Approaches to the Characterization of Graphite UGR Blocks Based on Beta-emitting 14С and 36Сl Radionuclides. Testing at RBMK-1000-type Reactors

Abstract

This paper presents some methodological approaches to the characterization of graphite blocks based on difficultto-measure 14C and 36Cl radionuclides during graphite stack dismantlement at uranium-graphite reactors (UGR) developed by JSC PDC UGR. It presents the testing results of the developed methods applied during RBMK-1000 graphite stack block characterization at the Leningrad NPP.
