Application of a New Technique for Human Event Analysis (ATHEANA) at a Pressurized-Water Reactor

摘要

Over the past several years, the U.S. Nuclear Regulatory Commission (NRC) has sponsored the development of a new method for performing human reliability analyses (HRAs). A major impetus for the program was the recognized need for a method that would not only address errors of omission (EOOs), but also errors of commission (EOCs). Although several documents have been issued describing the basis and development of the new nethod referred to as A Technique for Human Event Analysis (ATHEANA) [1, 2, and 3], two documents were drafted to initially provide the necessary documentation for applying the method: the frame-of-reference (FOR) manual, which served as the technical basis document for the method and the implementation guideline (IG), which provided step-by-step guidance for applying the method. (These two documents are now integrated into Draft NUREG-1624 [4]).
