壓力容器是壓水堆核電站全壽期不可更換的關鍵部件,是核電站安全與壽命的決定因素之一。在長期服役過程中,引起壓力容器性能下降的最主要因素是長時間大劑量高能量中子的輻照。輻照將引起壓力容器材料韌性降低、脆性升高,從而增加壓力容器脆性斷裂的潛在危險。因此,壓力容器材料抗輻照脆化能力一直是該領域國內外關注的焦點之一。文章針對國產壓力容器材料,開展了一定劑量水平(約3×10 19 n/cm 2,E≥1 MeV)的研究堆加速輻照考驗,進行了輻照后材料力學性能測試分析,包括沖擊性能,動態斷裂韌性,以及疲勞性能。同時,將輻照后性能測試結果與輻照前進行對比,分析評價了國產壓力容器材料的抗輻照性能。
- Abstract:
-
Pressure vessel is the critical and unchangeable component of the PWR during its service lifetime, which determines the lifetime of nuclear power plant. The property decline of pressure vessel is mainly caused by large dose and high energy neutron irradiation during the long term service. Irradiation can reduce the toughness and increase the brittleness of the pressure vessel materials, thus raising the potential risk of brittle fracture. So irradiation embrittlement resistance of pressure
