For sites with more than one facility, a site
strategy for decommissioning
shall be developed to ensure that
interdependences between the facilities
are
taken into account in the planning for
individual facilities that will lead to final
decommissioning plans for each facility
An important consideration when selecting
the decommissioning strategy
is the desired end state5 of the facility
following completion of the
decommissioning.
The preferred end state would be to
achieve a situation whereby the
site is released for unrestricted use (with or
without buildings) or a situation
whereby it may be released for restricted
use. Other end states could involve
partial release of a site or release of a site
under restricted conditions to control
its future use. The foreseen end states for
the three different strategies are
shown in Fig. 1.
The end state is defined as a
predetermined criterion defining the point
at which
a specific task or process (i.e.
decommissioning) will be considered

Decommissioning Strategies for Facilities Using Radioactive Material, SRS no 50. IAEA, 2007.
• Decommissioning: ADMINISTRATIVE AND TECHNICAL ACTIONS TO
ALLOW THE REMOVAL OF SOME OR ALL OF THE REGULATORY CONTROLS FROM A FACILITY (CNEN NN 9.01, 2012)
• With no unacceptable risk to the public, the workers or the environment
• Decommissioning Strategies for CNAAA:
Deferred Dismantling: Angra 1 and 2 NPPs
Immediate Dismantling: Angra 3 NPP
• Desired End State – Unrestricted use
• Important Issues
o Integrated National RW and SFAs Policy
o LLW / ILW Repository – under siting selection phase
o HLW and SFA Repository – waiting for political decision

Unplanned / Prematurely Shutdown - Decommissioning:
I.Voluntary Decision: ETN must meet the requirements laid down by the Regulator Agency in
order to ensure safe implementation of early decommissioning process of the Nuclear Facility and present the financial guarantee for the accomplishment of this activity.
II.Government action: I The Govern must complement the Decommissioning Trust Fund
(DTF)
III.Accident: US$ 500 million issurance for each plant to promote early decommissioning of the
plants.

Fill a detail Gap in the PDP of CNAAA and to attend a requirement of CNEN.
Reasons for Delay and Financial Trouble / Loss in the Transition Period (IAEA, 2004):
I. Unavailability of funds;
II. Early, unplanned and permanent shutdown of a plant - political, regulatory or
economic reasons;
III. Lack of a decommissioning strategy; Lack of infrastructure (Intermediate or Final
Repository) or technology;
IV - Lack of regulation for decommissioning;
V. Loss / demotivation of key people and adaptation to cultural changes;
VI. Lack of planning for the decommissioning made during the operation of the plant.
