Full-Scale 3D Vibration Simulator for an Entire Nuclear Power Plant on the Simple Orchestration Application Framework

摘要

So far, we have developed Full-scale 3D Vibration Simulator for an Entire Nuclear Power Plant which is simulationplatform to analyze seismic response of a whole digitalized nuclear power plant. In this work, we introducedpipelined data-transfer scenario in which boundary condition data between plant's components are transferred eachtime step from large components to small components while all components simulations are run in parallel. We developedgrid-enabled application to perform this simulation more efficiently using various computing resources. Inthe development, we confronted two problems; first, pre-existing grid technology still does not sufficiently support torealize pipelined data-transfer and second, to realize long time simulation by the scenario, functionality enabling simulationrestarting to be automated is necessary. As solution of these problems, we used Simple OrchestrationApplication Framework (SOAF) which enabled pipelined data-transfer to be realized in easy and simple way and simulationrestarting to be automated. Using the SOAF, we developed grid-enabled application and succeeded seismicanalysis simulation of a test reactor in pipelined data-transfer scenario for about a week. In this paper, the details ofall of this work will be presented.
