    Abstract

    The paper presents APROS BWR, Plant Analyser with 3-D core model. The model describes the Finnish Olkiluoto BWR plant owned by the TVO utility. In the APROS 3-D core model the neutronics part was described with 500 quadratic fuel assemblies. Two identical fuel assemblies were placed into each one-dimensional thermal hydraulic channel that were described either with the five- or the six-equation thermal hydraulic model. Thus, there are two independent plant analyser models with 3-D core, the five-equation plant analyser and the six-equation plant analyser. The results of the APROS 3-D core model with the alternative thermal hydraulics models are compared with the steady state results of the plant design code results. Three particular plant transients are calculated with the 3-D plant analyser using the five-equation thermal hydraulic model. The paper contains also a qualitative comparison of the transient results with the results of similar transients using 1-D core model.
