Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION 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") supported by certain holders of the claims and interests impaired under the reorganization plan. On August 18, 2014, the Company announced that the Plan was accepted by more than 99 percent 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. On September 5, 2014, the Bankruptcy Court entered an order approving and confirming the Plan. On September 30, 2014 (the "Effective Date"), the Company satisfied the conditions of the Plan and the Plan became effective. On the Effective Date, USEC Inc.’s name was changed to Centrus Energy Corp. ("Centrus" or the "Company"). 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. The benefits of the balance sheet restructuring also provide stability and continuity for Centrus’ low enriched uranium ("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 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. 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 September 30, 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, the financial statements on or after September 30, 2014 are not comparable with the financial statements prior to that date. Refer to Note 3, "Fresh Start Accounting", for additional information. Expenses, gains and losses directly associated with reorganization proceedings are reported as Reorganization Items, Net, in the accompanying Condensed Consolidated Statement of Operations. The unaudited condensed consolidated financial statements of Centrus as of and for the three and nine months ended September 30, 2014 and 2013 have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). The unaudited condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the financial results for the interim period. Certain information and notes normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("GAAP") have been omitted pursuant to such rules and regulations. All material intercompany transactions are eliminated. Certain amounts in the condensed consolidated financial statements have been reclassified to conform to the current presentation. 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. Operating results for the three and nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. The unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes and Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Annual Report on Form 10-K for the year ended December 31, 2013. New Accounting Standards In July 2013, the Financial Accounting Standards Board ("FASB") issued guidance requiring an entity to present unrecognized tax benefits as a reduction to deferred tax assets when a net operating loss carryforward, similar tax loss or a tax credit carryforward exists, with limited exceptions. This pronouncement was effective beginning in the first quarter of 2014. The Company has historically presented uncertain tax positions in accordance with the new guidance and the implementation of the guidance did not have a material impact on its consolidated financial statements. In April 2014, the FASB issued amendments to guidance for reporting discontinued operations and disposals of components of an entity. The amended guidance changes the definition of a discontinued operation to include only those disposals of components of an entity that represent a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. The amendments also expand the disclosure requirements for discontinued operations and add new disclosures for individually significant dispositions that do not qualify as discontinued operations. The amendments are effective prospectively beginning in the first quarter of 2015 (early adoption is permitted only for disposals that have not been previously reported). The implementation of the amended guidance is not expected to have a material impact on Centrus' results of operations, cash flows or financial position. In May 2014, the FASB issued comprehensive new guidance for revenue recognition. The core principle of the new standard is that revenue should be recognized when an entity transfers promised goods or services to customers in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The new standard will supersede current guidance in effect and may require the use of more judgment and estimates, including estimating the amount of variable revenue to recognize over each identified performance obligation. The new standard requires additional disclosures to describe the nature, amount and timing of revenue and cash flows arising from contracts. The new standard will become effective for Centrus beginning with the first quarter of 2017 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. Centrus is evaluating the impact of adopting this new guidance on its consolidated financial statements. In August 2014, the FASB issued guidance which will require management to evaluate whether there is substantial doubt about the entity’s ability to continue as a going concern for 12 months following the issuance of the financial statements. In the event there is substantial doubt, the guidance requires disclosure of the relevant facts and circumstances. This standard is effective for annual reporting periods beginning after December 15, 2016, and interim periods thereafter. Early adoption is permitted. Centrus does not expect this standard will have a significant impact on its consolidated financial statements or disclosures.
