英国新闻听力 乌克兰宣布销毁其所有高浓缩铀储藏（在线收听）

As leaders from nearly 50 countries meet in Washington for a major summit on Nuclear Security, Ukraine has pledged to eliminate stockpile of highly enriched uranium by 2012. Ukraine will also convert its several nuclear research facilities to use low enriched uranium. The summit, the biggest international meeting hosted by the US since 1945, has been called by president Obama. Our diplomatic correspondent Jonathan Marcus reports from Washington.

The timing may have been choreographed for the decision by the Ukraine authorities is just the sort of news president Barack Obama wants to hear. This summit is all about securing stocks of fissile material, highly enriched uranium and plutonium could potentially be used by terrorists to build a nuclear bomb. US officials said that Ukraine has sufficient highly enriched uranium for several nuclear weapons. This will be removed with some help from the United States. This is a precedent Obama would like other countries to follow and just to underscore the gravity of the potential threat. John Briton, a senior US counter-terrorism official, has warned that al-Qaeda has been seeking material for a nuclear bomb for over 15 years and that interest remains strong.

The body of the Polish president’s wife has now been identified following Saturday’s plane crash in Russia, in which she, her husband Lech Kaczynski, and dozens of senior Polish political and military officials were killed. The remains of most of the 96 people have now been recovered from the crash site in Western Russia. Richard Galpin reports from Moscow.

Investigators say the body of Maria Kaczynski was identified by her brother who flew to Moscow to carry out the distressing task. So far, they’ve identified 17 bodies. It’s thought DNA testing would be needed in some cases because of the impact of the crash and the fire that followed. Investigators are now reported to have almost finished reading the information on the plane’s data recorders or black boxes. A senior minister told the Russian president Dmitry Medvedev that the crew of the Polish president’s plane had received the warnings from the control tower that they should not land there because of the bad weather conditions.

来自世界上接近50个国家的领导人在华盛顿参加核安全峰会，乌克兰承诺2012年之前消除高浓缩铀。乌克兰几座核设施也将改用低浓缩铀。这次峰会是1945年以来美国主持召开的最大的国际会议，由奥巴马总统发起。我们的外交记者Jonathan Marcus在华盛顿报道。

这个时间可能是经过精心策划的，因为乌克兰当局宣布的决定正是奥巴马总统希望听到的消息。这次峰会全部是关于核燃料储备问题，高浓缩铀和钚可能被恐怖分子用来制造核弹。美国官员表示，乌克兰的高浓缩铀储备足够制造几个核武器。这些高浓缩铀将在美国的帮助下进行转移。这是奥巴马总统希望其他国家效仿的先例，同时强调核威胁的严重性。美国高级反恐官员John Briton警告称，15年来，基地组织一直寻求核材料来制造核弹，而且他们的兴趣依然非常强烈。
