A neutronic analysis of the KSTAR Tokamak

Summary form only given, as follows. Summary form only given. High-beta, beam-heated KSTAR deuterium plasmas should produce fusion neutrons. There are two competing DD fusion reactions in a deuterium plasma, one ejects 2.45 MeV neutrons, and the other produces tritons, which are confined in the plasma and undergo D-T reactions producing 14.1 MeV neutrons. The KSTAR Tokamak is under construction now. This study of MCNP calculation is mainly for the calibration of neutron detectors in KSTAR neutron diagnostics system with given geometry. The MCNP calculations should be made for no water in the KSTAR Tokamak water jacket, for water in the jacket and for water and boron in the jacket. The biological dose, nuclear heating of the cryogenically cooled magnets, and neutron activation of the surrounding materials would be investigated additionally in this work.
