Resumo: The low-level radioactive waste produced in Instituto de Engenharia Nuclear is generated basically from three distinct nodes: a particle accelerator (CV-28 Cyclotron), radiochemistry laboratories and the oneration of a nuclear research reactor (Argonaut type). In the Cyclotron unit, all water flow from hot labs as well as from the decontarciantion laundry is retained in special tank with homogenizing system and a remote control, that signalizes when the tank gets a pre-specified level. Samples homogenized from the tank are colected for previous analysis. They are analised and the possibility of sewerage disposal is evaluated. In the radiochemistry units the radiological protection service maintains recipients for collecting all radioactive wastes which are irainly low-level alpha radioactive wastes. In the reactor unit some radioactive material generated by fission migrates from the fuel out to the coolant system and is retained in a filtration and ion-exchange resin system. Noble gases which migrates to air from cooling water is measured and exhausted from the building reactor in a very low concentration. This work presents in details the control, treatment and disposal of the radioactive waste of above units.
