ActiveSpecification for sintered natural uranium dioxide pellets for PHWR plant
重水堆核电厂燃料元件用烧结天然二氧化铀芯块技术条件
Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and packaging for sintered natural uranium dioxide pellets used as nuclear fuel in pressurized heavy water reactor (PHWR) plants. It is applied in the manufacturing and quality control of fuel elements for PHWR power stations, ensuring the pellets meet dimensional, density, chemical purity, and microstructural criteria for safe and efficient reactor operation. The standard is critical for fuel fabrication facilities and nuclear regulatory bodies in China to certify fuel integrity and performance under reactor conditions.
