BRAZIL

Population: 202,7 million inhabitants

It is the fifth most populous country in the world

but with a low population density = 22inh/km2

São Paulo = 11,895 Rio de Janeiro = 6,453

Salvador = 2,902

Brasília = 2,852

Fortaleza = 2,572

Largest Cities

Population is made up of many

racial and ethnic groups. They are

descendant of indigenous peoples,

portuguese colonists, african slaves

and, since the 19th century, of

groups of immigrants. Portuguese is

spoken by all the population and

Brazil is the only portuguese

speaking nation in the Americas.

RMB PROJECT STATUS

� CNEN Institutes technicians developed the conceptual engineering design of the reactor systems and main facilities.

� Basic engineering design of systems, buildings and infrastructure of the RMB(except basic engineering design of pure nuclear systems and components).Brazilian company INTERTECHNE contracted. Ends in November 2014.

� Brazil-Argentina Agreement (CNEN-CNEA) for common basic engineeringdesign of the RMB and RA-10 (pure nuclear part). OPAL reactor in Australia asa reference. Argentinean company INVAP contracted. Ends in November 2014.

� Environmental licensing process started. Term of Reference for EIA approvedby IBAMA (environmental licensing authority). EIA done by BrazilianCompany MRS. EIA under analysis of IBAMA. Three public hearings done.1st License will be issued by December 2014

� Nuclear licensing process started. Site Evaluation Report is under analysis byDRS/CNEN (nuclear licensing authority)

FUKUSHIMA

ORGANIZATIONAL APPROACH TO FUKUSHIMA

Working groups of specialists under guidance of a Fukushima Response

Management Committee;

� gathering and evaluation of information about the accident onset,

development and consequences;

� identification of lessons learned applicable to Brazilian NPPs;

� safety assessments;

� establishment and management of an executive plan (studies and projects

consolidated in the ELETRONUCLEAR Fukushima Response Plan);

� participation in national and international discussion forums about the

lessons learned and safety initiatives.
