Exclusion Criteria<br />
No<br />
Description<br />
1 A phenomenon which occurs slowly or with adequate warning with respect<br />
to the time required to take appropriate protective action.<br />
2 A phenomenon which in itself has no significant impact on the operation of<br />
a nuclear power plant and its design basis.<br />
3 An individual phenomenon which by itself has a probability of occurrence<br />
less than the 10 -5 /yr and probability of undefined release of radioactivity<br />
less than 10 -6 /yr.<br />
4 Locate the nuclear power plant sufficiently distant from or above the postulated<br />
phenomenon to mitigate its effects to an acceptable level.<br />
5 A phenomenon which is included or enveloped by design for another phenomenon.<br />
For example, storm-surge and seiche are included in flooding; or<br />
accidental small aircraft crash is included in tornado.<br />
