ADVANTAGES AND CONSTRAINTS OF SPECIFIC AUTOCAD PLANT 3D FUNCTIONS FOR DYNAMIC MANAGEMENT - CASE STUDY FOR A HEAVY WATER DETRITIATION INSTALLATION AT CERNAVODA N.P.P.

Abstract

The advantages and constraints of the specific Autocad Plant 3D functions for dynamic management - production of technological diagrams, isometrics, orthogonal views, bills of materials and piping system erection projects for the future detritiation facility at the Cernavodă Nuclear Power Plant (Cernavoda N.P.P.) are presented in a case study. In last decades 3D modelling of the plant has been increasing used in design of new projects in nuclear power plant (NPP) both in design period but also in design changes required during life time and extended life time of a plant. In the proposed case we developed a model to make an engineering design application for plant design incorporating disciplines such as piping, piping support, equipment, civil and steel structure. Using 3D Plant capabilities we can improve design process, interdisciplinary check-out as well as project execution. The project could be updated after as built revision of isometric drawings in order to obtain a training model for the system to prepare plant operators to make scheduled and unscheduled maintenance and time estimation of different maintenance procedures that could be required during plant operation in order to reduce as low as reasonable possible dose received during detritiation installation maintenance.
