Moving forward
after Fukushima
International Symposium on Nuclear Safety
Mar.14~15,2013
Bratislava, Slovakia

JAIF
Current status of Fukushima
--- on site --- cooling
cooling sys. of the damaged core and SFP was established
and controlled stably
- confinement
release of radioactive material into the environment have
been dramatically suppressed
- effluent water management
large volume of contaminated effluent water have been
treated and recycled as cooling water for damaged core
- decommissioning
mid. & long term road map towards the decommissioning
was decided and deployed
2
Current status of Fukushima
--- off site (1) --
Contamination
highly contaminated in NW
direction over 30 km
Entry restriction
zoning by level of contamination
(Apr. 2011~)
- Restricted Area
- Deliberate Evacuation Area
- Evacuation Prepared Area in Case of
Emergency
latest zoning (Mar.2012~)
- evacuation orders are ready
to be lifted
- the residents are not permitted to live
- the residents have difficulties in returning
for a long time
3
Current status of Fukushima
--- off site (2) --- evacuation
more than 150,000 people have suffered as evacuee apart
from their hometown
- compensation
TEPCO has implemented compensation based on the Nuclear
Damage Liability Facilitation Fund Law
- decontamination
decontamination work has been deployed based on the model
projects but not progressed smoothly
- waste management
storage/disposal of radioactive waste generated in the
process of decontamination has been one of the biggest issue

Roadmap for Decommissioning
Starting Pt. Dec.2011
Removal of Spent Fuel from the SF Pool
- unit 4 : start within 2 yrs.
- unit 1, 2, 3 : start within 3 yrs.
& complete within 10 yrs
Removal of Fuel Debris
- start fuel debris removal within 10 yrs.
- complete after 20~25 yrs.
Dismantling of plants
- complete after 30~40 yrs.

Roadmap for Decontamination

Current status of
Nuclear Power Plant in Japan
: In operation
(2 unit, 2.36GWe)
: Outage for the periodic
inspection
(35 units, 30.61GWe)
: Shutdown due to tsunami
anand the government
request
(13 units, 13.18 GWe)
TOTAL : 50 units, 46.15GWe
7
Effects by suspension
of NPP operation in Japan
Restart of operation of aged fossil plants
Increase import of oil and gas
- LNG import : 70Mt(2010)/87Mt(2012)
- additional cost to purchase : ~30B Euro (~40B$)
Economic pressure on utility companies
Electricity rate change
- Burden on industries ~ 15% increase
- Burden on household expenditure ~10% increase
Increase CO2 emission 200Mt
Risk on stable supply of electricity
8
Basic Energy Policy of Japan
before 3.11
simultaneous achievement of 3E
3E : Energy security
Environmental conservation
Economic growth
after 3.11
S+3E
S : Safety
9
Role of Nuclear Power
in Japan --- before 3.11 --54 NPPs (30 BWR, 24 PWR) 49GWe, ~300Twh
Power Generation by Nuclear (~30%)
Gas (~30%)
Coal (~20%)
Oil (~10%)
Renewable incl. Hydro (~10%)
Reduction of CO2 emission by Nuclear
~200Mt CO2 (~15% of Japan)
10
Deliberation on
Energy policy after 3.11 (1)
under the Former Administration (DPJ)
“Innovative Strategy on Energy & Environment” (14/9/12)
“Future Policies for Energy and Environment” (19/9/12)
Realization of a Society
not Dependent on Nuclear Power
Gov. of Japan mobilize all possible policy resources
to such a level as to even enable zero operation of
nuclear power plants in the 2030’s
principles
1. 40years life
2. restart after NRA review
3. no new construction
11
Deliberation on
Energy policy after 3.11 (2)
under the New Administration (LDP)
more positive on Nuclear than DPJ
LDP keeps cautious position until next Upper
House election (Jul.2013)
expect New Energy Policy will be more
practical considering national security
deliberation will start soon
“New Basic Energy Plan” will be finalized by
the end of 2013
12
New Government Policy
Policy Speech by Prime Minister Abe
(to the 183th Session of the Diet) Feb.28,2013
- will foster a culture of safety
- will restart nuclear power plans where safety has
been confirmed
- will promote the introduction of energy conservation
and renewable energies to the greatest possible
extent to reduce our degree of dependency on
nuclear power as much as possible
- will begin a fundamental reform of the electric
system
13
Role of Nuclear Power
World energy demand increase would be
inevitable.
For sustainable future of the planet, we
have to challenge to realize low carbon
society.
Nuclear power have played an important
role for energy supply assurance and
reduction of GHG emission.
There is no silver bullet to realize low
carbon society, but there would be no
solution without nuclear power.
14
Projections in the Growth
of World Nuclear Power
“Nuclear growth slowing not stalling”
In 2010
- in operation : 435 units (370 Gwe)
- generated power : 2700 Twh (13%)
- under construction : 65 units (65 Gwe)
~2/3 in Asia
In 2030 (low/high)
- new construction : 90/350 units
- in operation : 500/750 Gwe
Major countries to contribute for growth
- China, India, Russia, Korea, middle East, east Europe

Responsible Development
of Nuclear Power
Ensuring the 3S
(Safeguards, Safety, Security)
Preparing the solutions for radioactive waste
Human Resources Development (HRD)
Investment on R&D
Support of Newcomer countries
16
Enhancement of Safety
Deployment of SA Countermeasures
Reinforcement of Emergency Preparedness
Preparation of International Safety Standard
Infiltration of Safety Culture
Peer Review by international community
17
Enhancement of Safety
New Nuclear Safety Construct
“The new construct will expand on the
evolving safety frameworks, reaching
beyond adequate protection of public
health and safety to prevent sociopolitical and economic consequences
from a severe nuclear accident.”
proposed by ASME task force (June 2012)
18
Role and Responsibility
of Japan after Fukushima
Share the lessons learned of Fukushima
accident with international community
and enhance nuclear safety
Restore Fukushima site and
surrounding environment safely
Maintain nuclear technology and
contribute international community
Strengthen the international regime of
nonproliferation and nuclear security
19
Challenges for
moving forward in Japan
Restoration of Fukushima
- Decontamination of the environment
- Decommissioning of the damaged plants
Enhancement of Safety
Progress in SF management & HLW disposal
Improving the literacy on Radiation exposure
Rebuilding Public Confidence
20
Japan’s strength
Construction experience of 57 NPP in Japan
- 50 years continuous construction of NPP
without interruption
Technology accumulation based on R&D
Operating experience ~1500 Rx・yrs
Supply chain of high quality component
Well trained high level of workforce
Construction project management capability
- “on time, on budget”
21
Support of
newcomer countries
Japan started nuclear program in 1955
UK and USA fully supported Japan’s program
1st generation LWRs started operation 1970
establish indigenous technology by mid. 80’s
Japan will continue to support newcomer
countries even after Fukushima accident
share the lessons learned of Fukushima
accident and enhance safety
human resources development is the key pillar
22
Conclusion
World energy demand increase is inevitable
Nuclear power have played an important role for energy
supply assurance and reduction of GHG emission
To realize sustainable future of our planet, we have to
establish low carbon society
There is no silver bullet for reduction of GHG emission,
but no solution without nuclear power
We have to overcome Fukushima accident by enhancing
safety and rebuilding public confidence
To develop nuclear program steadily, we have to share
the vision and international cooperation is crucial
Japan will continue to support newcomer countries
23
Never, ever again anywhere in the world
Share the long term vision for Nuclear Energy
