About the Opportunity

Amentum is the Design and Engineering partner for Sellafield under the PPP (Programme and Project Partners). This is a 20-year arrangement to deliver ~£7bn of major projects. We are looking to recruit high value expertise from across regulated and comparable sectors to work in a collaborative environment. PPP is delivering major projects, site wide improvements and provision of supporting services.

The Project 

The Sludge Handling and Export Plant (SH&EP) will treat sludge, originating from one of the highest hazard facilities at Sellafield, into a form suitable for long-term storage and disposal.  SH&EP is currently in the early stages of project development. 

The project involves both 'wet process' and mechanical handling/movement systems.  The facility design needs to achieve high plant availability, so the application of Total Productive Maintenance (TPM) principles is key.  Challenges associated with the facility location drive the requirement for modularised build techniques and Modern Methods of Construction.  As a new facility, sustainability features highly within the design considerations.
