Introduction – Brazilian Energy Matrix
Renovation of the Energy Matrix
o Difficulties and uncertainties in a mainly hydropower system
o Need for securing energy supply and economic competitiveness
o Composition of a power supply based on a sustainable, diversified and competitive energy
o Increasing difficulties to increase the installed hydropower capacity (transmission lines, environmental challenges, low capacity factors…)

Introduction – Brazilian Energy Matrix Post-2030 Expansion
• Mix of Natural Gas, (depending on availability), Coal (depending on the
feasibility of clean carbon Technologies and economic viability) and Nuclear
(public acceptance and economic competitiveness)
• Renewable sources (biomass, wind and solar) and expansion of energy
efficiency programs will be an indispensable complement (water saving for dry
periods, felixibility, local solutions)

Introduction – Brazilian Energy Matrix
Uranium Reserves
• Currently the world’s 6th largest reserves
• Sufficient for 116 years, considering the current consumption (WEO 2006 – IEA)
• With reprocessing, this time frame is extended exponentially
Only 30% Prospected 309.000 tons

CAETITÉ
Availability and price stability for the nuclear fuel
Security against price volatility in the world Market
Technology on nuclear fuel fabrication

Introduction – Brazilian Energy Matrix Reasons for a Program of Nuclear Power Generation
o Long-term strategy to provide a supply of sustainable, diversified and competitive energy
o Introduction of advanced energy technologies of high performance and safety
o A Nuclear Power Program is an Industrial Project
o Productive capacity in Brazil and insertion in global value chains
o Economies of scale and gradual cost reduction

Angra 3 – Current Status
Limitations imposed to ELETRONUCLEAR’S cashflow due to the reduction of the Angra 1 and 2 tariffs, which led to a considerable revenue loss, prevented the company from providing the required counterpayments to make withdrawals from the external financing
Due to the above, ELETRONUCLEAR was forced to take exceptional measures:
Payment delays
Contract suspensions / Pace reduction
General Executive Schedule – commercial operation in 01.05.2019 -> already being reevaluated
Relevant Facts 2015
ELETRONUCLEAR
IAEA Technical Meeting Warsaw, February 2016 / Page 22
Angra 3 – Current Status
Similarity between Angra 3 and Angra 2 created extremely favorable expectations to its implementation
Unexpected difficulties found from the Project resumption onwards:
o Extremely complex contracts renegotiation processes
o New nuclear licensing requirements related to the use of new and/or updated codes and regulations
o Gradual authorizations from the licensing authorities for the release for concrete pouring services
o Licensing requirements for civil structures required independent revisions for structural calculations
Lessons Learned / Important Remarks
ELETRONUCLEAR
IAEA Technical Meeting Warsaw, February 2016 / Page 23
Angra 3 – Current Status
o Loss of capabilities and knowledge of the engineering companies, suppliers and construction/erection companies that performed works in the Angra 2 Project, due to the gap between the conclusion of Angra 2 and the resumption of Angra 3 (9 years!)
o Increasing number of Angra 2 Design Modifications that need to be included in the Angra 3 design
o Delays in the definition and availability of the required financing to support the contracting of import services and supplies
o Several “cannibalizations” during the Angra 2 electromechanical erection and commissioning stages and during Angra 2 outages (company decision due to Angra 3 uncertainties)
