Leading global consulting, construction engineering and operating firm Egis has been appointed to support EDF Energy in the delivery of Sizewell C project to plan, design and build two European Pressure Reactors located on the east coast of Suffolk in UK. As lead design engineer of the ‘ICOSH consortium’ made up of Jacobs UK, SETEC TPI and Tractebel Engineering, Egis and its partners will deliver the civil detailed designs for the nuclear island which is the ‘heart’ of the power plant, including the reactor, fuel and safeguarding buildings. These buildings are the most complex and important structures that will be built on the nuclear island, needing to meet extremely high safety and safeguarding standards. Egis has supported Sizewell C since 2020, creating replication studies of the nuclear island buildings at Hinkley Point C to use at Sizewell C, and geo-technical studies to define the soil-structure interaction. Sizewell C will include two new state-of-the-art EPRs that wherever possible, will be replica designs developed during the construction of the sister plant, Hinkley Point C, where Egis was also appointed to deliver the civil engineering designs and the geotechnical studies. The use of a standardised design is the optimum method of reducing construction and operational risk – supporting the UK to bring more nuclear power projects in future. When complete, Sizewell C will be capable of powering six million homes, equivalent to 7% of the UK’s energy needs and will generate electricity for 60 years. The project is thought to be pivotal in helping the UK meet its net zero targets by 2050 and will provide a vital boost to the country’s energy security.
