Simulations of loss-of-flow accidents in an LMFBR with the Sodium Loop Safety Facility

1984 
The Sodium Loop Safety Facility (SLSF), a major facility in the US fast-reactor safety program, has been used to simulate an unprotected loss-of-flow accident in a sodium-cooled breeder reactor. A series of three SLSF experiments, conducted under prototypic thermal-hydraulic conditions, gives a sequential view of the fuel-bundle disruption during such an accident: the 19-pin experiment P2 ran to the point of extensive fuel motion; the 37-pin experiments P3A and P3 ran to initial fuel-pellet disruption and initial fuel motion, respectively. The experiments are summarized, and the conclusions drawn from the series are discussed.
