Dounreay Site Restoration Limited

GERMANTOWN, Md.; March 10, 2021 –Amentum is delighted to announce that our team has been successful in securing the Prototype Fast Reactor (PFR) Intermediate Level Waste (ILW) Size Reduction Facility Concept Design contract procured by Dounreay Site Restoration Limited (DSRL), in Thurso, Caithness, Scotland.

The challenge to size-reduce the PFR ILW has been met by a solution that brings project management expertise from Amentum, first-hand in-depth knowledge of the PFR ILW challenge at Dounreay and extensive experience from relevant international and domestic projects. This includes size reduction of the Sodium Cooled Reactor at the Karlsruhe site in Germany, the Modular ILW Encapsulation Plant (MILWEP) across Magnox sites, as well as lessons learned from more than 25 international projects of relevant scope. This solid foundation of knowledge enables us to bring delivery confidence and a value for money solution to DSRL that is based on an effective and proven solution.

“We are very pleased to have been selected to deliver this initial phase of the PFR ILW Size Reduction Facility for DSRL”, said David Batters, Senior Vice President of Amentum in the United Kingdom. “The concept design study will allow our highly capable team to showcase our international expertise and bring forward opportunities to present the best possible concept to our client. Work is already underway, and we continue to be fully committed to the safe decommissioning of Dounreay.”

The contract is tendered under the Dounreay Decommissioning Services & Works Framework, a seven-year framework with expected scope of £400m. The Amentum-led team has brought best athlete in play for this contract, including Westinghouse, NSG Environmental, Abbot Risk Consulting (ARC), DBD, Exyte Hargreaves and AECOM. We work with a dedicated supply team and directly with the Dounreay team to ensure that an integrated approach is undertaken for this important scope of work. Work on the project commenced in October and is scheduled to conclude by September 2021.
