Decommissioning and dismantlement of nuclear power plants (NPP) present the final phase of a nuclear power plant  lifetime and are an essential part of an efective nuclear safety culture. While some countries are implementing nuclear  exit strategies and others are building new nuclear power plants or prolonging their lifetimes, the decommissioning of  facilities is imminent. This paper gives a short overview on decommissioning and dismantling strategies and techniques  as an introduction to the applicability of radioactive metal waste recycling and reuse. General estimations suggest that  the majority of the waste mass resulting from decommissioning and dismantling is radiologically unrestricted material  i.e. exempt waste. The remaining one-third is the radioactive material with different levels of radioactivity. To present  radioactive metal scrap recycling in practice, this paper addresses estimations on metal waste amounts resulting from  decommissioning, the use of melting as a possible recycling method (with regard to secondary waste generated) and  aspects of environmental and health impacts. Additionally, the best practice example of the decommissioning process in  a pressurized water reactor (PWR) with NPP technology is given to provide context for the possible future decommissioning  of NPP Krsko. After consideration of the available data on decommissioning waste management, the conclusion  is that while the decision on decommissioning strategies and technologies is not straightforward but unique to each  country, current experiences give important context to the complexity and potential of decommissioning and provide a  basis for future actions.
