  • Technico-economic comparison of long-term nuclear
    fuel cycle management scenarios application to
    the French context
  • N. Jestin-Fleury
  • International seminar on "the re-emergence of
    nuclear energy
  • an option for climate change and emerging
    countries?",
  • Mexico City, 19-20 April 2006

2
Radioactive waste management the French context
  • Low-level and short-lived radioactive waste are
    industrially packaged and sent to a centralized
    surface disposal
  • (Soulaines, Aube)
  • Intermediate and high-level and long-lived
    radwaste are stored on their production sites,
    waiting for a long-term and sustainable
    management solution
  • The French RD law called "Bataille law"
    (December 30th, 1991) defined three ways of
    research for 15 years
  • advanced partitioning and transmutation (way 1)
  • deep geological disposal (way 2)
  • packaging and long-term storage (way 3)
  • Ways 1 and 3 have been coordinated by CEA
  • Way 2 has been coordinated by ANDRA

Radioactive waste management the French context
Main conclusions of the National Evaluation
Commission Way 1 French researches on advanced
reprocessing have been innovative and lead to
sufficient results to foresee an industrial
application. However, there will not be
arguments in 2006 to decide anything on minor
actinides transmutation. A long RD process is
needed yet, with international collaboration, as
it is engaged in the Generation IV nuclear
forum. Way 2 information obtained by
experimentations in the underground laboratory
could give to decisions makers, if they want, the
possibility to choose the deep geological
disposal for the ultimate radioactive waste
management. Way 3 researches on packaging
have lead to maturity and opened concrete
perspectives. However, despite its technical
feasibility, the durability of a long-term
storage has not been demonstrated up to 100
years. Long-term storage is not considered as a
sustainable way for ultimate radioactive waste
management.
5
The goals of the long-term scenarios study
Provide a technico-economic evaluation of
prospective and contrasted nuclear fuel cycle
scenarios Put in evidence the cost of
radioactive waste management and its impact on
the kwh production cost The main interest is to
compare the scenarios and to put in evidence some
significant trends These scenarios must reflect
radioactive waste management options included in
the 1991 law The scenarios are not forecasts but
only a particular vision of the nuclear fuel
cycle in the future All scenarios suppose the
sustainable development of nuclear energy
6
The main technical assumptions common to all the
scenarios
Time-horizon 2000-2150 French context
constant annual energy production 400 TWh
constant nuclear power capacity installed 60

scenarios

8
The main technical assumptions common to all the
scenarios
Waste are sent to geological disposal
after 60 years of storage for HL-LL waste and UOX
spent fuels after 90 years of storage for
MOX spent fuels immediately for ILLL
waste The geological disposal is available from
2025 it can receive all radioactive waste
produced by the nuclear park untill the 2150 time
horizon
9
The main technical assumptions common to all the
scenarios
  • Plants are supposed to operate full time
  • 100 production capacity use rate
  • A progress factor due to the return of experience
    is introduced
  • extension of the plants lifetime from 30 to 50
    years

Radioactive waste management the French context

1992, cumulated expenses 810 M on way 1 1

27
In the "Bataille law" framework, a specific
mission for the CEA
  • As IHL-LL radwaste management requires long-term
    investments, economic aspects had to be studied
    as well as scientifical and technical aspects.
  • The CEA was mandated by the French State for
    studying technico-economic waste management
    options
  • "The CEA will have to be able to propose waste
    management options which allow to enlighten
    Parliament and Government decisions at the 2006
    term (...). These options will be completed by
    the necessary technical information and
    approximative economic date to enlighten the
    decision-making process in 2006"
  • (extract from the 2001-2004 CEA-French State
    Pluriannual contract)

28
The main technical assumptions common to all the
scenarios
Control of plutonium and minor actinides (Am and
Cm) for minimizing radwaste toxicity Spent fuel
reprocessing Fuel burn-up rising UOX-MOX parity
at 60 GWj/t
29
The main technical assumptions common to all the
scenarios
Current facilities are operated as much
profitable as possible Uranium enrichment process
by gaseous technology is replaced by the
ultracentrifugation technology from 2015 No
maintenance investment is supposed (for current
plants as well as for the future plants) Material
flows and inventories determine the plants
production capacity
30
The main economic assumptions common to all the
scenarios
  • Every step of the nuclear fuel cycle is
    characterised by a unit cost
  • (a "service cost")
  • Unit costs data come from the most recent CEA
    studies, national and international (OECD/NEA,
    IAEA) public reports, communications in working
    groups, or industrial experiences
  • Costs are expressed in a single monetary unit (
    2003) and normalised to the electricity
    production (/MWh)
  • If possible, costs are variable for taking
    account the new fuel cycle plants until the 2150
    time horizon, and they are decomposed in
    different stages (investment, operation,
    decommissioning)

31
The main economic assumptions common to all the
scenarios
Costs are calculated using different discount
rates constant annual discount rates 0,
3, 6, 8 variable annual discount rates
4 for cash-flows ? 30 years 2 for
cash-flows gt 30 years To guarantee continuous
values and eliminate "jumps" in the global costs
results, the discounting procedure is ? t ?
30 years, R 4, and C(t) (1R)-t ? t ? 31
years, R 4 et R' 2, and C(t) (1R)30 x
(1R')t-30

Concluding remarks
The work program will continue. I t will consist
in completing the prospective scenario by an
economic evaluation more robustly defined. Some
unit costs will have to be more robustly defined,
in particular for the innovative steps such as
advanced reprocessing, MOX-UE fuel
fabrication new industrial storages (for Am and
Cm) geological disposal Sensitive analysis will
have to be led on the more uncertain steps, for
example lifetime of current fuel cycle
facilities, construction, operation and
decommissioning schedule for future fuel cycle
plants.
