The HEDL W-2 Sodium Loop Safety Facility (SLSF) Experiment was the first overpower transient test in the US to utilize full-length, fully-preconditioned LMFBR fuel pins. The 7-pin fuel bundle was irradiated for a total of 26 days at a nominal steady-state peak linear pin power level of 42 kW/m (12.8 kW/ft). A 5 cent/s overpower ramp was imposed following five days of continuous steady-state irradiation. Between 10 and 20 seconds into the transient, test instrumentation indicated a limited fuel pin cladding breach. Significant cladding disruption, molten fuel motion, and moderate fuel-coolant interactions occurred at 22 seconds into the transient.
