Abstract
Described is an overview of Neutron Transmutation Doping (NTD) silicon processing facilities in the OPAL reactor. A suite of six high capacity NTD silicon rigs have been developed and installed. Optimum quality of the arrays is achieved through rotation of the silicon in the rigs to ensure even neutron fluence. The innovative design features a simple combination of water bearing and drive/rotation utilising reactor pool water. A hydrostatic water bearing ensures that there is no physical contact between the single moving component and static rig housing during operation. This design overcomes many of the existing reliability and maintenance issues involved with typical mechanical drive systems. The resulting layout leaves the pool area clear of obstructions which might obscure vision and hinder target handling for operators. Ingot handling systems are also provided to ensure the safe and efficient transfer of silicon between pool-side and irradiation positions. © The Authors
