Abstract

Abstract : For a long time, nuclear fusion has been anticipated to become a future power source. The International Thermonuclear Experimental Reactor (ITER) tokamak is designed to demonstrate the feasibility of applying the deuterium-tritium fusion reaction to human power needs. The measurements of ITER's fusion neutron flux parameters can provide information on total fusion power and fusion power density as well as other plasma parameters. This paper gives an overview of the technical constraints in terms of the radiological, thermal, and electromagnetic loads for ITER neutron detectors. These constraints have been studied and summarized with measurement requirements. The areas of high risk have been highlighted to encourage research and development of neutron detectors for the urgent needs of ITER.
