Material Accountancy System at a New Automated Mixed-Oxide Facility: PFPF

Conference · · Transactions of the American Nuclear Society
OSTI ID:5493733
At conventional mixed-oxide (MOX) fuel fabrication facilities, the personal radiation exposure of operators increases in proportion to the amount of plutonium to be handled. To resolve this issue, automated techniques in high-level radiation areas have been introduced at Japan's new MOX facility, the plutonium fuel production facility (PFPF). The PFPF incorporates a fully automated operating scheme into the main process and storage areas. Unlike conventional MOX fuel fabrication facilities, operators do not need direct access to nuclear material during normal plant operation. To achieve process control including criticality safety, PFPF has introduced an on-line computerized advanced accountancy system (AAS), which is capable of obtaining all inventory information throughout the entire facility in detail. The AAS can acquire material accounting data from equipment installed in each storage unit. All materials in the process areas are itemized as each transfer container is moved, and each container is measured at internal measurement points between a glovebox and any intermediate storage unit. The AAS can acquire material accounting data from information on the amount of nuclear material transferred. Thus, all material accounting data are obtained automatically by management on a real-time basis.
