Abstract: Disclosed is an apparatus for providing an intelligent general arrangement (GA) drawing of an atomic power plant. The apparatus comprises an intelligent GA drawing utilization unit for providing additional information on an equipment included in a particular level of a particular building of the atomic power plant, on the basis of an intelligent GA drawing in response to an user's input.

Abstract: Provided is an apparatus for quality rating-based three-dimensional modeling of nuclear power plant equipment. The apparatus performs: receiving, from a design information database, design information of atomic power plant equipment and information on multiple components constituting the atomic power plant equipment; receiving, from a quality rating database, information on the quality rating of each of the multiple components; performing, according to the design information of the nuclear power plant equipment, three-dimensional modeling of at least some of the multiple components constituting the atomic power plant equipment; and displaying the at least some three-dimensionally modeled components among the multiple components, wherein the apparatus may further display information on the quality rating corresponding to each of the multiple components.
