Both regulators and the nuclear industry recognise the need for licensees to develop a strong, positive safety culture to support successful and sustainable nuclear safety performance. In recognition of this, the CSNI Working Group on Human and Organisational Factors (WGHOF), together with the CNRA Working Group on Inspection Practices (WGIP) and the IAEA, organised a workshop in Chester, United Kingdom, in May 2007 to provide a forum for gathering and sharing international experience, including good practices and learning points. This was followed by a follow-up workshop, also held in Chester, United Kingdom on 26-28 September 2011.

This report sets out the findings of the “Chester 2” workshop, organised by the UK Office for Nuclear Regulation (ONR) on behalf of the CSNI/WGHOF and the IAEA. The workshop was attended by over 40 representatives of nuclear regulatory bodies and licensees from 15 countries plus IAEA and NEA. The workshop featured keynote papers on learning from major events, and from the inquiry into the Nimrod aircrash. There were also presentations by regulatory bodies on developments in their approaches to oversight of leadership and management for safety/safety culture (LMfS/SC) since the previous workshop, and by industry representatives on perceptions of regulatory approaches.
