  • 신뢰도 분석 방법을 이용하여 습식 사용후핵연료 중간저장시설의 냉각계통에 대한 최적 설계조건을 도출하기 위한 연구를 수행하였다. 먼저 고장수목 분석을 통한 설계 취약점을 평가하여 21개의 설계대안을 도출하였고, 최종적으로 설계대안에 대한 건설비 용, 계통신뢰도 분석 및 확률론적 안전기준을 고려한 비용효과 분석을 실시하였다. 설계 대안들 중에서 100% 루프 다중설계, 루프당 한 개의 펌프 사용, 안전등급 부여 및 주 루프에서 정화계통이 분리된 경우가 최적설계안으로 나타났다. 여기서 적용된 방법론은 유사시설의 최적설계에 유용하게 응용될 수 있을 것으로 사료된다.

  • 미곡종합처리장은 개소 당 평균 30억이 투자되는 방대한 시설로 수확된 산물상태의 벼를 수집ㆍ건조ㆍ저장ㆍ가공 및 포장공정이 일괄적으로 처리되는 농업의 첨단기술이 결집된 시설이라 할 수 있다. 미곡처리장은 약 80개의 단위기계와 100여종의 부대시설로 구성되어 있다. 미곡종합처리장은 거의 모든 과정이 중앙제어기에 의해 제어 가능하다. 그러나 미곡종합 처리장의 상온통풍건조시설은 기상조건, 투입벼의 함수율 및 반입량에 따라서 송풍기와 히터의 운전방법을 달리해야 하며, 또한 투입벼의 함수율에 따라서 벼의 퇴적고를 달리해야 하는 등 시설의 운전에 세심한 주의가 필요하다.

  • Present state of nationwide marine facilities reported to 12 regional maritime affairs and port offices of MLTM in Korea for two years 2008 and 2009 was analyzed based on region and type of facilities, and national management plan was proposed in this study. As of the end of 2009, 8 types of marine facilities were reported to Yeosu regional maritime affairs and port office, while only 3 types of facilities were reported to Pohang, Daesan and Jeju regional offices, respectively. Oil and noxious liquid substances storage facilities belonged in the type of facility which was reported to all of 12 regional offices, and ranged from 11 facilities reported to Pyeongtaek regional office to the respective 38 facilities to Yeosu and Masan regional offices. In pollutants storage facilities, 4 facilities were reported to Masan regional office, 2 facilities to Donghae and Mokpo regional offices, respectively, 1 facility to Yeosu, Gunsan and Pyeongtaek regional offices, respectively, and none of facilities to the other regional offices. Ship construction, repair and scrap facilities belonged in the type of facility which was reported to all of 12 regional offices, and 45% of the facilities were concentrated in Southeastern Sea of Korea centering around Busan and Masan. In cargo handling facilities, 3 facilities were reported to Busan and Masan regional offices, respectively, 1 facility to Daesan regional office, and none of facilities to the other regional offices. In wastes storage facilities, 5 facilities were reported to Ulsan regional office, 4 facilities to Gunsan regional office, 2 facilities to Incheon regional office, 1 facility to Yeosu regional office, and none of facilities to the other regional offices. 65% of nationwide water intake and drainage facilities were concentrated in the areas of Pohang and Mokpo, and 78% of nationwide fishing spots at play were concentrated in the area of Masan. In other marine facilities, 4 facilities were reported to Donghae regional office, 3 facilities to Masan regional office, 2 facilities to Yeosu and Pyeongtaek regional offices, respectively, 1 facility to Incheon and Ulsan regional offices, respectively, and none of facilities to the other regional offices. In integrated marine science base facilities, 3 facilities were reported to Jeju regional office, 1 facility to Yeosu, Ulsan and Gunsan regional offices, respectively, and none of facilities to the other regional offices. The management based on the circumstances of regional offices, the management based on the characteristics of the type of facilities, the amendment of the relevant rules and regulations, facility owner's full knowledge and observance of the relevant rules and regulations with regard to the relevant type of facilities, and positive management actions from national point of view were proposed for national management plans of marine facilities.

  • This study conducted a risk assessment using the HyKoRAM program created by international joint research. Risk assessment was conducted based on accident scenarios and worst-case scenarios that could occur in the facility, reflecting design specifications of major facilities and components such as compressors, storage tanks, and hydrogen pipes in the hydrogen charging station, and environmental conditions around the demonstration complex. By identifying potential risks of hydrogen charging stations, we are going to derive the worst leakage, fire, explosion, and accident scenarios that can occur in hydrogen storage tanks, treatment facilities, storage facilities, and analyze the possibility of accidents and the effects of damage on human bodies and surrounding facilities to review safety.

  • It is expected that the temporary storage facilities at the nuclear power plants will be full of the spent fuels within 10 years. Provided that a centralized interim storage facility is constructed along the coast of the Korean peninsula to solve this problem, a substantial amount of spent fuels should be transported by sea or by land every year. In this paper we developed a computer program for the analysis of transportation logistics of the spent fuels from 4 different nuclear power plant sites to the hypothetical centralized interim storage facility and the final repository. Mass balance equations were used to analyze the logistics between the nuclear power plants and the interim storage facility. To this end a computer program, CASK, was developed by using the VISUAL BASIC language. The annual transportation rates of spent fuels from the four nuclear power plant sites were determined by using the CASK program. The parameter study with the program illustrated the easiness of logistics analysis. The program could be used for the cost analysis of the spent fuel transportation as well.
