Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION Nature of Operations On March 5, 2014, USEC Inc. filed a voluntary petition for relief (the "Bankruptcy Filing") under Chapter 11 of Title 11 of the United States Code (the "Bankruptcy Code") in the United States Bankruptcy Court for the District of Delaware (the "Bankruptcy Court"). The Bankruptcy Filing was "pre-arranged" and included the filing of a proposed Plan of Reorganization (the "Plan of Reorganization") supported by certain holders of the claims and interests impaired under the Plan of Reorganization. On August 18, 2014, the Company announced that the Plan of Reorganization was accepted by more than 99% in both value and number of votes cast of holders of its convertible notes and that both holders of the Company’s preferred equity voted in favor of the Plan of Reorganization. On September 5, 2014, the Bankruptcy Court entered an order approving and confirming the Plan of Reorganization. On September 30, 2014 (the "Effective Date"), the Company satisfied the conditions of the Plan of Reorganization and the Plan of Reorganization became effective. On the Effective Date, USEC Inc.’s name was changed to Centrus Energy Corp. ("Centrus" or the "Company"). In accordance with Accounting Standards Codification Topic 852, Reorganizations, Centrus adopted fresh start accounting upon emergence from Chapter 11 bankruptcy resulting in Centrus becoming a new entity for financial reporting purposes. References to "Successor" or "Successor Company" relate to the financial position of the reorganized Centrus as of and subsequent to September 30, 2014 and results of operations for the three months ended December 31, 2014. References to "Predecessor" or "Predecessor Company" refer to the financial position of the Company prior to September 30, 2014 and the results of operations through September 30, 2014. As a result of the application of fresh start accounting and the effects of the implementation of the Plan of Reorganization, the financial statements on or after September 30, 2014 are not comparable with the financial statements prior to that date. Refer to Note 4, Fresh Start Accounting, for additional information. The Bankruptcy Filing was intended to strengthen the Company’s balance sheet, improve its long-term business prospects and address a very specific and impending debt maturity. With the successful conclusion of the balance sheet restructuring, the Company achieved (a) a 55% reduction in the amount of third party debt obligations outstanding and the elimination of all shares of convertible preferred stock; (b) an extension of maturity payments for at least five years, and potentially another five years if certain conditions are met, as a result of the cancellation of its former debt and issuance of new debt; and (c) a reduction in the annual cash interest burden, as a result of the cancellation of its former debt and issuance of new debt, which has a pay in-kind interest feature. Furthermore, the new debt contains minimal covenants that will not constrain Centrus from managing and operating its business in the normal course. Centrus is a supplier of low enriched uranium ("LEU") for nuclear power plants. The benefits of the balance sheet restructuring provide stability and continuity for Centrus’ LEU commercial operations, conducted primarily through its wholly owned subsidiary United States Enrichment Corporation ("Enrichment Corp."). Moving forward, Centrus expects to continue Enrichment Corp.'s operations by selling its current inventory quantities, as well as commercial LEU purchased from Russia and from other suppliers, to customers under contract and through new commercial sales. With the successful conclusion of the balance sheet restructuring, Centrus has substantially reduced its leverage and extended maturity payments for at least five years. Centrus expects to comply with the covenants contained in the indenture governing its new debt. Having successfully implemented the Plan of Reorganization and emerged from bankruptcy on the Effective Date, Centrus anticipates having adequate liquidity for at least the next 12 months. As a result of these factors, management believes there is no longer substantial doubt regarding the Company’s ability to continue as a going concern. Expenses, gains and losses directly associated with reorganization proceedings are reported as Reorganization Items, Net, in the accompanying consolidated statement of operations. In March 2013, the Company’s wholly owned subsidiary NAC International, Inc. ("NAC") was acquired by Hitz Holdings U.S.A. Inc., a subsidiary of Hitachi Zosen Corporation. The Company recorded a gain on the sale of $35.6 million in the first quarter of 2013. Results for NAC through the date of divestiture of March 15, 2013 are segregated from continuing operations and reported as discontinued operations.
