Fuel Cycle Technology Leader

Bio

Key Roles:

  • Fuel Cycle Technology R&D Leader

  • Deputy Director, GAIN (Gateway for Accelerated Innovation in Nuclear)

  • UK Country Co-ordinator, DOE Office of Nuclear Energy

Andrew has nearly 25 years of professional experience in the United Kingdom and the United States working and leading in the fields of reactor physics, fuel and core design, plutonium disposition, fuel development and fuel cycle analysis (technical, economics, and safeguards).

Andrew is the senior leader responsible for providing technical leadership, coordination and integration for the numerous and diverse nuclear energy related fuel cycle R&D activities within the division consistent with existing programmatic missions and emerging opportunities.

His fuel cycle R&D leadership areas of responsibility include nuclear fuel cycle systems analyses for open, limited recycle (such as MOX fuel cycles) and closed fuel cycles, actinide transmutation in thermal and fast reactors and externally driven systems, evaluation of uranium, plutonium and thorium fuel cycles, fuel resources, fuel manufacturing, materials recovery, materials safeguards and security, used fuel management and disposition, and waste forms.

He is a delivery-focused Nuclear Engineer with demonstrated expertise and experience in performing, managing and leading international, multi-disciplinary and multi-agency projects and programs for a range of sponsors in the US and the UK.

Andrew has an extensive track record of working with a range of stakeholders, including sponsors, senior managers, government agencies, universities, regulators, and industry, both domestically and internationally. Experienced in initiating, leading and delivering on multi-organizational and multi-national programs, and is an effective communicator and collaborator.

Andrew is a recognized strategist, able to make complex arguments (technical and strategic) understood by a range of stakeholders and aid/lead them through the decision making process.

He is a Chartered Physicist (CPhys), a Fellow of the Institute of Physics (FInstP), and formerly a Royal Academy of Engineering Professor of Nuclear Engineering in the UK.

In December 2014 the US Department of Energy appointed Andrew as the Laboratory Lead Coordinator for nuclear energy research programs between the US and the UK.

Specialties include:

  • Nuclear programme management
  • Technical leadership and management
  • Strategist
  • PWR safety and performance and analysis
  • Plutonium management and strategy
