Energy generation / supply: a global challenge with social, economic and environmental aspects

4 WNU Summer Institute- G. Serviere - August 1st, 2012 - copyright EDF 2012

• Social challenge: providing secure and equal access to energy – 9 billion people foreseen by 2050

– Growth of energy demand worldwide: + 40% by 2030*

– Number of people without access to electricity: 1,5 billion in 2010*

– Supply to be secure

• Economic challenge: requiring massive investments to keep up with demand – To be installed: + 660 GW in Europe ; + 1300 GW in China**…

– Investments to be profitable ; prices to be affordable

• Environmental challenge: delivering sustainable solutions – Resource Scarcity

– Energy is the leading source of greenhouse gas emissions

Page 5: WNU Summer Institute - 一般社団法人 日本原子力産 … report independently of all line functions and have not only the right, but also the duty, to notify senior management

Global electricity landscape

• 1/3 of global energy needs met by electricity today…

• … Electricity share increasing – Urbanisation, specific usage, …

– Opportunity for substitution to low carbon energy mix

– Annual growth rate to 2030: + 2.5%

– +4800 GW to be installed worldwide by 2030

– Requires more than 50% of global energy investment

• 1/3 of electricity worldwide is produced without GHG

emissions … – 16% from hydropower, 15% from nuclear plants and 2% from

renewable sources

– 40% from coal, 20% from natural gas, 7% from oil

• … and this share must be increased

Which energy mix ? Why nuclear makes sense ?

7 WNU Summer Institute- G. Serviere - August 1st, 2012 - copyright EDF 2012

• Need for a mix or mixes that respond to the challenges

• Globally all sources will have to be mobilized

• The most relevant mix depends also on regional/national context

• Resources are very variable (gas, coal, hydro, solar, wind, …)

• Consumption structure and grid capacities,

• Political, societal and social context,

• ….

• Therefore the relevance of nuclear may vary …

• … to produce safe, clean, available, affordable electricity

• But to make sense it must be looked at with a long term

perspective

Nuclear safety has many facets

• Nuclear Safety can be looked at from different angles

• Safety in or by Design

• Safety in Operations

• Safety organization and SOH factors

• Safety culture

• Safety over time

• Safety players and respective responsabilities

• etc…

• Nuclear Safety is intrisincally linked to many other areas

• Overall performance

• Security

• etc…

Some safety principles

Nuclear Safety is primarily born by the Operators

Daily operation (operation, maintenance,…) makes or jeopardizes safety The Owner/Operator has to endorse all design choices, he will first bear the

consequences of events/accidents (together with the State)

At the same time Need for a strong and competent safety authority Need for competent designers and suppliers

Nuclear safety is based on and made by Knowledge + Methods/Tools + Culture

Page 18: WNU Summer Institute - 一般社団法人 日本原子力産 … report independently of all line functions and have not only the right, but also the duty, to notify senior management

Nuclear safety management, safety culture

Nuclear Safety is based on and made by Knowledge Methods/tools Culture Leadership

INSAG 4 definition of Safety Culture: That assembly of characteristics and attitudes in organizations and individuals

which establishes that, as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance

Questionning attitude Rigorous and prudent approach Communication

EDF Group Nuclear Safety Policy

ISSUED THE 20TH JANUARY 2012 BY CEO OF EDF

NUCLEAR SAFETY INSIDE THE GROUP

RESTS ON THE PRINCIPLE OF CLARITY OF RESPONSIBILITY AND CONTROL

• Each nuclear operating company inside the group acts under the framework of legal obligations and

regulations specific to its country and must comply with them. Each guarantees and continuously

improves its safety performances with its own methods, skills and values.

• EDF respects national differences, across the Group, whilst developing common principles to deliver

the highest level of incident prevention and protection of the public, workers, and the environment.

This policy covers all aspects of nuclear – for example, new build, architecture, design and

construction – and all aspects of the existing stations – operation, maintenance, waste management,

decommissioning and off-site support. The Group works closely with its industrial partners to deliver

this.

• Each company is responsible for, and assigns adequate delegation at, each level of management or

operation : clear organization, the required skills and decision-making capacity, access to support

and resources. The Group guarantees the allocation of resources needed to ensure nuclear safety.

• And in-house independent nuclear safety assessment function is put in place at power station

level, company level and Group level. Each report independently of all line functions and have

not only the right, but also the duty, to notify senior management of inappropriate or

inadequate line management response.

