  • The significance of hydro-power plant is increasing in its public roles such as flood control and water supply as well as electric power production. Even if high level of reliability in facility operation is required, no specific reliability research has been made. This specifically stems from the lack of technology and research investments. The eventual goal of this study is to secure a methodology for reliability analysis of hydro-power plant so that an appropriate decision for operation and investment can be made. Specific effort was put to develop a reliability model for water supply system within hydro-power plant. For this study, we briefly examined the overview of the hydro-power plant including the electric power generation facility system. We then discussed the facility reliability analysis methodology for hydro-power plant. Based on rigorous examination of the water supply system and components roles, we drew major failure modes for each component and examined their effects.

  • This study had the goal of designing onboard structures for a pre-pilot mining test (PPMT), which is required for the commercialization of the deep-sea mining industry. This PPMT is planned to validate the performance of a hydraulic lifting system and verify the concept of operating through a moon-pool in the east sea, Korea. All of the onboard equipment and facility were designed by KRISO. Because the test was performed at the first development, it is difficult to determine what risk will occur in the facility. Therefore, risk-based design is required in the facility for the PPMT, which includes the facility layout, failure mode and effect analysis (FMEA), and risk reduction plan. All of the expected performances of the lifting system itself and the onboard facilities were qualitatively validated using the risk-based design.

  • The workplace noise environment is composed of three basic elements : manufacturing (in a generic sense) facilities, office areas, and the community around the facility. Work must be done by all employees , and this involves communication within a variety of locations within the facility ; areas may be extremely noisy, moderately noisy, or quiet, such as an office. At the same time, the facility should not be annoying to the community. In this paper, the workplace environmental noise of office areas in power plant are studied. Turbine generator in power plant generates the noise of 90∼95 dB(A) in the frequency range of 1 kHz, which may cause occupational hearing loss. By abatement method which are made of isolation material and distance damping effect, about 29.5 dB(A) reduction has been obtained in office areas of the Power Plant . But, the workplace environmental noise of office areas in the power plant is not suited to office's purpose.

  • A Quarantine Pest Research Facility (QPRF) had been build in Animal and Plant Quarantine Agency and designed to ensure alien pests are safety contained inside the laboratory. Functions of QPRF including insect rearing, research, and physical containment facility were verified to check suitability as a research laboratory using the beet armyworm, Spodoptera exigua. As insect rearing and laboratory facility, S. exigua completed its development for 32.2 days at 25℃. Egg hatching, pupation, and adult eclosion showed 80, 86.6, and 90%. Two pesticides, fluxametamide and hydramethylnon showed high susceptibility against S. exigua larvae by spraying and dipping methods. As physical containment facility, male adults, which were artificially released from laboratory, did not capture in delta trap installed sex pheromone lure during winter season. Based on these results, QPRF will be used for study on alien insect species.

  • Increase of consumption in limited coal reserves leads prices surging. As a result, iron works which produce products with coal are in difficulties. Accordingly, it is required a lot of research of using non-caking coal that is relatively low cost and has abundant reserves. Direct drying and indirect drying are two major methods of drying the coal. Recently, to minimize the needed calories and to save energy, using fluidbed or fluidizing method is a recent main trend of minimizing the size of the facility and maximizing energy efficiency. However there is also disadvantage such as increasing facility investment because of installing additional facilities in the latter part. In this study, we will have theoretical researches on the indirect drying method with heat exchange system which have been traditionally used. As a result it is expected to increase the efficiency of the facility operation.

  • Recently, as the number of landscaping plant nurseries have increased, environmental problems such as topographical damage due to indiscriminate changes in land use, increased non-point pollution, and increased impervious areas are also occurring. In this study, we propose eco-friendly facilities and a detailed maintenance manual that can enhance the eco-friendliness and scenic beauty of landscaping plant nurseries that are increasingly located near cities. By exploring previous reports on eco-friendly facilities and related laws, we cataloged the types of eco-friendly facilities, and by referring to examples of eco-friendly facilities introduced in overseas cases and the environmental functions of agriculture, we cataloged the types of eco-friendly facilities suitable for introduction in plant nurseries. The selected facilities are rain gardens, tree boxes, vegetated filter beds, bio-retention, infiltration trench, infiltration tanks, permeable pavements, and sand filtration systems. The maintenance tasks of eco-friendly facilities were categorized and management plans were proposed, which is expected to be utilized as a basic data to prepare eco-friendly space planning and operation management plans when creating a landscape plant nurseries in the future.

  • In korea, 500MW standard coal fired power plants were designed and operated for the initial base load, so facility stability was prioritized from facility problem to treatment, but now we needed to research for minimizing greehouse gas emissions at the operation of coal fired power plants. research on various facilities and technologies was actively conducted to reduce environment pollutants was drastically reduced, but research and attempts on coping measures in the event of a reduction facility problem were in sufficient. this study considered investigated ways to minimized pollutants by quickly responding to logic development and application of the load runback concept in case of serious problems with environmental pollutant reduction facilities such as NOx reduction selective catalytic reduction facilities, SOx reduction wet flue gas desulpherisation facilities, and TSP(Total Suspended Particles) collection low temperature electric precipitator.
