on the proposed 7th unit of the Kozloduy Nuclear Power Plant. It assesses whether the EIA-Report allows for making reliable conclusions about the potential trans-boundary impacts on Austria. The Austrian report considers the assumption, that the Kozloduy NPP site is flood-proof, to be well-founded and the seismic hazard at the site to be low (but points out that the seismic hazard study needs updating as it was performed 20 years ago). It also highlights a number of unsubstantiated claims and some failings in the Bulgarian EIA report. These include: shortcomings in the safety analyses of the reactors being considered, including a lack of the consideration of post-Fukushima lessons learned and, as far as applicable, the use of the concept of practical elimination (pgs 60-61); serious gaps in the assessment of the impact of external human induced events such as crashes, leaks etc. (pgs 72-73); contrary to IAEA (2002) analysis requirements, the EIA report does not contain considerations about the formation of pressure shock waves and their possible impact on buildings of the NNU due to explosions outside the perimeter of the NPP (pg 73) no comprehensible technical basis provided for an evaluation of design basis accidents and severe accidents (pg 84) only three (insufficient) “typical” dry case weather conditions were used for the calculations of the trans-boundary impacts on the Austrian territory, not worse case scenarios.
