Andrew Buchan

Dr. Andrew Buchan is an Honorary Lecturer in the Department of Earth Science and Engineering at Imperial College London, affiliated with the Faculty of Engineering. His research focuses on advanced computational methods for nuclear systems, including neutron transport modeling and multi-phase fluid flow simulations. He leads the development of codes like FETCH and RADIANT, emphasizing adaptive finite elements, reduced order models, and uncertainty quantification.

Education:

• PhD in Nuclear Engineering, Imperial College London (2002–2006)

Research Interests:

• Simulation of coupled neutron transport and fluid dynamics in nuclear reactors
• Development of novel numerical methods (e.g., spherical wavelets, Krylov solvers)
• Historical criticality accident analysis and reactor safety modeling
• Integration of AI/ML techniques for improved computational efficiency

Grant Coordination: Scientific coordinator of a major grant to design the RADIANT radiation transport model.

Labs/Teams: Active in the Applied Modelling and Computation Group at Imperial College.
