Limitations of 14 MeV Neutron Simulation Techniques

FOR THE TECHNICAL AND ECONOMIC FEASIBILITY OF FUSION POWER REACTORS THE FIRST WALL AND BLANKET MATERIALS MUST WITHSTAND 100 TO 300 DPA IN THEIR LIFETIME. PRESENT-DAY AVAILABLE MATERIALS ARE FAR FROM WITHSTANDING SUCH REQUIREMENTS. THEREFORE, IN PARALLEL TO THE DEVELOPMENT OF FUSION ENGINEERING REACTORS SUCH AS NET AND FER, A MASSIVE FUSION REACTOR MATERIALS TEST AND DEVELOPMENT PRO- GRAMME HAS TO BE FORWARDED THAT PRODUCES A VALID TECHNOLOGICAL DATA BASE FOR THE DESING OF A DEMONSTRATION REACTOR. IN THIS CONTEXT WE DISCUSS THE LIMITA- TIONS OF THE VARIOUS METHODS, PRESENTLY IN USE TO SIMULATE THE EFFECTS OF 14 MEV NEUTRONS, BASED ON THE USE OF SELF-ION, LIGHT-ION HIGH-ENERGY PROTON BEAMS AND FISSION NEUTRONS
