• Founded in 2001 on the basis of the

Uranium Institute, itself founded in 1975.

• The World Nuclear Association is the

international organization that promotes

nuclear energy and supports the many

companies that comprise the global

nuclear industry.

• World Nuclear Association membership

encompasses all aspects of nuclear

energy.

• The World Nuclear Association

Information Library is the world's "base-

load" generator of comprehensive,

accurate information on nuclear energy.

12 Working Groups:

• Fuel Cycle

• CORDEL

• Economics

• Supply chain

• Transport

• Law, etc.

Strategic outreach:

• Decision-makers

• Industry partners

• Media

• Business

associations

Past: • Investment by state-owned

utilities in regulated markets

• Clear national strategic role for nuclear energy

• Custom-made reactors: almost every reactor was different

Present - Future: • Investment by privately-owned

utilities in highly competitive markets

• Competition with multiple subsidised low-carbon generation sources in de-regulated markets

• Smaller number of vendors with “standard” reactor designs Further standardization required

to facilitate new build

5

• Current nuclear regulatory regimes

‒ Lack of international consistency and harmonization

‒ Tailored to each national regulatory framework ‒ When we cross the border, the different national

safety requirements and standards lead to different version and variant of a design becomes a First Of A Kind (FOAK)

Harmonization of regulatory requirements

Absolutely necessary for standardization !

6

Applicable and internationally recognized set of Safety requirements

‒ IAEA standards underpin safety in all countries

o Higher level in standards hierarchy, not enforceable

o Supplemented by enforceable national regulations

Need harmonized set of more detailed requirements

Need also an effort on the Industry side:

‒ Codes and Standards that are recognised as equivalent by industry (necessary for acceptance being considered by regulatory bodies).

‒ A convergence effort is required to identify differences and recognised equivalences between major codes.

7

CORDEL = Cooperation in Reactor Design, Evaluation & Licensing

Mission: Promote the standardization of nuclear reactor designs

• Every reactor vendor offers one or more standard. These ‘standardized’ designs

would be adapted to comply with the national safety standards in each country

where they are built.

• If the regulatory requirements in all countries were harmonized, the design could

go through the licensing process without adaptions or changes (other than those

dictated by site specific circumstances) and would therefore be internationally

standardized design.

• A standardized design approval process and worldwide nuclear power plant

designs would boost investment attractiveness and predictability of nuclear new

build worldwide, both in established nuclear countries and in emerging nuclear

countries. In addition, safety would be improved though more efficient sharing of

operating experience, enabling more cost effective licensing and safety analysis

and providing more effective nuclear power plant monitoring.

8

Main Objectives are to promote: – International standardization of reactor designs – International harmonization of regulatory requirements – International design approval/certification

Six Task Forces – Design Change Management [WANO, IAEA]

– Codes and Standards [MDEP, SDOs] – Digital I&C [MDEP, IAEA, IEC] – Nuclear Safety Standards [IAEA, ENISS, EUR, WANO] – Small Modular Reactors [IAEA, OECD/NEA] – Licensing & Permitting [MDEP, IAEA, OECD/NEA]

Membership – Almost all major vendors and many utilities interested in

new build, service companies, etc.

CORDEL achievements

Design Change Management [WANO, IAEA]

• Report on Design Knowledge and Design Change Management in

the Operation of Nuclear Fleets issued March 2015.

• Implementation of the Design Authority Within a Nuclear Operating

Organization issued in March 2017

• Joint IAEA, WNA and WANO Technical Meeting on Roles,

Responsibilities and Interfaces between Design Authority,

Responsible Designers and Technical Support Organizations in Dec

2017

Codes and Standards [MDEP, SDOs] • The aim of the group is to promote the convergence of requirement

defined in International nuclear mechanical design codes

• Work focuses on key technical issues which would greatly benefit from harmonization.

