Post-accident heat removal in LMFBRs

Conference ·
OSTI ID:5356224
;
For safety assessments of early sodium cooled fast breeder reactors (LMFBRs), extremely unlikely events such as unprotected loss of flow and transient overpower sequences have been evaluated. The prediction of the consequences of these postulated events involves investigations of decay heat dissipation and core retention. In general, these problem areas are referred to collectively as post-accident heat removal (PAHR). This paper reviews data on heat transfer, fluid mechanics, nuclear stability and material interactions associated with PAHR. Some concepts applied in early LMFBRs for consequence mitigation are also described.
