방사성폐기물용기의 설계는 용도 (운반, 저장, 처분)의 안전요건에 부합돼야 할 뿐 아니라 경제성과 기술적 기준도 만족해야 한다. 이러한 기준은 장차 원전해체로부터 발생할 다량의 저준위/극저준위 해체폐기물의 관리에도 해당된다. 해체폐기물의 특성은 원전운영에서 발생하는 방사성폐기물과는 매우 다르므로 적합한 용기의 개발이 요구된다. 이 논문은 다목적용도의 표준용기 개발을 제시한다. 이 개념은 경주처분장과 같은 국가 인프라를 고려한 원전해체폐기물의 관리를 최적화하기 위한 용기이다. 이 연구는 일련의 시제품을 설계 또는 제작한 것이다 : 극저준위용 소프트백, 저준위용 금속용기 (해상운반용 표준 IP2 용기 및 도로운반용 ISO 용기), 이들 용기 설계의 안전성 분석을 위한 시뮬레이션 및 시험결과는 규제요건에 잘 부합되는 것으로 나타났다. 콘크리트 용기의 후속개발은 2016년에 수행예정이다.

Radioactive waste container designs should comply with the requirements for safety (i.e., transportation, storage, disposal) and other criteria such as economics and technology. These criteria are also applicable to the future management of the large amount of LLW and VLLW to arise from decontamination and decommissioning (D&D) of nuclear power plants, which have different features compared to that of wastes from operation and maintenance (O&M). This paper proposes to develop a set of standard containers of multi-purpose usage for transportation, storage and disposal. The concepts of the containers were optimized for management of D&D wastes in consideration of national system for radioactive waste management, in particular the Gyeongju Repository and associated infrastructures. A set of prototype containers were designed and built : a soft bag for VLLW, two metallic containers for VLLW/LLW (a standard IP2 container for sea transport and ISO container for road transport). Safety analyses by simulation and tests of these designs show they are in compliance with the regulatory requirements. A further development of a container with concrete is foreseen for 2016.

문제 정의
This paper gave the results of the second year of R&D project, as conducted by KONES Corporation, for development of containers for D&D waste management.
제안 방법
One of the key strategy would be the consideration for the large amount of VLLW arising from D&D, with little hazard, compared to O&M wastes.
대상 데이터
The body and cover of the IP2 and ISO containers are made of carbon steel (SS 400). The container body is structurally reinforced by supportive frame (SPSR 400) and the cover to be bolted on the body is lined on the corners with bumper material of rubber (EPPM).

The dimensions of the soft bag developed are 1,000×1,000×1,000 in mm and the weight is 1,200 kg (with content). The container is made of synthetic fiber with triple barriers and fixed with belts around the 4 faces and a cover with a couple of zippers (Fig. 3).
이론/모형
The analyses were conducted by finite element method (FEM) by use of ABAQUS 6.10. A friction coefficient of 0.
후속연구
It is based on the scenario that this kind of D&D waste package would be disposed of in the LLW vault being planned, or in a new VLLW repository to be developed.
