Southern California Edison (SCE) performed an individual plant examination (IPE) for San Onofre nuclear generating station (SONGS) units 2 and 3 to satisfy the requirements of the US Nuclear Regulatory Commission's Generic Letter 88-20. According to the IPE guidelines the examination includes a human reliability assessment (HRA) to assess the operators' role in accident or transient evolutions. The field of HRA began in earnest in the early 1970's. The goal of HRA, established during the Reactor Safety Study, was to identify and quantify the reliability of operator actions modeled in system fault trees and accident sequences. Insights from HRAs point to steps that can be taken to reduce the likelihood of error in important accident sequences. The performance of HRA is not an exact science, and different methodologies are available. The SCE Nuclear Safety Group initiated work in 1985 to develop a living risk model of the plants. This work was limited in scope but provided a basis for the current IPE required assessments.
