Analyses with the FSTATE code: fuel performance in destructive in-pile experiments
Thermal-mechanical analysis of a fuel pin is an essential part of the evaluation of fuel behavior during hypothetical accident transients. The FSTATE code has been developed to provide this required computational ability in situations lacking azimuthal symmetry about the fuel-pin axis by performing 2-dimensional thermal, mechanical, and fission gas release and redistribution computations for a wide range of possible transient conditions. In this paper recent code developments are described and application is made to in-pile experiments undertaken to study fast-reactor fuel under accident conditions. Three accident simulations, including a fast and slow ramp-rate overpower as well as a loss-of-cooling accident sequence, are used as representative examples, and the interpretation of STATE computations relative to experimental observations is made
A new non-marine Early Cretaceous gastropod species from Lightning Ridge, New South Wales
A new species of thiarid snail attributable to the extant genus Melanoides is described from the Early Cretaceous (middle-late Albian) non-marine deposits of the Griman Creek Formation at Lightning Ridge in northern New South Wales. It represents the oldest Australian record of the genus and the family. Implications for the palaeoecology and distribution of Australian Cretaceous non-marine gastropods are discussed.Robert J.
