  • 저준위 방사성폐기물 안전성 평가를 위해 대상 부지를 선정하고 경계 조건을 도입하였다. 연안에 처분장이 위치할 경우를 가상하여 처분장 심도 및 단열까지의 거리등에 대한 지하수 유동 민감도를 분석하였다. 또한 처분장 진입 터널이 지하수 유동에 미치는 영향을 평가하였다. 이를 통하여 각 암반별 이동 거리 및 시간을 CONNECTFLOW를 이용해 산정하고, 그 결과들이 방사선적 안전성 종합 평가 코드인 MASCOT의 입력 자료로 활용되도록 하였다.

  • The purpose of Radioactive Waste Acceptance Criteria(WAC) is to verify a radioactive waste compliance with radioactive disposal facility requirements in order to maintain a disposal facility's performance objectives and to ensure its safety. To develop WAC which is conformable with domestic disposal site conditions, we furthermore analysed the WAC of foreign disposal sites similar to the Kyung-Ju disposal site and the characteristics of various wastes which are being generated from Korea nuclear facilities. Radioactive WAC was developed in the technical cooperation with the Korea Atomic Energy Research Institute in consideration of characteristics of the wastes which are being generated from various facilities, waste generators' opinions and other conditions. The established criteria was also discussed and verified at an advisory committee which was comprised of some experts from universities, institutes and the industry. So radioactive WAC was developed to accept all wastes which are being generated from various nuclear facilities as much as possible, ensuring the safety of a disposal facility. But this developed waste acceptance criteria is not a criteria to accept all the present wastes generated from various nuclear facilities, so waste generators must seek an alternative treatment method for wastes which were not worth disposing of, and then they must treat the wastes more to be acceptable at a disposal site. The radioactive disposal facility WAC will continuously complement certain criteria related to a disposal concentration limit for individual radionuclide in order to ensure a long-term safety.

  • There certainly exists the radioactive inventory that exceeds the waste acceptance criteria for final disposal of the low and intermediate-level radioactive waste. In this paper, current disposal status of the long-lived radioactive waste in several nations are summarized and the basic procedures for disposal approach are suggested. With this suggestion, intensive discussion and research activities can hopefully be launched to set down the possible resolutions to dispose of the long-lived radioactive waste.

  • 스웨덴의 방사성폐기물 관리 전담 기관인 SKB는 고준위 방사성폐기물의 성공적인 처분을 위해서는 기술적 연구와 함께 사회과학적 연구도 함께 수행되어야 하며, 그 비율은 50:50 정도는 되어야 한다고 말했다. 이와 관련하여 고준위 방사성폐기물과 관련된 스웨덴 SKB의 사회과학 연구 활동과 의의, 그리고 그 중요성에 대하여 알아본다.
