Design calculations for a neutron collimator for the TFTR

PDF Version Also Available for Download.

Description

Some of the design calculations for a collimator for TFTR application are presented and discussed. Discrete ordinates transport calculations have been completed for several right circular cylindrical stainless steel collimators using a 14-MeV neutron, isotropic, 30-cm radius disc source to approximate a plasma volume source. The collimators considered in these survey calculations consisted of 3-cm diameter columns centrally located in 60-cm diameter stainless steel cylinders that varied in length from 30 to 180 cm. The source-collimator-detector configurations consisted of the uniform disc source located 60 cm from the entrance of each collimator and a 6-cm diameter 6-cm long right circular ... continued below

The configurations were analyzed with the first collision source code GRTUNCL and the two-dimensional discrete ordinates code DOT III using an S/sub 4/ angular quadrature. (MHR)
