5. SITING CONSIDERATIONS<br />

maximum historical earthquake shall be assessed. The design basis earthquakes shall be<br />

determ<strong>in</strong>ed from the seismotectonic evaluation of the region.<br />

A maximum design‐basis vibratory ground motion for earthquake shall be def<strong>in</strong>ed for<br />

protect<strong>in</strong>g the public from radiological consequences. Another vibratory ground motion is<br />

generally specified, above which the plant shall be <strong>in</strong>spected to the extent necessary.<br />

These motions should be expressed by appropriate parameters such as envelopes of<br />

frequency response spectra for various damp<strong>in</strong>g factors, duration of shak<strong>in</strong>g and time<br />

histories. As a complementary approach, probabilistic methods may be used to derive,<br />

check and compare the design ground motion.<br />

Water waves <strong>in</strong>duced by earthquakes<br />

The region shall be evaluated to determ<strong>in</strong>e the potential for tsunamis or seiches. On the<br />

basis of the available historical data for the region and by comparison with similar<br />

regions that have been well studied, the frequency of occurrence, magnitude and height of<br />

regional tsunamis and seiches shall be estimated and shall be used to determ<strong>in</strong>e design<br />

basis tsunamis or seiches, tak<strong>in</strong>g <strong>in</strong>to account amplification phenomena due to the coastal<br />

configuration at the site.<br />

Slope <strong>in</strong>stability<br />

The site and its vic<strong>in</strong>ity shall be evaluated to determ<strong>in</strong>e the potential for slope <strong>in</strong>stability<br />

(such as land and rock slides and snow avalanches).<br />

Tornadoes<br />

If tornadoes have occurred <strong>in</strong> the region, detailed historical data shall be collected and<br />

analyzed. If historical data are not sufficient, they should be supplemented with data from<br />

other regions for which tornado statistics are available and which have similar<br />

characteristics. The design basis for tornadoes shall be derived and expressed <strong>in</strong> terms<br />

such as rotational w<strong>in</strong>d speed, translational w<strong>in</strong>d speed, radius of maximum rotational
