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.

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.

Fault-Tolerant Mechanism of Both Job Execution and File Transfer for Integrated Nuclear Energy Simulation

The integration of several codes to simulate physical processes or components of a nuclear energy facility facilitates large-scale, detailed simulation. However, integrated simulations require several weeks or months of CPU time. We developed a fault-tolerant method for cooperative execution of codes, which avoids unscheduled outage of computers or networks. The method deals with abnormal job terminations on supercomputers and file transfer errors. If a computer causes an unexpected outage, the method attempts to submit the simulation task to an alternative computer. The method also detects transfer errors by comparing the size of files before and after transfer. The relationship between jobs and file transfers is connected by the fault-tolerant method, which allows us to decide the execution order of codes by definition of file flow. This enables the operation on integrated simulations where codes are executed sequentially or concurrently.
