Abstract

SEVERAL LITHIUM-BASED COMPOUNDS ARE CURRENTLY BEING CONSIDERED AS BREEDING BLANKET POTENTIAL MATERIALS OF NET-TYPE FUSION DEVICES. AMONG THE MOST IMPORTANT ISSUES CONCERNING THESE MATERIALS ARE TRITIUM INVENTORY, RELEASE FROM THE BLANKET AND PERMEATION TO THE COOLING SYSTEM (IRP); IRP STRONGLY DEPEND ON TRITIUM DIFFUSIVITY D AND SOLUBILITY S IN THE MATERIALS INVOLVED. IN THIS PAPER THE STATE-OF-THE-ART IS ASSESSED : IN PARTICULAR, THE FOLLOWING ITEMS ARE CAREFULLY CONSIDERED : A) EXPERIMENTAL METHODS, B) UNCERTAINTIES AND/OR POSSIBLE ERROR SOURCES, C) MODELS USED FOR DATA ELABORATION. SUCH DATA SETS ARE SUBSEQUENTLY USED TO ASSESS IRP LEVELS IN FUSION REACTOR MODEL BLANKETS, BY MEANS OF CURRENTLY AVAILABLE ANALYTICAL MODELS AND, ALSO, MAKING USE OF APPROPRIATE NUMERICAL COMPUTER CODES. COMPUTATIONS ARE CARRIED OUT FOR THE NET-TYPE BLANKET/COOLANT CONFIGURATIONS. IN PARTICULAR, THE FOLLOWING TWO BLANKETS CONCEPTS ARE ACCOUNTED FOR : 1. WATER-COOLED POLOIDED MODULES, IE STRAIGHT U-SHAPED PRESSURE TUBES CONTAINING THE FLOWING LIQUID PB-17LI AND THE COOLING SYSTEM DUCTS, 2. POLOIDALLY HE-COOLED, BREEDER-OUTSIDE-TUBE, SOLID CERAMIC BLANKET, WITHE HE-PURGING CHANNELS IMBEDDED IN IT.
