Pool Fire Testing at AEE Winfrith

The thermal assessment of transport flasks has been carried out for many years at AEE Winfrith, an establishment of the UKAEA, by theoretical modelling and by the experimental measurement of temperatures under normal transport. In 1986 our capabilities were significantly enhanced ~y the building of a Pool Fire Test Facility in which packages could be tested and fundamental research into heat transfer in pool fires carried out. This paper describes the facility and the instruments and techniques which have been developed and presents some of our findings.
