Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The unaudited condensed consolidated financial statements of Centrus Energy Corp. (“Centrus” or the “Company”), which include the accounts of the Company, its principal subsidiary United States Enrichment Corporation (“Enrichment Corp.”) and its other subsidiaries, as of and for the three and nine months ended September 30, 2016 and 2015, have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The condensed consolidated balance sheet as of December 31, 2015 was derived from audited consolidated financial statements, but does not include all disclosures required by generally accepted accounting principles in the United States (“GAAP”). The unaudited condensed consolidated financial statements reflect all adjustments that 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 GAAP have been omitted pursuant to such rules and regulations. All material intercompany transactions have been eliminated. Certain amounts have been reclassified to conform to the current presentation. Operating results for the three and nine months ended September 30, 2016, are not necessarily indicative of the results that may be expected for the year ending December 31, 2016. 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 fiscal year ended December 31, 2015. New Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued a comprehensive standard for revenue recognition and has since issued further implementation guidance. The core principle of the 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 standard will supersede current standards 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 standard requires additional disclosures to describe the nature, amount and timing of revenue and cash flows arising from contracts. The standard will become effective for Centrus beginning with the first quarter of 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. Early adoption as of the first quarter of 2017 is permitted. Centrus expects to adopt the standard in the first quarter of 2018 and is evaluating the impact on its consolidated financial statements. In August 2014, the FASB issued a standard on management’s responsibility to evaluate whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related disclosures in certain circumstances. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. If management identifies such conditions or events, the standard requires disclosures in the notes to the financial statements that outline whether or not there are any plans intended to mitigate the relevant conditions or events to alleviate the substantial doubt. The standard is effective for the Company’s annual reporting period ending December 31, 2016, and for annual and interim periods thereafter. The implementation of the standard is not expected to have a material impact on Centrus’ consolidated financial statements. In April 2015, the FASB issued a standard to simplify the presentation of debt issuance costs. The standard requires the presentation of debt issuance costs in the balance sheet as a reduction in the carrying amount of the related debt liability instead of a deferred charge asset. Centrus adopted the standard with retrospective application beginning with the first quarter of 2016. The reclassification of debt issuance costs did not have a material impact on Centrus’ consolidated financial statements. In February 2016, the FASB issued a standard that requires lessees to recognize a right-of-use asset and lease liability on the balance sheet for all leases with terms longer than 12 months. The standard is effective for Centrus beginning in the first quarter of 2019, and requires expanded disclosures of lease arrangements. Centrus is evaluating the impact of adopting this standard on its consolidated financial statements. In March 2016, the FASB issued a standard for stock compensation that simplifies several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The standard is effective for Centrus beginning in the first quarter of 2017. The implementation of the standard is not expected to have a material impact on Centrus’ consolidated financial statements. In August 2016, the FASB issued a standard related to the presentation and classification of certain cash receipts and cash payments in the statement of cash flows. The standard is intended to reduce diversity in practice by providing guidance on eight specific cash flow issues. The standard is effective for Centrus beginning in the first quarter of 2018. Early adoption is permitted. Centrus is evaluating the impact of adopting this new standard on its consolidated financial statements.

