Resumo IPEN-doc 24576 Comissioning of the IEA-R1 nuclear reactor new heat exchanger2017 - CASTRO, A.J.A. de; UMBEHAUN, P.E.; CARVALHO, M.R.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.Resumo IPEN-doc 13628 Comissioning of the heat exchanger for the research nuclear reactor IEA-R12008 - CASTRO, ALFREDO J.A. de; CASSIANO, DOUGLAS A.; UMBEHAUN, PEDRO E.; CARVALHO, MARCOS R. de; FRAJNDLICH, ROBERTOArtigo IPEN-doc 13482 Comissioning of the new heat exchanger for the research nuclear reractor IEA-R12008 - CASTRO, ALFREDO J.A. de; CASSIANO, DOUGLAS A.; UMBEHAUN, PEDRO E.; CARVALHO, MARCOS R. de; FRAJNDLICH, ROBERTOArtigo IPEN-doc 19579 Commissioning of the IEA-R1 nuclear reactor new heat exchanger2013 - CASTRO, ALFREDO J.A. de; UMBEHAUN, PEDRO E.; CARVALHO, MARCOS R. de; FRAJNDLICH, ROBERTO; CASSIANO, DOUGLAS A.
