Abstract

ACCIDENTS ARE CONSIDERED CONSISTING OF A BREACH IN THE VACUUM WALL OF A FUSION REACTOR, THE INGRESS OF AIR INTO THE TORUS AND MOBILISATION AND EXPULSION OF ACTIVATED ERODED-SPUTTERED MATERIAL. PREVIOUS EVALUATIONS ON NET, ASSUMING BARE PLASMA-FACING COMPONENTS, HAVE BEEN REVIEWED AND NEW ESTIMATES OF THE RATE OF MATERIAL DISCHARGE AND OF THE TOTAL FRACTION OF DISCHARGED MATERIAL ARE CALCULATED, INCLUDING RESETTLEMENT PROCESSES. THE CASE OF GRAPHITE-TILED WALLS, WITHOUT AND WITH COMBUSTION, IS ALSO EXAMINED. RADIOLOGICAL EVALUATIONS ARE THEN PERFORMED TO ASSESS THE HAZARD POSED BY THE DISCHARGED MATERIAL BOTH WITHIN THE NET BUILDING AND OUTSIDE IT.
