Characterising Irradiation Induced Mn-Ni-Si Precipitates in Low Cu Steels for Generation III Reactor Pressure Vessel Steels
This experiment will provide insight into the mechanisms and microstructural effects of Mn, Ni and Si in nuclear reactor pressure vessel steels. Analysis of irradiation induced precipitate and cluster formation using SANS will enable the deduction of the mechanisms of microstructure evolution and their contribution to radiation hardening and embrittlement. Scattering data will provide information on precipitate size and distribution information. Together with laboratory characterisation (TEM, hardness (nanoindentation)) this will contribute to existing gaps in steel property databases for reactor pressure vessel steels. This can directly applied to predicting structural integrity of reactor pressure vessels and extending their operating lifetime.
