Design and Development of Virtual Assembly Prototype System for CLEAR-I

China LEAd-based research Reactor (CLEAR-I), which is one part of Accelerator Driven subcritical System (ADS) proposed by Chinese Academy of Sciences. Assembly scenario simulation is part of the CLEAR-I R&D project, enabling their suitability for the environment or scenario key points to be verified, taking into account unexpected situations and providing technical answers. Based on virtual reality technology, a virtual assembly prototype system for CLEAR-I has been developed for training, ergonomics evaluation, safety and security purposes. Main capabilities of system include: 1) CAD-based virtual scene modeling; 2) immersive experience in virtual environment; 3) interactive virtual assembly simulation of complex components. The paper describes the system architecture, main methods and its preliminary application to CLEAR-I.
