“…So far, we have developed grid-enabled application for 3D VS using client APIs (Application Program Interfaces) of grid environment of JAEA, "Atomic Energy Grid InfraStructure (AEGIS)" and have performed seismic analysis of HTTR. [6][7][8][9] By introducing the pipelined data-transfer scenario, we needed to enhance the previous grid-enabled application. In the enhancement, functionalities that should be newly added and problems involving them were as follows.…”

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

“…The grid technology is inevitable to establish the network computing infrastructure. CCSE/JAEA (Center for Computational Science and e-Systems/Japan Atomic Energy Agency) has been developing grid infrastructure for atomic energy research, AEGIS (Atomic Energy Grid Infrastructure) (2,3) . We consider that the most basic service of the network computing infrastructure is to provide tools and data sharing environment for researchers and engineers of GNEP who belong to geographically dispersed institutes and laboratories.…”

CCSE/JAEA (Center for Computational Science and e-Systems/Japan Atomic Energy Agency) integrated a prototype system of a network computing infrastructure for sharing tools and data to support the U.S. and Japan collaboration in GNEP (Global Nuclear Energy Partnership). We focused on three technical issues to apply our information process infrastructure, which are accessibility, security, and usability. In designing the prototype system, we integrated and improved both network and Ｗeb technologies. For the accessibility issue, we adopted SSL-VPN (Security Socket Layer -Virtual Private Network) technology for the access beyond firewalls. For the security issue, we developed an authentication gateway based on the PKI (Public Key Infrastructure) authentication mechanism to strengthen the security. Also, we set fine access control policy to shared tools and data and used shared key based encryption method to protect tools and data against leakage to third parties. For the usability issue, we chose Web browsers as user interface and developed Web application to provide functions to support sharing tools and data. By using WebDAV (Web-based Distributed Authoring and Versioning) function, users can manipulate shared tools and data through the Windows-like folder environment. We implemented the prototype system in Grid infrastructure for atomic energy research: AEGIS (Atomic Energy Grid Infrastructure) developed by CCSE/JAEA. The prototype system was applied for the trial use in the first period of GNEP.

Center for computational science and e-systems of Japan Atomic Energy Agency is carrying out R&D in the area of extra large-scale simulation technologies for solving nuclear plant structures in its entirety. Specifically, we focus on establishing a virtual plant vibration simulator on inter-connected supercomputers intended for seismic response analysis of a whole nuclear plant. The simulation of a whole plant is a very difficult task because an extremely large dataset must be processed. To overcome this difficulty, we have proposed and implemented a necessary simulation framework and computing platform. The computing platform enables an extra large-scale whole nuclear plant simulation to be carried out on a grid computing platform called ITBL-IS, Information Technology Based Laboratory Infrastructure and AEGIS, Atomic Energy Grid Infrastructure. The simulation framework based on the computing platform has been applied to a linear elastic analysis of the reactor pressure vessel and cooling systems of the nuclear research facility, HTTR. The simulation framework opens a possibility of new simulation technologies for building a whole virtual nuclear plant in computers for virtual experiments.
