A Probabilistic Safety Assessment (PSA) was performed for the Australian Replacement Research Reactor (RRR) as a complement to its Preliminary Safety Analyses. The RRR is presently being built at Lucas Heights, Australia, and should become critical by 2005. Since this PSA was developed in parallel with the basic engineering phase of the RRR, the preliminary results were used as input to the design process, thus permitting improvements to be made to the design, and resulting in a very low residual risk.The scope for the present PSA is a Level I PSA with certain Level III considerations. The PSA includes consideration of all envisaged operation modes of the RRR, and all expected radiation sources that may exist in the plant.
