A finanical Times article (Page 15, Dec 6, 2010) describes the takeover of Uranium One of Canada by ARMZ – a Russian state owned company and now owns two mines in Wyoming.  The impact is loss of control by the US of key parts of the nuclear supply chain, according to the article.  The deal was approved by the US Nuclear Regulatory Commission as well as the Committee on Foreign Investment in the US. Is it relevant to consider foreign ownership of portions of the US nuclear supply chain ? Or would market forces and self interest keep prices and availability competitive ?
