Accident Types
Criticality accidents are divided into one of two categories:
- Process accidents, where controls in place to prevent any criticality are breached;
- Reactor accidents, where deliberately achieved criticality in a nuclear reactor becomes uncontrollable. Excursion types can be classified into four categories depicting the nature of the evolution over time:
- Prompt Criticality Excursion
- Transient Criticality Excursion
- Exponential Excursion
- Steady State Excursion

Famous quotes containing the words accident and/or types:
“A President Roosevelt comes only once in a century. I believe God knew and does know of the need of the world at this moment. I don’t believe President Roosevelt is an accident in time, or that it is an accident that he is President for a third time. I believe that Franklin D. Roosevelt truly is the voice of liberty in the world.”
—Lyndon Baines Johnson (1908–1973)
“As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
—Saul Bellow (b. 1915)
