Abstract

Abstract:

[Background] The molten salt is used as the coolant of the molten salt reactor because of its stable chemical properties and excellent heat transfer performance. At the same time, the thermal stability of the molten salt also determines the stability of the molten salt reactor (MSR). In this paper, the effect of additives on the thermal stability of molten salt at high temperature was studied by selecting Solar salt (NaNO₃-KNO₃, 60%(wt)~40%(wt)) molten salt as a base salt and Na₂CO₃ as an additive.[Purpose] This study aims to improve the working temperature range and high temperature thermal stability of Solar salt molten salt.[Methods] The effect of Na₂CO₃ on the working temperature range and thermal stability of Solar salt was studied by the simultaneous thermal analysis and the mass loss rate-time curve. The decomposition products of Solar salt were verified by chemical analysis and pH analysis.[Results] By adding 1%(wt) Na₂CO₃, the working temperature range and thermal stability of the Solar salt molten salt were improved by 20 degree celsius and 3.2%, respectively.[Conclusion] This study can provide a reference to the improvement of high temperature thermal stability of molten salt in MSR.

Key words: Solar salt, Thermal stability, Molten salt reactor
