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

The production of low-energy neutrons for the RHMMS

Neutron interrogation is used in both the active neutron measurement cell for the identification of fissile materials and in the hazardous material cell for the capture gamma identification of the hazardous elements in waste. The use of radiological neutron sources and neutron generators, using the deuterium/tritium or deuterium/deuterium reactions for neutron production, results in the production of high energy neutrons. For most materials the high absorption cross sections are in the neutron thermal energy range. The moderation of the high energy neutrons to provide a high ratio thermal/epithermal spectrum is difficult. The effort herein reported seeks to find methods of producing neutrons at much lower energy levels, preferably below 200 KeV. 1 ref., 2 tabs

Programmable multi-timer for TRU waste analysis applications

A programmable, multiple-function timing module has been developed for use in transuranic (TRU) waste analysis applications at the Idaho National Engineering Laboratory. The Programmable Multi-Timer (PRMT) is an expanded version of a module originally built for accelerator-based active photon interrogation experiments. During the course of the experiments, it became obvious that a more versatile timer was needed to meet several unforeseen requirements. The PRMT was designed to meet the new requirements and to serve as a general-purpose timing module for other applications
