Objetivo THE USE OF HIGH PRESSURE ABRASIVE WATER JET CUTTING IN AIR FOR NON-RADIOACTIVE CONCRETE OR OTHER MATERIALS HAS BECOME A CURRENT PROCEDURE. THE APPLICATION OF THE ABOVE TECHNIQUE TO HIGHLY RADIOACTIVE METALLIC COMPONENTS UNDER THE PROTECTION OF A WATER LEVEL COULD BE VERY ATTRACTIVE FOR THE DISMANTLING OF NUCLEAR INSTALLATIONS, E.G. CUTTING OF CORE INTERNALS. THE PRESENT PROPOSAL IS AIMED AT DEVELOPING AND OPTIMISING - BY PARAMETRIC EXPERIMENTAL STUDIES - THIS TECHNOLOGY, THUS ALLOWING HIGH CUTTING PERFORMANCE WITH MINIMAL GENERATION OF SECONDARY WASTE BY ADOPTING A SET OF PARAMETERS SUCH AS WATER PRESSURE, WATER DEPTH, MASS FLOW OF WATER AND ABRASIVES, TYPE OF ABRASIVES. THE WEAR OF THE JET OUTLET NOZZLE AND THE ENERGY LOSS OF THE JET IN THE SURROUNDING WATER ARE CONSIDERED AS IMPORTANT ISSUES. 1. PREPARATION OF THE TEST FACILITY FOR UNDERWATER CUTTING. 2.. DEVELOPMENT AND FABRICATION OF THE ABRASIVE CUTTING HEAD. 3. STUDIES ON OPTIMISING THE WORKING DISTANCE AND MINIMISING FLOW RATES. 4. STUDIES ON THE INFLUENCE OF THE WATER DEPTH ON JET FORMATION AND CUTTING EFFICIENCY. 5. STUDIES ON THE INFLUENCE OF ABRASIVE MATERIAL ON JET FORMATION AND CUTTING EFFICIENCY.
