The Police and Planning of Nuclear Energy
Nuclear power, with clean, safe, high efficiency and economic characteristics, is one of the world's supporting energy as well as coal and oil. Other developed countries have already greatly exceeded China on nuclear power construction. It is an inevitable trend to develop clean and environmental nuclear power in China.
Establishing national nuclear power industry. General Secretary HU has made such 3 orientations as “national”, “high-tech” and “strategy” for China’s nuclear power industry.
Since 2004, China government has changed the police of nuclear development from “moderate” to “ active”

The Police and Planning of Nuclear Energy
11 NPP in operation, total 8.6 GW installed capacity
52.3 billion kWh - 2.1% of total power generation
Accept 2 units of CANDU PHWR type, others PWR type
Planning of Nuclear Power Development
The government plans to increase nuclear generating capacity to 40 GWe by 2020 with a further 28 GWe nuclear being under construction then
Requiring an average of 2 GWe per year being added.

Open Bidding for Third-generation Designs
In September 2004 the State Council approved the two units at Sanmen, followed by six units at Yangjiang (two to start with), these to be 1000 or 1500 MWe reactors
The Sanmen and Yanjiang plants were subject to an open bidding process for third-generation designs, with contracts being awarded in mid 2006
Westinghouse bid its AP 1000 (which now has US NRC final design approval), Areva NP (Framatome ANP) bid its EPR of 1600 MWe
NPP Technologies
PWRs will be the mainstream but not sole reactor type
Nuclear fuel assemblies are fabricated and supplied indigenously
Domestic manufacturing of plant and equipment will be maximized, with self-reliance in design and project management
International cooperation is nevertheless encouraged
New Nuclear Power Reactor Technology Development
In February 2006 the State Council announced that the large advanced PWR and the small high temperature gas-cooled reactor (HTR) are two high priority projects for the next 15 years
In order to master international advanced technology on nuclear power and develop a Chinese third-generation large PWR“
CNNC has confirmed this, while pointing longer-term to fast neutron reactors
National Laws
The Atomic Energy Act is a supreme legal document in nuclear field to adjust and promote the atomic energy development in China
The Atomic Energy Act being worked out The Environment Protection Act of the People’s
Republic of China was approved by the National People’s Congress (NPC)
The Radioactive Pollution Prevention Act is a basic law for the radioactive waste management
Nuclear Safety and Wastes Management
To meet the needs of nuclear energy development, independent regulatory authorities and implementation bodies came into being in China’s radioactive waste management system in virtue of years of practices.
The State Environment Protection Agency (SEPA), independent of the nuclear industry, carries out supervision and management on nuclear safety and radiation environment of civilian nuclear facilities: licensing management and routine monitoring
Rules and Regulations by Governmental Departments
Detailed Implementation Rules have been promulgated in succession:
National Regulations on Supervision and Management of Safety of Civilian Nuclear Facilities
Provisions on Safety of Civilian Nuclear Fuel Cycle Facilities
Provisions on Safety of NPP Radioactive Waste Management
Environmental Policy on Intermediate and Low-level Radioactive Wastes Disposal
Provisions on Radioactive Waste Management
Nuclear Fuel Cycle
China has primarily established a nuclear fuel cycle system covering uranium exploration, mining and milling, conversion, isotope separation, nuclear fuel element manufacture and spent fuel reprocessing.
Establishment of Nuclear Fuel Cycle System
Uranium Resources
At present the uranium resources supply available domestically
With the prospective need to import much more uranium
CNNC is also keen to participate in exploration and mining abroad, and in 2006 bought into a small Australian uranium prospect
Cardinal Principles of Waste Management
Aiming at safety and taking disposal as core; Ensuring exposure received by workers and
the public within the dose limits set by the state, and keeping at the ALARA level when taking into account the economic and social factors;
Protecting later generations, i.e. no extra burdens and responsibilities to be added to later generations, and the protection level of individuals of later generations will not lower than the current level;
Cardinal Principles of Waste Management
Relevant radioactive waste treatment facilities should be designed, constructed and operated simultaneously with facilities or practices producing radioactive wastes
Cardinal Principles of Waste Management
Taking into full consideration the inter-relations between various phases of waste management:
reduction in output categorized collection purification and concentration, volume reduction
and solidification careful encapsulation, safe transportation in-situ interim storage concentrated disposal, controlled discharge
Cardinal Principles of Waste Management
The environmental impact assessment should be conducted prior to any waste management facility or practice.
The discharge amount should be applied for to environment protection agencies.
The amount and concentration of radioactive materials discharged to environment must lower than the discharge limits set by regulatory authorities.
Treatment of L/ILW
L/ILW arising from NPPs will be cement-solidified in 200 L steel barrel or large concrete container
Development of a series of cement formulas, methods to examine the solidification performance, and some cementation apparatuses
Near-surface Disposal of I/LLSW
Near-surface disposal of I/LLSW including cement formula piles and hydraulic fracture disposal
Following the policy of regional disposal of I/LLSW, China has set up several state regional I/LLSW disposal sites where nuclear installations are comparatively concentrated
Near-surface Disposal of I/LLSW
The northwest I/LLSW repository put into operation with planed capacity of the first phase is 5,200,000 m3
The design disposal capacity of Guangdong Beilong repository, closing to the Daya Bay and Ling Ao NPPs in Shenzhen, is 80,000 m3
Repository in Zhejiang in planning

Spent fuel storage
Reprocessing
Vitrification of HLLW
Deep geological disposal of HLW
Spent Reprocessing
Initiate target: recovery of uranium and plutonium for resource conservation
Long target: Reprocessing + partitioning → transmutation: remov
e trans-uranium and separate strontium and cesium Improvement of resource utilization Minimizing the radioactive toxic Reducing the waste repository volume
Spent Reprocessing
Scientific research and test verification carried out for a 50 tU spent fuel project
A commercial facility put into operation after 2020
Deep Geological Disposal of HLW
Plan for deep geological disposal of HLW consists of four stages: technical preparedness; geological research; on-site test and construction
Great progress on sitting for repository and underground laboratory, and the feasibility study
Northwest region of China: primarily determined as one of the most likely candidate sites
Two wells as deep as 700 m and 500 m respectively drilled for carrying out multi-disciplinary research
Decommissioning of Nuclear Facilities
Drafting National standard Safety Requirements for Decommissioning of Nuclear Facilities
Carrying out relevant development work Assessment of radioactivity inventory Decontamination Cutting technology Remote operation Smelting Radioactive waste management Health protection and safety
