摘要
对用于压水堆的 B_4C-Zr-2弥散体可燃毒物进行的辐照和分析表明:B_4C-Zr-2弥散体可燃毒物经(0.45-2.19)×10^(21)n/cm^2辐照后,其辐照稳定性好,芯块直径仅增加0.1-0.25%,氦气释放量小,当中子积分通量达到1.26×10^(21)n/cm^2时,其^(10)B 燃耗大于99%。
The B_4C-Zr-2 burnable poison dispersion for PWR are irradiated andanalyzed.It is shown that the material irradiation stability is good andpellet diamater only increases 0.1—0.25%after(0.45—2.19)×10^(21)n/cm^2irradiation,the helium release value is small,^(10)B burnup percentage is morethan 99% since neutron fluence is more than or is equal to 1.26×10^(21)n/cm^2。
