Nuclear power plants play a pivotal role in the global energy infrastructure, fulfilling a substantial share of the world's energy requirements in a sustainable way. The management of these facilities, especially the handling of spent nuclear fuel (SNF), necessitates meticulous inspections to guarantee operational safety and efficiency. However, the prevailing inspection methodologies lean heavily on human operators, which presents challenges due to the potential hazards of the SNF environment. This study introduces the design of a novel Pre-Batched Inspection Strategy (PBIS) that integrates robotic automation and image processing techniques to bolster the inspection process. This methodology deploys robotics to undertake tasks that could be perilous or time-intensive for humans, while image processing techniques are used for precise identification of SNF targets and regulating the robotic system. The implementation of PBIS holds considerable promise in minimizing inspection time and enhancing worker safety. This paper elaborates on the structure, capabilities, and application of PBIS, underlining its potential implications for the future of nuclear energy inspections.

민간시설물인 공동주택은 한 건축물 안에 다수의 인원이 각각 독립생활을 할 수 있도록 지어진 주택으로서 부실점검에 의한 건축물 안전사고 발생 시 인명피해가 제일 많이 발생할 수 있는 건축물이다. 하지만 관리주체의 안전점검에 대한 의식부족 및 최저가입찰방식에 의한 진단업체의 저가수주 등으로 인해 형식적인 점검이 이루어지고 있는 실정으로 향후 구조물의 유지관리 등 보수 보강 시 막대한 대가가 투입되고, 구조물의 안전사고 발생 시 인적피해를 유발할 가능성이 크다고 판단된다. 이에 본 논문은 효율적인 정밀점검 수행을 위한 현행 기준의 개선점을 도출하고자 광주광역시 및 전라남도 지역의 2종 시설물에 대하여 최근 3년간 실시한 정밀점검 대상건축물 66개동의 설계대가 및 실행대가현황을 조사 분석한다. 이를 통해 2차 대상건축물을 선정하고, 선정 된 공동주택 10개 단지의 정밀점검 보고서 및 정밀점검 실행대가 산정 기준을 평가하여 현행 문제점 분석을 통한 개선점을 제시하고자 한다.

River facilities and port structures require a regular inspection and diagnosis due to obsolescence. Currently, most river facilities are undergoing indirect inspection and diagnosis by divers. The underwater inspections are not feasible due to safety issues of divers and restrictions on working hours and environment. To overcome these issues, it is intended to conduct inspections of river facilities using underwater drones. In this research, an underwater ROV (Remote Operated Vehicle) has been developed, which is a kind of drone with propellers. As a key device of this research, an injection device has been attached to the underwater drone to conduct an operation test, a stable operation test of an underwater drone, and a test of attached sensors. The river facility inspection can be carried out optimally using the hovering control of the drone and injection systems. With the developed ROV system, hovering test and injection test have been performed to verify the feasibility of this development.

This paper describes the background of the electrical safety emergency dispatch system and analyzes the operational status of the system. This system is to provide the enhanced electrical safety service to general-purpose electrical equipment users. Annual average of about 6 million cases have been implemented since 2005. In order to enhance electrical safety service and more effectively prevent electrical disasters in future, institutional expansion of the electrical safety emergency dispatch system with keeping budget is necessary. If periodic inspections with a remote monitoring system is applied, the effect of electrical safety will be improved.

To find out abnormal electrical conditions, periodic inspections for residential houses are being performed every 3 years. According to data from KESCO, the number of uninspected houses is rising as the number of empty houses during normal working hours is rising by dramatic increase in the number of nuclear families and double income families. As a result, potential hazards are increased by them. In this paper, a model of a national electric safety network is presented. In the model, functions for ubiquitous environments were partially realized.

According to the Gyeonggi Provincial Office of Education's 2018 Education Statistics, there are 4,692 schools in Korea, and most of them were built before 1985 and the aging of facilities due to earthquake and external environment has reached a serious point and are vulnerable to safety. The Gyeonggi Provincial Office of Education designated 2,561 buildings with floor space of 1,000 square meters or more under the "Special Act on Safety and Maintenance of Facilities (2018.1.18. Full Revision)" and conducted regular safety inspections. The purpose of this study is to analyze the evaluation of school facilities according to the results of a regular safety inspection and to propose a maintenance plan for educational facilities for future defects according to the conditions of the facilities.

Recently, the use of ATV (All-Terrain Vehicle) has increased due to increase in leisure activities, and the awareness of safety and traffic accidents has improved, but it still insignificant compared to other transportation. Therefore, in this study, the current status and characteristics of traffic accidents related to ATVs were investigated, and actual ATV accident was analyzed. As a result, it was confirmed that the condition of the braking system directly connected to the safety of the ATV was not well maintained. For driver safety in the future, it is considered that it is necessary to strengthen safety regulations related to experience centers and rental companies handling AVTs and to conduct regular inspections in accordance with the Motor Vehicle Management Act.

In order to prevent disaster risks caused by building aging in advance, the prevailing opinion is that it is urgent to actively improve systems such as mandatory safety inspections, and to calculate risks and develop safety management systems due to building aging. The need for systematic risk management continues to be emphasized in the process of safety inspection and repair of old buildings, but the risk management and safety management techniques of each construction entity have not been established in practice. Accordingly, this study aims to analyze the vulnerability factors of aging buildings and provide basic data on the development of a risk rating calculation model for old buildings and the efficiency of safety management systems in the future.

Construction safety inspections come in a wide variety of types. The types of inspection are, 1) a self-checking and a periodical-checking by contractors, 2) a site inspection by Ministry of Land, Infrastructure and Transprt (MOLIT) or licensing organizations and 3) others. In this situation, there are needs to determine fuction of the safty inspection and roll of stakeholders for the inspection to avoid unnecessary duplication and serious omission. The result of this study indicates a guide line for improving of consturcion safety inspection systems as a fundamental research.
