Beelman, R J

An effort to parallelize RELAP5 was undertaken in order to capitalize on recent computational hardware developments in achieving the goal of realtime RELAP5 simulation. The objective was attained on a Stardent Titan 750 vector-parallel machine as proof of concept during a small break loss-of-coolant accident simulation on a representative three loop Westinghouse engineering plant model. Technical considerations bearing on the objective of realtime RELAP5 simulation are presented. On-going developmental efforts are discussed. Applications to full-scope, full-fidelity simulation are advanced. 4 refs., 1 fig., 1 tab.
