Laboratory Fellows

Steve Graham was appointed as Laboratory Fellow in 2013, covering the area of Engineering Modelling in the Laboratory. Steve has a long career in fluid flow and heat transfer simulation, involving the pragmatic use of a variety of modelling approaches to deliver insight into the behaviour of complex nuclear systems, primarily for use in safety cases. His specific technical discipline is Computational Fluid Dynamics (CFD). Through his work Steve developed a heat transfer model to provide key input into the Windscale Pile 1 decommissioning safety case, which enabled the damaged fuel channels to be inspected for the first time in 50 years since the fire incident in 1957. The project team responsible for delivering this work won a UKAEA award in 2005.

He has provided key input into international initiatives on quality and trust in modelling and represented BNFL in the Fifth Framework project QNET-CFD, where best practice guidelines were produced for industrial practitioners. He has recently been invited onto a TSBSpecial Interest Group on Uncertainty Quantification and Management in modelling.

Steve is a visiting Research Fellow at the University of Leeds and provides input to the External Advisory Boards in Mathematics and Physics at the University. He is the industrial supervisor for a number of postgraduate students at the Universities of LeedsLiverpool andManchester.

Steve has been interested in bringing people in the Modelling arena together and was appointed to set up the Sellafield Ltd Centre of Expertise on Modelling and Simulation. Steve also chairs the NNL Modelling and Simulation Working Group.
