[en] The fifth three-dimensional hexagonal benchmark problem continues a series of the international benchmark problems defined during 1992-1996 in the international VVER cooperation forum AER. The initial event of the fifth AER benchmark is a symmetrical break in the middle part of the main steam header at the end of the first fuel cycle and under the hot shutdown condition with one stuck control rod group. The main difference from previous benchmark is that the system works of the primary and secondary sides are considered in this benchmark. The main aim of the benchmark is a calculation of the transient after the recriticality had achieved. The solution of the fifth three-dimensional hexagonal dynamic AER benchmark problem obtained by code package ATHLET/BIPR8KN is presented. The used reactor scheme is described including the description of the core, primary and secondary side. The amount of necessary tuning and tools of tuning to achieve a requested in the definition of the problem reference values are considered. Comparative analysis of the results obtained by using a different detalization schemes are carried out. (author)
