The first new nuclear power station in the UK for a generation is being built at Hinkley Point C in Somerset, and TWI Ltd has been offering specialist assistance to contractor and Industrial Member company, Darchem Engineering Ltd. Whilst the construction of the first permanent structures is under way, the UK supply chain is active with bidding (and winning) contracts for the manufacturing of various nuclear plant components.
Darchem (based in Stillington), has recently been awarded a fabrication contract that involves material procurement, welding, fabrication and testing. All of these and other related activities are to be carried out in accordance with the Afcen RCC-M Code.
TWI has been assisting Darchem through the tendering stage and this has continued into the first phase of the contract, when a significant volume of documentation had to be prepared and submitted for approval before production could commence. Darchem has been working closely with their customer, but has found TWI specialist assistance helpful. All contracts on Hinkley Point need to be right the first time and thorough preparation is key.
Soon after the contract started, TWI’s Marcello Consonni, an experienced welding engineer and member of various international standard committees, gave a one-day bespoke workshop at Darchem’s site. This provided an overview of the RCC-M code and the practical aspects of its application. As part of the workshop, Marcello and Darchem’s project team went through the code and the contractual requirements. Together they addressed the most urgent and complex technical requirements and ironed out potential conflicts. Following the workshop, TWI issued a report with an overview of the applicable code requirements and recommended immediate actions.
As a TWI Industrial Member, Darchem continue to have access and support on welding, quality assurance, quality control and non-destructive testing throughout the project, especially as this enters the manufacturing phase.
Darchem Engineering is a wholly owned subsidiary of Esterline Technologies based in USA. Darchem has sales of over £70M, employing over 800 people split between two sites located at Stillington in the North East of England and Gloucester.
