Registration is closed
Technical Group Event


During this meeting we will be covering the future opportunities for SMR/AMR manufacture, the design, materials and manufacturing challenges of advanced modular reactors and some of the advances in welding, NDE and cladding of vessels, ending with a presentation on the standards that are most likely to be implemented in SMR/AMR manufacture. 

Experts from industry and TWI Ltd will be presenting on a range of topics:

Keynote Speaker:

  • John McGloin, Head of Procurement - Partnerships, RR SMR, on Rolls-Royce SMR – Engaging Our Supply Chain

The presentation will give an overview of Rolls Royce SMR and their approach as well as how they see Rolls Royce SMR's place in the clean energy space; going on to explain how they'll use their supply chain to achieve it. 

  • Chris Hankinson, Head of Engineering, MoltexFLEX on AMRs – Design and Manufacture

The presentation will cover the market position and benefits of the FLEX design, timeframes and approach to delivery and technical challenges ahead, and how these will be addressed. 

  • Chris Punshon CEng FWeldI, Head of New Energy Applications, Cambridge Vacuum Engineering on Electron Beam Welding of Vessels for Nuclear Applications

The presentation will cover the exploitation of electron beam welding in nuclear power generation applications, an update on new developments in the electron beam systems leading to potential quality and production benefits in the fabrication of nuclear power plant.

  • Thomas Dutilleul, Nuclear AMRC on Development of the Slope out Procedure for the Termination of Circumferential Welds.
The presentation will cover the development of the EB slope out procedure. This will be evidenced from both weld sectioning and NDE processes based on ASME requirements. Final deployment of the procedures has been based on scaled (2/3 scale) demonstrators (lower assembly based on an SMR RPV design).

  • Marcello Consonni, Consultant Welding Engineer, TWI Ltd on Overview of Welding Standards for Nuclear Vessel Manufacture - ASME III and IX

The presentation will provide an overview of the main standards and specifications applicable to pressure vessel for Small Modular Reactors’ nuclear islands, with emphasis on fabrication and welding qualifications.

  • Pallav Chattopadhyay, Director Consumables R&D&I EMEA, Lincoln Electric Deutschland GmbH on Developments in Electro Slag Cladding

The presentation will cover introduction of strip cladding processes and their applications; comparison and benefits over other processes; single layer and multi-layer cladding operations; selection of welding consumables for specific applications; hybrid electro slag cladding – development, main features, results and real life applications.
