Role description

The Company

Thomas Thor are working in an exclusive partnership with newcleo to support their UK operational expansion and create the senior structure of their technical delivery team.

Privately funded and headquartered in London, newcleo was launched in 2021 to be a disruptor in the field of nuclear energy. Its mission is to generate safe, clean, economic and practically inexhaustible energy for the world, through a radically innovative combination of existing, accessible technologies. With visionary co-founders, newcleo capitalises on thirty years of R&D activity in metal-cooled fast reactors and liquid-lead cooling systems, and our senior management and advisory team can boast hundreds of years in cumulative hands-on experience.

newcleo’s technology, mostly comprising a novel approach to already qualified solutions, addresses equally well the three challenges affecting the nuclear industry to date: waste, safety and cost.

  • Waste:Our fast reactors are capable of efficient “burning” (i.e., fission) of depleted uranium, plutonium and Minor Actinides. When operated with MOX fuel generated from reprocessed nuclear waste, our reactors not only ensure sustainability by closing the fuel cycle, but can also boost energy independence
  • Safety: Our lead-cooled reactors operate at atmospheric pressure. The properties of lead (thermal capacity and conductivity, boiling point, chemically inert, low neutron activation, shielding properties) together with newcleo’s passive safety systems ensure very high levels of safety
  • Cost: Our reactor design has been optimised over the last 20 years leading to the concept of an ultra-compact and transportable 200MWe modules with improvements in energy density compared to other technologies. Costs are kept low by means of simplicity, compactness, modularity, atmospheric pressure operation and elevated output temperature.

In the UK, newcleo’s immediate focus is on delivering a prototype 30MWe LFR by 2030 followed by an initial battery of 4-6 x 200MWe reactors with deployment planned for the early 2030s. We are also considering options for the manufacture and supply of MOX fuel. We are building our team to meet this challenging and exciting objective.

The Role

A fundamental aspect of newcleo’s mission is to close the fuel cycle, utilising MOX fuel generated from nuclear waste. The post holder will lead newcleo’s UK programme of innovation and development in this area with the aim of re-purposing UK nuclear materials to fuel newcleo’s UK LFR fleet and to utilise the the Pu burning capabilities of fast reactor technologies. Ultimately, we intend to fund and build a MOX manufacturing facility at a suitable site in the UK (e.g. Sellafield).

You will build strong relationships with key government and industry stakeholders to assess feasibility, influence policy and work seamlessly with colleagues in UK, France and Turin to identify and realise the optimum strategy and delivery approach in line with principles of safety, affordability, deliverability and in line with all UK regulatory requirements.


  • Establish and lead newcleo’s fuel cycle programme in the UK including feasibility studies, strategic optioneering/ concept design, implementation and handover.
  • Build strong relationships with the UK Nuclear Decommissioning Authority (NDA) and its group companies and manage any studies to evaluate technical, commercial and regulatory feasibility of using MOX fuel in newcleo’s UK prototype and subsequent 300MWe modules, and into the access and use of nuclear materials already in the UK for this purpose.
  • Establish robust supply chain partnerships and industrial collaborations to ensure delivery success.
  • Engage with relevant industry stakeholders to influence policy and decision making.
  • Lead by example on international collaboration, knowledge sharing and team working with colleagues across UK, Italy and France.
  • Contribute to building newcleo’s overall UK business case.
  • Play a key role as part of the UK leadership team.


  • Proven delivery experience/ senior operating experience across the nuclear fuel cycle with practical experience and credibility.
  • Excellent technical understand of nuclear fuel cycle, processing/ handling of nuclear materials and fuel fabrication.
  • Strong UK regulatory and policy context.
  • Bachelor’s degree as a minimum in an appropriate technical field (Chartered Engineer).
  • Willingness to travel nationally and internationally as part of the role.

6+ years’ experience in international technical recruitment. Enjoy working on senior level technical roles that prove challenging to fill. Specialized in the nuclear industry – new build projects, having a particular interest in advanced nuclear technology. Focused on building strong relationships with candidates and clients to ensure a positive candidate experience and effective account management.
