Resumo
IEA-R1 is a research reactor developed by Babcock & Wilcox and operating in
IPEN – CNEN/SP since 1957. The core of the reactor is located 7 meters below
the swimming pool water level and mounted over eighty holes supporting plate. Over
theses holes fuel and control elements, guides, and other structures are located, displaced
in a way to optimize experimental arrangements. The main plate is supported
by a frame that is connected to an overhead crane through aluminum profiles. This
work evaluates the support structure of the core and estimates its service life, taking
into account the deformation of the aluminum alloy 6061 T6 due to a critical
integrated neutron flux of 0:5 1022 neutrons per cm2. Considering the reactor
neutron flux as the main life criteria to the aluminum profiles that support the core
structure, we evaluate the remaining working hours of the frame. It also estimates
the consequence of a change in the reactor power from 2 MW to 5 MW. Future
works should include a visual inspection and an evaluation of the frame materials
