OSTI ID:6020034
Among the low probability LMFBR accident scenarios addressed by the collaborative US/UK transient testing program is the slow transient overpower ramp resulting from the hypothetical event of a control rod runaway with failure to trip. This has been simulated in US's TREAT facility with three tests on irradiated driver fuel from the UK's Prototype Fast Reactor. Tests C04 and C05 were single pin experiments designed as a pair to study the effect of burnup on the time, location, and mechanisms of cladding failure and initial fuel escape. They were conducted on individual fuel pins of different burnup and power history; the C04 fuel had an axial peak burnup of approx. 4% while C05 fuel had reached a maximum burnup close to 9%. Test L03, reported in detail previously, studied post-failure fuel dispersal in a bundle of seven pins like the C04 fuel.
