AP1000 Working Group (AP1000WG)

The MDEP AP1000 Working Group (AP1000WG) was approved by the MDEP Policy Group in March 2008. The group is focused on safety design reviews of Westinghouse Electric Company's AP1000 design.

The national regulatory authorities participating in the AP1000WG include:

  • Canada (non-active member)
  • China
  • India
  • United Kingdom (non-active member)
  • United States

Technical expert subgroups have met to discuss the areas of control rod drive mechanisms, civil engineering, and squib valve design areas. A key concept of this co-operation is to make each regulator stronger in its reviews while at the same time recognising the sovereign rights and responsibilities of national in licensing reactors in their countries (see the AP1000WG programme plan for more details of the group's work). The working group also discusses issues related to the Fukushima accident lessons learned.

Key stakeholders with whom the AP1000WG interacts routinely include Westinghouse and utilities pursuing licensing and construction of the AP1000.

The AP1000WG reports its status to the MDEP Steering Technical Committee (STC) at the latter's thrice annually meetings.
