Modeling of Irradiation Embrittlement of Reactor Pressure Vessel Steels

Micromechanical testing of unirradiated and helium ion irradiated SA508 reactor pressure vessel steels: Nanoindentation vs in-situ microtensile testing

“…Matrix damage and solute clustering induced by neutron irradiation are considered to be among the main causes of embrittlement of RPV steel. Intensive research has been ongoing to investigate embrittlement mechanisms of low alloy ferritic RPV steels in the past 40 years [2][3][4][5][6][7][8]. Testing neutron irradiated materials can take a long time and is very expensive, hence alternative methods to irradiate materials have been exploited recently.…”
