Resumo
The successful development of energy-conversion machines based on either nuclear
fission or fusion is completely dependent on the behaviour of the engineering materials used to
construct the fuel containment and primary heat extraction systems. Such materials must be
designed in order to maintain their structural integrity and dimensional stability in an
environment involving high temperatures and heat fluxes, corrosive media, high stresses and
intense neutron fluxes. However, despite the various others damage issues, such as the effects
of plasma radiation and particle flux, the neutron flux is sufficiently energetic to displace atoms
from their crystalline lattice sites. It is clear that the understanding of the neutron damage is
essential for the development and safe operation of nuclear systems. Considering this context,
the work presents a study of neutron damage in the Gas Cooled Fast Transmutation Reactor
(GCFTR-2) driven by a Tokamak D-T fusion neutron source of 14.03 MeV. The theoretical
analysis was performed by MCNP-5 and the ENDF/B-VII.1 neutron data library. A brief
discussion about the determination of the radiation damage is presented, along with an analysis
of the total neutron energy deposition in seven points through the material of the plasma source
wall (PSW), in which was considered the HT-9 steel. The neutron flux was subdivided into
three energy groups and their behaviour through the material was also examined.
