Historically, the productivity of a numerical reactor safety analyst has been hampered by several factors: poor mainframe computer turnaround for problem setup, checkout, and initialization; limited mainframe CPU allocation, accessibility and availability for transient advancement; lost or delayed output; and difficulty assimilating numerical results. Clearly, an economical engineering workstation capable of running RELAP5 interactively, and of simultaneously displaying the results in a coherent graphic fashion as they are produced, would alleviate many of these concerns. The RELAP5 desktop analyzer (RDA) is such a workstation. Although not yet capable of real-time simulation, the RDA will nevertheless reduce analysis costs and enhance analyst productivity since analysis cannot be done in real time anyway. The RDA is a microcomputer-based reactor transient simulation, visualization, and analysis tool developed at the Idaho National Engineering Laboratory (INEL) to assist an analyst in simulating and evaluating the transient behavior of nuclear power plants. The RDA integrates RELAP5 advanced best-estimate engineering simulation capabilities with on-line computer graphics routines allowing interactive reactor plant transient simulation and on-line analysis of results, or replay of past simulations, by means of graphic displays.
