MDEP Annual Report [April 2016 – April 2017]

Multinational Design Evaluation Programme (MDEP)

MDEP was established in 2006 as a multinational initiative to develop innovative approaches to leverage the resources and knowledge of the national regulatory authorities that are currently or will be tasked with the review of new nuclear power reactor designs. The nuclear regulatory authorities of 16 countries participate in MDEP, which includes 6 design-specific working groups and 2 issue-specific working groups. The Nuclear Energy Agency facilitates MDEP activities by providing technical secretariat services for the programme. The MDEP Policy Group (PG) and the Steering Technical Committee (STC) oversee the programme.

Members and participants

Current MDEP members include national regulators from:

The International Atomic Energy Agency (IAEA) also participates in key aspects of MDEP's activities. For more details, please refer to the terms of reference.

Goals and activities

MDEP's main objectives can be defined as follows:

To carry out the work, two main lines of activity have been implemented:

A key concept throughout the work of the MDEP is that national regulators retain sovereign authority for all licensing and regulatory decisions.

For more information on the MDEP's accomplishments to date and future work, please see this year's annual report: MDEP 2016 Annual Report.

Communications

MDEP engages with key stakeholders involved in ensuring the safety of new reactor designs, manufacturing, construction and operation. At this time, these stakeholders include other national regulatory authorities and international organisations involved in ensuring nuclear safety including the IAEA, Western European Nuclear Regulators' Association (WENRA), NEA Committees on Nuclear Regulatory Activities (CNRA) and Safety of Nuclear Installations (CSNI), the various reactor vendors, nuclear component manufacturers, mechanical and electrical standards development organisations, reactor operators and licensees and key industry representatives such as World Nuclear Association (WNA).

To this end, the MDEP has organised four conferences (in 2009, 2011, 2014 and 2017, to communicate its work with various stakeholders. The MDEP also issues press releases that cover the programme's major events and milestones. However, individual regulators retain sole responsibility for communication on specific new reactor issues.

Update on MDEP chair and new members

As of 1 January 2015, Mr Petteri Tiippana, Director-General of the Finnish Radiation and Nuclear Safety Authority (STUK), succeeded Dr Allison Macfarlane as chair of the MDEP Policy Group. On 20 November 2017, Argentina (ARN – Nuclear Regulatory Authority) was admitted as the 16th member of MDEP.

Working groups

In accordance with the terms of reference, the MDEP carries out its work through design-specific and issue-specific working groups as follows:

  1. Design-specific activities (see Design-specific terms of reference)

    Working groups for each new reactor design will share information and co-operate on specific reactor design evaluations, construction, commissioning, and early phase operation. Participants in these working groups should be MDEP member regulatory authorities (or their technical support organisations) who are interested in a specific reactor design and are willing and capable of contributing positively to the group's activities. Design-specific working groups will be formed when three or more countries express an interest in working together.

    • EPR working group was established to conduct the activities previously carried out by the US, Finland and France to share information on the EPR safety review. Current members are regulators from China, Finland, France, India, Sweden and the United Kingdom.
    • AP1000 working group was established to share information on the AP1000 safety review. Current members are regulators from China, Canada, India, the United Kingdom and the United States.
    • APR1400 Working Group was established in May 2012 to focus on the safety review of the KHNP's APR1400 design. Its members include regulators from Korea, the United Arab Emirates and the United States.
    • VVER Working Group was established to share information on the VVER safety review. Current members are regulators from China, Finland, Hungary, India, Russia and Turkey.
    • ABWR Working Group was established in May 2012 to focus on the safety review of ABWR reactor design. Current members of the working group are regulators from Japan, Sweden, the United Kingdom and the United States.
    • HPR1000 Working Group was established in September 2017. Current members are regulators from Argentina, China, South Africa and the United Kingdom.
  2. Issue-specific activities (see Issue-specific terms of reference)

    Working groups have been established for selected technical and regulatory process areas within the MDEP's Programme of work. These currently include
