  • The comparative evaluation is the most effective method for site selection because the selection of waste treatment facility is to determine the optimum site out of limited candidate sites. This study adopted the ordinal scale evaluation, one of methods of comparative evaluation. The ordinal scale evaluation aims to determine the investigating items referring to the character of sites, to determine the importance factors for investigating items, and to determine the optimum site according to the quantitative evaluation. As a result of this study, the defects of the former reports on the environmental characteristics, such as obscurity of meaning and subjective statement, were reduced by the ordinal scale evaluation which is one of the quantitative evaluation methods. This ordinal scale evaluation method has some valuable advantages, such as, to be able to consider the cost-effect efficiency, to consider the objectiveness and the clearness of the reports on the environmental characteristics. Therefore the reducement of social complications about site selection of the indisposed facilities could be expected by this study.

  • Because of the massive development of nuclear power plants in China in recent years, China is facing the challenge of radioactive waste disposal. China has established complete regulatory requirements for radioactive waste disposal, but it also has encountered problems and challenges in low-level radioactive waste disposal in terms of management, selection of disposal facility sites, and implementation of a site selection plan. Three low-level radioactive waste disposal facilities that have been operated in China are described, and their activity limits, locations, and capacities are also outlined. The connotations of "regional" and "centralized" disposal policies are discussed in light of the characteristics of the radioactive waste. The characteristics and advantages of the regional and centralized disposal policies are compared. It is concluded that the regional disposal policy adopted in 1992 can no longer meet the current disposal needs, and China should adopt a combination of the two disposal policies to solve the problem of radioactive waste disposal.

  • The stabilization and reclamation of old disposal sites is becoming more important as significant numbers of disposal sites are closed and abandoned. This technical paper covers an overview of the key issues and methodologies for stabilizing and constructing facilities on old landfills. The slide portion of this presentation also include photographs showing actual construction activities. The key issues that are prevalent in remediating and closing old landfills are : correcting the stormwater flow, leachate breakout, constructing cover caps, controlling landfill gas migration and odors, cleanup groundwater and stabilizing side slopes. Some key techniques for constructing facilities on old landfills include: use of piling, installation of active landfill gas systems, providing LFG barriers under buildings, using utilidors and flexible utility interfaces and designing for site settlement. This Paper provides proven conceptual methods for solving these problems.

  • Iksan city is planning to construct a waste incinerator on the site of about $110,000\textrm{m}^2$ in size that will be selected from a public bid(Oct.~Nov.2002)in the wake of expiration by June 2003 of use for Hamyeol fill-up ground. Science it has usually been difficult to find sites for filling-up or incinerating facilities owing to NIMBY phenomenon, it is badly requested to employ up-to-date technology for processing wastes without environmental pollution. The conflicts between the administrative authorities and community people with regard to construction of incineration facilities, fill-up ground and facilities for waste processing or recycling are not the matters of just today but are increasingly deepening and spreading countrywide. There seems to be no prospect for these conflicts to be amicably settled through dialogues. They rather become a social disease inflicting the whole country like an epidemic. It is therefore believed to be necessary to introduce measures to design and build environment-friendly facilities that may be accepted by residents as not abominable ones but be used as amusing place while they watch the daily operation of them as watchdogs. Iksan city's plan to construct environment-friendly waste incineration facilities of pyrolysis type without chimney has undergone the process of public hearings and explanatory gatherings from every class of Iksan citizens to get consensus but is still delayed due mainly to be the failure of inducing foreign investments. Pyrolysis technology has two advantages ; first, environment-friendly due to less emission of second pollutants ; second, production of by-products highly valuable as resources. It Is known that Germany has recently begun installation and operation of pyrolysis facility urban wastes, an evidence indicating that pyrolysis method will be widely applied to cope with the tightened regulation to preserve environment worldwide.

  • Although landfill has been heavily relied upon as a final hazardous waste disposal method in Korea, the legal and technical problems associated with the landfill severely hinder proper disposal of hazardous wastes. The single largest legal problem is simply that, in spite of the recent amendments, the law regulating the hazardous waste landfill is yet in its primitive stage that even the lawful landfill sites cannot be regarded safe. The technical problems include improper selection of landfill sites, poor design and construction of landfill facilities, and lack of QA/AC and post-closure cares. These technical problems stem from inexperience and lack of resources. For the reduction of the potential danger from the improper landfills of hazardous wastes, it is an immediate need to further refine the law and to resolve the technical problems.

  • 처분시설 성능을 유지하고 안전성을 확보하기 위해서는 방사성폐기물의 처분 적합성 여부를 확인하기 위한 폐기물 인수기준이 필요하다. 국내 처분장 조건에 맞는 인수기준을 개발하기 위해 경주 처분부지와 유사한 해외 처분장 인수기준과 국내에서 발생되는 방사성폐기물 특성을 분석하여 심층 검토하였다. 방사성폐기물 인수기준은 국내 전문연구기관인 한국원자력 연구원과의 기술용역을 통하여 개발되었으며 국내 폐기물 발생기관별 폐기물특성, 발생자의견 등 국내여건을 반영하여 기준이 설정되었다. 또한 설정된 기준은 학계, 연구계, 산업계로 구성된 기술자문협의체를 통해 협의되고 검증되었다. 폐기물인수기준은 국내에서 발생되는 폐기물을 가능한 수용할 수 있도록 폐기물발생기관의 의견을 수용하고 방사성폐기물 처분시설의 안전성을 확보할 수 있는 수준에서 개발되었다. 그러나 개발된 폐기물인수기준은 현재 각 발생기관에서 발생된 폐기물 전량을 처분할 수 있는 기준이 아니므로 본 폐기물인수기준에 부적합한 폐기물은 각 발생기관에서 별도의 처리방안을 강구하여 처분의뢰될 것으로 예상된다. 앞으로 방사성폐기물 처분시설의 인수기준은 장기 안전성이 보장되도록 핵종별 처분농도 제한치 등 관련기준은 지속적으로 보완해 나갈 계획이다.

  • Nagra was established in 1972 by the Swiss nuclear power plant operators and the Federal Government to implement permanent and safe disposal of all types of radioactive waste generated in Switzerland. The Swiss Nuclear Energy Act specifies that these shall be disposed of in deep geological repositories. A number of different geological formations and sites have been investigated to date and an extended database of geological characteristics as well as data and state-of-the-art methodologies required for the evaluation of the long-term safety of repository systems have been developed. The research, development, and demonstration activities are further supported by the two underground research facilities operating in Switzerland, the Grimsel Test Site and the Mont Terri Project, along with very active collaboration of Nagra with national and international partners. A new site selection process was approved by the Federal Government in 2008 and is ongoing. This process is driven by the long-term safety and feasibility of the geological repositories and is based on a step-wise decision-making approach with a strong participatory component from the affected communities and regions. In this paper a brief history and the current status of the Swiss radioactive waste management program are presented and special characteristics that may be useful beyond the Swiss program are highlighted and discussed.
