A human factors engineering-based verification of standing consoles design for SMR control rooms

Abstract

In the context of emerging nuclear power programs, small modular reactor (SMR) control rooms must address both international safety standards and local ergonomic requirements. This study presents a verification-based evaluation of two standing operator console designs for the PeLUIt-40 (Indonesian SMR) main control room, adapted to the anthropometric data of Indonesian workers. The verification process was guided by ergonomic principles and key criteria outlined in NUREG-0700 and relevant national regulations. Using task-based usability tests and post-task questionnaires involving licensed Indonesian operators with substantial practical experience and an iPWR simulator, the consoles were assessed in terms of reachability, comfort, fatigue potential, and display visibility. Results demonstrate that a locally adapted console design improves operator posture, reduces wrist fatigue, and enhances accessibility without compromising operational task performance. The findings contribute to the early-stage verification of control room design and support subsequent validation phases as prescribed in NUREG-0711. This study provides practical insights for nuclear developers in emerging countries aiming to integrate human factors and accommodate operator diversity in the design of SMR control rooms. By embedding ergonomic principles into the conceptual design process, nuclear programs can enhance operator performance, minimize post-deployment modifications, and strengthen safety in complex system environments.
