(p. 97) Perrow on Nuclear Power Let's get one thing out of the way immediately: Normal Accidents is an anti-nuke screed. The Three Mile Island accident, for example, was caused largely by the complex interaction of the plant's instrumentation, its human operators and a redundant failure-handling sub-system: . Explains a number of factors involved including the type of accident, warnings, design and equipment failure, operator error, and negative synergy. Perrow identifies three conditions that make a system likely to be susceptible to Normal Accidents. Perrow's normal accident theory suggests that some major accidents are inevitable for technological reasons. While Perrow shows an amazing depth of understanding about what is needed for a major accident, his application of NAT (Normal Accident Theory) on nuclear energy production facilities has not proven to be effective. "Normal" accidents, or system accidents, are so-called by Perrow because such accidents are inevitable in extremely complex systems. Aircraft and Airways 123 6.

Accident Models Study 3.1 Introduction of Accident Models Normal Accident Theory Charles Perrow termed the system accidents as "normal accident". The inspiration for Perrow's books was the 1979 Three Mile Island accident, where a nuclear accident resulted from an unanticipated interaction of multiple failures in a complex system. Three Mile Island exemplifies the features of a normal accident: a small local problem and incorrect mental models that linked actions with defects, resulting in a rapidly-emerging crisis that created considerable damage and nearly produced a disastrous off-site release of radiation. Earthbound Systems: Dams, Quakes, Mines, and Lakes 232 8. There were no deaths or injuries to plant workers or members of the nearby community which can be attributed to the accident. My initial impression was that it was the usual diatribe against nuclear power - we can't control it, yada, we're all gonna die, yadayada, we'll be radioactive for centuries . The accident at Three Mile Island displayed the four characteristics of normal accidents: warning signals, equipment and design failures, operator errors, and unanticipated events. Inspired by the 1979 near-miss at Three Mile Island, Perrow began studying high-risk systems. . Given the characteristic of the system involved, multiple failures which interact with each other will occur, despite efforts to avoid them.

In doing so he established what he called Normal Accident Theory: a situation where the systems involved were so complex and tightly coupled that an accident was, perhaps, the inevitable outcome. 101: . $21.95. He prepared a paper for the President's Commission on the Accident at Three Mile Island on the organizational aspects of the accident. I have simplified the technical details a great deal and have not tried to define all of the terms. A normal accident is where everyone tries very hard to play safe, but unexpected interaction of two or more failures (because of interactive complexity), causes a cascade of failures (because of tight coupling). An alternative approach explains major accidents as resulting from management failures, particularly in relation to the communication of information. 566 ratings59 reviews.
