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

Material, IAEA Safety Standards Series No. WS-R- 5, IAEA, Vienna (2006).

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

down other estimate similar plants. Is not based on

specific drawings or site information

• Budgetary -15% to +30% - PPD2018 - Based on system and building drawings, layouts and

equipment drawing for major components.

• Definitive -5% to +15% - Based on detailed building, system and equipment

drawings, characterization survey data, one line electrical

and system drawings and plot plants and elevation

drawings. Detailed review of scope and required activities

and their costs.

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.

Assumptions: • Experiences with the Transition from Operation to Decommissioning at NPPs on the U.S. (Kim &

McGrath, 2016)

>> 43,5% Human Resources - of the cost of the Decommissioning

• Actual Staff of Angra 1 operation and maintenance

• Medium Brazilian salary estimate + taxes and other tributes (still to be updated with

ETN real salaries)

• 3 to 5 years of Transition Period Duration

• Convervative estimative

5. IV - COST ESTIMATE FOR TPA1 – order of magnitude

Duração (meses) Total Cost TPA1 (order of magnitude) * 36 R$ 343.423.256 $ 105.668.694

48 R$ 457.897.674 $ 140.891.592

60 R$ 572.372.093 $ 176.114.490

>> Approximate staffing costs during transition period in U.S. - $25 Million/year

(Kim & McGrath, 2016)
