摘要:

福島核事故之后，現(xiàn)有核電站面對重大事故的固有安全性不足還是引起了世界核能研究領(lǐng)域的高度重視，事故容錯燃料（accident tolerant fuel, ATF）的概念也由此產(chǎn)生。事故容錯燃料能夠在較長時間內(nèi)抵抗冷卻劑喪失事故，還能保持或提高正常工況下的性能�？紤]到二氧化鈾（UO2）是目前在核反應(yīng)堆中得到大規(guī)模應(yīng)用的核燃料，在不影響UO2中子特性的前提下提高其熱導(dǎo)率成為近期最有可能得到應(yīng)用的技術(shù)。因此，在眾多事故容錯燃料體系中，UO2基事故容錯燃料成為目前研究的重點。主要針對目前UO2基事故容錯燃料芯塊的研究進(jìn)展進(jìn)行了綜述。

Abstract:

The safety of current nuclear plant has attracted more and more attention since Fukushima earthquake in Japan which generated serious accident of nuclear reactors. Thus the concept of accident tolerant fuel (ATF) was suggested, which could keep resistance to loss of coolant accident and improving the performance under normal working condition. Among the several materials of ATF, uranium dioxide (UO2) based fuel which enhances the thermal conductivity without affecting the neutron property has been considered the most significative frame fuel applied in current nuclear reactors. As a result, UO2 based ATF has also been considered the most important currently. In this paper the research progress of UO2 based ATF has been reviewed.
