Context and challenges
Sellafield Ltd, a major player in the nuclear industry in the United Kingdom, is responsible for the safe and secure operation and clean-up of the Sellafield nuclear site. It now comprises 400 buildings spread over 10 sqm and employs around 10,000 people.
The DSA (Design Services Alliance) framework agreement, won by a joint-venture, is a multi-disciplinary design and safety contract focused on hazard reduction and decommissioning for the Sellafield site in West Cumbria, United Kingdom.
This joint-venture has appointed Assystem (25% partner), which was tasked with developing a completely new approach for the delivery of engineering, design and safety case assessment services in support of Sellafield’s operations. Assystem, together with their partners in the joint-venture, have been engaged to deliver a step-change improvement in safe, efficient, site-focused design services through collaborative working, aligned objectives and stakeholder accountability.
The programme is structured across eight lots over four capability areas, including mechanical handling; process plant; control, electrical and instrumentation (CE&I); and civil, structural and architectural (CS&A) systems.
Individual projects include:
Dragon Waste Project, Long Term Periodic Reviews, First Generation Magnox Storage Pond, SPP1 BSV Vessel Monitoring, Vitrified Residue Returns, Concrete Lined Drums, Site Ion Exchange Effluent Plant (SIXEP – includes use of BIM 21st century tools), major projects RAP (Replacement Analytical Project), SCP (SIXEP Contingency Plant) and SRP (SPRS Retreatment Plant).
