Fixed Bed Nuclear Reactor
April 28 – May 2, 2008
Criticality of FBNR Reactor
There are two sources of heat generation in a nuclear
The reactor safety requires that the fission process be under control and the cooling of residual heat due to the decay of fission products is achieved by natural convection
Passive cooling is obtained by cooling through the phenomena of natural convection.
Variation in global temperature.

Proliferation resistance is that characteristic of a nuclear system that impedes the diversion or undeclared production of nuclear material, or misuse of technology, by States in order to acquire nuclear weapons or other nuclear explosive devices.
Como II, IAEA STR-332, December 2002
Intrinsic proliferation resistance features are those features that result from the technical design of nuclear energy systems, including those that facilitate the implementation of extrinsic measures.
Extrinsic proliferation resistance measures are those that result from States’ undertakings related to nuclear energy systems.
Safeguards is an extrinsic measure comprising legal agreements between the party having authority over the nuclear energy system and a verification control authority (e.g. IAEA or a Regional Safeguards System)

How a small investment by an investor/country can raise a large capital for the project through a multi national program.
CRP- IAEA Coordinated Research Project, the embryo of
WONEC – World Nuclear Energy Company
Leverage of Fundos for WONEC
European Community’s “Matching Fund”
20 countries participate in the Projeto
Therefore, an investment of $ 1.00 raises $ 100.00 for the project.
The technology should be available to all the nations of the world under the supervision and control of the international authorities such as IAEA.
FBNR meets the requirements of the IAEA's INPRO standards as a future reactor:
The benefits of the project for a country
Energy without causing global warming.
High technology development.
Avoid brain drain
Influence of high technology on other Industries.
Transfer of the present knowledge on FBNR to a group of researchers can be done through
Teaching at distance
