  • 노후 원전 해체의 경우 부지 특성 및 최종 상태 조사 보고서에 해당 부지내 잔존가능성이 있는 방사성 핵종 정보에 대한 내용을 포함하여야 한다. 미국 NRC의 경우 이에 해당하는 해체기술관련문서(DTBD)를 부지 특성 조사시에 부지이력조사(HSA)와 같이 사업자 측이 제출하도록 규제하고 있다. 또한 해체기술관련문서는 방사선학적 부지 조사와 해체완료계획서에 포함되어야 하는 내용으로써 부지 규제 해제와 재이용에 관해서 중요한 자료를 제공한다. 이 논문은 부지 별 잠재적 핵종에 대해 미국 원전의 해체 사례중 부지 특성 및 최종 상태조사 과정에서 결정하는 방법론을 분석하고 2017년 고리 1호기의 영구 운전정지 후 이루어질 해체 과정에 필수적인 규제 지침과 기술적 근거 수립에 도움이 되고자 한다.

  • As one of the conservation strategies, the city of Jeonju established regulations to conserve and revitalize the Hanok village as an attractive tour site. Some of old traditional houses were renovated into traditional inns. A couple of traditional houses were additionally built for lodging houses. The need for urban rehabilitation and adaptive re-use has been growing in Jeonju province. The purpose of this study was to examine how the traditional houses were converted into lodging places balancing the conflict issues such as preserving the unique characteristics of Hanok and updating functional requirement of modern lodging in terms of sustainable reuse and development. For this study, site visits and intensive interview with the owners of the seven traditional lodges were conducted. There was lack of guidelines and strategies renovation or rehabilitation of Hanok as lodging facility for sustainable use and revitalization of city. For the seven traditional Hanok inns, layout of rooms characterized as separate and disconnected, while traditional houses were open, flexible and connected regarding room arrangement. In addition, for sustainable development, the living environment of the community should be secured and align with developing strategies of the area.

  • We examined three nature restoration projects in urban areas of Japan, China, and Korea. A prefectural park(29ha) has been under construction since 2005 on an abandoned industrial site in the southern part of Amagasaki City, Hyogo Prefecture, central Japan. Shanghai Central Park(28ha) was redeveloped in 2002 on a site that was formerly the old downtown in central Shanghai. Seoul Forest Park was developed as a large urban park(116ba) in 2005 in Seoul. All three parks were developed as urban parks by local governments. Citizen involvement is common to all three examples. One of main purposes of the Hyogo prefectural park and the Seoul Forest Park was the reuse of unused or abandoned areas. One goal in Hyogo, Shanghai, and Seoul was to restore the urban ecosystem and preserve the environment. We discussed the meaning of nature restoration in urban areas.

  • In many countries a considerable amount of demolition wastes is generated and wastes concrete constitutes a significant proportion of the construction waste. Therefore, the necessity for the use of recycled aggregate in concrete arise and the reuse of a waste concrete may solve the problems of environmental pollution and shortage of natural aggregate. According to this study is to examine the possibility of site adoption microwave-use early strength estimation method. Based on the existed study related the plain concrete, the interrelation between recycled aggregate concrte and microwave-use early strength estimation method is required.

  • Waste lime used in this study is producted as a by-product in the manufacturing process of making $Na_2CO_3$ from local chemical factory in Incheon. Currently about 320 millon tons of waste lime are accumulated and annually 100,000 tons are producted. Reuse of waste lime mixed with soil for banking and backfill materia in civil works was analysed in this study. This study was Carried out to investigate the geotechnical and environmental characteristics on field application. Field investigations were conducted on the road construction site in Incheon. This study presents the results of the engineering characteristics in field test and the leaching characteristic of waste lime in laboratory column tests. Countermeasure for reduction of environmental effects was suggested from the test results.

  • The containment building Kori Unit 1 may require sequential steps for full decommissioning. This study assumes that the containment building is to be used as an auxiliary building that handles nuclear power systems and materials during decommissioning before conversion into a greenfield. Through the derivation of guidelines and dose evaluation, it was confirmed whether the radiation workers were satisfied with the ALARA decision. The specific modeling of the external radiation exposure was performed based on the facility investigation procedures. The external radiation specific derived concentration guideline levels (DCGLs) for radiation workers in containment building were obtained using the RESRAD-BUILD code and were applied to the VISIPLAN 3D ALARA Planning Tool code to calculate the working dose and check worker safety. The derivation of site-specific and realistic DCGLs and dose evaluation via 3D modeling can contribute to the scenario development for the decommission and remediation of containment building.

  • 세계적으로 폐기물의 발생량이 급증하여 매립지의 숫자가 급증하고 있으나 사용이 완료된 매립지의 처리에 많은 어려움이 있다. 특히, 도시 폐기물 매립지는 인구밀집 지역과의 근접성, 부지개발에 따른 경제적 가치의 급등 등의 이유로 활용 가능한 새로운 건설부지로서 많은 관심이 집중되고 있다. 그러나, 폐기물 매립지반 위에 구조물을 축조할 경우, 특별한 안정처리 및 보강처리를 하지 않은 경우, 지반침하, 구조물에 대한 지지력 확보 등에 문제점이 발생될 수 있다. 따라서, 본 연구에서는 폐기물 매립지반위에 구조물을 축조할 경우, 지오그리드 및 지오셀의 보강 효과를 규명하고자 반복평판재하시험을 수행하여 주요 영향인자인 지지력증가비, 지반계수, 스프링상수, 탄성회복율 등을 평가하였다.
