Abstract :
Summary form only given. The effect of neutron streaming in the out-vessel maintenance inside of the primary shielding in IGNITEX has been analyzed by means of Monte Carlo techniques. The transport of neutrons and photons through diagnostic and vacuum penetrations during the IGNITEX pulse was simulated with the 3-D, MCNP numerical code. Various types of penetrations were considered, including maintenance ports (horizontal outboard access), horizontal diagnostic ports (horizontal outboard sight), and vertical diagnostic ports (vertical top/bottom sight). Shielding and design modifications for access piping to the IGNITEX machine were established on the basis of a multidimensional radiation analysis
