Abstract Recent investigation into designs of molten salt reactors (MSR) requires accurate data of candidate salts. Review of the literature shows lacking thermophysical (TP) property data for coolants and fuel-bearing salts of Advanced High Temperature Reactors (AHTR). Measurement uncertainties of current data are even more deficient, and this affects ongoing research where MSR modeling and testing are being performed. Melting temperature, viscosity, density, specific heat capacity, and thermal and electrical conductivity measurements are often not arranged together or discussed in great detail, especially for fuel-bearing salts. Raw data from key findings spanning over 70 years for LiF, LiF-BeF2, LiF-NaF-KF, KCl-MgCl2, KF-ZrF4, and NaF-KF-MgF2 have been organized and presented here. Brief description of methods used to obtain these results, in addition to the TP data of some of these salts as fuel carriers, has also been discussed. Thermal conductivity data are particularly weak due to older, high-error measurement techniques. More recent measurement systems to evaluate salt thermal conductivity show promise for obtaining consistent absolute values. This paper concludes that measurement systems such as transient hot-wire method, forced Rayleigh scattering, and laser flash analysis provide the most promise to fill these data gaps and reduce current uncertainty in thermal conductivity measurements of both fueled and un-fueled molten salts.

应用于燃料和非燃料熔盐的热物性方法综述

摘要 最近对熔盐反应堆 (MSR) 设计的研究需要候选盐的准确数据。文献回顾表明，缺乏先进高温反应堆 (AHTR) 的冷却剂和含燃料盐的热物理 (TP) 特性数据。当前数据的测量不确定性更加不足，这会影响正在进行的 MSR 建模和测试的研究。熔化温度、粘度、密度、比热容以及热导率和电导率的测量通常没有放在一起或详细讨论，特别是对于含燃料的盐。LiF、LiF-BeF2、LiF-NaF-KF、KCl-MgCl2、KF-ZrF4 和 NaF-KF-MgF2 跨越 70 多年的主要发现的原始数据已在此处整理和呈现。用于获得这些结果的方法的简要说明，除了作为燃料载体的这些盐中的一些的 TP 数据外，还进行了讨论。由于旧的、高误差的测量技术，热导率数据特别薄弱。最近用于评估盐热导率的测量系统有望获得一致的绝对值。本文得出的结论是，瞬态热线法、强制瑞利散射和激光闪光分析等测量​​系统最有希望填补这些数据空白，并降低燃料和非燃料熔盐热导率测量的当前不确定性。最近用于评估盐热导率的测量系统有望获得一致的绝对值。本文得出的结论是，瞬态热线法、强制瑞利散射和激光闪光分析等测量​​系统最有希望填补这些数据空白，并降低燃料和非燃料熔盐热导率测量的当前不确定性。最近用于评估盐热导率的测量系统有望获得一致的绝对值。本文得出的结论是，瞬态热线法、强制瑞利散射和激光闪光分析等测量​​系统最有希望填补这些数据空白，并降低燃料和非燃料熔盐热导率测量的当前不确定性。
