ASME J of Nuclear Rad Sci 2(4), 044507 (Oct 12, 2016) (6 pages) Paper No: NERS-15-1179; doi: 10.1115/1.4032598 History: Received August 26, 2015; Accepted January 22, 2016

This paper presents a method of constructing a nuclear power plant in-service maintenance virtual simulation scene and virtual maintenance process. Taking air-baffles dismantling process of CAP1400 nuclear power plant for instance, this paper discusses ergonomics, space analysis, and time assessment based on virtual reality in the process of in-service maintenance. It demonstrates the advantage of using virtual reality technology to design and verify an in-service maintenance process of nuclear power plants compared to the conventional way.
