  • We confirmed that the dismantling of two research reactors with thermal power of $2MW_{th}$ and $100kW_{th}$, respectively, reveals no significant difference between the radiation levels of the research reactor site and the surrounding environment far away from it, from the radiation level aspect. Radiation dose and radioactivity were measured at monitoring points around the research reactor site of the Korea Atomic Energy Research Institute (KAERI) in Seoul and comparison points 0.5 km to 3.3 km from the site. To grasp trends in the radiation levels during dismantling from the end of 2002 to the end of 2007, the gamma radiation dose rate, the accumulated dose, and the radioactivity of the strontium, tritium, and gamma isotopes were statistically treated and estimated. The averages of these items between the two groups, the research reactor site and comparison points, were assessed by applying a T-test with a significance level of 0.05. P-values found by using the T-test were from 0.12 to 0.83 where the values were much higher than the significance level. As a result, no difference was observed between the radiation levels at the research reactor site and at the comparison points by this T-test. This study showed that dismantling activity of the Korea Research Reactor of the Seoul site did not expose the public or the environment to harmful levels of radiation.

  • The objective of this study was to decide the designing factor for remediaton of the contaminated site. The soil and ground-water samples were analyzed and hydro- geological characteristics was assayed for the survey of pollution level. Also air-permeability test and MPN(most probable number) test were conducted for selecting the designing factor. The contaminants were mainly found in north-west part of the site and were expected to move toward the south. Ex-situ technology was expected more useful than in-situ one with the results of air-permeability test saying that air permeability was relatively low. Additional microbes were expected for remediation efficiency because residual microbes were loosely populated. The choosing of the designing factor was requisite for remediation of contaminated site.

  • Since mountainous area has access restrictions for field work, assessors need to establish a conceptual model of the contamination prior to the field investigation. In this study we established a conceptual model of the contamination based on site inspection and geological survey, followed by the field investigation for the petroleum spill site. In the conceptual model, we estimated that tile contamination should have spread by groundwater and topographical characteristics within the top soil layer. The spread of contamination through rock was not considered in the conceptual model due to impermeable characteristics of metasyenite. The contaminated environmental media of the petroleum spill site include soil and groundwater. According to the analysis result of the contamination, the volume of contaminated soil is estimated approximately 4, 150 cubic meters (7, 055 ton) with most contaminants existing along the groundwater flow within top soil layer.

  • The main purpose of this paper is to provide useful infonnation for residential site design in Korea by analyzing Japanese case. The important characteristics of Japanese design techniques are follows. First, the characteristics of residential site development can be expressed as "eco-friendly" and "public order". The patterns of spatial use also focuses on living environment improvement. Second, variety replaces unity in internal mobility plans. For example the width of street, size of park are not same in a site boundary. Third, to avoid street parking and commodity exhibition, commercial buildings are set-back and public parking lot is constructed. Fourth, fences of private house are made of trees rather than bricks. It connects green environment between internal and external space of houses.nal space of houses.

  • In Korea, military authorities have neglected to consider impacts of military projects on local communities and natural environment. Moreover, local communities have had difficulties in dealing with the Ministry of National Defense (MND), which was stubborn enough not to implement environmental assessment on their projects. In this situation, recent case, "EIA of Baekgol Division's Howitzer Fire Training Site" in the Supreme Court-in which judges upheld the Higher Court's decision that the division violated the Environmental Impact Assessment law by ignoring to implement EIA-reveals that military projects can no longer forgo environmental assessment. The decision has serious ramifications on the future of Environmental Impact Assessment in military-led projects. This paper examines the proper scope of EIA in military-led projects and, more specifically, fire training site and searches for how to improve it through 'probable error,' a military training method that is applied to real 'howitzer' fire training. Probable error of the artillery field manual is nothing more than an error that exceeded as often as it is not exceeded and its scientific method was demonstrated through real fire tests in the US. Army. If it is applied to improve assessment methods about the proper scope of EIA in military 'howitzer' fire training site, 'probable error' will improve effect prediction, mitigation and reliability.

  • For the safe management of nuclear facilities, including a radioactive waste repository, data about the facility site and the surrounding environment must be collected and managed systematically. This is particularly true for a radwaste repository, which has to be institutionally controlled for a long period after closure. The objectives of this study are (1) to establish a systematical management plan for information about a radwaste repository site and its environment, and (2) to design a database management program for this information, based on the Relative Database Management System (RDBMS). The spatial data are designed by the geodatabase, which is a new object, based on the RDBMS, to manage spatial information related to the database. To meet this requirement, a new program called 'Site Information and Total Environmental data management System (SITES)' is being developed. The scope that produced from the first step of the present study for development of the SITES is introduced. The database is designed to combine spatial and attribute data, and is designed for the establishment of the Geographic Information System (GIS). The hardware and software systems are designed with consideration given to the total data management of the items within the radioactive environment.
