원자력시설의 콘크리트 표면제염 및 절단을 효과적으로 수행하기 위해서는 먼저 방사성물질이 제염구역의 외부로 누출되지 않도록 작업구역을 비방사성 구역과 분리하고, 국부적으로 오염된 콘크리트 표면을 제염하는 기술, 해체 절단하는 기술 및 경제적인 방법으로 방사성물질의 확산을 최소화하는 분진제거 기술 등이 개발되어야 한다. 따라서 본 논문에서는 원자력시설의 콘크리트 표면제염 및 절단시 발생되는 콘크리트 분진처리 필터시스템을 개발하기 위하여, 중량 및 고밀도 콘크리트 내부로의 세슘 및 스트론튬 핵종의 침투깊이 실험을 수행하였으며, 다중 사이클론을 이용하여 DOP 에어로졸 및 콘크리트 표면절단 장비인 scabbier에 의해 발생한 중량 및 고밀도 콘크리트 분진의 특성을 분석하고 포집효율 성능시험을 수행하였다. 또한 사이클론 성능평가 프로그램을 작성하여 사이클론의 포집효율을 예상하였으며 이를 실험값과 비교하였다.

Hereafter, the housing construction industry in a domestic country has to give more relative importance to the redevelopment and the rebuilding of existing housing rather then the housing supply methods by the development of new housing sites, and those tendencies are rapidly spreading out. Also, because apartment occupies $50\%$ over of the existing housing, its maintenance, repair, remodeling and reconstruction got to be necessary area for the slumming prevention of a residential area and the disaster prevention occurred by durability lowering of building. But, as having focused on the housing supply methods by the development of new housing sites, the domestic construction industry has relatively carelessly dealt with deconstruction areas including maintenance, remodeling, redevelopment and reconstruction of old existing housing. Therefore the process of the deconstruction is not well suited to regulations and related technology. This paper suggests the present situation of C&D production and new demolition process through comparative analysis of the present demolition works.

Radioactive waste container designs should comply with the requirements for safety (i.e., transportation, storage, disposal) and other criteria such as economics and technology. These criteria are also applicable to the future management of the large amount of LLW and VLLW to arise from decontamination and decommissioning (D&D) of nuclear power plants, which have different features compared to that of wastes from operation and maintenance (O&M). This paper proposes to develop a set of standard containers of multi-purpose usage for transportation, storage and disposal. The concepts of the containers were optimized for management of D&D wastes in consideration of national system for radioactive waste management, in particular the Gyeongju Repository and associated infrastructures. A set of prototype containers were designed and built : a soft bag for VLLW, two metallic containers for VLLW/LLW (a standard IP2 container for sea transport and ISO container for road transport). Safety analyses by simulation and tests of these designs show they are in compliance with the regulatory requirements. A further development of a container with concrete is foreseen for 2016.

This research was a technical case study for the authentic restoration of the seven-storied Simgoksa stone pagoda after disassembly and reconstruction using three-dimensional image analysis. During disassembly and reconstruction, the pagoda's properties were analyzed in terms of the overall modification and displacement of the pagoda. Distortion was minimized by ensuring structural stability during the reconstruction process. Also, the original site of the pagoda was examined in order to utilize it fully during rebuilding. Before reconstruction of the pagoda, moss and lichen on the stone surfaces were removed by scientific surface cleaning. The foundation of the pagoda was reinforced with rammed earth than was similar to the original foundation using a mixture of soil and quicklime. The results are expected to provide valuable data for the reconstruction of other stone pagodas.
