He has worked closely with UK Government on supporting policy such as Keeping the Nuclear Option Open and progressing towards new nuclear build.

Dr Kevin Horsburgh

National Oceanography Centre

Dr Kevin Horsburgh is an expert in the physics and computer modelling of tides, storm surges and tsunamis and in the statistical analysis of sea level and its extremes. He is head of the Marine Physics and Ocean Climate research group at the National Oceanography Centre. He has responsibility for providing advice to policy-makers, planners and coastal engineers on the impacts of sea level rise and increases in coastal flood risk. He has published over 50 refereed journal articles on many aspects of shelf sea physics. Internationally, he is a member of the Intergovernmental Oceanographic Commission (IOC) and World Meteorological Organisation (WMO) expert team on waves and storm surges where he works closely with delegates from other nations to improve the global understanding of waves and storm surge climate. He is an also a member of the IOC task team on global tsunami warning systems.

John Earp


A Fellow of both the Institution of Mechanical Engineers and the Nuclear Institute Johns career began as a mechanical apprentice with the Central Electricity Generating Board (CEGB) in 1964 and progressed to the role of Generation Manager with British Energy from which he retired in 2001. He undertook various tasks associated with AGR, Magnox, PWR and BWR reactors the latter two whilst working in the USA.

Since retiring, he established a consultancy supporting companies to review their nuclear strategy in a declining market focused on decommissioning. During this period, he also assisted the setting up of the Nuclear Decommissioning Authority (NDA). Given the current renewed interest in nuclear, he currently assists companies and organisations to develop strategies to suit the new vibrant market. Through out this period John has accumulated more than 35 years of broad nuclear experience.

Mark Gorry

Safety & Technical Director

Mark joined the Central Electricity Generating Board (CEGB) in 1975 as a Technician Apprentice and graduated in 1981 from the University of Aston under the Professional Engineer Training Scheme (honours degree). Mark worked in various operations and engineering positions at Heysham 1, Wylfa, and Heysham 2 power stations. Mark became Human Resources Manager in 1995, then Technical and Safety Manager and later Engineering Manager in 1997. Since 2001, he has been Station Director of Dungeness B, Sizewell B, Heysham 1 and Hunterston B power stations. He was appointed Safety & Technical Director on 10 July 2009. Mark holds an honours degree in Energy Technology (Power Engineering), an MBA, and is a Chartered Engineer. He is a Fellow of both the Institution of Engineering & Technology and the Institution of Nuclear Engineers.

Dr Anastasios M Zodiates

Radiation Protection Consultant

Dr Zodiates has 25 years experience in the nuclear industry in the areas of station operations, design and construction of nuclear stations, safety case development, and support of operating nuclear stations. His main area of expertise is Radiation Protection and Radiological Consequences Analysis. He is a Radiation Protection Consultant to the International Labour Organisation (ILO).

He is nominated to the Technical Advisory Panel by Prospect Trades Union. He is a Union Representative at EDF Energy and is a member of Prospect National Executive Committee (NEC).

He has a degree in Electrical Engineering, an MSc in Reactor Physics and Engineering and a PhD in Physics

Edmund Booth

Eurocode 8

Nominated by the Royal Academy of Engineering Edmund Booth is a structural engineer who since 1995 has worked as an independent consultant. Since 1980, he has specialised mainly in the design, analysis and assessment of earthquake resistant structures, and has been involved in the seismic qualification of many nuclear related facilities in the UK. He is the UK national technical contact for the European seismic code of practice, Eurocode 8. He is a founder member of the UK's Earthquake Engineering Field Investigation Team, and has visited the sites of seven damaging earthquakes. He is author of the second edition of the textbook Earthquake Design Practice for Buildings. Edmund was elected a fellow of the Royal Academy of Engineering in 2010.

Dr James Gemmill

Scottish Environment Protection Agency

Dr Gemmill has worked as a regulator in Scottish Environment Protection Agency since 1996 covering both conventional and radioactive issues. He is currently SEPAs head of radioactive substances Policy and Regulation and was previously a radioactive substances inspector and nuclear site regulator for SEPA. He has also spent 5 years as general pollution manager covering southwest Scotland.

He has over 20 years experience in the field of Radioactive Substances, covering use, disposal, health protection, measurement, assessment, modelling and regulation. He has dealt with most aspects of radioactive materials use, including medical, scientific, industrial, off shore, and nuclear. Prior to joining SEPA he worked for both the National Radiological Protection Board and then for Strathclyde Regional Chemist where he managed a radiochemistry laboratory.

He has considerable experience in environmental monitoring and emergency arrangements.

Robin Grimes

Imperial College
