Retrieval of nuclear waste canisters from a borehole
Borehole disposal of spent nuclear fuel (SNF) and high-level waste (HLW) uses off-the-shelf directional drilling technology developed and commercialized by the oil and gas sectors. It is a technology that has been gaining traction in recent years in the nuclear industry. Disposal can be done in one or more boreholes (including an array) drilled into suitable sedimentary, igneous, or metamorphic host rocks. Waste is encapsulated in specialized corrosion-resistant canisters, which are placed end to end in disposal sections of relatively small-diameter boreholes that have been cased and fluid-filled. After emplacement, the vertical access hole is plugged and backfilled as an engineered barrier.

The Tritium Emissions Reduction Facility (TERF) is an automated process that continuously removes tritium from process gases before they are discharged to the atmosphere. Key control parameters include: temperature, pressure, flow, oxygen content, total combustibles, moisture concentrations and tritium concentrations. The procurement of an industrial, microprocessor-based Distributed Process Control System was justified for TERF due to the critical nature and complexity of the system. A detailed performance specification was prepared and submitted to industrial companies who had demonstrated past success in the field of process control and instrumentation. The contract was awarded to the Foxboro Company, of Foxboro, Ma., who developed the new Intelligent Automation (I/A) Distributed Process Control System. A primary goal of the design team was that the control system increase TERF reliability and availability by automatically controlling system operation and by assisting the operator in the diagnosis of problems, preventative maintenance, alarming, report generation, and long term storage of data. The comprehensive continuous monitoring of the TERF process provided by the Foxboro I/A Distributed System is expected to: (1) optimize the system operating parameters and control the process better than was previously possible, (2) provide more alerts and alarms to aid operators in diagnosing and responding to problems, and (3) record and organize process data more effectively than before.
