In assessing the safety of liquid metal fast breeder reactors, various extremely-low-probability hypothetical core-disruptive accidents, with postulated events that might challenge containment and lead to release of radioactive material, are considered. Test L05, conducted in Argonne National Laboratory's Transient Reactor Test Facility (TREAT) with UK Prototype Fast Reactor (PFR) fuel, simulated one such accident. L05 was an in-pile, transient-undercooling-driven overpower (TUCOP) test within the PFR/TREAT collaborative program between the USDOE and the UKAEA. Seven grid-spaced full length, bottom-plenum fuel pins containing annular pellets of mixed oxide were tested to destruction in a Mark-IIIC integral loop with a flowing sodium environment. The UK manufactured fuel was preirradiated in the PFR to an axial peak burn-up of 4.2 a/o.
