Beyond design-basis accidents

{
  "id": "MLC-T-NUC-000034",
  "term": "Beyond design-basis accidents",
  "field": "Nuclear energy and radiation",
  "definition": "This term is used as a technical way to discuss accident sequences that are possible but were not fully considered in the design process because they were judged to be too unlikely. (In that sense, they are considered beyond the scope of design-basis accidents that a nuclear facility must be designed and built to withstand.) As the regulatory process strives to be as thorough as possible, \"beyond design-basis\" accident sequences are analyzed to fully understand the capability of a design.",
