The paper presents the baseline in the external hazards assessment for a NPP with respect to the aircraft crash. Methodology for performing assessment of the capacity of safety important facilities in case of an aircraft crash is described. The main stages of the process of assessment are identified and noted. Analyses are performed with varied parameters of the impact scenario. A demonstration of Fragility curves for the probability of exceeding given areas of perforation, is given.
