放射性废物

There are 8.6%~10.91% foreign matter in the sphenes, in which radioactive elements of strontium, cesium and uranium range from 4.26% to 4.58%. The change of structural cell parameters of sphenes is still very little,Δa=-0.0009 nm~0.0041 nm,Δb=0.0018 nm~0.0004 nm,Δc=0.0002 nm~0.0048 nm,Δβ=-0.10°~0.09° with high crystallinity of 99.27%~96.46%. Though, the age of sphene from the Fenghuang Mountain is about 1000 Ma, and experienced 775 Ma~1758 Ma geological evolvement and alpha decay, its crystallinity only decreased 3%, and its crystal shape and structure are still fine, indicating that sphene is of good ability to solidify radioactive elements. Therefore, sphenes are ideal minerals for solidifying nucleus waste.

通过对北祁连牛心山变质杂岩体中榍石(775Ma)和山西凤凰山花岗岩中榍石(1758Ma)的XRD及EDS等测试与研究，结果表明：两地榍石的杂质元素质量分数高达8.6%~10.91%，放射性核素锶、铯和铀的质量分数达4.26%~4.58%；晶胞参数的变化极小，△a=-0.0009nm~0.0041nm、△b=0.0018nm~0.0004nm、△c=0.0002nm~-0.0048nm、△β=-0.10°~0.09°，结晶度仍高达99.27%~96.46%，榍石经过10×10^8a的地质作用，结晶度仅减少了3%，显示榍石固化放射性系列核素的能力较强，虽经历了约775Ma~1758Ma的复杂地质演化及其所含放射性核素的衰变作用，其晶体结构完好，稳定性极高，是值得期待的理想核废物固化矿物。

With respect to storage and disposal facilities for radio-active and other hazardous wastes, it is crucial to understand how contaminants move through the geosphere and how long-term performance of disposal facilities can be affected by geological and climatic changes over time.

至于放射性和其他有害废物的储存和处理设施，很关键的一条是必须了解污染物如何在陆界中移动，以及这些处理设施的性能会随着时间的推移，受到地质和气候的影响。

Hazardous solid wastes are substance with toxicity, inflammability, chemical reactivity, infectivity and radioactivity, which make the hazardous solid wastes the potential pollutions and harms to the atmospheric, aquatic, edaphic and ecological environments.

危险废物是指具有毒害性、易燃性、腐蚀性、化学反应性、传染性和放射性的废物，危险废物的特征决定了其对大气、水体、土壤等生态环境破坏存在长期和潜在的隐患。

We're radioactive waste to them, says Greg Kulka, who heads private equity investing for the $12 billion New Mexico State Investment Council, a permanent fund that disburses cash to schools and the state's general fund.

我们正在放射性废物向他们说，格雷格Kulka ，谁负责私人股权投资为120亿美元新墨西哥国家投资理事会，常设基金，支付现金给学校和国家的普通基金。

The comparison between thermal and fast ADS demonstrate that the fast ADS has large power output, less minor actinide production and small fission products poisoning effect compared with thermal system.