EDF Nuclear Engineering Division (DIN) is in charge of Safety in Design on behalf of the Owner/Operator

• Same principles apply for Nuclear Engineering Division

– Knowledge + methods /tools + culture

– Independant line focused on nuclear safety in Design *

• Technical aspects may have more importance than managerial ones in Design process compared to Operations, … – Licensing process – Easier (?) to regulate design technical issues than SOH in

operations, – … but Safety in Design has also to be managed, and DIN is the

“Engineering of the O/O”, and therefore is also the prime responsible for the safety in its own activities, resulting in the same overall philosophy of culture and organization

Main reasons linked to Design

Earthquake :

Earthquake magnitude higher than Design Basis

But not a real cause of damage (automatic shutdown, diesels started, …)

=> Design margins

Loss of external sources

Flooding (tsunami subsequent to seism)

Tsunami far more important than heigths anticipated in design

Loss of heat sink and cooling capabilities

Loss of all emergency electrical sources (but one in unit 6)

inadequate (wrong) evaluation of the risk of tsunami

Absence of robustness of safeguard systems vis-à-vis flooding

WNU Summer Institute- G. Serviere - August 1st, 2012 - copyright EDF 2012 41

Main reasons linked to emergency preparedness

Absence of ultimate external means, sufficient and availaible in due

time, to refeed water and electricity Availaibility of equipment and decision making processes

Difficulties to manage the confinement of reactor core in a severe

accident condition Management of pressure inside containment

Hydrogen explosions, resulting in additional damages

too limited defence in depth

A rather slow kinetics of the accident … which as a paradox

Did not allow to bring in sufficient or adequate additionnal external equipment,

in a disturbed environment,

But allowed to take measures to protect or evacuate people (despite many

problems)

… with limited sanitary consequences Thanks to provisions that were taken, but also to meteo (winds) often

favorable

Most probably no fatalities due to irradiation/contamination exposures

But >80 000 persons displaced and evacuated zones to be handled in the long

term

Main reasons linked to emergency preparedness

In conclusion incorporating a few post Fukushima considerations

• Technical considerations • Importance of site hazards characterization, and more generally DesignSite

adequation

• Importance of some real robustness beyond design events (no cliff edge effects, diversification, …, defence in depth)

• Importance of periodic re-questionning attitude including incorporation of operation/event feedback and related upgrades (periodic safety reassessments, event assessments, …)

• Governance & organizational considerations • Necessary ownership by Owner/Operator of Design and Site characteristics

O/O must be able to take such responsibilty, with full understanding of consequences,

"Architecte Ensemblier" model is a way to ensure such responsibility

• A renewed and reinforced world oversight and governance to ensure nuclear safety

• Importance of a well defined and trained emergency organization

EPR Design anticipated some of Fukushima lessons

EPR • Developped after TMI / Chernobyl / September 11,…

• Incorporating lessons and improvements

• A “hard way” and/or “hardware” approach

• not simply a “probabilistic” approach to exclude /characterize events

• not simply a “passive” approach, to avoid overconfidence and be safer

• 3 main axis for design and improvements

• Reliability and robustness

• Severe accidents

• External hazards

To sum up:

• For Utilities, as part of an energy policy, nuclear is a means to provide safe, clean, available, affordable electricity. It’s not an ideology,

• Safety is a condition that has to be met, consistently with societal expectations,

• Nuclear Safety is a complex and living concept, based on knowledge + methods and tools + culture.

• It relies on people, individually and collectively, at all levels of the organization; focused leadership is essential

• Among the methods/tools, an independant safety line is a major guarantee to keep focused on the safety priority

• Educating, recruiting, training people is a necessity that takes time and requires a systematic approach, including for newcomers

A very important part of the skills build-up

Nuclear skills, is also a "collective skill"

not just a sum of individual skills

Vocational training organization

An Academy for Operations, (1st year).

An Academy for Engineering, (1st year).

(adapted according to initial academic education)

Nuclear education and training courses for people in charge of

Operations (operators, safety engineers,…).

(both initial education and training, as well as periodic training)

Specific and specialized courses in a variety of domains,

to train /accompany personnel during their professional career.

Education and training:

a significant component of safety and performance

• A real need to continue and strengthen education and training, to face the future of nuclear energy

– Getting all the properly trained people is a real challenge, – But it has already been met successfully in the past, and will be again – A most important challenge to newcomers

• EDF is committed to contribute to this effort, and launched a number of initiatives, – Internally, – Towards the academic education system – Including human and financial support – Open to international

• a large and comprehensive in-house training organization – designed to be effective for a large number of diversified needs – Which can be opened/adapted to other Operators/Entities within various type of

agreements/contracts

• the international Master in Nuclear Energy – a significant contributor to an appropriate initial education, in line with the needs of

Operators and Industry – open to students from France and other countries – Sponsored by EDF and benefiting from the French context and facilities – Is a main component of the International Institute for Nuclear Energy
