                       Report of Independent Accountants


To the USEC Benefit Plan Administrative and Investment Committees and
Participants of the USEC Savings Program

In our opinion, the accompanying  statement of net assets available for benefits
and the  related  statement  of  changes in net assets  available  for  benefits
present fairly, in all material respects,  the net assets available for benefits
of the USEC Savings Program (the "Plan") at December 31, 2001 and the changes in
net assets  available  for benefits for the year then ended in  conformity  with
accounting principles generally accepted in the United States of America.  These
financial  statements  are the  responsibility  of the  Plan's  management;  our
responsibility  is to express an opinion on these financial  statements based on
our  audit.  We  conducted  our audit of these  statements  in  accordance  with
auditing  standards  generally  accepted in the United States of America,  which
require that we plan and perform the audit to obtain reasonable  assurance about
whether the financial  statements  are free of material  misstatement.  An audit
includes  examining,  on a test  basis,  evidence  supporting  the  amounts  and
disclosures in the financial  statements,  assessing the  accounting  principles
used and  significant  estimates made by management,  and evaluating the overall
financial  statement  presentation.   We  believe  that  our  audit  provides  a
reasonable basis for our opinion.

Our audit was  conducted  for the  purpose  of  forming  an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets (held
at end of year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements but is supplementary information
required by the  Department of Labor's Rules and  Regulations  for Reporting and
Disclosure  under the Employee  Retirement  Income  Security  Act of 1974.  This
supplemental  schedule  is the  responsibility  of the  Plan's  management.  The
supplemental  schedule has been subjected to the auditing  procedures applied in
the audit of the basic  financial  statements  and,  in our  opinion,  is fairly
stated in all material  respects in relation to the basic  financial  statements
taken as a whole.

Report of independent public accountants



To the Trustees of the
USEC Inc. 401(k) Retirement Savings Plan:

We have audited the accompanying statements of net assets available for benefits
of the USEC Inc.  401(k)  Retirement  Savings Plan (the Plan) as of December 31,
2000 and 1999, and the related statements of changes in net assets available for
benefits  for the  years  ended  December  31,  2000 and 1999.  These  financial
statements are the responsibility of the plan management.  Our responsibility is
to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable  assurance about whether the financial  statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting  the amounts and  disclosures in the financial  statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the net assets available for benefits of the Plan as of
December  31,  2000 and 1999,  and the changes in its net assets  available  for
benefits for the years then ended,  in  conformity  with  accounting  principles
generally accepted in the United States.

Our audit was made for the purpose of forming an opinion on the basic  financial
statements taken as a whole. Supplemental schedule of assets held for investment
purposes is presented for purposes of additional  analysis and is not a required
part of the basic financial statements but is supplementary information required
by the Department of Labor's Rules and  Regulations for Reporting and Disclosure
under the Employee  Retirement  Income Security Act of 1974.  This  supplemental
schedule  is the  responsibility  of the Plan  administrator.  The  supplemental
schedule has been subjected to the auditing  procedures applied in the audits of
the basic  financial  statements  and, in our opinion,  is fairly  stated in all
material  respects  in  relation to the basic  financial  statements  taken as a
whole.

