Study of Argentinian and Brasilian Nuclear Symbiotic Scenarios using CLASS
Résumé
The aim of this paper is to analyze and compare
nuclear scenarios including the Argentinian and the
Brazilian nuclear fleets working either in a collaborative
scenario or separately.
Brazilian nuclear fleet is composed of PWRs (Pressurized
Water Reactors). For
decades,
Argentina
has
been
operating
Pressurized
Heavy
Water
Reactors
(PHWR),
in
particular
a
Canadian
Deuterium
Uranium
(CANDU)
type
reactor.
Thanks
to
their
very
efficient
neutron
economy,
those
reactors
are
known
to
be
able
to
accept
large
spectrum
of
fuel
types.
They
can
be
critical
when
fueled
by
DUPIC
(Direct
Use
of
PWR
fuel
in
CANDU),
or
with
reprocessed
fuel
from
irradiated
enriched
uranium.
They
could
be
even
almost
breeders
if
used
with
thorium-‐based
fuels.
In
this
paper,
we
present
how
the
specific
reactor
physics
of
CANDU
have
been
implemented
in
the
scenario
code
CLASS
(Core
Library
for
Advanced
Scenario
Simulation).
Then
we
discuss
the
advantages
of
a
collaborative
scenario
between
Argentina
and
Brazil.
