Analysis of Credible Accidents for Argonaut Reactors

Abstract

Five areas of potential accidents have been evaluated for the Argonaut-UTR reactors. They are:• insertion of excess reactivity • catastrophic rearrangement of the core • explosive chemical reaction • graphite fire • fuel-handling accident.

“…Other potential accidents have been evaluated for the ARGONAUT reactor design, including explosive chemical reactions, graphite fires, and a fuel handling accident (FHA). However previous work has shown that these are less severe than the MHA and reactivity insertion accidents chosen for analysis here (Hawley et al, 1981;Miller et al, 1964). These two accidents were chosen for analysis because they are limiting scenarios, whose extremity bound all other accidents of consequence.…”
