Title: Fuel motion induced by a sharp burst TUCOP: PFR/TREAT test L07

Abstract

In the transient-undercooling-driven overpower (TUCOP) accident scenario for moderate-to-high-sodium-void-worth-LMFBR cores, some computer codes predict large reactivity increases caused by compactive in-pin fuel motion in low power subassemblies during a power burst resulting from sodium voiding in the lead fuel subassemblies. In this hypothetical scenario, the low power subassemblies are predicted to experience midplane failure with relatively cold cladding, which inhibits radial dispersal and results in a momentary accumulation of fuel around the midplane failure site. A major objective of PFR/TREAT Test L07 was to simulate such low-power-subassembly TUCOP conditions, measure the associated fuel motion and evaluate the fuel-motion predictions.