• Certification of NDE Personnel – Oct 2014

• Qualification of Welders and Welding Procedures – March 2016

• Non-linear Design analysis rules- Code comparison – Feb 2017

• The group is currently working on:

• A non-linear Finite Element Analysis benchmark

• Non-linear Design analysis rules best practice proposal

• A comparison of the current requirements for fatigue analysis in nuclear mechanical design codes

• Reports are endorsed by the industry, reviewed by the Standards development organisations and used to support discussions with regulators.

15

Digital I&C [MDEP, NEA/CNRA, IAEA, IEC]

• The group aims to promote the understanding of inconsistencies

in the licensing requirement of DIC systems and components,

and promote the international convergence of these

requirements

• The group has identified a number of key issues that needs to

be tackled

NPP Safety Classification for I&C Systems – Current

status & difficulties – Sept 2015

NPP Safety Classification for I&C Systems –

Comparison of Definitions of Key Concepts - Sept 2017

Defense in depth & diversity – Challenges Related to

I&C Architecture- April 2018

Defense in depth & diversity – country specific

approaches – in development

Requirements for Modernization of I&C architecture – in

development

• Close cooperation with NEA/CNRA-WGDIC

• Interact on a regular basis with IAEA and members of the TF

participate to the development of IAEA TECDOCs.

16

Nuclear Safety Standards [IAEA, ENISS, EUR, WANO]

• This group provides industry views and comments with ENISS

(European Nuclear Installations Safety Standards) on new or revised

safety standards at the request of the IAEA.

• Following excerpt taken from the 6th Three Year Report (2011 -2013):

Observers such as World Nuclear Association or ENISS are very active

NUSSC contributors, ………. By providing industry views, both

organizations help NUSSC to take a better informed decisions. An

example of valuable World Nuclear Association and ENISS input was on

the review of DS367 (Safety Classification of Structures, Systems and

Components) and the resolution of issues raised during the review,

…….. Industry input in the review of Safety Standards is therefore valued

…….

Small Modular Reactors [IAEA, NEA/OECD]

• Report on Facilitating International Licensing of Small Modular Reactors

published August 2015.

• Currently working on:

• In-Factory Inspection and Release Certification

• Roadmap for Deploying SMR Technology in an Emerging Country

• Cooperation with IAEA SMR regulators’ Forum

17

Licensing & Permitting [MDEP, IAEA, OECD/NEA]

• The New Build Licensing Conference was held 20th – 21st April 2015 in Prague.

• The participants noted that while barriers exist in both the technical and political

arenas, the consensus is that continued dialogue between the regulatory and

licensee communities is essential. This can best be carried out through

programmes such as MDEP and CORDEL and communications of the sort that

has already been established between these two groups.

The CORDEL position paper “CORDEL

View of the Multinational Design

Evaluation Programme” was well

received. MDEP has sent a formal

response with agreement of CORDEL

propositions.

MDEP Policy Group Meeting (June

2015) has decided on the future of the

program, and the decisions have been

presented during MDEP/CORDEL

September meeting.

18

CORDEL published a position paper “CORDEL View of the Multinational Design

Evaluation Programme” in March 2015 which provides an overall CORDEL

statement on the future of MDEP, recommendations on various aspects of the

MDEP work including collaboration with CORDEL and a number of proposals on

potential issues.

CORDEL Statement:

‘The CORDEL Working Group believes that any decision to continue, change or close MDEP is entirely up to the MDEP membership. However, CORDEL regards it is as essential that regulators, through whatever means appropriate, maintain a discourse on regulatory reviews of new reactor designs.’

2014: MDEP requested CORDEL to provide an official industry position about MDEP

February 2015: CORDEL position paper on MDEP, providing

– Overall statement on the future of MDEP – Recommendations and proposals on MDEP work

including collaboration with CORDEL

August 2015: MDEP positive response – Agreeing that interactions with industry are beneficial

and should continue – To CORDEL seven specific proposals

June 2016: MDEP second letter stressing on: – Coordination – Harmonization of codes and standards – Design standardization throughout the plant life cycle

and cooperation among regulators post-licensing
