Alion Awarded Two Contracts to help Korean Hydro and Nuclear Power Meet Nuclear Safety Requirements

Technology Solutions Company to Perform Hydraulic and Structural Analysis and Develop Qualification Reports

McLean, VA – March 29, 2012 – In nuclear plants, ensuring that safety systems can operate under the stress of an accident or natural disaster is crucial. The cooling system depends on “sump strainers,” which filter debris from the water that cools the reactor. Alion Science and Technology, an employee-owned engineering, R&D, IT and operational solutions company, has won two contracts to perform both hydraulic and structural analysis on replacement sump strainers at eight Korean nuclear units for Korean Hydro and Nuclear Power (KHNP).

Working under subcontract to Transco Products Inc. (TPI), a U.S. company, who is providing the new sump strainers to KHNP, Alion will perform the necessary testing and analysis at its Illinois facilities to qualify the strainers for hydraulic and structural performance. The strainers must be tested and qualified to make certain that they can effectively filter cooling water that must be recirculated within the containment, stand up to the associated hydraulic pressure and survive an earthquake.

Upon completion of the analyses, Alion will deliver a qualification report that documents the strainer performance parameters and design basis.

“Sump strainers must adequately strain debris from cooling water and be able to withstand the loads from operation and seismic events. Alion’s engineers will assure that they will perform as intended if a design-basis accident occurs,” said Chris Amos, Alion Senior Vice President and Manager of the Technology Solutions Group. “This project builds upon Alion’s deep experience with nuclear power plant safety and further expands our presence in global markets.”

The structural analysis contract will run until Jan. 20, 2013 and the hydraulic contract will run until Sept. 30, 2012.
