The EBR-II Safety Research Modification (SRM) was designed to convert the EBR-II from a steady-state irradiation facility to a more versatile safety-test reactor with pulse capability. Part of this modification was to provide an upgraded shutdown system of which the ESS ia a part. The fundamentals are presented of event and fault tree analysis as applied to the ESS and establishes the system reliability based on individual component failure rates and reactor-cycle operating times. As a result of this analysis, several improvements were suggested, the methodology was established for the other shutdown systems, and the reliability of the ESS was shown to be satisfactory.
