Evaluation of Irradiation Embrittlement of Reactor Pressure Vessels (RPV)


Evaluation of Irradiation Embrittlement of Reactor Pressure Vessels (RPV)

Ulbricht, A.; Strunz, P.

The A533B Cl.1-type RPV steel, designated JRQ, has been used as IAEA reference steel and shows a high sensitivity against radiation embrittlement. Specimens from this material were irradiated to three different levels of neutron fluences. Thus, the investigation allows to realize the dependence of microstructural changes on the fluence and a comparison with results on VVER-type RPV steels, which differ from the Western RPV steel design.
