1 Regional Trainning Course In Nuclear Facility Decommissioning and Environmental Remediation Skills 4 15 April 2011 Argonne National Laboratory, Argonne, IL, USA Roges de Oliveira National Nuclear Energy Commission - CNEN BRAZIL

2 Roges de Oliveira Country: Brazil Organization: National Nuclear Energy Commission - CNEN Type: Regulatory Agency, Development and Research Position: Researcher/Technical adviser (Occup. Rad. Prot.) Department: Coordination of Nuclear Fuel Cycle Facilities Technical background: - Physicist and D.Sc. on Nuclear Engineering - Five years experience on licensing nuclear fuel cycle facilities - Expert on occupational radiological protection Main interest in attending this course: - Acquire skills and knowledge, on radiological protection to be applied to the future Decontamination and Decommissioning and Environmental Remediation of nuclear fuel cycle facilities.

3 Summary of Decontamination and Decommissioning (D&D) and Environmental Remediation Issues and Challenges Operating facilities that involve radioactive materials: - Nuclear power plants (2) and 1 in construction - Eletronuclear - Uranium mining and milling (2) - INB - Nuclear fuel cycle facility: INB(1) industry Navy(2) development - Nuclear material storage facility (2) INB (USIN, Botuxin) - Research reactor (4) - CNEN - Waste repository - (Radiological Accident in Goiania, 1987) - Radioactive installations (3750) - medical, industry, research and education - NORM producing industries - Mining, Oil and gas, rare-earth

4 Summary of Decontamination and Decommissioning (D&D) and Environmental Remediation Issues and Challenges Eletronuclear - Nuclear Power Plants Angra dos Reis/RJ Angra 3 site Angra 2 Angra 1

Cycle Facilities Industries - Resende/RJ FCN 1 Fuel Element

5 Summary of Decontamination and Decommissioning (D&D) and Environmental Remediation Issues and Challenges INB Fuel Cycle Facilities Industries - Resende/RJ FCN 1 Fuel Element Factory FCN 2 - Conversion and Pellet Fabrication FCN 3 - Enrichment

6 Summary of Decontamination and Decommissioning (D&D) and Environmental Remediation Issues and Challenges INB - Uranium Mining and Milling Caetité/BA INB - Uranium Mine INB Uranium Milling

7 Summary of Decontamination and Decommissioning (D&D) and Environmental Remediation Issues and Challenges INB - Uranium Mining and Milling Poços de Caldas/MG

8 Summary of D&D and Environmental Remediation Issues and Challenges Regulatory framework in Brazil: - Federal Constitution - Government: Electric power generation; nuclear fuel cycle; regulating, licensing and controlling nuclear safety and environmental protection - Federal/State/Municipality Laws - Regulations - CNEN Nuclear regulations establish the need for decommissioning But no detailed decommissioning regulation has been established Regulators expertise: - Experience on decommissioning a monazite sands processing plant USAM

9 Summary of D&D and Environmental Remediation Issues and Challenges D&D activities in Brazil - Facilities already decommissioned: USAM (1998) - Processing plant for monazite sands with Th and U associated - Facilities scheduled for decommissioning in near future: CIPC - Uranium mining and processing plant

10 Summary of D&D and Environmental Remediation Issues and Challenges Decommissioning of the Santo Amaro facility USAM Before After (1999)

11 Summary of D&D and Environmental Remediation Issues and Challenges Decommissioning of the Santo Amaro facility USAM TODAY

12 Summary of D&D and Environmental Remediation Issues and Challenges Sites that may result in radiological environmental contamination - Uranium mining and processing: URA - Caetité/BA (in operation) CIPC - Poços de Caldas/MG (suspended operation) USIN - São Paulo/SP (Nuclear storage facility) - NORM facilities Form of environmental contamination: - Soils, surface water, groundwater

13 Challenges and Issues Major challenges and issues related to D&D and/or environmental remediation in Brazil - Project management - limited experience (only USAM) - Regulatory uncertainty - Regulator expertise - limited experience (only USAM) - Public stakeholder concerns - Funding resources - Lack of waste disposal facilities
