摘要

先进压水堆压力容器下封头采用材料为低碳钢SA508，其表面容易氧化，可能对堆内熔融物滞留（IVR， in-vessel retention）策略临界热流密度（CHF，critical heat flux）产生显著影响，从而影响该策略安全余量。针对这一问题，本文首先研究了低碳钢SA508不同程度表面氧化对加热面朝下CHF的影响，其次研究了在低碳钢表面氧化情况下纳米流体强化CHF效果。结果发现，低碳钢SA508表面氧化对加热面朝下池式沸腾CHF具有显著影响，随着氧化程度的加深，CHF快速增长并最终达到稳定，表面完全氧化情况下CHF稳定值是表面轻微氧化情况下的2倍左右；将完全氧化低碳钢表面放入纳米流体中进行沸腾实验，发现纳米流体可以继续提高完全氧化表面CHF但效果大幅减弱，CHF增强原因在于表面纳米颗粒沉积层具有很强的吸水性。

Abstract

The material used for the lower head of the advanced pressurized water reactor pressure vessel is low-carbon steel SA508. The surface of SA508 is easy to oxidize， which may have a significant impact on the Critical Heat Flux （CHF） of the In-Vessel Retention （IVR） strategy， thus affecting the safety margin of the strategy. In this study， the influence of the different degrees of surface oxidation on CHF of low-carbon steel SA508 was first investigated through experiments. Then the CHF enhancement effect of nanofluid was studied under the condition of surface oxidation of low-carbon steel. It was found that the surface oxidation of low-carbon steel SA508 significantly affected the CHF in downward-facing pool boiling. With the deepening of the oxidation degree， CHF increased rapidly and finally reached stability. The stability value of CHF under complete surface oxidation was about two times that under slight surface oxidation. Boiling experiments were carried out on the surface of fully oxidized low-carbon steel in a nanofluid. It was found that the nanofluid could continue to increase the CHF of the fully oxidized surface， but the effect was significantly reduced. The increase in CHF was due to the water absorption ability of the surface nano-particle deposition layer. The results may help determine the actual safety margin of IVR and which is the effective enhancement method.
