Prof.
Paul Smith

Paul Smith has 46 years’ experience as a mathematical modeller, including 39 years in the nuclear industry. 

 

For over 20 years Paul has been involved in the modelling of radiation transport. Initially he developed models for post-closure criticality in geological disposal facilities for nuclear waste and validated models by comparison with measured data from the Oklo natural reactors that operated in western Africa two billion years ago. Since 2006 Paul has been the manager/ technical director of the ANSWERS software service, developing software for reactor physics, criticality and shielding for the nuclear industry worldwide. In particular he has been involved in the application of data assimilation to radiation transport to reduce uncertainty associated with predictive models.

Paul is currently a visiting professor in the Applied Modelling and Computation Group (AMCG) at Imperial College London and also in the Nuclear Futures Institute at Bangor University. 

 

Paul also has extensive experience of aerosol physics and its application to the dispersion of airborne contaminants, including radioactive isotopes and viruses (e.g. COVID-19), in both indoor and outdoor environments. He spent many years developing models of severe accident phenomena  in nuclear reactors, including the UK’s Magnox and AGR nuclear reactors, and contributed to the development of severe accident management guidelines for these reactors.
