1. Fusion Research Infrastructure
This chapter examines Brazil's fusion research infrastructure, which spans multiple institutions and includes both magnetic confinement fusion (MCF) and inertial confinement fusion (ICF) experimental capabilities. The analysis draws upon the network graph of 7 entities and 6 relationships, focusing on INPE, LAP, FN-II, ETE, NOVA-UNICAMP, and CNEN.
Brazil's fusion research ecosystem is more diverse than Argentina's, with multiple experimental devices operated across several institutions. However, all of these facilities are small-scale, university-level research installations oriented toward basic plasma physics research rather than fusion energy development at a competitive scale.
1.1 INPE and the Laboratory of Plasma Physics
INPE (Instituto Nacional de Pesquisas Espaciais, National Institute for Space Research, est. 1961) is Brazil's primary space and atmospheric research institution, which historically also managed the country's fusion research program. INPE's plasma physics activities are conducted through the Laboratory of Plasma Physics (LAP).
LAP (Laboratorio de Fisica de Plasma, est. 1978) at INPE operates the FN-II dense plasma focus device and conducts experimental plasma physics research. LAP has been a center for plasma focus studies, compact toroid research, and basic plasma physics investigations.
Key relationships:
- INPE operates LAP (since 1978)
- LAP operates FN-II (since 1978)
- CNEN receives program from INPE (institutional transition)
A significant institutional transition has occurred in Brazilian fusion research: management of the fusion program has shifted from INPE to CNEN (National Nuclear Energy Commission). This transition reflects the Brazilian government's decision to integrate fusion research more closely with nuclear energy oversight, partly in response to IAEA encouragement to bring fusion activities under nuclear safeguards authority.
1.2 FN-II Dense Plasma Focus Device
FN-II (est. 1978) is a dense plasma focus (DPF) device operated at INPE/LAP. The FN-II is a Mather-type plasma focus device designed for plasma physics research and neutron generation studies. Dense plasma focus devices produce short-lived, high-density plasma columns through the rapid compression of plasma by magnetic forces, generating intense bursts of neutrons, X-rays, and charged particles.
Key relationships:
- LAP operates FN-II (since 1978)
The FN-II is a small-scale research device with no weapons applications. Dense plasma focus devices are used worldwide for basic plasma physics research, neutron source development, and materials testing. While DPF devices can produce neutron bursts, the FN-II's output is orders of magnitude below what would be required for any weapons application. The device is used for fundamental research into plasma focus dynamics, neutron emission mechanisms, and plasma-material interactions.
1.3 ETE Tokamak
ETE (Experimento Tokamak Esferico, est. 2000) is a small tokamak facility at the University of Sao Paulo, representing Brazil's primary magnetic confinement fusion experiment. The ETE is a compact tokamak designed for basic plasma confinement studies, plasma transport research, and tokamak engineering development.
Key relationships:
- CNEN manages ETE (since 2000)
The ETE tokamak is a modest-scale device with plasma parameters well below those of major international tokamaks such as ITER, JET, or DIII-D. It serves as a training and research platform for Brazilian plasma physicists and engineers, providing hands-on experience with tokamak operations, plasma diagnostics, and magnetic confinement physics. The device is not capable of achieving fusion-relevant plasma temperatures or confinement times and has no weapons applications.
1.4 NOVA-UNICAMP Plasma Facility
NOVA-UNICAMP (est. 1996) is a plasma physics facility at the University of Campinas (Universidade Estadual de Campinas) conducting research on compact toroids and plasma physics. The facility provides additional experimental capabilities complementing the tokamak research at ETE and the plasma focus studies at LAP.
Key relationships:
- CNEN manages NOVA-UNICAMP (since 1996)
The NOVA-UNICAMP facility conducts research on compact toroid configurations, plasma formation and confinement, and basic plasma physics phenomena. Like the other Brazilian fusion facilities, it is a small-scale university research installation with no weapons applications.
1.5 CNEN: The Central Authority
CNEN (Comissao Nacional de Energia Nuclear, National Nuclear Energy Commission, est. 1956) is Brazil's nuclear authority, which has assumed management of the country's fusion research program. CNEN oversees nuclear fuel cycle activities, research reactor operations, radiation safety, and now fusion research coordination.
Key relationships:
- Receives program from INPE (institutional transition)
- Manages ETE (since 2000)
- Manages NOVA-UNICAMP (since 1996)
- IAEA Safeguards monitors CNEN (since 1957)
CNEN's assumption of fusion program management from INPE represents a significant institutional restructuring. This transition brings Brazil's fusion research under the same nuclear safeguards framework as the country's fission reactor programs, ensuring IAEA oversight of all nuclear-relevant research activities.
