Abstract
PRORYV Project is one of the major advanced global projects in the nuclear power sector that provides for creation of the new generation nuclear power technologies based on closed nuclear fuel cycle using fast neutron reactors. On JSC “SGChE” site a Pilot Demonstration Power Complex, which consist of BREST-OD-300 (reactor with a lead coolant) and on-site plant based on closed nuclear fuel cycle is being built. On-site Plant will include the Unit for processing irradiated mixed uranium-plutonium (nitride) fuel and the Unit for fabrication the reprocessed irradiated nuclear fuel. The need to apply modern and progressive tools for process management within PRORYV Project’facilities life cycle is required by following key features: due to the large number of participants in the project and the breadth of the range of tasks to be solved, there are different information, calculation and modeling tools and approaches to their application; the high degree results’ innovation introduces considerable uncertainty in the methods of their achievement and requires a large number of R & D, the results of which constantly cause changes in the facilities’ design. While developing PRORYV Project the Information Model is created. Information Model is a continuously updated structured set of electronic data and documents on each facility and technology, which is necessary and sufficient for each stage of R & D and facilities’ life cycle (location, design, construction, commissioning, operation and decommissioning). The Information Model has several modes that are architectural, construction, functional-technological, and design. The Information Model is linked to the Project Schedule and the requirements management system. The Information Model is the basis for the creation of other systems by linking them with each other. The Integrating Project is the visualized part of the Information Model, which represents a set of electronic data and documents on PRORYV Project and contains the actual design, engineering and technological documentation on the facilities, as well as advanced data monitoring capabilities (in particular: 3D model, 4D simulation model, construction 4D-model and mathematical model). Integrating Project is required for modeling all stages of the life cycle of facilities with the purpose of timely analysis of facilities’ characteristics and technological processes. The Integrating Project is created on the basis of the Information model and is part of it. At the stage of operation and subsequent decommissioning, the Integrating project is used and supplemented by the operating organization. Due to the application of Integrating Project tools, the following works have been executed: activity on optimization and justification of the number of personnel at the Pilot Demonstration Energy Complex is organized; discrepancies in the development of electronic management procedures in the course of verification of the manuals for the operation of Fabrication Unit equipment were revealed; at an early development, conflicts in project documentation were identified. Recommendations for adjusting the technological and design documentation on BREST-OD-300 reactor unit as well as Processing and Fabrication Units were developed and issued.
