摘要

针对中子注量率对核电站反应堆压力容器(RPV)钢辐照硬化脆化的影响,总结了不同铜含量RPV 钢的辐照硬化脆化的中子注量率效应.结果表明,在低铜(Cu≤0.08%)和高铜(Cu>0.08%)RPV 钢中,中子注量率对辐照硬化脆化有不同的作用结果.在中子注量率≤1×10¹² n·cm^-2·s^-1(E>1 MeV)的条件下,中子注量率对低铜RPV 钢辐照硬化脆化无明显影响,在>1×10¹²n·cm^-2·s^-1(E>1 MeV)的条件下,尚无确定结论;高铜RPV 钢辐照至富铜团簇硬化平台后,注量率对硬化脆化无影响,而达到辐照硬化平台之前,注量率对辐照硬化脆化有不同影响.

Abstract

The effect of neutron fluence rate on hardening and embrittlement of nuclear reactor pressure vessel (RPV) is summarized. It is indicated that the effect of neutron fluence rate on hardening and embrittlement has different influences on low-Cu (Cu≤0.08%) and high-Cu (Cu>0.08%) RPV steels. The irradiation hardening and embrittlement have no relationship with neutron fluence rate up to 1×10¹² n·cm^-2·s^-1 (E>1 MeV) in low-Cu RPV steel, but do not show definite connection if the fluence rate >1×10¹² n·cm^-2·s^-1 (E>1 MeV). The hardening and embrittlement have nothing to do with the fluence rate if the plateau in Cu-related hardening is reached. The behavior of Cu-containing steels is more complex at the pre-plateau fluence.
