| 4

Affordable nuclear for power generation

Reduced investment per unit

Reduced Capital cost before generation of first MWh

Multi-unit financing scheme: first units financing the next units

Modular reactor, for simplified construction

Limited number of modules, manufactured in factories

Reduction of risks related to construction on site

Reduction of construction duration on site

Low power enabling simplified design with high level of safety

Simplified and compact architecture, limiting the accident initiators and scenarios

Low level of residual heat, simplified and passive safety systems

Versatility and flexibility

Flexible operation for power generation

Single to multi-SMRs facilities

SMR INTERESTS & EXPECTED BENEFITS

| 5

EDF INTEREST IN SMR

A proper response to high expectation

A relevant and affordable solution for new nuclear uses

New comers in nuclear, carbon free alternative to existing

fossil

Remote sites, isolated network, heat, steam and

desalination

Compatible and complementary with existing large

nuclear

Mid merit operation, complementary to large base nuclear

and intermittent renewable

As a world leader in nuclear technology and operation,

EDF is engaged to develop a valuable and competitive

SMR solution

SPECIFIC BREAKTHROUGHS TO CONSIDER

Standard design and international

licensing for worldwide deployment

Adapted regulatory requirements

In factory certification

Passive systems qualification

Mutualisation of systems and control room

Economic levers vs Scale effect

Modular design and manufacturing

(construction cost decrease, shortened

construction duration)

Series effect (In series production of

component, standardisation...)

Simplification of design (architecture,

components, regular civil structure, easy and

quick to build)

DISRUPTIVE SOLUTIONS RELYING ON EDF LARGE

EXPERIENCE

PWR Technology

The most mature, spread and near term technology

Relying on existing capacities (supply chain, fuel cycle industries)

NSSS integrated design Compact primary components located inside the

pressure vessel

Safety features

GEN III+, post FKS requirements

Resistance to hazards

Passive systems with large grace period

Severe accident management

Flexible and versatile

Flexible operation for power generation

Single to multi-SMRs facilities
