Availability Notice


The Human Performance Evaluation Process (HPEP) is a resource for U.S. Nuclear Regulatory Commission inspectors to use when reviewing licensee problem identification and resolution programs with regard to human performance. Part I provides a step-by-step process for reviewing licensee effectiveness in identifying, analyzing and resolving human performance problems. Part I also addresses the challenges in identifying and investigating human performance problems, describes three root cause analysis techniques, and discusses characteristics of effective corrective action plans. Part II is comprised of the HPEP Cause Tree and Modules. The Cause Tree is a screening tool for identifying the range of possible causes for a human performance problem. The Modules describe frequently identified causes for human performance problems and provide examples. Part II is intended to support the evaluation of licensee root cause analyses for human performance problems identified in Part I.
