Synopsis:

The scope of this lecture is focused on general content of safety analysis report of nuclear installation, purpose of safety analysis and its preparation according to Czech legal framework and international recommendations. Model example is represented by reactor VR-1 and its safety analysis report that will be introduced to students during lectures. Special interest is put on design basis characteristics, i.e. its description and evidence of fulfilment for geodynamics, geotechnics, seismicity and transport paths of radionuclide. In addition, students will get familiar with topic of design-basis incidents and following design extensions for reactor VR-1. Students will be acquainted with common calculation codes for safety analyses and they will also gain hands-on experience with model problems.
