  • KAERI has worked on the development of an advanced spent fuel conditioning process (ACP) since 1997. A hot cell facility, termed the ACPF, has also been developed. The ACPF consists of two air-sealed hot cells. The results of a safety analysis as part of the license procurement process stipulated by the Korean Government showed that the facility was designed safely. After its construction, an integrated performance test was performed. The results of this test confirmed that the facility satisfies the design requirements.

  • Since concrete is contaminated or radioactive during operation of nuclear power plants, it is the most important radioactive waste generated during the dismantling of a nuclear power plant. The amount of waste is different depending on the pollution state of each facility and the applied technology is different, so there is a big difference. We aim to reduce the amount of waste and increase the value of recyclability through technology to remove radionuclides attached to the surface. For this purpose, laser scabbling, which exfoliates the surface of concrete by irradiating a laser, and a facility system for controlling dust and dust are used in parallel. The purpose of this study is to evaluate the efficiency of laser scabbling by manufacturing simulated concrete for nuclear facilities, and to review the optimal mixing design conditions for nuclear facility structures.

  • Recently life and properties damage at Japan and China by generating earthquake. For establishing measure for earthquake in domestic, earthquake disaster measure law was enacted on March, 2008 from a natural disaster of earthquake and present the detail part and enforce the measures. This paper analyzes domestic site and problems of electrical facility earthquake measures at transformer vault which the power supply the emergence situation at generating earthquake. Also we present the domestic seismic design and construction direction from research and analysis related law and regulation for the seismic design and construction in domestic and foreign for electrical facility. Afterward we will need to study reliability inspection for electrical facility seismic design method and construction at buildings transformer vault.

  • Although the demand and necessity for the facilities of nature environmental conservation and its utilization have been increased recently, the local governments has been experiencing difficulties to launch the facilities since there are no confirmed principles or guidelines for the direction of the facility and distinctions from the ordinary parks. In this regard, the aim of this paper is to provide the overall framework for establishing the facility by equipping checklists from planning to operational stage. The stages are disengaged into 5 steps of siting feasibility, planning, preliminary environmental assessment and environmental impact assessment, design, construction, and operation. This paper also include the recommendations to vitalize the existing facilities, of which expansion of educational program development; utilization of various manpower; provision of appropriate settings; strengthened monitoring; and increased public relations. Furthermore, it is suggested to consider the strengthened local characteristics, reviewing management plan at the stage of applying a new facility establishment to the concerned authority, fostering experts, and expansion of the facilities through restoration of environmentally damaged areas for a new facility.

  • The accurate estimation of construction cost is critical for effective budgeting and financing of the project. Accurate estimates also allow for informed decisions when considering the responsiveness of bids or proposals and for a contractor to better monitor construction progress. However, current method for construction cost of the public educational facility uses a basic criteria in Korea, e.g, construction cost per unit floor area. Therefore, the purpose of this study is to examine present architectural work cost rate of elementary, middle, and high school delivered by BTL(Build-Transfer-Lease). We examined real construction cost of educational facility according to level of school, such as elementary, middle, and high school. The examination revealed that unit price of BTL educational construction cost are different to the level of school, but the composing rate of architectural work cost of the educational facility are very similar. As a result, it is recommended that future researches are initiated to create specific methods to support the accurate cost estimation of educational facility.

  • The aims of this study are proposal for architectural design guidelines and reviewing the remodeling tendencies in the campus facilities. To achieve these purposes, the architectural remodeling characteristics of 23 campus facilities have been investigated, and the technical construction methods were also analyzed for each one of these facilities. The results from this study are as follows : (1) The requests from the changes of academic plan and the degradation and obsolescence are highly occupied the causes of architectural remodeling in campus facilities. (2) In technical construction methods, the horizontal and vertical additions are effective in campus facilities remodeling. (3) According to the recent campus remodeling tendencies, the campus facility remodeling plan and schedule should be included in campus facility master plan.

  • To minimize construction of nuclear facility, it is required to reduce reinforcing bar amount and solve reinforcing bar concentration and for this, it is necessary to develop appication design technology and modular of high strength reinforcing bar. Hence, KHNP reduces excessive reinforcing bar amount which can cause possibility of poor construction of concrete through design standard development and modular of nuclear facility structure using high strength reinforcing bar to raise economics and has its purpose to maintain high-level safety and durability as they are. After reviewing the rebar drawing of the NPP structures and performing the mock-up test, the rebar modulation method in the various area of the NPP Structure has been established.

  • The recent development of PSC girder bridges are mostly dedicated for optimization of self-weight, simplification of girder section for easy construction and minimization of maintenance efforts. Moreover some of those bridges are required as a landmark facility which raises the image of locality and harmony with surroundings. An extradosed bridge is one of the best alternates which not only covers the longer span than PSC box girder and also performs the role of landmark facility with much cheaper cost than cable stayed bridge. Hyundai is carrying out the construction of unique style extradosed bridge which have central suspension system and uniform girder depth named Keong-An grand bridge on the Sungnam-Janghowon Express highway. In this paper, major process of design and construction features of Keong-An bridge is presented.
