Arizona Public Service (APS) Company recently upgraded the Emergency Response Facility (ERF) computer at the Palo Verde Nuclear Generating Stations (PVNGS). The project was initiated to provide the ability to record and display plant data for later analysis of plant events and operational problems (one of the great oversights at nearly every nuclear plant constructed) and to resolve a commitment to correct performance problems on the display side of the system. A major forming objective for the project was to lay a foundation with ample capability and flexibility to provide solutions for future real-time data needs at the plants. The Halliburton NUS Corporation`s Idaho Center (NUS) was selected to develop the system. Because of the constant changes occurring in the computer hardware and software industry, NUS designed and implemented a distributed Open Systems solution based on the UNIX Operating System. This Open System is highly portable across a variety of computer architectures and operating systems and is based on NUS` R*TIME{reg_sign}, a mature software system successfully operating in 14 nuclear plants and over 80 fossil plants. Along with R*TIME, NUS developed two Man-Machine Interface (MMI) versions: R*TIME/WIN, a Microsoft Windows application designed for INTEL-based personal computers operating either Microsoft`s Windowsmore » 3.1 or Windows NT operating systems; and R*TIME/X, based on the standard X Window System utilizing the Motif Window Manager.« less
