A series of transient irradiation experiments in the High Flux Reactor (HFR) study fuel pin behaviour under a variety of simulated transients in fast reactors (LMFBRs). The majority of the experiments are on mixed oxide, (UPu)O(2), fuel pins. Other LMFBR experiments carried out study the more fundamental aspects of fuel behaviour. All the experiments are performed in a predominantly thermal neutron environment in either the pool side facility of the reactor, where the transients are achieved by displacing the complete experimental rig towards the reactor core, or in-pile in the reactor core, where, if required, increases in reactor power produce the necessary conditions. The paper gives a brief summary of the HFR itself, an overview of the current LMFBR experimental programme and a description of the main characteristics of typical experimental facilities, and briefly mentions the ancillary activities connected with the experiments.
