Safety analysis results of the DBC transients performed for the ALFRED reactor

The LEADER project aims at the development to a conceptual level of a Lead Fast Reactor Industrial size plant and at a scaled demonstrator of the LFR technology - ALFRED. This paper presents the main safety transient analysis results using the system codes RELAP5, TRACE-FRED, SIM-LFR, CATHARE and SIMMER of the DBC (Design Basis Condition) transients for the ALFRED reactor. Apart from the traditional set of protected transients (PLOF, PTOP, LOOP), safety analysis was carried out for a number of carefully selected plant specific DBC transients, thus enveloping a wide spectrum of design basis conditions.
