Industrial project supported by the Assessment Technology Group within the Nuclear Division of EDF Energy and performed at the High Temperature Centre in the Department of Mechanical Engineering. The research focus is the development of materials for future nuclear and conventional plant operating at high temperature and pressure to be built in the UK.- High temperature assessment of creep and modelling of crack initiation and growth of 316H steel. - Designed and developed improved instrumentation for condition monitoring onset of end-of-life of power generating plant by measuring crack growth and specimen deformation using ACPD technique. - High temperature digital image correlation strain measurement to assess the risk of failure of high temperature steam pipes.- Life prediction analysis of nuclear power plant components using creep and creep-fatigue fracture mechanics. Ductile and creep damage including creep crack growth was simulated by using the ductility exhaustion model.- FEA simulation of welding process used in nuclear power plant components fabrication and repairs to calculate the welding induced residual stresses.