Restructuring and Related Activities [Abstract]
Special Charges	SPECIAL CHARGES Enrichment Cessation and Evolving Business Needs The cessation of enrichment at the Paducah Gaseous Diffusion Plant (the “Paducah GDP”) and evolving business needs have resulted in workforce reductions since July 2013. In the three and nine months ended September 30, 2015, special charges included related termination benefits of $1.1 million and $4.9 million , respectively, less $0.3 million in the nine-month period for employee severance paid by the Company and invoiced to the U.S. Department of Energy (“DOE”) for its share of employee severance pursuant to the USEC Privatization Act. In the second quarter of 2016, the Company commenced a project to align its corporate structure to the scale of its ongoing business operations and to update related information technology. The Company incurred advisory costs related to the reengineering project of $0.3 million in the three months and $0.8 million in the nine months ended September 30, 2016. In addition, special charges in the three and nine months ended September 30, 2016, included termination benefits of $0.3 million related to voluntary workforce reductions. Piketon Demonstration Facility In September 2015, Centrus completed a successful three-year demonstration of American Centrifuge technology at its facility in Piketon, Ohio, with 120 machines linked together in a cascade to simulate industrial operating conditions. The demonstration effort was primarily funded by the U.S. government. As a result of reduced program funding, Centrus incurred a special charge of $8.7 million in the third quarter of 2015 for estimated employee termination benefits, consisting primarily of payments under its pre-existing severance plan. An additional $0.1 million special charge was incurred in the second quarter of 2016 as an adjustment to accrued severance benefits for current salary levels. A summary of termination benefit activity and related liabilities follows (in millions): Liability December 31, 2015 Nine Months Ended September 30, 2016 Liability September 30, 2016 Charges for Termination Benefits Paid Workforce reductions: Enrichment cessation and evolving business needs $ 0.3 $ 0.3 $ (0.2 ) $ 0.4 Piketon demonstration facility 8.4 0.1 (2.9 ) 5.6 $ 8.7 $ 0.4 $ (3.1 ) $ 6.0 Centrus expects to make payments for these workforce reductions through 2019. Of the $6.0 million liability as of September, 30, 2016, $1.2 million is included in Accounts Payable and Accrued Liabilities and $4.8 million is included in Other Long-Term Liabilities .

Contract Services and Advanced Technology Costs and Other Income	CONTRACT SERVICES AND ADVANCED TECHNOLOGY COSTS The contract services segment includes Revenue and Cost of Sales for engineering and testing work Centrus performs on the American Centrifuge technology under government contract with UT-Battelle, LLC (“UT-Battelle”), the operator of Oak Ridge National Laboratory (“ORNL”). Centrus entered into a new contract with UT-Battelle on September 19, 2016, valued at approximately $25 million for the period from October 1, 2016, through September 30, 2017 (the “2017 ORNL Contract”). The 2017 ORNL Contract provides for payments for monthly reports of approximately $2.0 million per month and additional aggregate payments of $1.0 million based on completion of certain milestones. The 2017 ORNL Contract is currently being funded incrementally. Funding for the program is provided to UT-Battelle by the federal government which is currently operating under a continuing resolution. The Company’s contract with UT-Battelle that ended September 30, 2016 (the “2016 ORNL Contract”), provided for payments for monthly reports of approximately $2.7 million per month. The amount of funding under the 2016 ORNL Contract decreased from approximately $6.9 million per month received under contract for the government fiscal year that ended September 30, 2015 (the “2015 ORNL Contract”). Although the 2015 ORNL Contract expired September 30, 2015, Centrus continued to perform work at the expected reduced scope as the parties worked toward a successor agreement. The 2016 ORNL Contract, which was signed in March 2016, provided for payment for reports related to work performed since October 1, 2015. Revenue in the nine months ended September 30, 2016, includes $8.1 million for March reports on work performed in the three months ended December 31, 2015, and $24.2 million for reports on work performed in the nine months ended September 30, 2016. Expenses for contract work performed in the nine months ended September 30, 2016, are included in Cost of Sales . Expenses for work performed in the three months ended December 31, 2015, before entering into the 2016 ORNL Contract, were included in Advanced Technology Costs in 2015. American Centrifuge expenses that are outside of the Company’s contracts with UT-Battelle are included in Advanced Technology Costs, including costs associated with the decontamination and decommissioning (“D&D”) of the Piketon facility in accordance with the requirements of the U.S. Nuclear Regulatory Commission (“NRC”) and DOE. Charges to Advanced Technology Costs in the three and nine months ended September 30, 2016, include approximately $15 million to increase the accrued D&D liability based on updated cost estimates that reflect changes in the approach and anticipated timeframe over which the work will be conducted. Remaining costs to perform the D&D work are estimated to be within a range of $38.9 million to $49.4 million . As of September 30, 2016, Centrus has accrued $38.9 million on the balance sheet as Decontamination and Decommissioning Obligations , of which $28.3 million is classified as current and $10.6 million is classified as long-term. Refer to Note 12, Commitments and Contingencies , for additional details. Advanced Technology Costs also includes ongoing support costs to maintain the facilities at Piketon and our NRC licenses at that location.

