Design considerations for teleoperation systems operating in gas-tight argon cells
유승남,이종광,박병석,조일제,이효직 한국원자력학회 2017 Nuclear Engineering and Technology Vol.49 No.8
In the nuclear industry, mechanical engineers spend a significant portion of their time designingequipment such as manipulators, bogies, mechanical grippers, and so on. Some customized designs canbe considered as standard mechanical equipment in this area, although it is not unusual to find that anexisting design cannot simply be copied from one project to another. Varied performance requirementscan dictate that redesign, often quite extensive redesign, is required. However, if something similar hasbeen done before, engineers could use that as a starting point for the new project. In this regard, thisstudy presents several guidelines inspired by previous design knowledge for similar development cases. Moreover, this study presents more detailed suggestions such as design guidelines for an argon-basedhot cell atmosphere and design experience for a large-scale practical hot cell facility. Design considerationsand case studies dealt with in this study are dedicated to teleoperation manipulators that are usedat a large-scale argon cell facility for pyroprocess integrated inactive demonstration (PRIDE), at the KoreaAtomic Energy Research Institute. In particular, for case studies to support the suggested recommendations,a fabricated telemanipulator system for PRIDE is introduced, and several kinds of experimentalresults associated with it are presented.

본 논문에서는 한국원자력연구원에서 연구를 수행하고 있는 사용후핵연료 건식처리 공법에 활용되고 있는 원격취급 기술의 측면에서 공정 규모별 설비 스케일을 비교하고, 각 단계별 원격취급 작업과 관련한 시뮬레이션 요구항목을 도출하였다. 특히, 공학규모 설비인 ‘PRIDE(PyRoprocess Integrated inactive DEmonstration facility)’에서 활용된 시뮬레이터인 디지털 목업(Mock-up)과 공정장치 시제품을 실제로 운전 평가할 수 있는 물리적 목업의 활용사례를 제시함으로서 원격취급형 공정장치의 최종 설치 및 운전에 선행하여 이루어지는 공정장치 성능의 사전평가 프로세스 사례를 함께 제시하였다.

Background: The advanced spent fuel conditioning process facility (ACPF) of the irradiatedmaterials examination facility (IMEF) at the Korea Atomic Energy Research Institute(KAERI) has been renovated to implement a lab scale electrolytic reduction process forpyroprocessing. The interior and exterior structures of the ACPF hot cell have beenmodified under the current renovation project for the experimentation of the electrolyticreduction process using spent nuclear fuel. The most important aspect of this renovationwas the installation of the argon compartment within the hot cell. Method: For the design and system implementation of the argon compartment system, afull-scale mock-up test and a three-dimensional (3D) simulation test were conducted inadvance. The remodeling and repairing of the process cell (M8a), the maintenance cell(M8b), the isolation room, and their utilities were also planned through this simulation toaccommodate the designed argon compartment system. Results and conclusion: Based on the considered refurbishment workflow, previous equipmentin the M8 cell, including vessels and pipes, were removed and disposed of successfully after azoning smear survey and decontamination, and new equipment with advanced functionsand specifications were installed in the hot cell. Finally, the operating area and isolation roomwere also refurbished to meet the requirements of the improved hot cell facility.
