Dynamic operations wayfinding system (DOWS) for nuclear power plants

Abstract

A novel software tool is proposed to aid reactor operators in responding to upset plant conditions. The purpose of the Dynamic Operations Wayfinding System (DOWS) is to diagnose faults, prioritize those faults, identify paths to resolve those faults, and deconflict the optimal path for the operator to follow. The objective of DOWS is to take the guesswork out of the best way to combine procedures to resolve compound faults, mitigate low threshold events, or respond to severe accidents. DOWS represents a uniquely flexible and dynamic computer-based procedure system for operators.
