Criticality accidents and the characteristics of prompt power excursions are discussed. Sixty accidental power excursions are reviewed.Sufficient detail is provided to enable the reader to understand the physical situation,the chemistry and material flow,and when available the administrative setting leading up to the time of the accident. Information on the power history, energy release, consequences,and causes are also included when available. For those accidents that occurred in process plants,two new sections have been included in this revision.The first is an analysis and summary of the physical and neutronic features of the chain reacting systems. The second is a compilation of observations and lessons learned. Excursions associated with large power reactors are not included in this report.
