초록
M2LFR-1000 is a medium-power modular lead-cooled fast reactor, developed by University of Scienceand Technology of China (USTC), aiming at achieving a reactor design fulfilling the Gen IV nuclear systemrequirements and meanwhile emphasizing the optimum safety and economics. In order to evaluate thesafety performance of M2LFR-1000 reactor core, three typical transients are selected from initiatingevents, which are unprotected transient overpower (UTOP), unprotected loss of offsite power(ULOHSþULOF) and increase of feedwater flowrate with primary pumps trip (IFWþPLOF). These threetransients presented and discussed in this paper are performed with the code Analysis of THermalhydraulicsof LEaks and Transients (ATHLET), which is developed by Gesellschaft für Anlagen-undReaktorsicherheit gGmbH (GRS). The results indicate that the M2LFR is safe enough under these threetransients due to the good inherent safety features of the reactor, without human intervention, thereactor will reach a new steady state under UTOP condition
