document folder. The document container folder run after specific contents, a revision history of the design documents and drawings are issued in KAERI. The EPC document work-scope is a registry for incoming documents in ANSIM, the assignment of a manager or charger, document review, preparing and outgoing PM memorandum as attached the reviewed paper. On the other hand, KAERI is aiming another extra network server for the NRR (New Research Reactor) by the end of this year. In conclusion, it is the first, computation system of DCS that provides document form, document number, and approval line. Second, ANSIM increases the productivity of performance that can be recognized the document work-flow of oneself and all participants. Finally, a plenty of experience and knowledge of nuclear technology can be transmitted to next generation for the design, manufacturing, testing, installation, and commissioning. Though this, ANSIM is expected to allow the export of a knowledge and information system as well as a research reactor.

Human reliability analysis (HRA) is a proactive approach to model and evaluate human systematic errors, and has been extensively applied in various complicated systems. Dependence assessment among human errors plays a key role in the HRA, which relies heavily on the knowledge and experience of experts in real-world cases. Moreover, there are ofthen different types of uncertainty when experts use linguistic labels to evaluate the dependencies between human failure events. In this context, this paper aims to develop a new method based on linguistic hesitant fuzzy sets and the technique for human error rate prediction (THERP) technique to manage the dependence in HRA. This method handles the linguistic assessments given by experts according to the linguistic hesitant fuzzy sets, determines the weights of influential factors by an extended best-worst method, and confirms the degree of dependence between successive actions based on the THERP method. Finally, the effectiveness and practicality of the presented linguistic hesitant fuzzy THERP method are demonstrated through an empirical healthcare dependence analysis.

This study presents a new approach for expert opinion elicitation process to assess an uncertainty inherent in accident management. The need to work with rare event and limited data in accident management leads analysis to use expert opinions extensively. Unlike the conventional approach using point-valued probabilities, the study proposes the concept of fuzzy probability to represent expert opinion. The use of fuzzy probability has an advantage over the conventional approach when an expert's judgment is used under limited dat3 and imprecise knowledge. The study demonstrates a method of combining and propagating fuzzy probabilities. finally, the proposed methodology is applied to the evaluation of the probability of a bottom head failure for the flooded case in the Peach Bottom BWR nuclear power plant.

Background: This foundational study on educational interventions aimed to analyze the changes in awareness, knowledge, and attitudes of young learners after they received objective information on safety management. Materials and Methods: Educational sessions on nuclear power and radiation safety were delivered to 4,934 Korean elementary, middle, and high school students in two separate sessions conducted in 2016 and 2017. The effects of these interventions were subsequently analyzed. Results and Discussion: Learner attitudes toward safety were found to be the predominant variables affecting the post-intervention risk (safety) awareness of nuclear power generation. Conclusion: The safety awareness of future generations will significantly influence policy decisions on nuclear power generation. Hence, the design of educational interventions on this subject must match variables suited to learner levels.

Background: This study aims to analyze radiation safety management and regulatory perceptions, focusing on companies that must report radiation sources. The intent is to reduce the gap between regulation measures and addressing real concerns while improving practical safety management measures and regulations for all stakeholders. Materials and Methods: Radiation safety officers at a total of 244 reporting companies using radiation generators (79.8%) and sealed radioisotopes (15.1%) were surveyed using a questionnaire. Results and Discussion: The perception that regulation is stronger than the actual risk of the radiation source used was 3.47 points (out of 5 points), indicating a score above average. The most important factors and considerations were education and training (48%) as a human factor, safety devices of the radiation source (71.3%) as a hazardous material factor, the use of radiation (50.8%) as an organizational environment, and the radiation effect of nearby facilities (67.2%) as a physical environment. Radiation safety management educational experience (F= 5.030, p< 0.01), the group with high subjective knowledge (t= 6.017, p< 0.001), and the group with high objective knowledge (t= 1.989, p< 0.05) was found to be better at radiation safety management. Conclusion: It is necessary to standardize the educational experience regarding radiation safety management because each staff member has individual differences in educational experience. It is necessary to provide more information on how to solve radiation accidents via educational content. Applying radiation safety regulations based on the factors that significantly affect radiation safety management shown in this survey will help improve safety.

지식경영에 있어서 조직 구성원들 간에 지식을 공유하는 가장 기초적이면서 기틀이 되는 것은 공유할 지식을 체계적으로 관리할 수 있는 지식분류체계를 구축하는 것이다. 이에 이 연구에서는 지식경영의 도입단계에 있는 한국원자력연구소에서 조직 구성원들이 실제로 지식을 효율적으로 공유할 수 있도록 하기 위한 최적의 지식분류체계를 구축하였다. 이 연구에서는 지식경영의 본격적인 도입에 따라 한국원자력연구소에서 실제로 활용할 수 있는 전소차원의 지식분류체계를 구축하기 위해서, 기본적인 분류체계 설계원칙 아래 기존의 다양한 분류체계를 참고하여, (1) 지식분류체계 초안 작성단계, (2) 지식분류체계 수정안 작성단계, (3) 지식분류체계 검증 및 확정단계 등과 같이 3단계 과정을 거쳐 지식분류체계를 완성하였다. 완성된 지식분류체계는 기술적인 측면과 조직체계를 감안한 미래지향적인 분류체계로서 총 218항목으로서, 대분류 8항목, 중분류 43항목, 소분류 167항으로 구성되어 있다. 여기에서 설계된 지식분류체계는 한국원자력연구소에서 지식경영을 운영할 때 지식의 체계적인 관리를 통한 조직 구성원들의 지식 공유 및 활용의 가장 기초적이면서 중요한 틀로써 이용될 수 있을 것이다. 아울러 지식분류체계 자체는 물론 지식분류체계의 초안 작성에서부터 최종안을 완성하기까지의 제반 설계과정 및 방법론적인 측면은 지식경영을 도입하려는 타 연구기관이나 기업체 등에서 지식분류체계를 설계할 때 매우 유용하게 활용될 수 있을 것으로본다.

In order to develop a domestic research roadmap for severe accidents, a special committee was established by the Korean Nuclear Society. One of the subcommittees discussed the characteristics and the relevant technical issues in the stages of fission product release and physical forms of radionuclide release and transport. The group members developed a tree to identify fission product release phenomena by tracing failures of individual defense-in-depth barriers and added possible countermeasures against failure. For each elemental issue, they searched for technical problems by examining the phenomena, accident management actions, and regulatory aspects relevant to the mitigation features for containment, including mitigation strategies against containment bypass accidents. Regulatory concerns, including the source term and the acceptance criteria for radionuclide release, were also considered. They identified further research needs regarding important technical issues based on the degree of the current knowledge level in Korea and in foreign countries, looking at the significance and urgency of issues and the expected research period required to reach an advanced level of knowledge. As a result, the group identified the 12 most important and urgent issues, most of which were expected to require mid-term and long-term research periods.

새로운 천년(millenium)을 바로 앞둔 현시점의 기업 경영 패러다임으로 지식 경영(Knowledge management)의 물결이 사회 각 분야에 일고 있다. 여기서 패러다임이란 `Way of thinking about` 또는 `way of doing`이며, 새로운 천년을 맞이하는 기업과 경영자에게 생각하는 방법과 행동의 변화를 요구하고 있다. 이러한 경영 환경하에서 원자력산업 교육은 지식 창출의 원천인 사람, 즉 인적 자원(human resource)의 고가치화에 있어 그 역할의 혁신이 강조되고 있다.
