5. SITING CONSIDERATIONS<br />

high water and high tides. The design‐basis flood shall <strong>in</strong>clude the height of the water<br />

(<strong>in</strong>clud<strong>in</strong>g waves) the duration of the flood and flow conditions.<br />

Other important natural phenomena, extreme conditions<br />

Historical data concern<strong>in</strong>g phenomena such as volcanic activity, strong, w<strong>in</strong>ds, sand<br />

storms, severe precipitation, snow, ice, hail, and subsurface freez<strong>in</strong>g of sub‐cooled water,<br />

shall be collected and evaluated. If the potential is confirmed, design‐bases for these<br />

events shall be derived.<br />

5.1.2.2. External man <strong>in</strong>duced events<br />

Criteria for design‐basis for external man‐<strong>in</strong>duced events<br />

The region shall be exam<strong>in</strong>ed for facilities and human activities that might under some<br />

conditions endanger the proposed NPP. These conditions should be classified accord<strong>in</strong>g<br />

to the severity of the effects they may have on safety. Information concern<strong>in</strong>g the<br />

frequency and severity of those important man <strong>in</strong>duced events shall be collected and<br />

analyzed for reliability, accuracy and completeness. Appropriate methodologies shall be<br />

adopted for establish<strong>in</strong>g the design‐basis man‐<strong>in</strong>duced events. Each important external<br />

man‐<strong>in</strong>duced event shall be expressed <strong>in</strong> terms that can be used as <strong>in</strong>put for deriv<strong>in</strong>g the<br />

design‐basis for these events for the NPP.<br />

Aircraft crashes<br />

If the evaluation shows that there is a potential for an aircraft crash on the site that can<br />

affect the safety of the plant, then an evaluation of the risk shall be made. If this study<br />

<strong>in</strong>dicates that the risks are unacceptable and if no practicable solutions are available, then<br />

the site shall be deemed unsuitable. The design‐basis for the event of an aircraft crash<br />

shall <strong>in</strong>clude impact, fire and explosions.<br />

Chemical explosions
