... in toughness in thick section forgings and plates can be caused by carbon segregation and through thickness by the quenching process. Variation in toughness can also be caused by variation in chemical composition of the elements that enhance irradiation embrittlement, primarily copper and nickel. The geometric...

... embrittlement and increase its susceptibility to fracture. The degree of embrittlement is highly dependent on the local fluence, so it is critical to accurately characterize the spatial distribution of fluence in the RPV when performing a probabilistic fracture mechanics (PFM) analysis, which individually...

..., Reactor pressure vessel, 2 1/4Cr-I Mo steel, Embrittlement, In-service inspection. ABSTRACT The reactor pressure vessel (RPV) of the HTTR is 5.5 m in inside diameter, 13.2 m in inside height, and 122 mm and 160 mm in wall thickness of the body and the top head dome, respectively. Because the reactor inlet...

... 04 08 2008 Nuclear reactor pressure vessel steels are subjected to an irradiation-induced embrittlement in service and this may lead to a shift of the ductile-to-brittle transition temperature. The prediction of irradiation effect on toughness requires an accurate description...
