Good practices in free release of materials resulting from the decommissioning of the VVR-S reactor

The paper aims to present the methodology used for free release of the materials arising from the VVR-S reactor decommissioning, as well as some practical examples for this methodology. From decommissioning process of a nuclear reactor are arising important quantities of materials which are potential radioactive wastes. The role of the free...

Radiological characterization of graphite from thermal column of VVR-S research reactor in view of intermediary storage

Our paper aims to presents the experiments which were performed in order to determine the 14'C and 3H accumulation during the functioning time of about 50 years in the thermal column of VVR-S reactor. A new facility and method for determination of tritium (^H or T) and radiocarbon (^''C) in incinerable solid wastes are described. The protocol...
