摘要
为实现全球温室气体排放总量到2050年降低50%的目标,以及对电力快速增长的需求,大规模发展核电已成为各国的重要选择。今后至少20年内,核电将出现新一轮的高速发展,对铀矿资源的需求随之大幅度增加。全球常规铀矿资源量约为1238万tU,另外,非常规铀矿资源量可能高达近3000万tU,完全可以满足人类未来核电发展的需要。我国铀矿资源贫乏,铀矿资源量仅为7.4万tU,目前的年产量只有750tU。根据核电发展趋势,到2030年,国内核电对铀矿资源的年需求量将达2.2万～4.5万tU,2010～2030年期间累计需求将达28万～52万tU,绝大部分需求将不得不依赖国外。本文针对我国铀矿资源可能出现供需严重失衡的局面,就如何获取海外铀矿资源、确保核燃料供应安全问题提出了建议。
In order to meet the target of greenhouse gas emission reduction by 50% by 2050, and the fast-growing demand for electricity, development of nuclear power on a large scale has been becoming an important national selection for many countries. In the forthcoming 20 years, nuclear power will welcome in a new round of rapid development, as well as the due great demand for uranium resources. The amount of global conventional uranium resources is about 12. 38 million tU, and that of unconventional uranium resources is likely to approach 30 million tU, which could fully meet the demand of mankind＇s future nuclear power development. With only about 74 000 tU, the amount of uranium resources of China is scarce, and the annual yield is only 750 tU. According to current development trend, the domestic demand for uranium resources will reach 22000-45000 tU in 2030, and the aggregate demand during 2010-2030 period will reach as high as 280000-520000 tU, indicating that most of the demand will have to rely on abroad. According to the possibly serious supply-demand imbalance of uranium resources in China, some specific recommendations were put forward for how to obtain oversea uranium resources and to ensure the security of nuclear fuel supply.
