The safety case of a nuclear reactor has traditionally been based on a deterministic safety assessment with little consideration of the risk (i.e. likelihood and consequences) of accidents. Since the 1970s, the use of probabilistic safety assessment as a supplement to deterministic assessments has increased throughout society, but particularly in relation to safety management in the nuclear industry.

This presentation will discuss the history of deterministic safety assessment of nuclear reactors and the ongoing movement towards a more risk-based approach, within the industry generally and at OPAL specifically. Deterministic safety concepts and the use of probabilistic safety assessment will be presented using the OPAL safety case as an example. The relationship between modern risk assessment and risk management methodologies and the existing safety case for a nuclear reactor will also be discussed.

About Mark Summerfield
Mark Summerfield was born in England and studied Nuclear Engineering at Manchester University, 1979-83. He then worked for NNC Ltd (now AMEC Nuclear), employed principally as a Systems and Safety Engineer on requirements for nuclear safety, the presentation of safety submissions to the UK regulatory authorities and the preparation of normal and post-fault operating procedures. He also contributed to a number of international projects in Russia and Eastern Europe.

He came to Australia in 1998 to join ANSTO, working in the Systems Safety and Reliability Section inter alia on the Application for the Site Licence and Tender for OPAL. He was seconded to INVAP in Argentina to assist in the preparation of the OPAL Preliminary Safety Analysis Report. On return to Australia, he joined the Project Management Core Team as Safety and Licensing Manager, interfacing with ARPANSA. He is now Leader, Technical Support Group, in the senior management team of ANSTO Nuclear Operations Division.

He is Chair of ANSTO Reactor Assessment Committee, a member of the ANSTO Safety Assurance Committee, ANSTO representative on the International Group of Research Reactors Steering Committee and a member of the IAEA-ANSN Regional Advisory Safety Committee for Research Reactors in the Asia Pacific Region.

David graduated from the University of NSW with a BSc and has over 35 years’ experience in analytical chemistry. He was initially employed by ESSO, where he worked in the Exploration Division Palaeontology and Geochemistry laboratories before moving to Petroleum Products in various quality assurance positions becoming Chief Chemist Australia in 1986. He joined ANSTO in 1988 as Laboratory Manager for the Environmental Chemical Analytical Laboratory and managed the ANSTO Institute of Environmental Research Inorganic, Radiochemistry and Tritium Analytical laboratories. In 2002 he was invited to join Standards Australia, and currently serves as Chair of the spectroscopy committee.

ANA 2014 Award to Dr Rob Robinson

As announced at the ANA AGM, the recipient of the ANA 2014 Award is Dr Rob Robinson in recognition of his contribution to the establishment of the Bragg Institute as a world class facility for using neutrons and X-rays for research and industry. His commitment to developing instrumentation on the OPAL neutron beams has been a major factor in acceptance of the OPAL reactor as an important science facility in Australia.

Dr Robinson will be presented with the Award at the ANA Annual Lunch on Friday 5 December in Sutherland NSW. Please advise ANA if you would like to receive the flyer for the lunch when it is distributed.

ANA Statement on Nuclear Power

The ANA Committee has prepared an updated Statement on Nuclear Power. This Statement provides background to the ANA's previously expressed support of the use of nuclear power for Australia and our nation's involvement in all stages of the nuclear fuel cycle.
