俄罗斯暂时限制向美国出口浓缩铀，此举给在美国运营反应堆的公用事业公司带来了潜在供应风险，美国近五分之一发电量来自这些反应堆。

　　俄罗斯政府在周五的Telegram声明中没有提供有关限制措施及其持续时间的细节。公用事业公司往往会提前很长时间购买原物料，因此影响不太可能是立竿见影。

　　跟踪铀燃料市场的UxC公司总裁Jonathan Hinze说，虽然今年大部分铀燃料已经交付，但禁令可能会从2025年开始产生影响，这可能会使一些反应堆运营商没有替代供应。

　　获得进口俄罗斯反应堆燃料豁免的公司包括美国最大核电运营商Constellation Energy Corp．、核燃料供应商Centrus Energy Corp．。其他豁免请求仍在等待批复。 Constellation Energy周五在纽约市场一度下跌1.7%。
