Abstract [eng] Recently the reactors of both units of Ignalina NPP in Lithuania are shutdown for decommissioning (in 2004 and 2009). According to the design, the spent fuel should be returned for reprocessing to Russia. However, no fuel assemblies have been taken out from the territory of the Ignalina NPP : all assemblies of spent fuel are stored in the spent fuel pools and in the dry storage facility on-site of the Ignalina NPP.Thus, the safety justification for short and intermediate term spent fuel assemblies storage in Ignalina NPP is veRY IMPORTANT. The most important barries, preventing release of radioactivity form fuel matrix to environment is the fuel rod cladding. The condition (integrity) of cladding at the end of intermediate storage of spent fuel assemblies may be evaluated by performing simulation of processes in fuel rods during whole ''life time'' of fuel assembly: beginning the first loading into reactor core and until the end of dry intermediate storage in special casks.
