Abstract

AS A PART OF THE SAFETY ANALYSIS OF THE MAGNET, THREE QUENCHES HAVE BEEN INITIATED IN ONE OF THE TF COILS IN SACLAY TEST FACILITY. WHILE TRANSPORTING A GIVEN CURRENT, THE COIL IS INSULATED FROM THE REFRIGERATOR : THE TEMPERATURES OF THE HELIUM AND OF THE COIL INCREASE SLOWLY ON ACCOUNT OF THERMAL LOSSES. AT THE CURRENT SHARING TEMPERATURE A QUENCH RAPIDLY PROPAGATES AND THE PROTECTION SYSTEM MAKES THE COIL DISCHARGE IN THE DUMP RESISTOR. AT THREE LEVELS OF CURRENT ELECTRICAL, THERMAL AND HYDRAULIC MEASUREMENTS HAVE BEEN PERFORMED. ALL THESE RESULTS ARE TAKEN INTO ACCOUNT FOR THE SAFETY DESIGN OF TORE SUPRA. BY THESE TESTS, IT HAS BEEN POSSIBLE TO CHECK THE GENERAL SAFETY CONCEPTION OF TORE SUPRA ON A MODEL OF THE SAME SIZE. IN PARTICULAR IT HAS BEEN DEMONSTRATED THAT THE ENERGY EXTRACTION IN CASE OF QUENCH WAS FAST ENOUGH TO LIMIT THE PRESSURE INCREASE INSIDE THE VESSEL TO AN ACCEPTABLE LEVEL.
