  • FEASIBILITY STUDY FOR AN ENGINEERING CONCEPT OF A STAINLESS STEEL - COPPER DIVERTOR PLATE PROTECTED BY TUNGSTEN-5% RHENIUM ALLOY OR GRAPHITE ARMOUR.

Abstract

THE SUBJECT OF THIS PAPER IS A DIVERTOR PROPOSED FOR THE PLASMA IMPURITY CONTROL SYSTEM FOR NET, WHERE HIGH FLUXES, MAINLY OF NEUTRONS AND IONS CROSSING THE MAGNETIC SEPARATRIX, DEPOSIT THEIR ENERGY. THE MATERIALS CONSIDERED ARE STAINLESS STEEL (AISI 316) FOR THE COOLING TUBES, PURE COPPER FOR THE HEAT SINK, TUNGSTEN-5% RHENIUM ALLOY OR GRAPHITE FOR THE PROTECTIVE ARMOUR. THE THERMAL AND THE MECHANICAL CALCULATIONS HAVE BEEN PERFORMED BY USING THE FINITE ELEMENT TECHNIQUE AND ASSUMING THE ASME CODE AS A GUIDE FOR THE DESIGN. SEVERAL GEOMETRIC AND MATERIAL RELATED EFFECTS HAVE BEEN TAKEN INTO ACCOUNT WITH PARTICULAR REFERENCE TO THE HEAT TRANSFER PERFORMANCE OF THE COMPONENT AND THE CONSEQUENT TEMPERATURE AND STRESS DISTRIBUTIONS. THE RESULTS OF THESE PRELIMINARY ELASTIC CALCULATIONS HAVE SHOWN THE ENGINEERING FEASIBILITY OF THE DIVERTOR FOR LOADING CONDITIONS SIMILAR TO THOSE OF NET DOUBLE NULL ASSUMED AS REFERENCE MAINFRAME.
