Summary

 

Overview

I am interested in the study of materials for nuclear power.  My key areas of research interest are in the use of modelling at microscales (including finite element and peridynamics), micromechanisms of fracture, corrosion and hydrogen embrittlement mechanisms and atomic scale modelling of nuclear fuel cladding material.

I am currently using the finite element method to investigate pellet-clad interactions in nuclear fuels.I also have projects in understanding hydrogen embrittlement of metals for nuclear applications, including micromechanistic studies of stress corrosion cracking of stainless steels, and delayed hydride cracking and corrosion of zirconium alloys.

Finally, I am leading a new consortium under an EPSRC grant (EP/P005101/1)studying neutron irradiation damage in nuclear reactor pressure vessel steels with the universities of Manchester, Oxford and New South Wales along with the National Nuclear Laboratory, Rolls-Royce and ANSTO as collaborators.  The irradiation and hot cell work will be carried at using the OPAL reactor facility at ANSTO.
