Fit for
purpose safety cases – considering the role of the human Jonathan Pyke, Inspector, Nuclear Safety, Operational Facilities
Division, Office for Nuclear Regulation
· Provide an overview of what fit for
purpose is
· Highlight the importance of considering
the role of the human in achieving fit for purpose outcomes
· Explain applicable activities to consider
the role of the human, including allocation of function, task analysis and
prototyping and commissioning

The challenge
of maintaining appropriate safety case rigour in an aging nuclear power
station fleet
Michelle Hoy, Head of Design Authority,
Nuclear Generation, EDF-Energy Generation
· EDF operate 7 Advanced Gas Cooled Reactors
in the UK, which are now in the extended phase of their operating lives.
· The power station safety cases have evolved
over the years through numerous changes in plant design and operation
together with advancements in codes, standards and risk assessment
techniques. This has led to significant
increases in both safety case complexity and rigour.
·
The
goal remains unchanged; to ensure that the management of nuclear risk remains
in line with the ALARP (As Low as Reasonably Practicable) principle. However,
when faced with a fleet of aging power stations of unique UK design, it is
imperative that appropriate safety case rigour is favoured over the
‘ratcheting’ of standards in order to effectively manage the safe transition
through to end of life.

HPC Safety
Case – A people enterprise
Chris Quick, Head of Design Authority,
HPC, EDF-Energy
· Delivering a safety case on a project of
HPC magnitude is a significant undertaking that is wide ranging and involves
many people
· Modern safety case expectations including
requirements, Golden Thread & new build ALARP drive extra activities
· The volume of changes that have to be
assessed and sentenced in terms of nuclear safety significance is very high

Discussion
Groups
Topics to include:
· What does appropriate rigour look like when
producing a safety case – and how does this relate to fit for purpose safety
cases?
· How do you implement ALARP at end of life?
· How can we improve the visibility of safety
cases?
· What are the opportunities for
collaboration across the industry to develop and retain the safety case
professionals of the future?
· How do we ensure safety cases adequately
take account of OPEX?
· What needs to change in the way safety
cases are planned, produced and implemented to ensure appropriate, timely and
proportionate inclusion of HF?
