To develop the application of 95 Nb as an indicator of redox potential for fuel salt in molten salt reactor (MSR), the specific activity of 95 Nb in FLiBe salt and its deposition of 95 Nb on Hastelloy C276 have been studied. Experimental results indicated that the amount of 95 Nb deposited on Hastelloy C276 resulted from its chemical reduction exhibited a positive correlation with the decrease of 95 Nb activity in FLiBe salt and the relative deposition coefficient of 95 Nb to 103 Ru appeared a well correlation with 95 Nb activity in FLiBe salt. Both correlations implied that the measurement of 95 Nb activity deposited on Hastelloy C276 specimen might provide a quantitative approach for monitoring the redox potential of fuel salt in MSR.

基于Hastelloy C276上95Nb沉积的燃料盐氧化还原电位监测新方法

为了开发95 Nb作为熔盐反应堆（MSR）中燃料盐氧化还原电位指标的应用，已经研究了FLiBe盐中95 Nb的比活及其在Hastelloy C276上的95 Nb沉积。实验结果表明，化学还原法在哈氏合金C276上沉积的95 Nb量与FLiBe盐中95 Nb活性的降低呈正相关，相对于95 Nb的95 Nb与95 Nb的相对沉积系数呈现出良好的相关性。 FLiBe盐中的活性。两种相关性都暗示对沉积在Hastelloy C276标本上的95 Nb活性的测量可能为监测MSR中燃料盐的氧化还原电位提供了一种定量方法。
