Thermo-Mechanical Justification of the FA3 RPV Cover and Bottom Domes Under Normal and Upset, Emergency and Faulted Loading Situations

Autor: S. Vidard, S. Chapuliot, J. Hardouin, M. Sportisse

Publikováno v: Volume 6A: Materials and Fabrication.

This paper describes in a synthetic manner the work performed for the thermo-mechanical justification of the FA3 cover and bottom domes. Details on the postulated defects definition, thermo-hydraulics loading determination, thermo-mechanical model de

Tensile Characterization of Narrow Gap Bimetallic Weld Ferritic-Austenitic Steel With a New Measurement System for Tensile Testing

Autor: O. Ancelet, S. Chapuliot

Publikováno v: Volume 6B: Materials and Fabrication.

Ferritic steel 2 ¼ Cr is a candidate material for future pressure component in nuclear fields. In order to validate this choice, it is necessary, firstly to verify that it is able to withstand the planned environmental and operating conditions, and

Non-fracture prediction of a C–Mn weld joint in the brittle-to-ductile fracture transition temperature range

Autor: C. Niclaeys, S. Chapuliot, Stéphane Marie, Suzanne Degallaix, T. H. N’Guyen

Publikováno v: Engineering Fracture Mechanics. 79:149-166

This paper evaluates the brittle fracture risk for a C–Mn weld in the upper shelf of the brittle-to-ductile transition: the criterion considered is based on a critical stress σth, with the failure probability related to the volume around the crack

International audience; A Part I accompanying paper clearly showed that for a given level of strain range (Δvar epsilon), the number of cycles required to achieve crack initiation is significantly lower in biaxial thermal fatigue than in uniaxial is

Improvement of the calculation of the stress intensity factors for underclad and through-clad defects in a reactor pressure vessel subjected to a pressurised thermal shock

Autor: S. Marie, S. Chapuliot

Publikováno v: International Journal of Pressure Vessels and Piping. 85:517-531

The analysis of the stability of a defect in a cladded reactor pressure vessel (RPV) of a nuclear pressure water reactor (PWR) subjected to pressurised thermal shock (PTS) is one main elements of the general safety demonstration. Recently, CEA propos

Experimental and numerical study of crack initiation and propagation under a 3D thermal fatigue loading in a welded structure

Autor: Olivier Ancelet, S. Chapuliot, Gilbert Hénaff

Publikováno v: International Journal of Fatigue. 30:953-966

The incident which has occurred in the Civaux power plant has shown the nocivity of thermal loading, the specificity of this type of loading and the difficulty to take it into account at design level. The objective of this study is to examine the ini
