Q: There is a deadline by the end of this year for Iran to swap lowly-enriched uranium for nuclear fuel, or face more sanctions. What's China position's on this?
问：今年底伊朗用低浓缩铀换取核燃料将到最后期限，否则将面临制裁，中方对此持何立场？
The UO2 fuel is normally enriched with 3-5% of U235. The uranium alloy has been enriched to contain up to 90% U235, but is normally used at between 45-75% U235 enrichment in PWR for ships propulsion.
UO 2一般内含3- 5%的U235，而铀合金经过浓缩则含有90%的U235，但是船用推进器一般使用U 235含量为45 - 75%的浓缩铀。
For the next ten years, its uranium fuel (enriched to under 5%) will come from Russia too and the spent fuel will go back there.
未来十年，其铀燃料(浓缩至低于百分之五)也是来自俄罗斯，已使用的燃料又会被俄罗斯回收。
The move comes amid a worsening stand-off over a Western offer for Iran to swap enriched uranium for nuclear fuel.
