摘要:

日本福島核事故后，以提升核反應(yīng)堆事故工況下安全性為目的的事故容錯燃料技術(shù)成為了世界范圍內(nèi)研究的熱點。包殼涂層技術(shù)是事故容錯燃料短期規(guī)劃的主要方向，在鋯合金燃料包殼表面制備防護(hù)涂層能夠在不改變現(xiàn)有核包殼管元件產(chǎn)業(yè)鏈的前提下，有效提升失水事故工況下鋯合金包殼的事故容錯能力。納米多層涂層由于其固有的特征尺寸效應(yīng)和界面效應(yīng)，表現(xiàn)出了優(yōu)異的核性能，以及在事故容錯燃料包殼涂層材料領(lǐng)域的巨大應(yīng)用潛力。綜述了近年來國內(nèi)外鋯合金包殼表面納米多層涂層的研究進(jìn)展，主要包括多層涂層的分類、制備技術(shù)及服役性能，同時總結(jié)了納米多層涂層的性能優(yōu)勢及應(yīng)用前景，并對其未來發(fā)展前景進(jìn)行了展望。

Abstract:

After the Fukushima nuclear accident in Japan, the accident-tolerant fuel (ATF) technology for improving the stability and security of nuclear reactors at the loss-of-coolant accident conditions has been a research focus across the world. The cladding coating technology is the main heading direction of ATF in the short-term planning. Without changing the industrial chain of current nuclear cladding tube, the zirconium alloy cladding coated with protective coating can effectively improve the capability of accident tolerance at the loss-of-coolant accident conditions. Due to the inherent size effect and interfacial effect,nanolaminated coatings exhibit excellent nuclear performance, and are regarded as a kind of potential ATF cladding coating materials. This paper reviewed the recent progress in research on nanolaminated coatings on the surface of zirconium alloy cladding, mainly including the category, preparation technology and service performance of nanolaminated coatings. Moreover, the performance advantage and application prospect of nanolaminated coatings were summarized with prospecting the future development.
