Nuclear in Brazil

Brazilian nuclear policy

What exists, what is missing — and the paradox of the largest country in the Southern Hemisphere with active tokamaks.

What is Brazil's nuclear policy?

It is the set of laws, institutions and programmes that define how Brazil researches, produces and uses nuclear technology — from uranium mining to power generation, from medicine to submarine propulsion. It is one of the most comprehensive nuclear policies in Latin America, but it faces serious challenges of funding and continuity.

How does it work?

  1. 1
    Guidelines

    The federal government and Congress set nuclear policy and budget.

  2. 2
    Regulation

    CNEN sets the standards, oversees compliance and grants operating licences.

  3. 3
    Fuel

    INB mines uranium and manufactures Brazil's nuclear fuel.

  4. 4
    Operation

    Eletronuclear runs the power plants; universities run the research tokamaks.

  5. 5
    Applications

    Electricity, medicine, industry, agriculture, research and defence.

Simplified flow — each stage involves several institutions and ministries.

Where does it have an impact?

Energy

Angra 1 and 2 generate about 3% of Brazil's electricity and more than 30% of Rio de Janeiro's electricity.

Medicine

Radiopharmaceuticals produced by IPEN support millions of diagnostic exams and cancer treatments each year.

Research

Three tokamaks (USP, INPE, UFES) and research reactors keep Brazil on the world plasma-science map.

Agriculture

Nuclear irradiation techniques improve seeds, control pests and extend food preservation.

Industry

Non-destructive testing, density gauges and radioactive tracers optimise industrial processes.

Defence

Naval nuclear propulsion — Brazil is one of the few countries that masters the full uranium cycle for peaceful military use.

What is still missing

Brazil has no stable public policy for nuclear fusion. Research depends almost entirely on CNPq, FAPESP and CAPES — all subject to budget cuts. There are not even consolidated figures on the total amount invested in fusion in the country.

Paradox: Brazil has the scientific foundations, uranium reserves (6th largest in the world) and qualified researchers. What is missing is a long-term political commitment.
