Abstract: The Brazilian Nuclear program has progressed in the past 60 years, resulting in six reactors, being four nuclear research reactors and 2 nuclear power plants. There is one more NPP under construction. With the establishment of the Brazilian Nuclear Energy Commission CNEN (Comissão Nacional de Energia Nuclear), in 1962, it was possible to tandardize the use of nuclear energy for...

Risk management process is a matured process that has been widely applied in various industries. The application of this process in Decommissioning and Dismantling has been limited. In the past few years the International Atomic Energy Agency (IAEA) launched a 4 year international project on Decommissioning Risk Management (DRiMa) with the objective of providing guidelines on how to implement...

The aim of safety assessment is to identify possible safety hazards related to planned activities of the NPP decommissioning, to identify possible operational events and their assumed consequences to personnel and public. Moreover it is necessary to demonstrate that in the case of the most serious assumed operational events, consequences will be mitigated by defined manner and any...

Metallic solid radioactive waste is the main type of radioactive waste generated from decommissioning operations. Transport, storage and disposal regulations require for gamma emitting radioactive waste ( mainly by Cs-137 isotope), that the dose rate in the proximity of the container should stand below a certain threshold. Also, the conditioning technique ( using cementation technique ) based...

Abstract: Nuclear decommissioning is an increased industrial activity in nuclear fuel cycle facilities owing to the fact that some of the nuclear installations have outlived its usefulness and hence remained under permanent shutdown. These facilities require safe decommissioning and subsequent restoration of site to general use. In order to facilitate this activity, IAEA is rendering all...