The accompanying notes are an integral part of these statements. 4 USEC Savings Program Notes to financial statements 1. Plan description: The following description of the USEC Savings Program (the Plan), formerly known as the USEC Inc. 401(k) Retirement Savings Plan, provides only general information. Plan participants should refer to the Plan document for a more complete description of the Plan's provisions. General Effective January 1, 1994, USEC Inc. (the Company) established a defined contribution retirement savings plan pursuant to Section 401(k) of the Internal Revenue Code (IRC). Until December 31, 2000, the Plan covered all full-time employees of USEC Inc., except certain employees participating in other federal government retirement plans. Effective January 1, 2001, the Plan was amended and restated to allow participation by noncollectively bargained employees of United States Enrichment Corporation, a subsidiary of USEC Inc. As of this date, the name of the Plan was changed to the USEC Savings Program and assets with respect to eligible employees of United States Enrichment Corporation were merged with and into the Plan. The provisions of the restated Plan are intended to include all provisions necessary to preserve such benefits, rights, and features of the United States Enrichment Corporation Savings Program that are required to be preserved under IRS Code Section 411. Net assets transferred to the Plan as a result of the aforementioned amendment were approximately $125 million. The Plan is administered by the Company through its plan administrator. USEC Inc. and the United States Enrichment Corporation are participating employers. The USEC Benefit Plan Administrative and Investment Committees monitor and oversee administration of the Plan. Fidelity Management Trust Company (the Trustee or FMTC) acts as Trustee and recordkeeper. Contributions Effective January 1, 2001, participants may contribute between 1 percent and 21 percent of eligible compensation in .5% increments up to the maximum annual amount allowed under the IRC. Prior to January 1, 2001 before tax contributions were limited to 15% of eligible compensation. Participants may elect either before tax contributions, after-tax contributions or a combination of both. For each payroll period, the participating employer provides a 100 percent matching contribution for the first 3 percent of each participant's eligible earnings and a 50 percent matching contribution for the next 2 percent. Participant accounts and loans Participant's accounts are credited with the participant's and participating employer's matching contributions, and the respective investment earnings (losses) of the individual funds. Allocations are based on participant earnings on account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. 5 Participants may borrow from the Plan in any amount greater than $1,000 but less than 50 percent of the participants' vested account balance. In no event can the participant borrow more than $50,000. Loan terms are for a period not to exceed five years, except for loans taken for the purchase of a primary residence (home loans) which may have terms up to ten years. Loans are secured by the balance in the participant's account and bear a reasonable rate of interest. Principal and interest on the loan are repaid in substantially level installments. As of December 31, 2001, interest rates ranged from 6.0 percent to 10.5 percent. Expenses Expenses of the Plan, except participant loan costs and fund investment management expenses that are paid by the participant, are paid by the Company and amounted to $18,315 and $15,361 in 2001 and 2000, respectively. Vesting Participants are immediately vested in their contributions and associated earnings (losses). Effective January 1, 2001, vesting in the participating employer's matching contributions and associated earnings (losses) is based on years of service, as follows: Years of credited service Percentage --------- ---------- Less than 2 0% 2 50 3 100% Prior to January 1, 2001, vesting in the participating employer's matching contributions and associated earnings (losses) were based on years of service, as follows: Years of credited service Percentage --------- ---------- Less than 2 0% 2 50 3 75 4 100% Forfeitures At December 31, 2001 and 2000, forfeited non-vested accounts totaled $57,068 and $12,615, respectively. Forfeitures are used to reduce current or future matching employer contributions. In 2001 and 2000, employer contributions were reduced by $45,676 and $28,872, respectively, from forfeited non-vested accounts. Investment options Participants direct FMTC to invest their contributions, the participating employer's matching contributions and associated earnings (losses) among twenty-two investment options. Investment options consist of 19 mutual funds, two stock funds and a managed fund of guaranteed investment contracts (the Stable Value Fund). Participants may make exchanges among the investment options at any time by contacting FMTC directly. 6 Benefit payments On termination of service due to retirement (participant eligible for an immediate pension under a deferred benefit plan maintained by a participating employer) or disability, a participant may elect to receive either a lump sum amount equal to the value of the participant's vest interest in his or her account, monthly installments over a fixed number of years or life expectancy or in a series of partial payments. If a participant dies before the entire vested portion of the account is distributed, the remaining vested portion of the account is payable to a beneficiary. For termination of service for other reasons, the vested portion of a participant's account is paid as a lump sum. The amount of any payment from a participant account is reduced as appropriate to satisfy tax withholding requirements. Participants may make hardship withdrawals from their contributions under certain circumstances allowed by the Plan. Plan termination Although it has not expressed any intent to do so, the participating employers have the right to discontinue their contributions at any time and to terminate the Plan subject to the provisions of the IRC. In the event of Plan termination, participants will become 100 percent vested in participating employer matching contributions and associated earnings. 2. Summary of significant accounting policies: Basis of accounting The financial statements of the Plan are prepared based on the accrual method of accounting except that benefits are recorded when paid, as required by accounting principles generally accepted in the United States of America. Guaranteed investment contracts Guaranteed investment contracts in the USEC Stable Value Fund are fully benefit responsive, as defined in the American Institute of Certified Public Accountants' Statement of Position 94-4, Reporting of Investment Contracts Held -------------------------------------- by Health and Welfare Benefit Plans and Defined Contribution Pension Plans. A - ----------------------------------------------------------------------------- fully benefit responsive investment contract provides a liquidity guarantee, by a financially responsible third party, of principal and previously accrued interest for liquidations, transfers, loans or hardship withdrawals initiated by plan participants exercising their rights to withdraw, borrow or transfer funds under the terms of the Plan. Investments in guaranteed investment contracts are stated at contract value, which represents the initial investment plus accumulated interest, plus earnings, less participant withdrawals and administrative expenses and approximates fair value. There are no valuation reserves recorded to adjust contract values. The crediting interest rates for contracts as of December 31, 2001 and 2000, ranged from 5.42 percent to 7.16 percent. The average stable value fund yield as of December 31, 2001 was 6.1 percent. These contracts' maturity dates range from February 28,2002 through August 2, 2004. Investment valuation and income recognition The Plan's fund investments are stated at fair value, based on quoted closing market prices, other than the USEC Stable Value Fund. Purchases and sales of investments are recorded on the trade date. Interest income is recorded on the accrual basis. Dividend income is recognized on the ex-dividend date. 7 The Plan presents in the statements of changes in net assets the net appreciation (depreciation) in the fair value of its investments, which consists of the realized gains or losses and the unrealized appreciation (depreciation) on those investments. Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions and deductions during the reporting period. Such estimates include those regarding fair value. Actual results could differ from those estimates. Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation. 3. Investments: The following table presents investments that represent 5 percent or more of the Plan's net assets on December 31, 2001 and 2000:

8 The Plan provides for investments in various forms of mutual funds, common stock and a stable value fund that holds individual guaranteed investment contracts. In general, investments are exposed to various risks, such as interest rate, credit, and overall market volatility risks. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statements of net assets available for benefits. 4. Tax status: The Plan has received a determination letter dated February 15, 2002, from the Internal Revenue Service (IRS) that the Plan is qualified to be exempt from federal income taxes under certain provisions of the Internal Revenue Code (IRC). Pursuant to such provisions, participants are not subject to federal income taxes on their contributions to the Plan, participating employer contributions to the Plan, or on income accruing to their accounts, until such time as they receive distributions from the Plan. Although the Plan has been amended since receiving the determination letter, the Plan administrator believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. 5. Related-party transactions: Certain Plan investments are shares of mutual funds managed by FMTC. FMTC is the Trustee as defined by the Plan and therefore, these transactions qualify as party-in-interest transactions. USEC as a Participating Employer is a related party. At December 31, 2001 and 2000, the Plan held an investment of 41,094 and 9,909 shares of USEC Inc. common stock, respectively. The fair market value of the common stock at December 31, 2001 and 2000 was $294,233 and $37,555, respectively. The dollar value of purchases and sales of USEC stock for the year ended December 31, 2001 was $2,771,568 and $2,491,869, respectively, and the dollar value of purchases and sales for the year ended December 31, 2000 was $119,952 and $88,764, respectively. 6. Subsequent events: The Plan was amended to eliminate the Lockheed Martin Stock Fund as an investment option. 9 USEC Savings Program Employer Identification Number 52-2107911, Plan Number 001 Schedule of assets (held at end of year) As of December 31, 2001 ERISA Form 5500 Schedule H, line 4(i)
