Nuclear Growth in the Coming Decades
• Most of the nuclear growth in the coming decades will happen in mature
nuclear countries that conduct R&D programs:
-
On spent fuel reprocessing and recycling
On Fast Neutron Reactors for managing Actinides (TRU) and achieving durable
nuclear power when Uranium becomes scarce and expensive
• Not all member countries of the Non Proliferation Treaty
• The safe and peaceful development of nuclear power will benefit from the
continued support from International Agencies (NEA & IAEA) and Atomic
Energy Communities (Euratom, ABACC…)
-
Information exchange on good practices and R&D issues
Safeguarding nuclear materials and facilities (IAEA, Euratom, ABACC…)
WNA, WANO, INRA, WENRA…
• Need for accompanying measures for nuclear newcomer countries to
implement the Framework & Infrastructures necessary for the safe and
efficient development of nuclear energy

Nuclear Energy International Outlook
• Drivers for nuclear growth
– Energy security
– Containing climate change
• Global prospects for nuclear growth (13% ~20% nuclear power in 2050)
2°C scenario: 390 GWe 930 GWe: + 12 GWe/y new nuclear capacity
(Joint IAE-NEA 2014 Technology Roadmap for Nuclear Energy (2050))
392 GWe ~620 GWe (+350 GWe – 150 GWe) in 2040 ( ~700 GWe in 2050)
(IAE 2014 World Energy Oulook – Central scenario)
• Contrasted national nuclear plans
– Japan: restart NRA approved NPPs 20-22% nuclear in 2030
– China, India, Korea, Russia: Dynamic nuclear growth
– Western world: nuclear Recovery? Revival ?
(but Germany, Switzerland, Italy)
• Gen III/Gen III+ reactors on the market: ABWR, ESBWR, AP1000, EPR, AES2006,
VVER1200, APR1400, APWR, ATMEA1, ACR1000, CANDU6, CAP1000...
• SMRs as potential game changers?
(NuScale, mPower, Westinghouse, SMART, Floating NPP, Holtec…)
• Towards enlarged nuclear missions for nuclear reactors?
(Variable electricity, Coupling with energy storage, District heating, Process heat, Hydrogen…)

An integrated vision of Sustainability
that is a condition for public acceptance & government support

Nuclear Security
• Nuclear power will be unable to gain the support it needs
for large-scale growth unless nuclear facilities and nuclear
stockpiles are seen to be safe and secure
• Effective security is a key enabling factor for nuclear energy,
just as safety is
• Nuclear nonproliferation cannot be reliably achieved if states or terrorists
groups might gain the means to a nuclear weapon or nuclear weapon material

Treaty on the Non-Proliferation of Nuclear Weapons
• The Non-Proliferation Treaty
-
•
A balanced "three-pillar" system
-
•
Prevent the spread of nuclear weapons
and weapons technology
Promote cooperation in the peaceful uses of
nuclear energy
Further the goal of achieving nuclear
disarmament
Entered into force in 1970
Non-proliferation
Disarmament
The right to peacefully use nuclear
technology
A central bargain
"the NPT non-nuclear-weapon states agree
never to acquire nuclear weapons and the
NPT nuclear-weapon states in exchange
agree to share the benefits of peaceful
nuclear technology and to pursue nuclear
disarmament aimed at the ultimate elimination
of their nuclear arsenals"
900 facilities in 64 NPT countries
Recognized nuclear weapon state ratifiers
Recognized nuclear weapon state acceders

sensitive fuel cycle technologies
Fuel Cycle Nations – Operate both nuclear power
plants and fuel cycle facilities
Reactor Nations – Operate only reactors, lease and
return fuel
• Exclusively Uranium as
fresh fuel
?
Q: Management of nuclear
spent fuel :
• Retrieval ?
• Local storage for an
indefinite period of time?

Management of Spent Exported Nuclear Fuel
Retrieval or local storage?
Retrieval in an International Centre for Fuel
Cycle Services
Storage on National/Regional site
for an indefinite period of time
National regulations generally prohibit
retrieving nuclear waste (incl. spent nuclear
fuel) from other countries on the national
ground leasing nuclear fuel (EU…)
•
Need to create a national or a regional
interim storage of spent nuclear fuel
•
Need to plan for an end point for the spent
nuclear fuel
•
Some national or regional regulations
prohibit leasing nuclear fuel from other
countries (EU directive…)
•
•
Countries hosting an International Centre for
Fuel Cycle Services tend to restrict leasing
offers of nuclear fuel for reasons of public
acceptance
•
Issues associated with the transport of
nuclear materials
•
Risk of creating a « mine » of TRU materials
that could progressively escape the contol of
user nations
Effectiveness of instrumentation to monitor
the site ? Calls for long term monitoring measures
Need for an inter-governmental framework for securing the circulation & use
of nuclear materials worldwide through appropriate safeguarding measures

Cooperative Approaches
to the Back-end of the Nuclear Fuel Cycle
Other Issues and Impediments
• Variety of national legislative frameworks
-
International agreements / national laws for managing nuclear materials
Transfer of responsibilities
Transboundary shipments
• Public perception / acceptance
• Sentiment of lack of urgency to implement end points for spent nuclear fuel
(SNF) or high level waste (HLW)
• Newcomer countries tend to favor leasing nuclear fuels or regional interim
storage facilities
Q: Possibility of transferring to another State, the responsibility of spent nuclear fuel
management?
Q: Would the exporting country retain an obligation to assure that the SNF is
managed responsibly regardless of the terms of any specific arrangement?
Q: Does the exporting country need to be prepared to accept the return of SNF in case of
changes in national laws of the receiving country?
• New forms of contracts: Build Own Operate Projects
(Akkuyu project in Turkey…)
