Since the commercial operation of Kori unit 1 in 1978, nuclear power has provided cheap, stable and clean electricity in South-Korea. For decades, the discussion about the spent fuel management has been dominated and the government is responsible for on-going research and development (R&D) related to long-term spent nuclear fuel management. The effective management of spent fuel should be applied from the early stage of the R&D process to licensing phases with the step-by-step evaluation system. As part of follow-up efforts after the Fukushima nuclear accident, the Nuclear Promotion Commission and Nuclear Safety Commission were divided in function as an independent agency for enhancing national nuclear safety and security, which aims to protect the public and environment from undue radiological hazard. The national spent fuel project must have a vibrant program for spent fuel management. Due to the nature of these projects, the establishment of a ‘conformity assessment’ system that collects the opinions from the licensing organisations on the results of research projects from the initial R&D stage should be applied advertently in order to efficiently conduct research projects and enhance public confidence. For the government-led project for spent nuclear fuel management, the adequacy and applicability of its technology R&D as well as its sustainability that includes financial, social and environmental performance measures should be evaluated in each stage. The institutionalisation arrangement, so called ‘conformity assessment system’ for the development of a national spent nuclear fuel management plan and related technology should be developed. This study aims to propose the basic principles for the introduction of the conformity assessment system: (1) national management responsibility, (2) spent fuel management project scope, (3) its management main principles, (4) project implementation system, (5) final management project scope and securing financial resources.

The scope of this study is the construction conformity assessment system according to the new paradigm of construction management To minimize the differences between domestic and international state, construction Conformity Assessment is subdivided into system certification and product certification. For the former, WASCON(Worldwide Assessment System of Construction Quality Maturity Stage) is applied. For the latter, AQUA(Advanced Quality Assessment System) was developed and adopted to model project for demonstration. Both systems are designed to enable quantified rating, integrated into PQCS(Project Quality Certification), which is an advanced project quality certification system. The construction work observing PQCS will gain quality score on its own quality certificate(Quality mark on construction itself or facilities is also available, if needed or preferred by customers). This Quality Rating System will inspire and encourage any related parties. PQCS score would let supplier/constructor recognize how much themselves are operating effectively and efficiently, offering them the opportunity of redeeming their weaknesses.

Recently Conformity Assessment Scheme has greatly played a role in development of domestic industry. But it has limits in responding to change of environment surrounding standard. Therefore management environment has been changed, standard has been more important, and new treaties as like WTO/TBT have been appeared. In these respects this research tries to analyze the policy trends of developed countries and problems of domestic institutions. And it tries to propose seven plans to progress Conformity Assessment Scheme including improvement of domestic standard system on the basis of analytical implications.

With the chance of entering WTO, China is promoting the rebuilding of conformity assessment system in order to conform to WTO/TBT requirement and international conformity assessment system. Firstly, this research make it clear that the importance of confo

우리나라에는 1970년 이전부터 총 5,396개의 광산이 개발되었다. 하지만, 1980년대 이후 해외 광산물의 유입, 인건비가 상승하게 되면서 휴･폐광산이 증가하게 되었으며, 현재 362개의 광산만이 가행 되고 있는 실정이다. 오염방지시설이 미미한 채 방치되어 있는 휴･폐광산 부산물은 주변 토양 및 지하수를 오염시켜 광범위한 환경오염을 초래하고 있기 때문에 처리가 필요한 상황이다. 이러한 부산물을 처리하기 위해 많은 양의 토사를 사용하는 폐기물 매립지의 복토재로 사용가능 한 방법들이 연구 중에 있다. 많은 방법들 중 산업폐기물을 첨가하여 일반 토사의 사용량을 줄이는 연구가 진행되고 있다. 하지만 일반적인 산업폐기물을 이용한 복토재의 경우 높은 pH와 악취를 발생시키는 문제점이 있었다. 이에 따라 산업폐기물을 이용한 복토재의 pH와 악취를 조절할 필요가 있다고 사료된다. 이에 본 연구에서는 휴･폐광된 광산 주변의 오염토양과 MCIP 미생물과 제강슬래그를 혼합하여 중금속 용출 실험을 실시하였으며, MICP 미생물과 제강슬래그의 혼합비율을 변화하여 복토재로 적합한 조건을 알아보고자 하였다.
