Resumo
This work presents results on the commissioning of the new heat exchanger of
the IEA-R1 nuclear reactor in the occasion of its operational power upgrade from 2
MW to 5 MW, in comparison to the values calculated in the project of IESA Design
and Equipments Company. This reactor is a swimming pool type, light water
moderated and with graphite reflectors, used for research purposes and medical radioisotopes
production. During monitoring procedures, issues were observed on the
reactor operation at 5 MW mainly due to the ageing of the reactor’s oldest heat
exchanger (TC-A) and excessive vibrations at high flow rates on the other installed
heat exchanger (TC-B). So it was decided to provide a new IESA heat exchanger
with 5 MW capacity to definitely substitute the TC-A heat exchanger. The results
show that the IEA-R1 nuclear reactor can be operated safely and continuously at 5
MW with the new IESA heat exchanger.
