80年代以来,世界范围的铀矿勘探和生产开始走向低潮,但是当前铀矿的发展在经受了连续衰退之后,也呈现出了回升的一线希望,主要表现在:切尔诺贝利核电站事故的阴影开始驱散,各国正重新修改和制定核电发展战略,旨在提高核电在总发电量中的比重。1986年的核电增长率增加了7％,全世界在该年内增加了21座核电站。在铀生产方面,1985年的铀产量第一次产低于求;铀矿勘探费用虽然水平较低,但基本保持稳定。非中央计划经济国家中成本低于80美元/kg的铀可靠资源1985年为l609000t,介于80—130美元/kg的为630000t,两类合计为2239000t。低成本可靠资源的增加主要依赖于澳大利亚、南非、加拿大、墨西哥以及印度、意大利和尼日尔。1985年铀成本低于80美元/kg的估计附加资源为897000t,介于
Since the 1980s, the world-wide uranium exploration and production began to decline, but the current development of uranium mines has shown a hope of recovery after undergoing a continuous recession, mainly reflected in the accident at the Chernobyl nuclear power plant. The shadows began to disperse, and countries are revising and formulating nuclear power development strategies aimed at increasing the proportion of nuclear power in total power generation. The growth rate of nuclear power in 1986 increased by 7%. The world increased 21 nuclear power plants during the year. In terms of uranium production, the first production of uranium production in 1985 was lower than the demand; the exploration costs of uranium deposits remained stable although they were relatively low. The uranium-reliable resources costing less than US$80/kg in non-central state-planned economies were 6,000,000 tons in 1985, 630,000 tons in the range of US$80-130/kg, and 2239,000 tons in both categories. The increase in low-cost and reliable resources mainly depends on Australia, South Africa, Canada, Mexico, India, Italy, and Niger. Estimated additional resources for uranium costs below $80/kg in 1985 are 89,700t.
