This paper introduces the policy and regulations on very low level waste (VLLW) management in China. Given the important decommissioning and site restoration program of the old facility, it is considered necessary to create a new disposal facility dedicated to VLLW. Many general design principles are in common with to the disposal facility for low and intermediate level waste (LILW), namely the isolation of the waste by means of a multibarrier system, but using bentonite and/or high density polyethylene membranes instead of the generalized use of concrete barriers. The design of the facility is consistent with the design of disposal facilities for hazardous waste. The engineering design of two VLLW disposal facilities is introduced.

본 연구에서는 한국형 중저준위 방사성폐기물 처분시설 안전성 평가를 위한 FEP 목록 도출 방법 및 선별 원칙들을 제시하였으며, 처분장에서의 핵종 이동 시나리오에 대해서는 생태계의 특성 및 공학방벽에 따라 각각의 RES (Rock Engineering System)를 구성하여 각 상황별 핵종이동을 모사 할 수 있도록 제안하였다. 또한 각 시나리오별 안전성 평가를 위하여 적용 가능한 해석 코드를 제안하였으며, 종합 성능 평가를 위한 보완점을 지적하였다. 추후 종합 성능 평가 시스템을 통해 최종적으로 도출될 안전성 평가 결과는 한국형 처분장 설계시에 활용될 수 있을 것으로 기대된다.

An integrated model for groundwater flow and radionuclide transport analyses is being developed incorporating six underground silos, an excavated damaged zone (EDZ), and fractured host rock. The model considers each silo as an engineered barrier system (EBS) consisting of a waste zone comprising waste packages and disposal container, a buffer zone, and a concrete lining zone. The EDZ is the disturbed zone adjacent to silos and construction & operation tunnels. The heterogeneity of the fractured rock is represented by a heterogeneous flow field, evaluated from discrete fractures in the fractured host rock. Radionuclide migration through the EBS in silos and the fractured host rock is simulated on the established heterogeneous flow field. The current model enables the optimization of silo design and the quantification of the safety margin in terms of radionuclide release.
