The paper presents the results of the OECD/NEA benchmark transient ‘Switching off one main circulation pump at nominal power’ analyzed as a boundary condition problem by the coupled system code ATHLET-BIPR-VVER. Of primary interest are the comparisons done for the local in-core parameters — assembly outlet coolant temperatures at 93 measured points and SPND powers at 7 layers of 64 fuel assemblies. Revealed are some sources of inaccuracy and methods are proposed to be decreased. An important step is done for the future performing of uncertainty and sensitivity analysis in the frame of the OECD/NEA activities.
