Abstract

This paper presents a scenario evaluation model of the AHP (Analytic Hierarchy Process) to evaluate dismantling scenarios considering quantitative and qualitative considerations. And decommissioning information producing modules which can obtain a dismantling schedule, quantify radioactive waste, visualize a radioactive inventory, estimate a decommissioning cost, and estimate a worker's exposure was developed to assess qualitatively decommissioning information. The digital mock-up (DMU) system was developed to verify dismantling processes and find error of scenarios in virtual space. It combines and manages the decommissioning information producing modules, the decommissioning DB, and the dismantling evaluation module synthetically. By using AHP model and DMU system, the thermal column in KRR-1 was evaluated on plasma arc cutting scenario and nibbler cutting scenario using the developed decommissioning DMU system.

본 논문에서는 해체 시나리오를 정량적 및 정성적 고려사항을 반영하여 평가하기 위하여 계층적분석이론(Analytic Hierarchy Process, AHP)을 이용한 평가모델을 개발하였으며 또한 해체 시나리오의 정량적인 자료산출을 위하여 해체일정, 폐기물량, 방사화 가시화, 해체비용, 작업자 피폭량 등과 같은 해체정보산출모듈을 개발하였다. 그리고 해체공정을 가상환경에서 구현하여 해체절차를 파악하기 위하여 디지털 목업(Digital Mock-Up, DMU)을 개발하였으며 DMU 시스템은 해체정보산출모듈, 해체 DB 및 해체 시나리오 평가 모듈을 통합적으로 관리하도록 개발되었다. 마지막으로 개발된 해체 DMU 시스템과 계층분석과정 모델을 연구로 1호기(Korea Research Reactor-1, KRR-1) thermal column의 플라즈마 절단 시나리오와 nibbler 절단 시나리오에 적용하여 비교 평가하였다.
