SEPARATION AGREEMENT

EnergySolutions, Inc., a Delaware corporation (the “Company”), and Val John Christensen (“Executive”) have entered into this Separation Agreement (this “Separation Agreement”) on June 10, 2012.

RECITALS

A.            Executive and the Company previously entered into an Executive Severance Agreement, dated as of November 4, 2011 (the “Executive Severance Agreement”).

B.            The parties desire to enter into this Separation Agreement in order to (i) establish the terms of Executive’s separation from service with the Company, (ii) confirm the payments and benefits to which Executive is entitled under the Executive Severance Agreement as a result of Executive’s separation from service with the Company, and (iii) confirm Executive’s obligations to the Company pursuant to the Executive Severance Agreement following Executive’s separation from service with the Company.

NOW THEREFORE, in consideration of the mutual promises contained in this Separation Agreement, the parties agree as follows:

1.             Termination of Employment.

(a)                                  As of 11:59 pm, Mountain Time, on June 10, 2012 (the “Termination Date”), Executive’s employment with the Company will terminate.  As of the Termination Date, Executive resigns all positions Executive holds as an officer, director or employee of the Company and its subsidiaries and affiliates, and will promptly execute such documents and take such actions as may be necessary or reasonably requested by the Company to effect or memorialize the resignation of such positions.  Executive’s termination of employment as of the Termination Date will be considered a termination by the Company without Cause (as such term is defined in the Executive Severance Agreement).

(b)                                 Executive’s termination pursuant to Section 1(a) will be a “separation from service,” as defined in Section 409A of the Internal Revenue Code of 1986, as amended, and the regulations and official guidance issued thereunder (“Section 409A”).

2.             Payments and Other Consideration.  In accordance with the terms of the Executive Severance Agreement, subject to the terms and conditions thereof (including, without limitation, Executive’s compliance with Sections 3 and 6 hereof), Executive is entitled to receive:

(a)                                  all Accrued Obligations (as such term is defined in the Executive Severance Agreement);

(b)                                 a lump sum cash amount equal to the Pro Rata Bonus (as such term is defined in the Executive Severance Agreement), payable at the later of (i) within 30 calendar days after a determination of the actual bonus is made by the Compensation Committee of the Board of Directors of the Company (the “Committee”) or other appropriate body, as provided in the Company’s Annual Incentive Plan or comparable arrangement for the year in which the termination occurs, but not later than March 15, 2013, and (ii) the “Six Month Deferral Date” (as such term is defined in the Executive Severance Agreement);

(c)                                  an aggregate cash amount equal to $3 million in respect of severance pay equal to Executive’s current monthly Base Salary (as such term is defined in the Executive Severance Agreement) plus Executive’s current Target Bonus (as such term is defined in the Executive Severance Agreement) for 24 months from the Termination Date, with such aggregate amount divided into equal monthly portions and payable in accordance with the Company’s regular pay practices; provided that any severance payment installments will be suspended for the period prior to the Six Month Deferral Date and paid in arrears on the Six Month Deferral Date;

(d)                                 in respect of the Welfare Benefit Continuation (as such term is defined in the Executive Severance Agreement), provided Executive elects coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), the Company will pay or reimburse Executive for such premiums (each as in effect on the Termination Date) until the earlier of (i) the 24-month anniversary of the Termination Date and (ii) the date Executive has commenced new employment and has thereby become eligible for health benefits from another employer;

(e)                                  the provision of professional outplacement services in accordance with the Executive Severance Agreement for up to one year following the Termination Date;

(f)                                    notwithstanding anything to the contrary in any applicable equity plan or award agreement, each equity award that is held by Executive and outstanding as of the Termination Date will otherwise continue to vest in accordance with its terms through the date of the termination of the Consulting Agreement (the “Consulting End Date”);

(g)                                 notwithstanding anything to the contrary in any applicable equity plan or award agreement, each option to acquire shares of the Company’s common stock that is held by Executive and vested and outstanding as of the Termination Date will remain outstanding and exercisable for 90 days following the Consulting End Date (but in no event later than the date of expiration of the original term of such option); and

(h)                                 notwithstanding anything to the contrary in any applicable equity plan or award agreement, any outstanding performance share units granted to

2

Executive by the Company, the performance periods for which have not been completed as of the Consulting End Date, will vest and be payable to Executive in accordance with the terms thereof, except that such awards will only vest on a pro rata basis (determined by dividing (i) the number of years in the applicable performance period that elapsed through the end of the year in which the Consulting End Date occurs by (ii) the total number of years in the applicable performance period), subject to the achievement of the applicable pro rata performance goals (determined in the case of each applicable performance goal by dividing (A) the actual achievement with respect to the performance goal through the end of the year in which the Consulting End Date occurs by (B) the applicable performance target(s) in respect of the entire original performance period),

in each case (other than Sections 1(f), (g) and (h) hereof) paid or provided as set forth in, and subject to the terms and conditions of, the Executive Severance Agreement (together, the “Severance Benefits”), but subject in all events to Section 16 hereof.  The Severance Payments will be in complete satisfaction of any and all compensation, severance or other benefits otherwise due to Executive upon termination of employment (including, without limitation, any amounts otherwise payable under the Executive Severance Agreement).

3.             General Release Agreement.  As contemplated by the Executive Severance Agreement, as a condition to the receipt of the Severance Benefits, Executive must first execute and deliver to the Company (and, if applicable, not revoke) the General Release Agreement attached hereto as Exhibit A (the “Release”), which Release will constitute a part of this Separation Agreement.

4.             Affirmations.  Executive affirms that Executive has not filed or caused to be filed, and is not presently a party to any claim, complaint or action against the Company or any of its subsidiaries or affiliates in any forum.  Executive also affirms that Executive has no known workplace injuries or occupational diseases, and has been provided and has not been denied any leave requested under the Family and Medical Leave Act.  Executive disclaims and waives any right of reinstatement with the Company or any of its subsidiaries or affiliates.

5.             Benefits and COBRA.  Executive has ceased all Company health benefit coverage and other benefit coverage.  Executive acknowledges that the Company has advised Executive that, pursuant to COBRA, Executive has a right to elect continued coverage under the Company’s group health plan for a period of 18 months, or such longer period as permitted under applicable law, from the Termination Date.

6.             Restrictive Covenants.  Executive acknowledges and agrees that any and all of Executive’s obligations and restrictive covenants contained in the Executive Severance Agreement will continue in effect in accordance with the terms and conditions thereof.

12.           Severability.  If any provision of this Separation Agreement is declared or determined by any court of competent jurisdiction to be illegal, invalid or unenforceable, the legality, validity and enforceability of the remaining parts, terms or provisions will not be affected thereby, and said illegal, unenforceable or invalid part, term or provision will be deemed not to be part of this Separation Agreement.
