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
    Chinas 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

9
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

18
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

19
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

20
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 Peoples
    Republic of China was approved by the National
    Peoples Congress (NPC)
  • The Radioactive Pollution Prevention Act is a
    basic law for the radioactive waste management

21
Nuclear Safety and Wastes Management
  • To meet the needs of nuclear energy development,
    independent regulatory authorities and
    implementation bodies came into being in Chinas
    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
    facilitieslicensing management and routine
    monitoring

22
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

23
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.

24
Establishment of Nuclear Fuel Cycle System
25
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

26
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

27
Cardinal Principles of Waste Management
  • Relevant radioactive waste treatment facilities
    should be designed, constructed and operated
    simultaneously with facilities or practices
    producing radioactive wastes

28
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

29
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.

30
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

31
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

32
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

33
Treatment and Disposal of HLW
  • Spent fuel storage
  • Reprocessing
  • Vitrification of HLLW
  • Deep geological disposal of HLW

34
Spent Reprocessing
  • Initiate target recovery of uranium and
    plutonium for resource conservation
  • Long target
  • Reprocessing partitioning ? transmutation
    remove trans-uranium and separate strontium and
    cesium
  • Improvement of resource utilization
  • Minimizing the radioactive toxic
  • Reducing the waste repository volume

35
Spent Reprocessing
  • Scientific research and test verification carried
    out for a 50 tU spent fuel project
  • A commercial facility put into operation after
    2020

36
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

37
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
