Secondary precipitation within the cementite phase of reactor pressure vessel steels

Autor: G.D.W. Smith, J. Zelenty, Michael P. Moody, K. Wilford, Jm M. Hyde

Publikováno v: Scripta Materialia. 115:118-122

Solute clustering is known to play a significant role in the embrittlement of reactor pressure vessel (RPV) steels. In this study, previously unobserved manganese-, nickel-, and silicon-rich precipitates in the cementite phase of a thermally aged, lo

Publikováno v: Hyde, J M, Boothby, R M, Swan, H, Riddle, N, Wilford, K, Burke, M G & Efsing, P 2018, ' A sensitivity study using maximum entropy to interpret SANS data from the Ringhals Unit 3 NPP ', Journal of Nuclear Materials, vol. 509, pp. 417-424 . https://doi.org/10.1016/j.jnucmat.2018.07.027

SANS experiments were performed on a high Ni weld surveillance sample from the Ringhals NPP and the Maximum Entropy method was applied to determine the most probable size distribution of irradiation-induced scattering features. The results were shown

Characterisation of interfacial segregation to Cu-enriched precipitates in two thermally aged reactor pressure vessel steel welds

Autor: Paul D. Styman, Nick Riddle, David Parfitt, K. Wilford, Jonathan M. Hyde, G.D.W. Smith

Publikováno v: Ultramicroscopy. 159:292-298

To understand the contribution of long term thermal ageing to Reactor Pressure Vessel (RPV) embrittlement two high Cu steel welds with different Ni contents were thermally aged for times up to 100,000 h at 330 °C and 365 °C. Microstructural charact

FP7 Project LONGLIFE: Overview of results and implications

Autor: A. Ballesteros, K. Wilford, Marta Serrano, Hieronymus Hein, Elisabeth Keim, Rachid Chaouadi, Frank Bergner, Hans-Werner Viehrig, Eberhard Altstadt

Publikováno v: Nuclear Engineering and Design 278(2014), 753-757

LONGLIFE (“Treatment of long term irradiation embrittlement effects in RPV safety assessment”) was a collaborative project of the 7th Framework Programme of EURATOM under the umbrella of NULIFE/NUGENIA, aiming at an improved understanding of irra

Uncertainties and assumptions associated with APT and SANS characterisation of irradiation damage in RPV steels

Autor: G.D.W. Smith, H. Swan, K. Wilford, M.G. Burke, Jonathan M. Hyde, Paul D. Styman

Publikováno v: Journal of Nuclear Materials. 449:308-314

Atom probe tomography (APT) and small angle neutron scattering (SANS) have been extensively used to characterise irradiation damage in reactor pressure vessel steels. There have been some notable successes, but also some difficulties reconciling the

Quantitative methods for the APT analysis of thermally aged RPV steels

Autor: George Davey Smith, Paul D. Styman, K. Wilford, Jonathan M. Hyde

Atom Probe Tomography (APT) is extensively used for the analysis of RPV steels. However, many different analysis methods and cluster search parameters are used, making comparisons between different datasets difficult. Suitable d(max) and N(min) param

Precipitation in long term thermally aged high copper, high nickel model RPV steel welds

Autor: K. Wilford, Jm M. Hyde, A. Morley, Pd D. Styman, G.D.W. Smith

Publikováno v: Progress in Nuclear Energy. 57:86-92

Copper precipitation in irradiated RPV steels is well known to have a deleterious effect on mechanical properties. In order to understand the contribution of thermal ageing to RPV embrittlement a high copper (0.44 at.%), high nickel (1.6 at.%) model