Unpaid invoices to DOE totaled approximately $78 million as of September 30, 2016, and December 31, 2015, related to filed claims. Due to the lack of a resolution with DOE and uncertainty regarding the timing and amount of future collections, the long-term receivable for accounting purposes is $23.0 million as of September 30, 2016, and December 31, 2015, including updated submissions for final indirect rates and incurred costs, as well as invoices for interest. Centrus has unapplied payments from DOE that may be used, at DOE’s direction, (a) to pay for future services provided by the Company or (b) to reduce outstanding receivables balances due from DOE. The balance of unapplied payments of $19.3 million as of September 30, 2016, and $19.4 million as of December 31, 2015, is included in other long-term liabilities pending resolution of the long-term receivables from DOE described above.

Inventories	INVENTORIES Centrus holds uranium at licensed locations in the form of natural uranium and as the uranium component of low enriched uranium (“LEU”). Centrus also holds separative work units (“SWU”) as the SWU component of LEU at licensed locations (e.g., fabricators) to meet book transfer requests by customers. Fabricators process LEU into fuel for use in nuclear reactors. Components of inventories follow (in millions): September 30, 2016 December 31, 2015 Current Assets Current Liabilities (a) Inventories, Net Current Assets Current Liabilities (a) Inventories, Net Separative work units $ 146.9 $ 3.7 $ 143.2 $ 221.5 $ 33.1 $ 188.4 Uranium 38.7 18.5 20.2 97.5 73.7 23.8 Materials and supplies 0.2 — 0.2 0.2 — 0.2 $ 185.8 $ 22.2 $ 163.6 $ 319.2 $ 106.8 $ 212.4 (a) Inventories owed to customers and suppliers, included in current liabilities, include SWU and uranium inventories owed to fabricators. Inventories are valued at the lower of cost or net realizable value. Valuation adjustments of $3.0 million were charged to cost of sales in the nine months ended September 30, 2016, including $2.3 million in the third quarter, for the Company’s uranium inventory to reflect declines in uranium market price indicators. Uranium Provided by Customers and Suppliers Centrus held uranium with estimated values of approximately $215 million as of September 30, 2016 , and $437 million as of December 31, 2015 , to which title was held by customers and suppliers and for which no assets or liabilities were recorded on the balance sheet. The reduction reflects a 25% decline in quantities and a 35% decline in uranium spot price indicators. While in some cases Centrus sells both the SWU and uranium components of LEU to customers, utility customers typically provide uranium to Centrus as part of their enrichment contracts. Title to uranium provided by customers generally remains with the customer until delivery of LEU at which time title to LEU is transferred to the customer, and title to uranium is transferred to Centrus.

The Company made cash payments of $9.8 million for PIK Toggle Notes having an aggregate principal balance of $26.1 million and accrued interest payable balance of $0.5 million. The gain on the early extinguishment of the PIK Toggle Notes was $16.7 million , net of commissions and unamortized deferred financing costs totaling $0.1 million . The pre-arranged trading plan was adopted in accordance with guidelines specified under Rule 10b5-1 of the Securities Exchange Act of 1934 (the “10b5-1 Plan”). The 10b5-1 Plan provided that an independent broker selected by the Company repurchase PIK Toggle Notes on the open market within specified guidelines on the Company’s behalf. All repurchases were subject to SEC regulations as well as such other terms and conditions as specified in the 10b5-1 Plan. On July 11, 2016, the Company terminated the 10b5-1 Plan and subsequently cancelled the PIK Toggle Notes that were repurchased. The PIK Toggle Notes pay interest at a rate of 8.0% per annum. Interest is payable semi-annually in arrears based on a 360-day year consisting of twelve 30-day months. The principal amount is increased by any payment of interest in the form of PIK payments. The Company has the option to pay up to 5.5% per annum of interest due on the PIK Toggle Notes in the form of PIK payments. For payments in 2016 and through the