1 Background

National requirement Energy supply-amount and security

2500GWe in 2050 total 16% for nuclear?

Greenhouse gas emission Roles of NPP Roles of HTR

Current NPPs Impact from Fukushima accident

3

Roles of NPP

For the national energy supply security

For the structure improvement of energy supply

For the promotion of industry technology progress

4

Roles of HTR

Supplement for the LWR For the process heat application For the technology innovation

5

Nuclear power plants in China

Currently, 15 NPP units are under operation, 26 units are under construction,

Plus 3 units ready for construction More units are under planning

But central government are reevaluating the situation, after Fukushima accident

Government NPP plan Version of 2006

To 2020, installed NPP capacity will reach 40GWe

To 2020, capacity for NPP under construction will maintain 18GWe

Current government consideration after Fukushima accident More cautious than before, affected by

international trend Not determined yet

10

Government decision after Fukushima accident

1) Immediate safety evaluation for all nuclearfacilities

2) Enhance the safety regulation foroperating NPPs

3) Thorough assessment of all NPP underconstruction, according to the advancedguidelines

4) Freeze new NPP projects, until newnuclear safety planning is approved by thecentral government

11

Progress after Fukushima accident

Safety assessment on NPP wasfinished Some new measures are adopted

New safety planning are open to public Public feedback are completed in this

June Practically eliminate the need for off-site

emergency response New nuclear development plan is

under discussion12
