Summary:

SLSF experiment P4 was designed to provide an upper-limit bound on the consequences of local faults. Three of the 37 full-length FTR-type fuel pins in the test subassembly were built with 10-cm-long, sealed fuel canisters as the center sections of the fuel regions. The fuel canisters ejected molten fuel into the bundle geometry, as planned. Each ejection was accompanied by an inlet flow deceleration and persisting flow reduction. There was no evidence of energetic fuel-coolant interactions or failure propagation through the hex duct. After about 90 s of full-power operation, scram occurred on low test subassembly flow due to gas release from fuel pins as a result of elevated inlet temperature and boiling in the blockage wake. During subsequent power operation, blockage reconfiguration and flow reduction occurred 10 minutes after 60% power was reached. The DN signal began to increase from the steady state level three minutes prior to the reconfiguration.
