Transaction Is the Right Choice for Stockholders

Transaction Is the Right Choice

Certain Value NOW with Transaction

• The offer from EnergySolutions is highly attractive

• Transaction provides certain value

• Closing expected in June 2006

VERSUS

Uncertain Value from Standalone Operations

• Challenges to maintaining and growing revenues

• Financial results demonstrate volatility and risk

• Revenue diversification untested

NO Alternative Offer Has Materialized.

Uncertain Value

Challenges in Federal Services businesses have intensified:

• Fernald contract ends in 2006

• No significant new projects to offset Fernald have been awarded

• Major DOE procurements continue to experience delays

• Small business contractors are increasingly competitive for many opportunities

Challenges in Commercial Services are increasing:

• Big Rock Point decontamination and decommissioning (D&D) contract ends in 2006

• No large D&D contracts are on the drawing board

• Plant life and licensing extension is resulting in fewer, smaller contract opportunities

• Increased competition from a wider range of parties, including EnergySolutions

Potential for New Nuclear Plants Provides NO Benefit to current business for Many Years

Duratek’s efforts to diversify abroad and into other nuclear service areas is untested

• Duratek has limited experience winning and performing on projects in its new service offerings

• Overseas awards are competitive and marked by uncertain procurement processes

Recent financial results demonstrate risk

• Financial operating results often fluctuate significantly – compare Q3 05 to Q3 04

Duratek will continue to incur added costs and inefficiencies of being a small cap public company

Certain Value

Transaction provides certain value with minimal risk

• All financing is committed

• HSR waiting period is over and all regulatory approvals required for closing the merger have been obtained

• Transaction can close promptly after stockholder vote in June 2006

• Duratek has received NO alternative proposals since the merger agreement was signed and announced on February 7, 2006

• The merger offers a significant premium to pre-announcement trading values

• Voting down the merger will almost certainly result in a significant decrease in the trading price - Stock was trading at $17.50 on the day prior to the announcement

The EnergySolutions offer is highly attractive

• $22.00 merger price represents a 25.7% premium to $17.50 trading price on date preceding merger announcement and 36.7% premium over 90-day average trading price of $16.09

• Higher market prices in winter 2004/2005 reflected unusually strong Q3 2004 results that have not recurred and preceded adverse trends that emerged in 2005

• Price represents significant value and an attractive multiple especially given Duratek’s projection of low growth

A viable alternative offer is unlikely to materialize

• Teaming arrangements and other long-time relationships with key industry players have not resulted in other definitive acquisition proposals for the Company

• A thorough market check as recently as 2002 yielded no strategic acquiror interest

• No acquirer, other than EnergySolutions, has made a definitive proposal for Duratek in the past several years

EnergySolutions is a unique buyer, paying a strategic premium

• EnergySolutions has a strong strategic interest in Duratek

• EnergySolutions is in a strong financial position

• EnergySolutions has a willingness and ability to fully value the Company

• An open process of seeking other potential buyers would not likely result in a better offer and would not ensure obtaining the best price from EnergySolutions

• Board believes process undertaken achieved the best acquisition price available for Duratek stockholders

A Vote FOR the EnergySolutions Transaction is a vote FOR Certain Value

A Vote AGAINST the EnergySolutions Transaction is a vote for an Uncertain Future with Significant Downside Risk

VOTE FOR THE TRANSACTION AND FOR $22.00 PER SHARE IN JUNE 2006
