Design basis accident analysis for the Ignitor experiment

A safety analysis study has been applied to the Ignitor machine. The main initiating events have been identified, and accident sequences have been studied. A deterministic assessment of the main accidental sequences has been performed. The consequences of the radioactive environmental releases have been assessed by means of a population dose code. This paper analyzes the deterministic consequences of two accidental sequences, serving as the “design basis accidents” because of the extent of radioactive release involved, either outside or inside the building. The two sequences with higher releases have been considered. The deterministic analysis has achieved the following results: the Ignitor machine, both during routine operation and accidental sequences, presents a negligible environmental impact and radiological risk.
