Advanced Fuel Assembly R&D 

After decades of development, China has formed a complete technological system consisting of nuclear fuel assembly design, manufacturing and testing, built high-level R&D teams, and deployed advanced facilities for research and testing. To meet the needs of nuclear power development, and to claim the high ground in the development of nuclear fuel assembly technology, China is concentrating on R&D of large advanced PWR fuel assembly CF4 with the goal of 24-month refueling, which is known for high reliability, safety and economic efficiency. The research of annular fuel element has entered the engineering test stage. Research on accident tolerant fuel (ATF) is making steady progress. Research on high-performance nuclear-grade zirconium materials and other related materials has also made breakthroughs, laying an important foundation for research on new types of nuclear fuel assemblies. 

先進(jìn)燃料組件研發(fā)

經(jīng)過幾十年的發(fā)展，中國(guó)形成了核燃料元件設(shè)計(jì)、制造、試驗(yàn)等完整的技術(shù)體系，建立了高水平研究開發(fā)人才隊(duì)伍，建設(shè)了先進(jìn)的研究試驗(yàn)設(shè)施。為滿足核電發(fā)展的需求，提高核燃料元件的安全性、經(jīng)濟(jì)性，占領(lǐng)核燃料元件技術(shù)發(fā)展的制高點(diǎn)，中國(guó)以實(shí)現(xiàn)24個(gè)月?lián)Q料為目標(biāo)，研發(fā)具有高可靠性、高安全性、高經(jīng)濟(jì)性的CF4大型先進(jìn)壓水堆燃料組件；環(huán)形燃料元件研發(fā)進(jìn)入工程化試驗(yàn)階段；耐事故燃料元件（ATF）研發(fā)工作穩(wěn)步推進(jìn)；高性能核級(jí)鋯材及其它相關(guān)材料研發(fā)也取得突破，為新型核燃料元件研發(fā)奠定了重要基礎(chǔ)。
