Spatial distribution studies of activation radionuclides in graphite of uranium-graphite reactors

The paper presents the results of studies of the spatial distribution of radionuclides¹⁴C,³⁶Cl and⁶⁰Co, which are key for decommissioning uranium-graphite reactors, in graphite stacks and individual graphite blocks. The studies were carried out on a shutdown PUGR ADE-5 of «PDC UGR» JSC, which provides access to the graphite stack with the ability to extract individual graphite blocks. Based on the results of a detailed experimental study of graphite blocks retrieved in 2018, the new interpretations of some features of the spatial distribution of radionuclides in UGR graphite was proposed.
