• Chin invest 67.7 billion $ to renewable energy in 2012 which is the largest in the world.

• Policy：

– Ensure safety and developing with high efficiency

– Three documents：

• The 12th five years plan and 2020 perspective goal of nuclear safety and radioactive pollution prevention

• Nuclear energy safety plan (2011—2020)

• Nuclear energy middle-long term development plan (2011—2020)

• Technical requirements：

– The new NPPs should adopt the most advanced technology and the most strict safety standers.

– The NPPs site must be consider the extreme disaster include large earthquake and tsunami

– Special safety features to mitigate server accident

– From 2016, the new NPPs must eliminate the large scale release of radioactive material.

• After very careful check, the China government decide to restart NPPs building from 2012.

• The projects to be restarted: – Tianwan 3#

– Fuqing 4#

– Yangjiang 4#

– Shidaowan HTGR project

• Tasks：

– Meet the need of energy consumption growing

– Meet the need to improve the China energy structure.

• Challenges：

– Scale and speed. It should depend on the country development.

– Safety. It should be satisfied to the latest requirements after Fukushima accident.

– Economy. It should be better than coal power station

– Sustainable. The whole fuel cycle system should be established

• Uranium resource is sufficient. The main task of fast reactors is to transmute MA of PWR spent fuel. In this case, capacity of fast reactor is about 70GWe or less.

• Uranium resource is shortage. The main task of fast reactors is to breed. The FR capacity may be more than 200GWe.

• Phase 1： – Reprocessing plant of PWR spent fuel (provide Pu to FR).

– MOX fuel plant

– Breeding FR (BR≈1.2)

– Reprocessing plant of FR spent fuel

• Phase 2： – Metal fuel plant

– Pyroprocessing plant

– High breeding FR with metal fuel (BR>1.2) while the nuclear grow fast, and

– Low breeding ratio (BR≈1) while nuclear energy maintain a fixed level.

• The scale of PWR is large enough which could provide initial fuel loading and refueling fuel to FR

• Uranium becomes expensive enough.

• Safety level has been validate and could be built at inland site.

• Cost is lower than coal power plant.

• Fuel irradiation

• Material irradiation

• Accumulate operation data and experience

• Develop new technologies to enhance safety and reliability

• Feedback to design to improve the economy

• Validate the technology of fuel cycle on laboratory level

• Equipment development.

• Industry demonstration

• Accumulate experience of FR power station

• Validate the reliability of sodium fast reactor

• Preliminary validate the economy of SFR power station

• Realized the industry size fuel cycle

• China devotes herself to the peaceful use of nuclear to meet the growing energy demand. Proper amount of nuclear power plants could provide clean energy with low risk.

• Fast reactor is a promising technology to ensure the sustainable development of nuclear energy, which can produce new fuel from depleted uranium and burn the long-life radioactive waste at the same time. It is expected that fast reactor will provide enough clean power to people for a long term in the future.
