"Radiation impact on robot-relevant polymers for high gamma environments"
Polymers offer a number of properties of interest in robotics design, from the well established such as low weight, electrical and thermal insulation, to the more novel, where their visco-elasticity is of great benefit in designing vine robots and flexible sensors. The more dangerous the environment, for example in cases where high radiation is pre…

"Investigating the thermal and irradiation stability of chemical vapor deposited erbium oxide tritium barrier coatings for Li breeder blanket applications"
Two-micron thick erbium oxide tritium barrier coatings have been prepared by aerosol injection chemical vapor deposition and subsequently irradiated with 33 MeV Au 6+ ions at fluences up to 2.1×10 15 Au/m 2 at 550 o C. Scanning electron microscopy, X-ray diffraction and transmission electron microscopy were used to investigate the coating surf…

"The response of silicon carbide composites to He ion implantation and ramifications for use as a fusion reactor structural material"
Silicon carbide fibre–reinforced silicon carbide matrix (SiCf/SiC) composites are desirable in structural nuclear applications due to their low density, high temperature strength and tolerance to energetic radiation. We have subjected two industrial grades of SiCf/SiC to high energy He²⁺ ion irradiation, up to 10,000 a…

"Dislocation density transients and saturation in irradiated zirconium"
Zirconium alloys are widely used as the fuel cladding material in pressurised water reactors where a significant population of defects and dislocations is produced by exposure to neutrons. We present and interpret synchrotron microbeam X-ray diffraction measurements of proton- irradiated Zircaloy-4, where we identify a transient peak and the sub…

During operation, structural components made of zirconium alloys are subject to neutron irradiation, which leads to the displacement of zirconium atoms from their lattice sites, the production of self-interstitials and vacancies, and eventually dislocation loops. This process can lead to deleterious effects such as irradiation growth, creep and …

"CHARACTERISATION OF HYDRIDE PRECIPITATION AND REORIENTATION IN ZIRCONIUM ALLOYS AT DIFFERENT METALLURGICAL STATES"
Hydride precipitation and reorientation has the potential to embrittle zirconium alloys. This study aims to better understand the influence of the Zr microstructure on hydride precipitation and reorientation. Specifically, the crystallography, phase stability and morphology of hydride precipitation was correlated to microstructural variations due t…
