Internal Oversight Working Group (IOWG)

Formerly the Internal Regulation Working Group - IRWG

About Us

Organisations get to learn from others’ experience and share best practice in such a way as to provide benefit throughout the sector. Members can share intelligence on emerging assurance and regulatory issues such that work can be started on these at as early an opportunity as possible. This assists in limiting the collective risk associated with these issues.

There is also the opportunity to share or develop new or revised approaches that may improve effectiveness and efficiency for all, and the forum provides a method of getting advice from others who may have already addressed a similar issue.

More specifically, the group has worked closely with Office for Nuclear Regulation (ONR) in the development of their Technical Assessment Guide (TAG) on internal challenge and safety advice (T/AST/080), resulting in a product that both ONR and the industry is happy with
