Scope of this article
In listing civilian nuclear accidents, the following criteria have been followed:
 * 1) Notably severe: there must be well-attested and substantial health damage, property damage or contamination; if an International Nuclear Event Scale (INES) level is available, of at least two.
 * 2) Nuclear aspect: the damage must be related directly to nuclear operations or materials; the event should involve fissile material or a reactor, not merely (for example) having occurred at the site of a nuclear power plant.
 * 3) Primarily civilian: the nuclear operation/material must be principally for non-military purposes.
