For achievement of goal, grounding on conclusions of the first stage of this work, on this stage is developed model of shutdown probabilistic safety assessment of a unit with VVER-1000/320. The results of the done work will be used by State Nuclear Regulatory Inspectorate of Ukraine as an independent estimated model for jobs that are connected to shutdown probabilistic safety assessment.
