Title: New Reactors


1
New Reactors
  • Bill Borchardt
  • Director, Office of New Reactors

2
Nuclear Energy Worldwide
  • There are currently 435 commercial nuclear power
    reactors operating in 30 countries
  • Nuclear power provides over 16 of the world's
    electricity and 34 in the European Union.
  • 30 more power reactors are under construction,
    while over 60 are firmly planned

3
Conditions of the mid-1980s did not favor nuclear
construction
  • Energy efficiency improvements
  • Economic restructuring
  • Significant drop in electricity demand
  • Excess generating capacity
  • Oil (traded fossil energy) price collapse
  • Electricity market liberalization privatization
  • Regulatory interventions after TMI
  • High Interest rates
  • Chernobyl

4
Conditions of today are distinctly different from
the mid-1980s
  • Strong energy demand growth
  • Fossil fuels no longer cheap
  • Energy supply security concerns
  • Attractive life cycle costs of nuclear power
  • Pollution control and climate change
  • Excellent operating experience
  • Renewables and efficiency improvements Low

Energy Policy Act of 2005
  • Authorizes federal risk insurance for the next 6
    nuclear plants for delays associated with NRC
    reviews (500 M for first 2 plants, 250 M for
    next 4 plants)
  • Nuclear energy production tax credits for the
    first 6,000 megawatts of electricity from new
    advanced reactors
  • Authorizes 3 billion in nuclear research and
    development to support NGNP and NP2010

7
National Programs
  • NP2010(Nuclear Power 2010) A joint
    government/industry cost-shared effort to
    demonstrate key regulatory processes associated
    with siting and building new nuclear power plants
  • NGNP (Next Generation Nuclear Plant) A
    demonstration reactor at Idaho National
    Laboratory that will serve as a test for advanced
    reactor technologies and for cogeneration of
    hydrogen by nuclear energy.
  • GNEP (Global Nuclear Energy Partnership) A
    program to develop new proliferation-resistant
    recycling technologies in order to produce more
    energy, reduce waste, and minimize proliferation
    concerns.

8
NRC Mission
  • NRC Mission Statement
  • To regulate the nation's civilian use of
    byproduct, source, and special nuclear materials
    to ensure adequate protection of public health
    and safety, to promote the common defense and
    security, and to protect the environment.
  • Office of New Reactors
  • The Office of New Reactors serves the public
    interest by enabling the safe, secure, and
    environmentally responsible use of nuclear power
    in meeting the nation's future energy needs

9
Resurgence of Nuclear Power
  • 29 new plants at 20 sites proposed by the
    industry
  • Five different plant designs proposed
  • AP1000
  • Economic Simplified Boiling Water Reactor
  • Evolutionary Power Reactor
  • Advanced Boiling Water Reactor
  • Advanced Pressurized Water Reactor

Potential New Reactor Applicants
12
Part 52 Licensing Process
  • Provide a more predictable licensing process
  • Resolve safety and environmental issues before
    authorizing construction
  • Provide for timely meaningful public
    participation
  • Encourage standardization of nuclear plant
    designs
  • Reduce financial risk to nuclear plant licensees

13
Part 52 Licensing Process
Early Site Permit Or Equivalent Siting
Information
Pre-Construction
Post-Construction
Combined License Review, Hearing, and Decision
Verification Of Regulations with ITAAC
Reactor Operation Decision
Optional Pre-Application Review
Standard Design Certification Or Equivalent
Design information
A combined license application can reference an
early site permit, a standard design
certification, both, or neither. If an early
site permit and/or a standard design
certification is not referenced, the applicant
must provide an equivalent level of information
in the combined license application.
14
Early Site Permits (ESPs)10 CFR Part 52, Subpart
A
  • An ESP is a license (partial construction
    permit)
  • Review scope
  • Site safety
  • Environmental
  • Emergency preparedness
  • Mandatory hearing
  • Permit good for 10-20 years
  • Allows applicant to bank a site
  • Two ESPs issued (Clinton and Grand Gulf), 2 under
    review (North Anna and Vogtle)

15
Standard Design Certifications
  • Allows an applicant to obtain pre-approval of a
    standard nuclear plant design through rulemaking
  • Reduces licensing uncertainty by resolving design
    issues early in the licensing process
  • Facilitates standardization
  • Higher degree of regulatory finality
  • Certification good for 15 years
  • 4 designs approved (C-E System 80 GE Advanced
    Boiling Water Reactor (ABWR) Westinghouse AP600
    Westinghouse AP1000),
  • 1 design under review (General Electric ESBWR),
  • 2 designs in pre-application activities (Areva
    EPR and the Mitsubishi US APWR).

16
Combined Licenses10 CFR Part 52, Subpart C
  • Combined License (COL) a combined construction
    permit and operating license with conditions
  • A COL is the fundamental licensing process in
    Part 52 for reducing the financial risks for
    electric companies building nuclear power plants
  • COL can reference ESP, DCR, both, or neither
  • Must meet technical standards in Parts 50, 100,
    etc.
  • 40 year duration

17
New Construction
  • Nuclear plants will be built more rapidly than
    their predecessors
  • Detailed engineering will be essentially complete
    by start of construction
  • Modular construction techniques will be used
  • Fabrication of components may begin before COL
    issuance
  • Components and modules will be fabricated in
    other countries

18
Security for New Reactors
  • Commission Policy Statement modified to encourage
    applicants to consider security early in the
    design
  • Staff to perform aircraft impact assessments on
    new designs
  • Part 52 to be revised to require applicants to
    perform aircraft impact assessments
  • Sharing insights with other countries

19
Digital Instrumentation Controls
  • Key Technical Issues
  • Cyber security
  • diversity and defense-in-depth
  • highly integrated control rooms - human factors
