Identification of Collectible Items in the Rancor Microworld Simulator Compared to Full-Scope Studies

Abstract

Most studies on collecting reliability data in human reliability analysis (HRA) have concentrated on research using full-scope simulators and actual operators. However, researchers have discovered challenges in collecting various items and amount of data needed to support HRA. As an opposite and complementing approach to a full-scope study, Idaho National Laboratory (INL) developed Rancor Microworld, a simplified simulator, to generate HRA data from student subjects. This paper aims to identify collectible items in Rancor Microworld versus those in full-scope simulators. In this paper, collectible items and their varying analysis levels in Rancor Microworld are identified in comparison with full-scope simulators. The appropriate method for treating the items is suggested through experiment directions for the future.
