Irradiation experiments of low copper A533B steels for reactor pressure vessel tested in JMTR

Technical Report:

Abstract

Irradiation embrittlement of A533B steels with low copper contents was investigated from the point of dose rate and irradiation temperature effects. Changes of neutron flux in the range from {approx}10{sup 12} to {approx}10{sup 13} n/cm{sup 2}/s (E>1 MeV) did not have a significant effect on the embrittlement. Irradiation temperature change of 1degC resulted in the transition temperature shift ({Delta}T{sub 41J}) of about 1degC and yield stress change ({Delta}{sigma}{sub y}) of about 0.8MPa. Factors that might affect the embrittlement of low copper steels are also discussed. (author).