semi-annual interest period ending March 31, 2017, the Company has elected to pay interest in the form of PIK payments at 5.5% per annum. Financing costs for the issuance of the PIK Toggle Notes were deferred and are being amortized on a straight-line basis, which approximates the effective interest method, over the life of the PIK Toggle Notes. The PIK Toggle Notes will mature on September 30, 2019. However, the maturity date can be extended to September 30, 2024, upon the satisfaction of certain funding conditions described in the Indenture relating to the funding, under binding agreements, of (i) the American Centrifuge project or (ii) the implementation and deployment of a National Security Train Program utilizing American Centrifuge technology. The PIK Toggle Notes rank equally in right of payment with all existing and future unsubordinated indebtedness of the Company (other than the Issuer Senior Debt as defined below) and are senior in right of payment to all existing and future subordinated indebtedness of the Company. The PIK Toggle Notes are subordinated in right of payment to certain indebtedness and obligations of the Company described in the Indenture (the “Issuer Senior Debt”), including (i) any indebtedness of the Company under a future credit facility, (ii) obligations of, and claims against, the Company under any equity investment (or any commitment to make an equity investment) with respect to the financing of the American Centrifuge project, (iii) obligations of, and claims against, the Company under any arrangement with DOE, export credit agencies or any other lenders or insurers with respect to the financing or government support of the American Centrifuge project and (iv) indebtedness of the Company to Enrichment Corp. under the Centrus Intercompany Note. The PIK Toggle Notes are guaranteed and secured on a subordinated, conditional, and limited basis by Enrichment Corp.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Pursuant to the accounting guidance for fair value measurements, fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, consideration is given to the principal or most advantageous market and assumptions that market participants would use when pricing the asset or liability. The accounting guidance establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value: • Level 1 – quoted prices in active markets for identical assets or liabilities. • Level 2 – inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. • Level 3 – unobservable inputs in which little or no market data exists. Financial Instruments Recorded at Fair Value (in Millions) September 30, 2016 December 31, 2015 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Cash and cash equivalents $ 170.8 $ — $ — $ 170.8 $ 234.0 $ — $ — $ 234.0 Deferred compensation asset (a) 1.1 — — 1.1 — 1.5 — 1.5 Liabilities: Deferred compensation obligation (a) 1.1 — — 1.1 — 1.4 — 1.4 (a) The deferred compensation obligation represents the balance of deferred compensation plus net investment earnings. The deferred compensation plan is funded through a rabbi trust. As of September 30, 2016, trust funds were invested in mutual funds for which unit prices are quoted in active markets and are classified within Level 1 of the valuation hierarchy. As of December 31, 2015, the trust was informally funded using variable universal life insurance. The cash surrender value of the life insurance policies was designed to track the deemed investments of the plan participants. Investment crediting options consisted of institutional and retail investment funds. The deemed investments were classified within Level 2 of the valuation hierarchy because (i) of the indirect method of investing and (ii) unit prices of institutional funds are not quoted in active markets. The transfers from Level 2 to Level 1 noted above comprised the only transfers between Levels 1, 2 or 3 during the periods presented. Other Financial Instruments As of September 30, 2016 , and December 31, 2015, the balance sheet carrying amounts for accounts receivable, accounts payable and accrued liabilities (excluding the deferred compensation obligation described above), and payables under SWU purchase agreements approximate fair value because of the short-term nature of the instruments.

