Resumo
This paper presents the study and the structural analysis of the IEA-R1 primary
circuit piping supports, considering all the changes involved in the piping system
replacement conducted in 2014.
The IEA-R1 is a nuclear reactor for research purposes designed by Babcox-Willcox
that is operated by IPEN since 1957. The reactor life management and modernization
program is being conducted for the last two decades and already resulted in a series of
changes, especially on the reactor coolant system. This set of components, divided
in primary and secondary circuit, is responsible for the circulation of water into the
core to remove heat.
In the ageing management program that includes regular inspection, some degradation
was observed in the primary piping system. As result, the renewing of the
piping system was carried out in 2014. Moreover the poor condition of some original
piping supports gave rise to the refurbishment of all piping supports. The aim of the present work is to review the design of the primary system piping supports taking
into account the current conditions after the changes and refurbishment.
