Although the issue has been much debated, until now there has been only modest progress in developing fuel-supply assurance arrangements that would meet this concern. Russia, with the support of the International Atomic Energy Agency (IAEA), maintains a sizeable reserve of low-enriched uranium (LEU) at its international center in Angarsk; but, in the current security environment, there has been understandable international reluctance to rely on it.
尽管这一问题经过了大量争论，但到目前为止，在制定燃料供给保障安排以解决这一担忧方面，进展十分有限。在国际原子能机构的支持下，俄罗斯安加尔斯克（Angarsk）国际中心保留了大量低浓缩铀储备；但是，在当前的安全环境下，不难理解国际社会不愿意依赖这些能源。英国已提出其自身的供给保障安排，尽管到目前为止没有受到多少关注。
