Nuclear design calculations for the TFTR neutral beam injectors

PDF Version Also Available for Download.

Description

The results of two-dimensional neutronics calculations aimed at identifying the nuclear responses that affect the performance of vital components are summarized. The neutral beam injector assembly was modelled using r-z geometry with cylindrical symmetry about z-axis. The dimensions and compositions of the components were taken from engineering drawings and sketches. The neutron source strength was assumed to be composed entirely of 14-MeV neutrons isotropically emitted from an area having a radius of 70 cm. The total neutron yield from the reactor was 7 x 10/sup 18/ neutrons/second. The radiation transport calculations were performed using the two-dimensional discrete ordinates code DOT ... continued below
