Kairos Power Installs Pilot Small Modular Reactor Vessel Fabricated in the UK

Strategic Insights -

The installation of a 14-foot-high pilot reactor vessel by American nuclear energy company Kairos Power marks a significant milestone in the construction of its third Engineering Test Unit (ETU 3.0), a non-nuclear reactor mock-up. The vessel was fabricated in the UK using Cambridge Vacuum Engineering (CVE) welding technology and is a crucial component in Kairos Power's plans to deploy advanced nuclear reactors in the US. The Engineering Test Unit program, supported by the US Department of Energy, aims to validate a safe and cost-effective pathway for future SMR deployment. The pilot involved innovative engineering techniques and construction processes leveraged through industry and academic partnerships.

Key Takeaways:

  • The installation of the reactor vessel is a significant milestone in the construction of ETU 3.0, a non-nuclear reactor mock-up, for Kairos Power's plans to deploy advanced nuclear reactors in the US.
  • The vessel was fabricated in the UK using Cambridge Vacuum Engineering (CVE) welding technology, specifically electron beam welding, which produces high-quality welds at least an order of magnitude faster than conventional arc welding.
  • The integration of advanced manufacturing technologies by the University of Sheffield Advanced Manufacturing Research Centre (AMRC) enabled the fabrication of the complete vessel rather than individual parts, proactively addressing potential future issues.
  • The ETU 3.0 project allowed Kairos Power to evaluate the use of electron beam welding to enable faster, more cost-effective production of reactor vessels with precise tolerances for its future commercial fleet.
  • The collaboration between Kairos Power, CVE, and the AMRC accelerated the deployment of advanced nuclear technologies for clean, affordable, and secure power.
  • The partnership between the University of Sheffield AMRC and Cambridge Vacuum Engineering demonstrates the transformative potential of electron beam welding in advanced manufacturing, particularly in nuclear construction.
  • Kairos Power's goal is to lower costs and accelerate production timelines for a future commercial fleet of SMRs that will support the clean energy transition in the US.
  • Craig Gerardi, VP manufacturing at Kairos Power, emphasized the importance of collaborating with CVE and AMRC to gain hands-on experience with electron beam welding and transform reactor delivery.
  • Ben Morgan, interim CEO at the University of Sheffield AMRC, highlighted the significance of large demonstrators like the ETU 3.0 reactor vessel in bringing advanced manufacturing methods into industry.
  • Bob Nicolson, CVE managing director, underscored the technological advancements and commercialization potential of electron beam welding in SMR deployment.

Statistics:

  • The reactor vessel is 14 feet high.
  • Electron beam welding produces high-quality welds at least an order of magnitude faster than conventional arc welding.
  • Welds that previously took a week for the ETU 2.0 unit were completed in 10 minutes for ETU 3.0.
  • The fabrication of the complete vessel rather than individual parts enabled the project to proactively address potential future issues.
