The success of process development can often be influenced by results and decisions made very early in evaluation process. The opportunity to evaluate new processes using commercially relevant equipment can assist in ensuring that raw material selection; initial processing steps; and assumptions regarding utilities consumption, product quality, and process yield will meet market requirements. Additional opportunities including obtaining equipment sizing data, matching process to equipment for maximized efficiency, and producing sufficient material for customer testing are realized when testing is performed in conjunction with the commercial scale equipment manufacturer. Involvement with key vendors at an early stage can be a critical factor. Availability of experimental data from laboratory testing provides a basis to design full-scale equipment that closely matches customer requirements. Risks associated with under-engineered solutions or high costs are minimized by the ability to use actual process data to design a thermal system.

Harper manufactures vertical free-fall reactors for a broad range of materials. As temperatures increase, the CAPEX becomes more important. It is important, therefore, to employ a modeling tool to properly size the equipment for the target production rate. The model is discussed, noting the simplifying assumptions and the rigorous algorithms. The model considers heavy particles (acceleration), semi-opaque clouds (efficiency vs. efficacy), collisions between particles in different size (or shape) families (in case sticking is anticipated), and temperature dependent properties of the gases and solids (to account for phase changes).

Harper International, Buffalo, N.Y., was recently awarded a contract for a pusher furnace line with Kepco Nuclear Fuel (KNF), which is currently producing nuclear fuel for its pressurized heavy water reactors. Over the past two years, Harper's Applications, Engineering, & Technology Groups have carefully developed an advanced heating system for KNF's pressurized heavy water reactors. With this sixth furnace for KNF and all furnace iterations, Harper continuously aims to advance equipment performance. In addition to the advanced heating element that allows for higher temperature operation, an enhanced furnace shell cooling design has been developed, and both yield longer uniform operational life cycles. Additionally, advances have been made in exit water cooling design, insulation designs that reduce ambient heat release, and energy usage. Harper is compliant with nuclear-specific control systems for mandated upgrades for increased security and reliability. "Harper's global leadership in nuclear fuel production system technology continues to be validated by clients, who place their trust in our staff to conceive and implement the world's most advanced, efficient and reliable sintering thermal processing systems," commented Tom O'Connor, Sales Manager at Harper International. "Further, Harper is pleased to partner with KNF on this project which will play a role in providing reliable energy without greenhouse gas emissions." In addition to nuclear material processing, Harper is a market leader in advanced Pusher systems for a wide range of materials, including metal oxides, powders, technical ceramics and energy device materials.

KNF provides nuclear fuel, equipment and related services to all nuclear power plants in Korea and customers in the global nuclear energy industry.
Harper International, Buffalo, N.Y, has been awarded a contract to supply a hot cell Rotary thermal processing system to treat waste from nuclear medicine production at the Australian Nuclear Science and Technology Organisation (ANSTO). Synroc technology has been developed to provide a safe, secure matrix for the immobilization and final disposal of radioactive waste. It will be utilized to encase radioactive wastes from the production of the radioisotope Molybdenum-99 (Mo-99), the isotope used for 80% of nuclear medicine procedures. This includes the diagnosis of cancers, heart disease, and muscular and skeletal conditions. The Rotary thermal processing system includes an advanced heating element design for increased robustness and ease of remote operation, and an enhanced modular design of components for ease of remote maintenance in a hot cell. "In addition to waste from nuclear medicine production, we foresee that this new technology can also benefit other applications in the future, such as processing spent fuel waste from other international power generating nuclear reactors," commented Dr. Prasad Apte, Director of Technology at Harper International. Along with waste remediation, Harper offers technology solutions such as Pusher and Rotary furnaces for nuclear materials processing applications, including sintering UO pellets for reactor fuel rods, oxidation of UO pellets, swarf, and powder to U O , denitration of uranyl nitrate, and hydrofluorination of UO pellets. ANSTO is one of Australia's largest public research organizations and is the center of Australia's nuclear science capabilities and expertise - operating the nation's only nuclear reactor, OPAL. Australian Mo-99 is produced with low enriched uranium (LEU) target plates in the LEU fueled OPAL reactor, leading the global push toward nuclear nonproliferation.
