External human induced hazards

EXTERNAL HUMAN INDUCED HAZARDS Aircraft crashes 

The potential for aircraft crashes shall be evaluated, including impacts, fire and explosions on the site, with account taken of present and future characteristics for air traffic, the locations and types of airports, and aircraft characteristics, including aircraft with special permission to fly over or close to the facility such as fire fighting aircraft and helicopters. 

Activities in the region shall be identified that involve the handling, processing, transport and storage of chemicals with a potential for causing explosions or the production of gas clouds capable of deflagration or detonation. 

The vicinity of the site shall be investigated for any facilities where inflammable, toxic, corrosive or radioactive material that could affect safety may be stored, processed, transported or otherwise handled.

EXTERNAL HUMAN INDUCED HAZARDS Aircraft crashes... 

Recommendations on design features relating to all external events, excluding earthquakes, have been incorporated into this publication, which makes reference to the Safety Guides on external human induced events, flood hazards and extreme meteorological events [2-4],... 

The external events considered in this report include both natural hazards and human induced hazards from sources external to the site or external to the safety related buildings. Explicit reference is made to the most common external event scenarios considered in the design of research reactors (earthquake, wind, precipitation (snow, rain, hail), flood, explosions and aircraft crash, external fire), for which special recommendations are provided. However, the approach to the safety evaluation discussed in the present publication can be applied to any scenario included in the facility s safety analysis report. 

The purpose of the present Safety Guide is to provide recommendations relating to the evaluation of the flood hazard for a nuclear power plant on a coastal or river site so as to enable the identification of hazardous phenomena associated with flooding events initiated by natural and human induced events external to the site.
