Uranium accountability for ATR fuel fabrication, a computer simulation

A stochastic computer model has been designed to simulate the material control system used during the production of fuel plates for the Advanced Test Reactor. The model is designed so that manufacturing process and measurement parameters are fed in as input. Changes in the manufacturing process and measurement procedures are easily incorporated. Individual operations in the plant are described by program subroutines. By using this model values for Inventory Difference (ID) and Limit of Error on Inventory Difference (LEID) may be calculated for predetermined plant operating conditions. Furthermore the effect on ID and LEID produced by changing plant operating procedures and measurement technique may also be examined

Acceleration of beam ions during major-radius compression in the tokamak fusion test reactor.

Tangentially coinjected deuterium beam ions were accelerated from 82 up to 150 keV during a major-radius compression experiment in the tokamak fusion test reactor. The ion energy spectra and the variation in fusion yield were in good agreement with Fokker-Planck code simulations. In addition, the plasma rotation velocity was observed to rise during compression. © 1985 The American Physical Society
