power programme• Legal framework for safety

• Regulatory approaches• The role, functions and working processes of the

regulatory body• Involvement of the public and other stakeholders

• International cooperation networks

RCF meetings

• Identifieswhat legal and governmental competences are needed in

the MS• Organizes and Facilitates

Meetings and dialogue between Donator and Recipient Member States

• Provides RegNett, a Network to Exchange Knowledge

and Experience among Regulators

Related Requirements:

• Governmental, Legal and Regulatory Framework for

Safety; GSR part 1

• Management Systems for Facilities and Activities; GS-
