Nuclear security risks in Ukraine

Abstract

An approach to conducting a qualitative risk assessment in the field of nuclear security was developed. Nuclear security events that might, with a certain probability, take place in Ukraine were identified. Using the method of expert assessment, qualitative assessments of the probabilities of the implementation of identified events and the levels of their consequences were obtained, a matrix of consequences/probabilities, in which Fibonacci numbers were applied when setting the limit values оf risks, was built and a qualitative assessment of risks was carried out. It has been established that in the field of Ukraine's nuclear security, the risk of sabotage at nuclear power plants is the greatest.
