Accident Delineation and Evaluation of the High-Temperature Gas-Cooled Reactor System Concepts

摘要

A methodology of accident delineation and analysis is developed for application to an evaluation of the conceptual design of a high-temperature gas-cooled reactor (HTGR). The conceptual design of the 3000-MW(t) HTGR is studied and probabilities of possible accident sequences are provided. Latent hazard indices are developed for the accident sequences to identify quantitatively the sequences having the greatest potential impact on the public safety.