The remeasurement resulted in a loss of $0.8 million included in selling, general and administrative expenses in the second quarter of 2016. The loss includes the effect of a decrease in the discount rate used in the measurement of pension obligations from approximately 4.5% as of December 31, 2015, to approximately 3.7% as of June 30, 2016. In the second quarter of 2015, the level of lump-sum payments under the Company’s non-qualified defined benefit pension plans and the Employees’ Retirement Plan of Centrus Energy Corp. resulted in a remeasurement gain of $3.9 million included in selling, general and administrative expenses. The gain included the effect of an increase in the discount rate from approximately 4.1% as of December 31, 2014, to approximately 4.5% as of June 30, 2015. In the third quarter of 2015, the level of lump-sum payments under the Retirement Program Plan for Employees of United States Enrichment Corporation and the plans mentioned above resulted in a remeasurement loss of $21.6 million included in cost of sales and a loss of $3.2 million included in selling, general and administrative expenses. The discount rate used in the measurement of pension obligations as of September 30, 2015 was approximately 4.4% . The losses also include the effect of actual investment experience for pension plan assets relative to the expected return assumption of 6.75% per year.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share	NET INCOME (LOSS) PER SHARE Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period, excluding any unvested restricted stock. In calculating diluted net income per share, the numerator is increased by interest and dividends on potentially dilutive securities, net of tax, and the denominator is increased by the weighted average number of shares resulting from potentially dilutive securities, assuming full conversion. No dilutive effect is recognized in a period in which a net loss has occurred.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Potential ERISA Section 4062(e) Liability The Company had been engaged in discussions with the PBGC regarding the status of the qualified pension plans, including potential liability under ERISA Section 4062(e) related to employee reductions resulting from ceasing enrichment operations at the Portsmouth and Paducah GDP facilities. In the event the PBGC were to determine there are funding obligations under section 4062(e), the Company believes that any such liability would be fully satisfied under the provisions of the Consolidated and Further Continuing Appropriations Act, 2015 (the “CFCAA”), which made major changes to ERISA section 4062(e). The CFCAA changes the criteria for triggering liability under section 4062(e); provides certain exemptions from the applicability of section 4062(e) to certain events; permits companies to satisfy the liability by making payments into the pension over seven years, but ends those pension obligations once the pension reaches a 90% funding level as calculated under the method provided in the CFCAA; subject to an exception not applicable here, prohibits the PBGC from taking any enforcement, administrative or other action under section 4062(e) that is inconsistent with the amendments made by the CFCAA based on events that occurred before the date of enactment (December 16, 2014); and permits companies to elect to satisfy any liability under section 4062(e) as provided in the CFCAA for an event that had occurred prior to date of enactment as if such cessation had occurred on such date of enactment. The PBGC, however, has other authorities under ERISA that it may otherwise consider in connection with the Company’s qualified defined benefit pension plans. These authorities include, but are not limited to, initiating involuntary termination of underfunded plans and seeking liens or additional funding. The Company would seek to defend against the assertion by the PBGC of any such authorities based on the facts and circumstances at the time. The involuntary termination by the PBGC of any of the qualified pension plans of Centrus or Enrichment Corp. would result in the termination of the limited, conditional guaranty by Enrichment Corp. of the PIK Toggle Notes (other than with respect to certain interest obligations). The PBGC has indicated it would like the Company to make contributions to the pension in advance of statutory funding requirements as amended by the Highway and Transportation Funding Act of 2014. The Company believes it is in the best interest of all stakeholders, including the PBGC, the covered plan participants and the Company, to continue funding the qualified pension plans in the ordinary course and expects to do so. There is no assurance that the Company and the PBGC will reach agreement or that the PBGC will agree with the Company’s approach. NYSE MKT Listing Standards Notice On November 17, 2015, Centrus Energy Corp. received notice from the NYSE MKT LLC (the “NYSE MKT”) indicating that the Company is not in compliance with Sections 1003(a)(i) and (ii) of the NYSE MKT's Company Guide since the Company reported a stockholders’ deficit as of September 30, 2015, and net losses in its fiscal years ended December 31, 2011, 2012 and 2013. The Company submitted a plan to regain compliance with the NYSE MKT’s continued listing standards and the NYSE MKT notified the Company in January 2016 that it accepted the plan. With the NYSE MKT’s acceptance of the plan, the Company has until May 17, 2017, to regain compliance. If the Company is not in compliance with the continued listing standards by May 17, 2017, or if the Company does not make progress consistent with the plan, the NYSE MKT may initiate delisting procedures as appropriate. In the meantime, the Company’s common stock will continue to be traded on the NYSE MKT, subject to ongoing monitoring by the NYSE MKT and the Company’s compliance with all other applicable NYSE MKT requirements. American Centrifuge Milestones under the 2002 DOE-USEC Agreement USEC and DOE signed an agreement dated June 17, 2002, as amended (the “2002 DOE-USEC Agreement”), pursuant to which the parties made long-term commitments directed at resolving issues related to the stability and security of the domestic uranium enrichment industry. DOE consented to the assumption by Centrus of the 2002 DOE-USEC Agreement and other agreements between the Company and DOE subject to an express reservation of all rights, remedies and defenses by DOE and Centrus under those agreements as part of Centrus' Chapter 11 bankruptcy process. The 2002 DOE-USEC Agreement requires Centrus to develop, demonstrate and deploy advanced enrichment technology in accordance with milestones and provides for remedies in the event of a failure to meet a milestone under certain circumstances. DOE has specific remedies under the 2002 DOE-USEC Agreement if Centrus fails to meet a milestone that would adversely impact its ability to begin commercial operations of the American Centrifuge Plant on schedule, and such delay was within Centrus’ control or was due to its fault or negligence or if Centrus abandons or constructively abandons the commercial deployment of an advanced enrichment technology. These remedies include terminating the 2002 DOE-USEC Agreement, revoking Centrus’ access to DOE’s centrifuge technology that is required for the success of the American Centrifuge project, requiring Centrus to transfer certain rights in the American Centrifuge technology and facilities to DOE, and requiring Centrus to reimburse DOE for certain costs associated with the American Centrifuge project. The 2002 DOE-USEC Agreement provides that if a delaying event beyond the control and without the fault or negligence of Centrus occurs that could affect Centrus’ ability to meet an American Centrifuge Plant milestone, DOE and Centrus will jointly meet to discuss in good faith possible adjustments to the milestones as appropriate to accommodate the delaying event. The Company notified DOE that it had not met the June 2014 milestone within the time period currently provided due to events beyond its control and without the fault or negligence of the Company. The assumption of the 2002 DOE-USEC Agreement provided for under the Plan of Reorganization did not affect the ability of either party to assert all rights, remedies and defenses under the agreement and all such rights, remedies and defenses are specifically preserved and all time limits tolled expressly including all rights, remedies and defenses and time limits relating to any missed milestones. DOE and Centrus have agreed that all rights, remedies and defenses of the parties with respect to any missed milestones since March 5, 2014, including the June 2014 and November 2014 milestones, and all other matters under the 2002 DOE-USEC Agreement continued to be preserved, and that the time limits for each party to respond to any missed milestones continue to be tolled. Piketon Facility Costs and D&D Obligations Effective October 1, 2015, the U.S. government discontinued funding of the American Centrifuge demonstration cascade at Piketon. Funding for American Centrifuge is now limited to research and development work at our facilities in Oak Ridge, Tennessee. As a result of reduced program funding, Centrus incurred a special charge in the third quarter of 2015 for estimated employee termination benefits, and began reductions in force. Refer to Note 2, Special Charges , for details. Centrus began to incur expenditures in the second quarter of 2016 associated with the decontamination and decommissioning (“D&D”) of the Piketon facility in accordance with the requirements of the NRC and DOE. Centrus leases the Piketon facility from DOE. At the conclusion of the lease, Centrus is obligated to return the facility to DOE in a condition that meets NRC requirements and in the same condition as the facility was in when it was leased to Centrus (other than due to normal wear and tear). Centrus must remove all Company-owned capital improvements at the Piketon facility, unless otherwise consented to by DOE, by the conclusion of the lease term. The lease will expire on June 30, 2019, unless it is extended. Remaining costs to perform the D&D work are estimated to be within a range of $38.9 million to $49.4 million based on updated cost estimates that reflect changes in the approach and anticipated timeframe over which the work will be conducted, as described below. As of September 30, 2016, Centrus has accrued $38.9 million on the balance sheet as Decontamination and Decommissioning Obligations , of which $28.3 million is classified as current and $10.6 million is classified as long-term. Centrus has experienced delays in obtaining the necessary regulatory approvals and therefore implementing the D&D process has been delayed. Centrus is working to finalize contractual and regulatory arrangements for the disposition of materials. As a result of the delays experienced in obtaining regulatory approvals, Centrus has revised its schedule and approach to completing D&D in order to minimize the impact of such delays and to mitigate future cost and schedule risk. The D&D work is expected to extend through 2018. Centrus is required to provide financial assurance to the NRC and DOE for D&D costs under a regulatorily-prescribed methodology that includes potential contingent costs and reserves. As of September 30, 2016, and December 31, 2015, Centrus has provided financial assurance to the NRC and DOE in the form of surety bonds totaling $29.4 million , which are fully cash collateralized by Centrus. Centrus expects to receive cash when surety bonds are reduced and/or cancelled as the Company fulfills its D&D and lease obligations. The Company has not made a decision on lease turnover and is continuing to evaluate future uses for the site.
